According to Binh Dinh Fisheries Sub-Department, in this province, many shrimp farming areas under the extensive farming method, the environment in the cultured water areas is seriously polluted, because the farming area has not been properly planned, which is the main cause of the epidemic. shrimp disease. In fact, the planned shrimp farming areas in Binh Dinh are few, and the spontaneous shrimp farming areas with weak infrastructure are many. The extensive shrimp farming areas do not have a separate water supply system into the pond and a separate wastewater discharge system, most of them only have one pond and then discharge it directly into the environment, leading to infectious pollution. lan. In the context of seriously polluted farming water, causing continuous diseases for shrimp, many whiteleg shrimp farming households in the form of intensive and semi-intensive farming in Phu My district (Binh Dinh) have filtered water before put in ponds. Contamination of culture water is the main cause of disease for shrimp. Photo: Vu Dinh Thung. The filter tank is built of cement bricks with a width of 6m, a width of 4m, and a depth of 2m. Underneath the tank is a layer of coral rock, followed by a layer of activated carbon and a thick layer of sand on top. Water is pumped from the underground circuit into the filter pond and then discharged into the pond with a large plastic pipe. Pump and filter continuously until there is enough water in the pond. After being filtered, the water is clear, when entering the pond, there is little change in algae. Every 3-5 months, shrimp owners have to change the sand and coal layer once. The 1-year coral layer must also be removed, scrubbed clean and then put back in the tank to avoid contamination of the culture water from the scum in the filter tank. The model of using water filter tanks for shrimp farming has been applied by many whiteleg shrimp pond owners in My An commune (Phu My district). Breeding fish in a dual-effective shrimp pond For shrimp farmers in Hoai Nhon town (Binh Dinh), raising mullet in shrimp ponds to help the fish clean the pond environment, both to limit environmental diseases on shrimp, and to earn more income from fish. . According to Mr. La Dong Quang in block 2, Tam Quan ward (Hoai Nhon town, Binh Dinh), one of the three pioneers in raising mullet in shrimp ponds has degraded in the model developed by the Binh Dinh Agricultural Extension Center. deployed with an area of ​​12,000m2, the number of mullet fingerlings stocked is 12,000 with the size of 200 fish/kg. After 8 months of stocking, the results showed that the fish grew well, the survival rate reached nearly 90%, the average weight reached 2-3 fish/kg, the estimated yield was more than 4.8 tons. Mullet has delicious meat, is popular with consumers, so the output is very generous. Mr. Pham Van Chay, a shrimp farmer in Dong Dien hamlet, Phuoc Thang commune (Tuy Phuoc district, Binh Dinh) releases monotypic tilapia into shrimp ponds to clean the pond environment. Photo: Vu Dinh Thung. According to Mr. Do Minh Quang, Deputy Director of Binh Dinh Agricultural Extension Center, farming households must manage environmental factors during the farming process; regularly monitor watercolor, identify environmental factors, monitor environmental factors. Monitor the health and pathology of the mullet fish to take timely measures. The water level in the pond is always maintained above 1.2 m, the amount of water changes from 20-30%/time, the time of water change depends on the level of pollution in the pond. Use aerators and aerators to maintain optimal dissolved oxygen levels in the pond, especially after sunset. In the first time of the farming process, only run the fan in the evening, when the fish are large, depending on the total weight of fish in the pond, adjust the running time of the fan accordingly. The shrimp’s food is always left over at the bottom of the lake, when the aerator runs aeration, the excess food pops up, the mullet fish just like that, so they can take advantage of the fine food source, and the fish will grow faster. Photo: Vu Dinh Thung. “Especially, mullet is omnivorous, the main food is organic detritus. This feature is very beneficial for cleaning degraded shrimp pond environment. In addition, the technique of raising mullet is not difficult, there are few diseases, so the survival rate is high. Breeding mullet interspersed with shrimp at a ratio of 1/4 will bring double profits on the same area, and at the same time reduce the time and cost of fish feed. Because the shrimp’s food is always left over on the bottom of the lake, when the aerator runs on the aerator, the excess food expands, the fish just keep on snapping, so they can take advantage of the refined food source, and the fish will grow faster. Breeding mullet in degraded shrimp ponds has given double results, both cleaning the environment in the pond to ensure safe shrimp growth and creating more income for farmers,” said Mr. La Dong Quang, farmer. mullet in a shrimp pond in Hoai Nhon town shared. In the shrimp farming area in the direction of biosecurity in Dong Dien village, Phuoc Thang commune (Tuy Phuoc district, Binh Dinh), in the shrimp ponds, tilapia can be stocked with the density of 1 fish/2m2 so that they to clean the pond bottom and ensure the water source for farming. “Tilapia not only gradually eat waste at the bottom of the pond to help limit pollution, but the slime layer of the fish also secretes substances with biological effects to kill harmful bacteria of shrimp, balancing the ecology in the pond. Thanks to that, shrimp farming in Dong Dien in recent years has not been harmed by diseases, farmers are profitable,” said Pham Van Chay, who has 4,500m2 of water surface area for whiteleg shrimp farming in Dong Dien village. shall.

