In the framework of the Science and Technology project, a group of researchers from the Faculty of Fisheries (Can Tho University) and graduate student Tran Dong Phuong An, for the first time successfully artificially reproduced freshwater striped fish. The striped fish is a catfish with scientific name (Pangasius macronema), this is a fish with high economic value in the market. Currently, this fish species occurs in the wild quite few and concentrated in provinces such as An Giang, Dong Thap, Vinh Long and Can Tho city. In order to develop the economy, recently, many farmers in some provinces in the upstream of the Mekong River have caught fish in the wild and brought back to raise them in rafts on the Tien and Hau rivers with industrial food for sale. commodity. Currently, striped fish is sold in the market at a high price of 120,000 – 130,000 VND/kg, while in restaurants the price is from 250,000 to 300,000 VND/kg. For the first time, successfully artificially reproduced freshwater striped fish. Photo: Le Hoang Vu. According to the project team, after nearly 4 years of research, this is the first time to successfully stimulate artificial reproduction of striped fish and it is expected that this breed will be replicated and provided to farmers in 2023. This was approved by the City Department of Science and Technology. Sponsored by Can Tho.

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.

Stuffed snails are currently a popular food in the market. Growing commercial stuffed snails is a new economic development direction, many farmers have escaped poverty to get rich. Stuffed snails are easy to raise, do not cost investment but give very high efficiency. Photo: LNC. Ha Son is currently one of the communes with the largest number of people and area for commercial snail farming (with 9 farming households) along with a lot of experience in aquaculture. such as Mr. Nguyen Xuan Bac 5 sao, Pham Hong Hien, Nguyen Xuan Hai (3 sao each), Mr. Tran Van Binh 4 sao… Many households in Yen Son commune (Ha Trung district) also raise snails stuffed with nets. , reaching an income of 35 – 40 million VND / sao (excluding costs), the profit is 2-3 times higher than that of some other aquatic products. Recently, Ha Trung District People’s Committee has implemented a model of linking commercial stuffed snail farming according to the value chain associated with product consumption in Yen Duong commune. The model for assessing the adaptability, productivity, income and economic efficiency of stuffed snails originated from Tam Phuc Aquatic Breeds Co., Ltd (Yen Dinh district), transferring technical advances to farmers. commercial stuffed snails, forming a chain of production and consumption of products. Before the implementation, 2 selected farmers, Mr. Le Van Tuy and Mr. Le Xuan Dau (Yen Duong commune) signed a commitment to participate in the implementation of the model (along with 20 other households in the commune) approved by the Center for Disease Control and Prevention. District Agricultural Service cooperates with District Farmers’ Association to train and disseminate technical knowledge on commercial stuffed snail farming. Accordingly, Mr. Tuy used 800 m2 of farmland for farming ponds, and at the same time received 80,000 seed snails; Mr. Dau uses 700 m2 of farmland to build a pond and receive 70,000 snail seed. Each nest of stuffed snails minus the cost, can give an income of over 60 million VND. Photo: LNC. Households participating in the model receive free support on seeds and techniques. Before stocking snails, the pond is dredged clean, sprinkled with lime powder to neutralize the pH in order to eliminate all kinds of carp, carp, and turtle that can eat snails. The pond bank is cleared of bushes to avoid nesting mice and convenient when harvesting. In ponds, put water hyacinth and water spinach to increase the coolness of the pond and create more places for snails to cling. The water level in the pond is maintained from 0.8-1.5m. The measured pH is 6.5 – 8; Dissolved oxygen reached the permissible threshold, the stocking density of snails was 100/m2 of pond, the weight was from 0.4 – 0.6 grams/individual. Selected snail seed are healthy, good quality, shell is not chipped, stamped, top shell is bright color. When stocking snails, take water from the pond and pour it into pots, drop the media (female duckweed, cassava leaves…) and put the snails in a pot to soak for 10-15 minutes to balance the living environment. pots and then slowly drop the seed snails into the pond gently to avoid building the shells and damaging the snails… The main food of stuffed snails is duckweed, green vegetables, cereals. Snails have the habit of both floating and living on the bottom, moving slowly and unevenly distributed in the pond, often concentrated in some areas in the pond. Therefore, it is necessary to create different terrains and depths to diversify habitats for snails and easily monitor and care for snails. Ha Trung district (Thanh Hoa) is aiming to build the farming of stuffed snails into commodity production, associated with OCOP products. Photo: LNC. After stocking snails until 2 months old, there is no need to change the water. To the 3rd month of culture, change the water once every 2 weeks, each time changing 3/4 of the water in the pond. In the households in the model in Yen Duong commune, due to good management and care techniques, snails grow well, evenly and healthy. After 3 – 4 months of farming, snails reach a commercial snail weight of 25 – 30 pieces/kg, then start harvesting. Use a boat to go around the pond to catch big snails (in the morning) because snails cling to plant leaves, cassava leaves, and duckweed roots to eat, so harvesting is easy… According to the calculations of the households in the model, minus costs, the profit reached 61 million VND/sao (an increase of more than 20 million VND/sao compared to current farming experience). In addition to economic efficiency, the technique of raising stuffed snails is quite simple, the care is not too complicated. The main food for snails is clean and easy-to-grow vegetables, raising stuffed snails has no adverse impact on the ecological environment… Ha Trung district has recently provided technical training for 70 farming households and households wishing to raise stuffed snails to continue replicating in the district, towards building product brands (OCOP). In the early morning, snails often float to the surface, clinging to cassava leaves and duckweed to eat, so farmers can know which areas are more concentrated, avoiding excess or lack of food. Food for snails must be clean, leave the whole plant, leaves, not chopped because snails have the habit of sticking to the surface of the leaves to eat. Only feed concentrates (cereals) once a day. Adjust the amount of food according to the snail’s ability to eat (from 0.5-1% of the snail weight in the pond).