At this time, the peach season begins. On the streets, traditional markets or “web markets”, peaches are sold in abundance. However, in addition to Sa Pa peaches, smooth peaches, gold hearths, crows, … new types of strange red crows appeared in the market. According to the clues, this is a Chinese peach, the outer skin is dark red, the inside is yellow, the sweet crunchy taste is no different from the Vietnamese peach. Due to its fancy look, large fruit and beautiful code, this peach is being bought by housewives to eat, even though the retail price is up to 100,000 VND/kg. Strange peaches with dark red skins flood the Vietnamese market Chinese suckling mangoes are selling well amid the high harvest of Vietnamese mangoes As noted by the reporter of Nguoi Lao Dong Newspaper, recently, the Ho Chi Minh City market “re-exported” the motorbikes peddling mangoes, also known as ripe yellow mini mangoes, quite similar to Chinese sucking mangoes, attracting quite many buyers. This mango is sold for 25,000-30,000 VND/kg. Mr. Nguyen The Bao, Director of Suoi Lon Mango Cooperative (Dong Nai), this year, Chinese mangoes ripen early, hitting the Vietnamese mango season, so competition is fierce in both domestic and export markets. Meanwhile, domestic mangoes are in full season and cheap. An Giang low-seeded mango is 9,000-15,000 VND/kg, precious quarter mango is only 15,000 VND/kg, Vip Taiwanese mango is only 7,000 VND/kg… On the “web market” instead of selling by weight as before, Mangoes are now sold in sets of several pounds or in boxes. Japanese octopus whiskers super cheap price, full of online market Octopus whiskers are firm, sweet, crunchy, and are loved by many people. The price for each kilogram of Japanese octopus antennae, officially imported, is VND 800,000 to VND 1 million. Cheap octopus whiskers are sold widely online. However, according to Dan Tri Newspaper, recently, on the online market, many small businesses sell giant octopus antennae advertised as Japanese goods at super cheap prices, from only 90,000 VND/kg. If customers buy in bulk, the price is only 80,000 VND/kg and free shipping to your home. Many people suspect this type of octopus whiskers may be made in China, not from Japan. Tiny cabbage priced at 400,000 VND/kg causes fever Cabbage is a familiar vegetable in Vietnam, with prices ranging from 10,000-40,000 VND/kg. However, according to Dan Tri Newspaper, recently, a tiny cabbage, only about the size of a plum, is being sold for 400,000 VND/kg, making housewives crazy. This type of cabbage, whose English name is Brussels Sprouts, originates from Belgium, is grown in many countries such as Australia, France and is a high-class product with many nutritional values. Goat pearls priced at half a million are still sold out Goat jasper is the testicles of a male goat. Since ancient times, jade yang goat was “praised” as a “panacea” in the bedroom. Dishes from pearl goats are increasingly popular. Ngoc Duong goat stir-fried with lemongrass and chili (Photo: Dan Tri) Ms. Vu Nhien (longtime goat meat restaurant owner in Quang Ninh) said on Dan Tri Newspaper: Currently, each set of goat pearls costs from 300,000-500,000 VND, depending on the size. Coil price increased sharply Major domestic steel brands have simultaneously announced to increase the price of CB240 coil to over 18,000 VND/kg. This is the third increase in the price of coil in May. Only in May, steel price has increased by about 10%. Since the beginning of the year, coil prices have increased 15 times, a total increase of about 40%. The sharp increase in steel prices makes it difficult for construction contractors to implement fixed unit price contracts and will incur losses. The first fruits of the season are simultaneously discounted Although the season has just started, many fruits at the beginning of the season are retailed in the market at much cheaper prices than in previous years. If at this time last year, the first crop of crocodiles was sold for 60,000-70,000 VND/kg, this year the price suddenly cooled down, only 40,000 VND/kg. The price of young crocodiles is much cheaper than last year The price of early season fabric is also cheaper than every year. For example, at the beginning of last year’s season, the price of pink lychee was 100,000 VND/kg when it arrived in Hanoi, this year it is only 50,000 VND/kg. On the online market, there are people selling cloth for only 50,000 VND / 3 kg. In Ho Chi Minh City, the price of Hanoi plums for sale is only from 40,000-50,000 VND/kg, half the price of plums at the beginning of last year’s season. Durian has just popped up and arrived in many markets in Ho Chi Minh City for about 2 weeks now, but the price is extremely cheap, about 60,000-80,000 VND/kg (food bag). Great price melons, pumpkins for cows to eat bò Due to the impact of the Covid-19 epidemic, the output of cantaloupe was affected, causing the price to plummet. Ho Chi Minh City Law Newspaper information, in some markets in Ho Chi Minh City and on mobile vehicles, melons grown in fields and greenhouses are being sold for only 20,000-40,000 VND/kg, not equal to 50% of the selling price in recent years. Pumpkin prices also dropped dramatically. According to Dan Tri Newspaper, the price of pumpkin in Dak Lak is only about 800-1,500 VND/kg, causing many farmers to suffer. In Phu Yen, hundreds of tons of pumpkins are piled up without buyers and have to be fed to the cows. Cheap Chinese ice cream flooded the market According to ANTV, at the beginning of the hot summer, domestic Chinese ice cream sticks with cheap prices of only a few thousand dong flooded the market and on social networks. Cheap, colorful and attractive, these ice cream sticks are sought after by many people without knowing the real origin and quality. In fact, all of these products are imported into Vietnam through a small quota, so there are no documents on the source of goods as well as product quality control. Therefore, many small traders in Hanoi have to open many warehouses, in order to divide the source of goods, to bypass the eyes of the functional forces. Wholesale pork prices drop sharply, retail markets drop trickle According to Ho Chi Minh City Women Newspaper, for about a week now, in Ho Chi Minh City, the price of live pigs has decreased by about 8,000-9,000 VND/kg. The price of thin pork (wholesale/jaw) of grades 1 and 2 also fell sharply by about 12,000-15,000 VND/kg, to 85,000 VND/kg grade 1 and 78,000 VND/kg grade 2, respectively. mixed with snakehead has not much decrease, only about 5,000 VND/kg. The retail price of pork in some markets is still high, some places only decrease by about 5,000-10,000 VND/kg, some places do not decrease. Specialty chili ‘regiment’ expensive price Unlike the scene where farmers in Binh Dinh, Quang Ngai, Quang Nam, … have to sell chili at a cheap price, this occasion in Muong Te (Lai Chau), the regiment’s chili specialty has the highest price. sharp. Chili regiment towering prices. Ms. Nguyen Thi Su – a regiment chili grower in Kan Ho commune (Muong Te) – said: “Last year, the price of chili fluctuated from 150,000 to 220,000 VND/kg depending on the quantity and time, but this year the chili crop failed. so the price is higher. I buy wholesale from 5kg with the price of 220,000 VND / kg, sometimes the retail price of fresh chili is up to 280,000-300,000 VND / kg, customers still compete to buy. According to Ms. Su, the reason for the regimental chili’s name is to refer to their spiciness, which means that the whole regiment only ate one of these chili peppers because it was too spicy. In addition, this type of chili also has a unique aroma that makes anyone who eats it remember forever. Old, broken computer components are sold at high prices Recently, the component market has become much more active because many people buy computers for the purpose of mining coins, Dan Tri newspaper said. Even old, broken components are also bought and sold at relatively high prices. To mine bitcoin, players need to invest in a highly configurable machine, especially, the graphics card must be very strong. The price of graphics cards has now increased by 30% compared to before. According to the business world, if virtual currencies hit the bottom as before, the price of computer components can return to the true value. Hanh Nguyen (Synthetic)

Eel farming according to new model. (Photo: Anh Tuyet/VNA) Farmers in Can Tho city are very excited because intensive farming of field eels using water circulation technology has helped them stabilize their livelihoods and get rich with typical products. This is a research achievement that has been implemented into reality by scientists of the Can Tho University . Associate Professor, Dr. Pham Thanh Liem, Head of the Department of Freshwater Aquaculture Technology, Can Tho University, Head of the project, shared from the fact that eel farming households in Can Tho are implementing two projects. farming, with soil and without soil with plant media or bamboo/nylon blisters all have limitations. Because, for the farming model with land, the stocking stock is large in size, often using natural seed, the food used is trash fish or homemade food, low density, eels hiding in the mud become a hindrance in the management of feed and health of farmed eels. In landless farming model , if it is an eel obtained from the wild, the growth and yield are lower than the land culture model. The rate of water change in both farming methods ranges from 1-1.3 times/day with 100% fresh water. Both of the above methods give low eel farming productivity of less than 10kg/m2. If the stocking density is increased, the water exchange rate will increase and increase the risk of disease, environmental pollution and food safety. Since 2018, the research team has implemented the intensive farming model field eels by water circulation technology. This is a model that meets food safety and traceability requirements, while maintaining environmental quality and protecting natural resources. The strength of the model is the application of technical and biological solutions, self-cleaning and reuse of water sources, increasing the maximum eel farming density up to 600 fish/m2 and increasing productivity to 25kg. commercial eel/m2. The productivity of farmed eel also increased from 2.5-4 times compared with conventional farming model; profit efficiency is from 36.5-60.2%. Households raising eel under the new model ensure safe operation, control of pathogens, health and quality of farmed eel products; minimize the rate of water change, increase the output of cultured eel; improve and increase the growth rate, eel quality and production efficiency; allows the treatment of contaminated water and helps control the discharge process. Thereby, contributing to environmental protection; forming and developing farming technology to create clean, high-quality products, meeting the needs of consumers. Currently, the model is starting to be transferred and deployed in a number of breeding and commercial eel farming sites in Can Tho city. Mr. Nguyen Thanh Tan, owner of Binh Thuy farm, Long Tuyen ward, Binh Thuy district has implemented the eel farming model in the form of water circulation since 2019, on a test area of ​​30m2, including 5 tanks, each tank is 6m2. The culture tank is designed to connect to the water circulation system including a biological filter tank, a solid waste settling tank and a water tank. The flow of water through the aquarium is adjusted from 0.5-0.8 liters/min. Black nylon rope is tied into a beam with a length of 20-30 cm, used for sheltering eels. This cord is cleaned daily and renewed once a month. Model of an eel tank based on water circulation technology. (Photo: Anh Tuyet/VNA) Eels are incubated for 90 days, size from 1.4-3.2g/head. Eel feed is industrial pellets, with 41% protein content. Instead of having to change the water every day like the old model, in the water recirculation model, the water is changed every 2-3 weeks. This helps farmers reduce labor costs, water costs, as well as help stabilize the water quality of the aquarium, and the eels are healthier and faster. After 8-9 months, commercial eels can reach 400g / head, farmers’ profits doubled compared to the old model. “In the commercial eel farming group of Binh Thuy district, there are currently more than 10 households out of 40 members who have switched to raising eels using water circulation technology. In general, the model is quite easy to install, the initial cost is The income is not high. The members are aware of supporting each other in farming techniques as well as product output. Therefore, most of the farming households give quite positive feedback,” said Mr. Tan. According to Associate Professor, Dr. Pham Thanh Liem, in the near future, the model will be replicated in Ninh Kieu and Phong Dien districts. The purpose is to support farmers to increase the technology content in farming and farming.

Food of field crabs must be fresh, not stale, moldy. Need to feed the field crabs enough, if the crabs lack food, it is easy to eat each other. Ms. Nguyen Thi Huong, Yen Tho commune, Dong Trieu district, Quang Ninh province harvests field crabs from her family’s farm. In ponds and fields, it is necessary to arrange a number of eating floors to assess the crab’s catching status, and at the same time to adjust the amount of food according to weather conditions. In the last months of the crab farming cycle, it is necessary to add more animal food in the diet to make the crabs grow fast and firm. It is possible to add more field tilapia and tilapia to eat crab leftovers, reducing water pollution. Field crab is the type that adapts to cool weather, so it is necessary to alternately plant water spinach, rice, and cash crops to keep the crabs’ shade in the summer. The water environment also needs to be kept clean and regularly change the source of water in and out to stimulate crabs to molt and catch strong prey. “Investment capital for crab farming is very low, mainly hiring workers to dig ponds, buy corrugated iron and bamboo poles to enclose the embankment. Currently, every day, my family earns about 3-4kg, selling 150,000 VND/kg ‘, Ms. Huong revealed. Through research, seeing that field crabs are popular with many people, taking advantage of low-lying rice fields for low productivity, Ms. Nguyen Thi Huong studied and brought back field crabs to release on her field. Because field crabs have no place to produce seed, they have to buy from people who go wild. Ms. Huong said: “At first, I bought crab seed from traders from Hai Duong to release, but each release the number of dead crabs was up to 70%. After a few dead crabs, I learned from experience that if I want to have a high survival rate and grow up quickly, I have to buy native breeds…” “In addition to raising commercial crabs, I also zoned the field and selected some adult crabs to breed separately. Here I will invest in buying brick holes to build banks, planting many layers of concrete pillars, with The purpose is to let the crabs live in, creating a favorable environment for the crabs to grow and develop better”, Ms. Huong added. Talking to us, Ms. Nguyen Thi Huong, Chairwoman of the Farmers’ Association of Yen Tho Commune (Dong Trieu Town, Quang Ninh Province) said: “Ms. Nguyen Thi Huong’s model of field crab farming has brought high economic efficiency. . From the initial results, in the coming time, the Commune Farmers’ Union will direct the grassroots branches, exchange experiences, and mobilize people in the commune to replicate this model. Especially, taking advantage of low-lying areas and inefficient rice-growing areas to develop commercial crab farming models, contributing to increasing income and improving the lives of members and people.

The opening hours of the shop can be at five o’clock in the morning or sometimes earlier. At five o’clock in the morning, Uncle Ba called to buy a pack of cigarettes. There are times when Mr. Bay comes over to buy tea bags and comes back to drink in the morning. Sometimes the night has completely sunk, the surrounding landscape has been quiet, the aunt of the two houses also often calls the door, buys a few packets of noodles, she complains that she has nothing to eat in the afternoon, so she “feels sorry”. My mother’s “notebook” is very thick. It was a student notebook, my mother used it to record who still owes some money from the shop. Every family in my neighborhood works in the fields, and it takes more than three months to harvest rice when there is a shortage of rice, fish sauce, monosodium glutamate, and sugar, so they have to “buy on credit” and wait until the rice season. Perhaps my mother’s way of doing business is very special, so when she has money or is short of money, everyone visits her shop. If you sell mango, add more mango, if you sell eggplant, add some onions, when you buy garlic, my mother will add chili. And yet, when anyone goes to buy things, carrying a child, when leaving, mom often carries a candy or a cake. The kids in my neighborhood love hanging out in front of my mom’s grocery store. When they were tired, my mother would scoop them up for a refreshing cup of iced tea. They like to enjoy a glass of shaved ice made by my mother. Because if you have money, you can pay it immediately, if you don’t have money, ask for another meal. Supermarkets are now full of big markets, but the whole neighborhood never forgets to support my mother’s grocery store. Because of the kilograms of “gratitude” rice when there was a shortage of rice, I sold it to the season. Or the meager tamarind to cook sour soup, my mother said, just a little bit, don’t take money. Or how can they forget that my mother’s love has taken all the money from the sale and lent it to Aunt Tu to take him to the hospital for an acute appendectomy… No matter how life develops, the village friendship is always cultivated as a beautiful cultural feature of the river delta of my hometown. People can’t live forever with nostalgia, but good memories can’t be forgotten. My four brothers and sisters have grown up with their mother’s hands, from the income of a small roadside shop. Miss my mom’s grocery store!

The process of raising Ca cuong according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. Sharing about her start-up journey from the Ca cuong farming model, Ms. Nguyen Thi Lan said that Phuoc Chi commune is considered a pure agricultural commune, so people here mainly grow rice and since childhood she has been attached to it. with fields, garden vegetables, frogs, frogs…; in it, there is a Ca cuong However, due to the changing habitat, the wild Ca cuong is gradually disappearing in the wild. In 2015, through researching on the information pages, she learned that Tay Ninh has successfully propagated Ca cuong in captivity, so she came to buy seed for trial at home. Through many times of raising and propagating Ca cuong failed because she did not know well about Ca cuong species, but with determination, not discouraged, she finally understood the technical process of raising Ca cuong. At the end of 2016, she has invested in 10 ponds with 2,000 breeders. In 2017, she started selling the first batch of Ca cuong and was popular with consumers. The benefits brought back far exceeded the plan with the average price of 30,000 – 130,000 VND / commercial Ca cuong and 100,000-200,000 VND / Ca cuong seed. According to Lan, Ca cuong is a fast-reproducing species with large numbers and lays all year round. Each birth is only 1 – 1.5 months apart / litter. Each nest of Ca cuong has about 100 eggs, after 5-7 days the eggs hatch into larvae, the hatching rate is nearly 100%. From hatching to commercial sale about 45 days, while raising for spawning about 75 days. Currently, Ms. Lan’s Ca cuong farm has an area of ​​3,000 m2. Raising Ca cuong is not difficult, but multiplying Ca cuong herds is not easy because Ca cuong is very sensitive to the environment, especially pesticides, in order to raise Ca cuong, it is necessary to choose a cool place, the water source is not polluted. . Therefore, farmers need to continuously monitor the growth and reproduction of Ca cuong to adjust appropriate care to achieve the best results. However, according to Lan, the food for Ca cuong is fresh food such as fish, baby frogs, and baby frogs, so when the food is not consumed, it is easy to pollute the water source. To ensure that the water source for raising Ca cuong is clean enough, farmers must change the water regularly. In addition, the process of growth from hatching to maturity, they undergo 5 molting, each time the farmer has to follow up to remove the embryo, so it takes a lot of time. The process of raising Ca cuong according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. In early 2020, by learning about the aquaponist model (a combination of aquaculture and hydroponics grown hydroponics), she realized that this model was suitable for her Ca cuong farm. Investing in building 30 more Ca cuong ponds with a scale of nearly 10,000 fish and stocking dozens of pounds of fish, along with 1,000 m2 of organic vegetable gardens to produce under a closed process. Ms. Lan shared, when applying the aquaponist model, Ca cuong, the food of Ca cuong (which is a fish) and vegetables will be grown in the same circulatory system. Ca cuong eats food and produces waste products in the water. Water containing waste is fed into mechanical and microbiological filtration system. Thanks to the participation of beneficial bacteria, the wastewater from the aquarium will be converted to organic nutrients into vegetable growing tanks, vegetables absorb nutrients in the water, then purify the water and provide backwards. back to the Ca cuong and the spiny fish tanks. As a result of the application of aquaponist technology, Lan’s Ca cuong herd grows healthier, the wastage rate is low, thereby saving 30% of the cost of food for Ca cuong, 50% reduction in the amount of clean water supplied. daily and 70% reduction in labor force. Ms. Lan also said that each month, her Ca cuong farm supplies to the market more than 10,000 commercial Ca cuong, after deducting the cost, bringing in profits from 40 to 50 million VND per month. In addition, thanks to the reduction of input fees, the source of Ca cuong seed sold by Ms. Lan is also 40% lower than the market price. The process of raising Ca cuong, growing aquatic vegetables according to the Aquaponist model of Ms. Nguyen Thi Lan brings high economic efficiency. According to Ms. Lan, at present, consumers are mainly aware of products processed from Ca cuong meat such as fried, steamed … because Ca cuong meat and eggs contain many proteins, lipids and vitamins. However, the most valuable of the Ca cuong is the bag of essential oils in the belly of the male Ca cuong. Foreseeing this, in addition to selling Ca cuong seeds, meat, realize that Ca cuong fish sauce is one of the products that still preserves the essential oils of Ca cuong, the delicious and fatty taste is accepted by the market. Lan continues to invest in production lines and fish sauce processing to diversify products from Ca cuong, increase value and have more stable output while more and more businesses and farmers invest. to cultivate this insect. In order to build a brand for the product, capture the One-Commune Program (OCOP), right from the moment the program was launched, she applied for the Ca cuong fish sauce product called “Phong Lan”. . Since registering for the certification of OCOP products, a good reputation, many companies, businesses, and supermarkets have come to find out about the product and more and more orders are placed, Ms. Lan chalk. Khoi said.

Red-eyed carp are raised by many households in streams, with high economic efficiency. A villager in the commune said that he had an affinity with this fish farming. Once he visited a friend in Sa Pa district, Lao Cai province, he saw that people here raise fish in a stream a lot, with little maintenance costs, and easy to sell. When he returned, from the water in the stream near his house, which flowed all year round, he started to raise fish. He chose the rocky slot and dug 4 fishponds with a total area of ​​up to 5,000 m2. In the midst of a pond, he worked more to bring water from the stream. The fingerlings were bought by him from hatcheries, including simple tilapia, carp, grass carp, etc., so the quality of seeds is always guaranteed. In Sin Thau commune, people raise fish entirely on elephant grass, banana leaves, maize and pureed cassava, without using pellets or industrial bran. Therefore, the quality of commercial fish here always ensures the clean element, firm meat, which is favored by many people inside and outside the region. Some households earn more than 200 million VND a year from fish farming taking advantage of the stream flow. But in Khanh Hoa province, where for many generations of Raglai people, T’rin people only know how to catch stream fish, hunt porcupines, and now there are suddenly fish farms with “nationality” all over Europe and Australia . It is a life-changing story in Son Thai commune, Khanh Phu, Khanh Vinh mountainous district. Going to Da Tay mountain area, beside Se Ooc stream (Son Thai commune), visiting Khanh Vinh cold water fish farm, everyone was excited. Between the four mountains and forests, dozens of large and small aquariums with 6,000m2 of water surface to raise sturgeon, snow grouper look very superficial. According to the farm’s technical manager, the cod grouper is a luxury fish, specializing in cold water living in Australia, but brought here still to live well. This farm also breeds sturgeon. The fish here grew faster than the fish raised in Da Lat. Sturgeon in Da Lat raised from 15 to 18 months to be sold, but here only 12 months, the fish had enough weight to bring to the market. Also in Khanh Phu commune, beside the winding Yang Gang, the fish farm of more than 1 ha is leaning against Treo hill (New hamlet), the scene is also very interesting. The fish farm seems to fall into a valley, far from residential areas, but close to the stream, with an area of ​​10,000m2 of water surface. Starting in 2018, the fish are in good season, grow well and give high income. Currently, each kg of fish sold at the source is more than 200,000 VND, about 10 tons of fish per month for sale. Farmers said that in order to get results today, people have gone through many difficulties. At the time of stocking, everything was favorable, the fish grew quickly. But in the first season, when it was ready to sell (each one from 1.6 kg – 1.7 kg), it suddenly died in mass. The fish farmer was shocked. But if they stop, all enthusiasm is considered to be dissolved into smoke. In the end, we gathered and reworked and then learned from experience, so the following cases all gave good results. Raising fish in streams is the most difficult, unfortunately, when it comes to sudden floods. At that time, it was very difficult to protect the fish from overflowing. Therefore, during the rainy season, fish farmers have to take turns “on duty”, if the rain is heavy and the water rises, they must immediately notify everyone to take care of them. The streams are still the same for thousands of generations, but if you have determination, have capital, learn experience and techniques, fish farming here will bring a great source of income.

Farm operators say animal welfare is guaranteed when salmon are kept in shallow pools as they are swimming in artificial water. Photo: Smart Studio. In the row of indoor swimming pools there, 5 million adult salmon were swimming passionately away from their home town. pass cold water fish to a hot area This is a Atlantic salmon species, famous for cold water in Norwegian fjords or in cold water lakes in Scotland. They are not native to hot and warm Florida, so in order to cope with the completely different weather where they were born and the ideal environment to grow, the aquarium is cooled, housed in a large building. cold and of course very good insulation. The building is named the Green House, which has just come into operation in phase 1 since last year. When completed, it will be the largest salmon farm in the world. The investor is the Atlantic Sapphire Company, said the current output of the farm is 9,500 tons / year, and when the farm is operating at full designed capacity – it is expected that by 2031, the output will increase to 222,000 tons. If so, about 41% of the American’s salmon demand each year, or 1 serving serving, would be supplied domestically. Atlantic Sapphire is currently one of the pioneers of the trend of investing in terrestrial and indoor aquaculture. The company is headquartered in Norway. “When we came up with this idea 10 years ago, a lot of people were talking so crazy,” said Johan Andreassen – CEO of the company. “At that time, no one believed that bringing cold-water salmon to terrestrial farming could or was financially viable. The advancement of technology dispelled their doubts. Johan Andreassen introduces salmon farmed in Green House. Photo: Atlantic Sapphire. According to Andreassen, Atlantic Sapphire has proven successful in technology, now only dealing with financial viability and how scalable it can be effectively scaled. Salmon farming in shallow tanks – Pioneering technology New technologies equipped for the Green House to operate are not unfamiliar, but the investment rate to ensure profitability has only been achieved in recent years. The building is equipped with a recirculating aquaculture system called RAS, controlled from data on temperature, salinity, pH, oxygen level, flow, and light in the water. The tank also has an automatic mechanism that removes CO2 and waste and water into a filter for treatment and reuse. Raised in a closed process, salmon is immune to diseases and parasites found in the natural environment, so Atlantic Sapphire does not need antibiotics or other drugs. “Compared to marine farms, we guarantee fewer incidents of disease, the death rate is also among the lowest,” said Neder Snir, chief technician of AquaMaof in Israel. This is the company that provides technology for Atlantic Sapphire and about 10 other businesses around the world. “We ensure farmers do not need vaccines or antibiotics. This technology ensures disease isolation and control of the farming environment ”. Atlantic Sapphire has invested $ 400 million into their US facility in a total of $ 2 billion in funding plans. By 2031, they expect to own a 372,000 square meter aquarium on the 65-hectare project area. Why is it America? A Norwegian company that invests in large farms in Florida raises the question of purpose, especially when the culture is in doubt or does not guarantee the welfare of the chosen fish. According to the Atlantic Sapphire, they ensure a closer supply to the US market instead of bringing fish from Europe to by plane, in addition to taking advantage of the natural conditions endemic to the southern state. Florida sits atop two layers of water – one is the surface freshwater layer, the other is the lower saltwater aquifer. Trout need a freshwater environment in the early stages of growth, larger than they need salt water. In the Green House, the technology system ensures these two water sources. Here, wastewater is pumped into deep underground rock under the salty water layer separated from useful aquifers, so it does not pollute the area’s common water source (only at a very small rate compared to the government’s regulations. ).

The supply chain right in the US enables customers to traceability and create confidence in the end product without having to go through many stages of virus infection. Also, the transport stage is not congested when the cost of the road increases dramatically due to the impact of the epidemic. Atlantic Sapphire salmon has become familiar with American consumers. Last year, the brand “Green House Salmon was sold for 12 USD / kg, 2 times higher than imported Norwegian wild salmon. Would that worry salmon farmers and exporters in Nauuy and Scotland? Ragnar Tveteras – Professor of Commerce at Stavanger University (Norway) explains in a detour: “I think there is a challenge of using energy, about CO2 emissions, but I still do not have enough data. Demand (farmed fish) does not bother me too much, it is important that the price will probably go up ”. And Alan Tinch, technical head of the fishing services firm Benchmark Genetics in Scotland, predicts a change from Scottish farmers to adapt. “Maybe they will transfer the fry to an indoor farm, when healthy, they will be brought back to the natural marine environment. The wild fish still has its quality and location ”. The Green House project is not really smooth, even though it is advertised as a pioneer in technology. In July 2020, a water quality incident forced the company to harvest 200,000 salmon early before they were 20 months old. In March this year, fish also died abnormally and at the beginning of April there was a gas leak incident causing 3 workers to be hospitalized. Animal Rights Protection PETA criticizes the Green House project and about 40 other businesses developing terrestrial aquaculture farms, including a planned seabass farming project in Arizona. “Fish can feel, think, can know pain or joy, they belong to themselves, not people,” said Dawn Carr, Project Director of (food) vegetarian PETA said. “This fish farming is cruel.” But Director Johan Andreassen argues that the criteria for animal welfare, at the Green House, are fin shape and swimming speed, which is continuously and fully controlled by the company.

“For me, this is a special trip, marking the maturity and experience of youth”. Having dreamed through Vietnam for the past three years, Tung said he wants to discover interesting things in the provinces and cities as well as challenge his limits. Cao Bang man took a commemorative picture with young people in Ha Giang. When making a decision about a trip across Vietnam, Tung was initially met with objections from his family. However, parents know that their son is a person with a strong personality, when deciding to do it to the end. Then, they nodded in agreement and gave him some little advice. Before starting the trip, Tung spent about 2 months preparing. The first month, he planned, planned itinerary, studied the way, maps. Before that, the boy also actively practiced physical training, jogging, and exercising. In addition, thanks to night operations during his enlistment, Tung has more experience and flexibility when hiking. Even to show his determination, before the trip, Tung sold the only motorbike as a toll. “From a young age, I still went to the forest, climbed mountains, worked in the fields to help my parents. When I get sick, I just need to climb a mountain, I naturally get better, no need to take medicine. Over time, my sincere calluses, I no longer feel pain ”. Every day, Tung departs from 6 a.m. to 12 a.m., and in the afternoon, from 2:00 p.m. to 6:00 p.m. One day, he walks on average 30 km. It was almost dark, Tung asked to sleep in the people’s house. If he could not, he could find a place to sleep on the hill or in the forest. “At the beginning of the trip, I learned to get used to the changing weather, sometimes hot weather, sometimes heavy rain. On the first day, I had to climb 13 kilometers of the pass. At that time, although tired, I still tried hard, determined to overcome “. Thanh Tung started his journey across Vietnam from the top of Lung Cu, Ha Giang. Walking alone through Vietnam has many risks. However, Tung is not worried. He thinks that walking can exercise both strength and have time to visit, talk and get to know many people. In addition, Cao Bang does not put much time on completing the journey. Moreover, he did not consider his trip to be a corpse. Because wherever he goes, he stops to visit, take photos, and record videos of people and sights to make memories. Currently, after 10 days of starting his journey, Tung has moved nearly 500 km. At first, everything went quite smoothly. Wherever he goes, Tung receives the help of everyone. On the first day of walking in Dong Van, Ha Giang, Tung was allowed to sleep by a local resident, and then given a hat by the children. In particular, during the journey, Tung was most impressed by a Spanish racer, Josep, visited, encouraged, and accompanied him throughout the long haul. All left in the 25-year-old boy unforgettable emotions. Although knowing that the journey is still long, difficult and challenging, Tung affirms that he will never give up, to waste his youth. For him, this trip is a turning point to become more mature, to equip the road ahead. “There are 3 words to say about who I am dreaming, persistent and passionate. I am a person who always daydreams doing things that many people consider impossible. In addition, I am always persistent, determined to prepare for personal plans “.

The provincial Ha Tinh there are more than 7,000 ha of citrus trees, of which orange and pomelo trees account for nearly 90%. The most cultivated area for pomelo trees is in Phuc Trach, Huong Trach and Huong Do communes (Huong Khe district), while the orange area is mainly concentrated in Vu Quang district up to 2,500ha, Thuong Loc commune (Cam Loc district) is 240 ha.

Land for planting oranges and pomelo This area belongs to the group of red and yellow feralit soil and an area of ​​basalt soil formed on hilly or mountainous terrain interspersed with high mountains, very hot summer climate, on average 380C, cold winters and rainfall. Large, suitable for grapefruit, orange trees.

However, in the agronomy of pomelo and oranges, there are many limitations due to the unscientific use of fertilizers, farmers rarely invest in organic fertilizers, use too much acidic chemical fertilizers such as supe, phosphorus, nitrogen, etc. or types of fast-soluble NPK containing acid root for fertilization, intercropping legumes for land investment is limited, and in the rainy season, soil is very large.

As a perennial tree, pomelos and oranges in Ha Tinh lack nutrition and sour environment, thus reducing productivity, appearing harmful pests and diseases. Before 2010, the brand name of Phuc Thach pomelo and oranges in the market was faint. The area of ​​orange cultivation has narrowed, the gardeners’ income has decreased sharply … in order to restore the brand, regain productivity and quality, Ha Tinh province has focused on investing in building a fertilization process according to the VietGAP standards.

Understanding local needs and shortcomings in the use of fertilizers by farmers, Van Dien Fused Phosphate Joint Stock Company cooperates with Ha Tinh Gardening Association to deploy many models. using Van Dien fertilizer for pomelos, oranges and safe vegetables on the table in Huong Khe, Vu Quang, Duc Tho …

Trial on Van Dien fertilizer in pomelo production areas of Phuc Trach, Cam Khe May, Thuong Loc, Cam Bu Huong Son.

The experiment was conducted in a closed crop year 2010 on 1.5 ha of 15 year old grapefruit in Phuc Trach, together with 2.0 ha of 10 year old oranges in Khe May and Huong Son by using completely Van Dien fertilizer including Fused phosphate fertilizer and NPK multi-factor fertilizer is used specifically for citrus. Van Dien fertilizer divided fertilizer 4 times a year:

• Stage 1: Applying after harvesting, using 1.5 – 2.0 kg / root of Van Dien fused phosphate + multi-element of NPK 5.10.3, from 2- 4 kg + 15 kg of decomposed organic fertilizer /origin.

Phase 2: Applying flowers with the amount of fertilizer from 1.0 -1.5 kg / root of ĐYT NPK 12.5.10.

Stage 3: Applying after fruiting from 2.0 to 3.0 kg / root of health care NPK 12.8.12

• Phase 4 fertilizing 50 days before harvesting fruit from 1.5 -3.0 kg / root ĐYT NPK 12.7.20.

Grapefruit fertilized with Van Dien is more prominent than the control along with other NPK fertilizers in that: Bright green leaves, shiny leaf surface, thick leaves, smooth bark and branches, 50% reduction of harmful pests and diseases. high fruiting, fruit uniformity, concentrated ripening, beautiful peel color, less fruit drop, yield 1.8 times higher than control, sweet and fragrant quality characteristic of Phuc Trach grapefruit and famous Buu before. After only 10 years, farmers have liked the effectiveness of Van Dien Fertilizer

Mr. Nguyen Xuan Tinh – Chairman of the Gardening Association of Ha Tinh province said, “Since the introduction of Van Dien fertilizer, orange trees, grapefruit trees here are fully supplemented with nutrients, healthy plants, good growth and development. With high yield and quality, up to now, Ha Tinh province has thousands of hectares of citrus trees fertilized with Van Dien fertilizer ”.

Mr. Hoang Van Giam, Phuc Trach commune, Huong Khe district, said: “My family has 200 grapefruit roots 10 years old, in the last 6 years, I completely use Van Dien fertilizer, every year grapefruit has good season to sell. After fertilizing a healthy grapefruit tree, wrong flowering, large fruiting, uniformly large fruit, less drop, reducing pests, yield, high quality, Van Dien fertilizer contains much more nutrients than other types. Fertilizer is currently on the market, in Phuc Trach most people use Van Dien fertilizer.

Ms. Pham Thi Lanh, who has 500 oranges and is 13 years old, commented: “Van Dien fertilizer with good quality, competitive price, convenient supply, easy to use, high efficiency, great profit. More than 7 cases of oranges in the family completely use Van Dien fertilizer, the most difference is the color of the leaves, the shade is visible from a distance, dark green, after heavy rains, the trees are very few to drop fruit, the stools are good and durable. , good quality, high productivity, high quality, easy to consume, especially less using plant protection drugs, safe for users, protecting the environment ”.

In the Buu orange growing area in Son Mai, Son Thuy, Son Truong communes with more than 1,000 hectares, Mr. Ngo Xuan Hoa, Son Mai commune, cultivating 300 orange trees, shared: “The family has tested many fertilizers for orange trees, but Only Van Dien fertilizer is suitable and easy to use fertilizer. Van Dien fertilizer is more than other fertilizers, it is full of 13 types of nutrients to meet the needs of orange trees, so plants are healthy, less pests, high yield and quality ”.

Van Dien fertilizer helps plants to be healthy, less pests, high yield and quality

Bringing Van Dien Fertilizer back to people growing safe vegetables in Ha Tinh.

Recently, the demand for safe vegetables of consumers is very large, small farming methods, heavy using chemical fertilizers and pesticides have been replaced by more scientific farming methods. according to VietGAP standards, cultivating safe vegetables, clean vegetables, organic vegetables. The vegetable growing land in Ha Tinh is mostly on alluvial soils that are poor, humus and acidic, pH

The appropriate time for nursing Ha is late February and early March of the lunar calendar.

Hanging string farming is most developed in Hoang Tan commune. Currently the whole commune has thousands of rafts of oysters, large and small. Over the past 10 years, many households in Hoang Tan island commune have developed their economy, enriched by raising oysters.

Previously, the farming of Ha was fragmented, mainly the way of raising on tiger parrot branches, both ineffective and affecting the ecological environment of the mangrove area. Since 2011, a number of households have tried farming by driving piles to the tidal flats, then tie the piles together into trusses and hang up skewer.

Mr. Truong Van Ket, Chairman of Hoang Tan Commune Farmers Association, said: From a few experimental farming households, up to now, the commune has nearly 1,000 households raising hanging ropes, with a scale of over 4,000 hectares of water surface. In this form of farming, they have a fast growth rate, a high survival rate of 80-95%, and a harvest of about 5,000 tons / year.

Working as oyster farming, hanging rope is not too hard, but it requires experience. The farming process is very simple, just take advantage of the exploited shells, bring them to dry in the sun, then punch a hole in the shell to skew to the rope and release. Depending on whether seed is obtained from the wild or from imported seed sources, farmers will create potting ropes with suitable density.

Mr. Nguyen Van Bong’s family in village 5, Hoang Tan commune has been attached to the farming of stringed stringers for more than ten years. Like many other families here, at the end of February, the beginning of the third lunar month is when his family and other households start to breed Ha. In the morning, when the water is dry, people take advantage of tying the skewers of mint to the truss, waiting for the tide to rise. These skewers will become the substrates for the seed in nature to cling to.

After about 2-3 months of nursing, the seedlings have grown to the size of their fingers, people begin to separate each cord to hang to create conditions for the hippopotamus to develop. Each cord has about 5-6 children, hanging about 10-15cm apart. When high tide floods the hanging piles, the tidal currents of the Ha stick cling to the crust and grow and develop on their own. Ha will eat the plankton, algae in the water to grow. So oyster farming does not cost much to buy food and take care like other types of seafood.

However, Mr. Bong also shared that this job is much affected by weather conditions and water salinity, so the risk is quite high. Sometimes, the whole crop will disappear if the water source is polluted, and the disease will die. On the other hand, if the stocking is too dense, it can make the galaxies look fatter for a long time, the harvest time is extended for several months, leading to the higher rate of death.

Model of raising ocean on raft.

The time to switch from summer to autumn when the weather is cold is the time when the hanging rope grows fastest. Farmers have to calculate the tidal water to move the rafts to the farming area with lots of algae to feed them. Usually around November of the lunar calendar begins to harvest.

Compared with wild extraction, the hanging rope model is 10 times more effective, while the initial investment cost is not much, and easy to harvest. Ha in Hoang Tan is of better quality. Because of the mixture of soil, water and soil, the Ha is fat, thicker than the cultured in other localities.

Oyster farming not only brings about great economic value but also benefits in environmental protection. Oysters and mussels purify water through their breathing, and they also eat microorganisms and plankton that make seawater cleaner.

Since the occupation of hanging string, the life of the island commune people gradually changed their flesh. Hoang Tan has become a supplier of oysters, mussels and other aquatic species to a large number of the province, and is famous for its fresh and greasy oyster products. This is also one of the key products of Quang Yen province in implementing the OCOP program, one product per commune and ward.

And when mentioning Hoang Tan, people will immediately remember the profession of hanging rope – a profession that attaches to the lives of coastal people, lives on the sea, contributes to the protection of the marine environment and receives precious gifts. prices from the sea.