Mr. Le Minh Hieu introduced the breeding model of black soldier fly. Mr. Le Minh Hieu said that 3 years ago he went on a business trip to An Giang province and knew about the black soldier fly breeding model. However, the models he visited were all models of dry farming with peat, waste and cow dung. With that way of raising, he saw many inappropriate points. Therefore, when he returned home, he researched and learned more about the characteristics and habitat of the black soldier fly larvae. After a period of research, Mr. Hieu has experimented with black soldier flies in a microbial culture mixture, with the principle of using microorganisms to treat odors, and overcome harmful bacteria to create beneficial bacteria. beneficial environment. Mr. Hieu used probiotics in combination with molasses and clean water and allowed newly hatched black soldier fly larvae to live in this environment. At first, Mr. Hieu had to buy black soldier fly eggs from hatcheries from An Giang province, but now he knows how to breed himself without having to buy outside. Currently, Mr. Hieu’s black soldier fly farm has an area of ​​about 200 m2, with each raising of about 1 gram of eggs, 300 kg of commercial larvae will be produced within 12 days. Mr. Hieu further shared, the life cycle of black soldier flies lasts more than 1 month, starting from eggs, larvae, pupae, and finally molting into black soldier flies. Adults live about 3-5 days, do not eat, live in the shade of trees. Black soldier fly larvae produce a substance that is detrimental to the laying and hatching of flies and other insects, making them an environmentally beneficial livestock and a very good food for humans. livestock and poultry. Nutritional composition in black soldier fly larvae before pupal stage is 43 – 51% protein, 15 – 18% fat, 2.8 – 6.2% calcium, 1 – 1.2% phosphorus, enough nutrients Nutrient for animal feed such as pigs, chickens, ducks…, and is the best live food for raising ducks, chickens, fish, shrimps, crabs… Fly larvae can be concentrated, dried and mixed with other substances. other nutrients as feed to completely replace fishmeal in the production of animal and aqua feeds. Mr. Le Minh Hieu uses commercial black soldier fly larvae as chicken feed to replace feed from industrial bran. Currently, with a culture of 300 kg of black soldier fly larvae / 12 days, with a mixture of hydrolysis of black soldier fly larvae, fish hydrolysis plus bean residue and micro-organisms, Mr. Hieu can completely replace the feed. industrial feed for 1,400 ducks, 400 chickens and hundreds of fish of all kinds being raised on the family farm. With this mix of feed, Mr. Hieu calculated less than 3,000 VND/kg of feed, over 50% cheaper than the current cost of 1 kg of industrial bran. Mr. Hieu compares, with about 1,000 ducks raised commercially, with the current price of industrial bran, farmers spend about 80 million dong of industrial bran for ducks from raising to slaughter. As for this method of raising from hydrolyzed black soldier fly larvae, it only costs about 35 million VND in food costs. “With this method of feeding from black soldier fly larvae, animals grow very quickly due to the high nutritional content of the feed, and the risk of disease is also significantly reduced. Therefore, it is very cost-effective in raising livestock and improving the quality of livestock”, Mr. Hieu added. According to the Agricultural Extension Center of Ba Ria-Vung Tau province, the use of insects in livestock production is very popular in the world. Black soldier flies are recognized by the Food and Agriculture Organization of the United Nations as the preferred insect species for waste treatment and use of protein content as an alternative to food for some livestock. Mr. Hieu’s model of raising black soldier flies is a relatively new and very successful model in Ba Ria-Vung Tau province.

The company has automated the voltage and frequency adjustment of the power system to ensure power quality; Reducing the amount of electricity that cannot be supplied to customers, creating more revenue for the electricity industry; Reduce long distance transmission and optimize transmission grid loss. Modernizing the development of electricity meters and remote metering data collection systems has helped to collect complete data on customers’ electricity usage, timely detect problems of the metering system. count. This technology also helps the Company closely monitor the electricity usage mode of customers, especially large customers, and at the same time serve to calculate the unit’s power loss accurately as well as the power loss of the station. public in particular. In addition, the Company also encourages customers to actively adjust or change electricity demand during peak hours. Thereby, reducing the maximum capacity of the power system, reducing the overload of the grid, contributing to improving the economic efficiency of the power system. At the same time, it will also create conditions for the community to be more aware of electricity saving and efficient use of electricity, contributing to the protection of national resources. Ba Ria – Vung Tau Power Company has implemented many measures to reduce power loss With the unremitting efforts of all employees Ba Ria-Vung Tau Power Company in the control of power loss in particular, the rate of power loss continuously decreased from 2015 to 3.97% at 22kV level; in 2019 is 1.75% (including 110kV level) and in 2020 is an impressive number: 1.57% (including 110kV level). With the mission “ Electricity is one step ahead ”, BRVT Power Company has actively invested and upgraded the power grid system, ensuring safe and reliable power supply for tourist centers such as Thuy Van beach (Vung Tau City), Long Hai beach. (Dat Do district), Ho Coc – Ho Tram resort (Xuyen Moc district)… Every year, the Company focuses its capital to invest in preventing overload and strengthening the power grid; Electric islands for industrial shrimp farming, irrigation pumping stations to fight against drought, concave areas without electricity, removing fishing tackle… to meet the demand for irrigation for agricultural production and aquaculture. fisheries and tourism development in the province. Doing a good job of reducing power loss makes a lot of sense. help reduce production costs, increase profits for the company and increase the efficiency of production and business of the unit.

The prices of clean meats at supermarkets are more expensive than in traditional markets, but still remain at the old prices. At traditional markets, supermarkets, food products, green vegetables and basic necessities are still plentifully sold, but according to many small traders in Hanoi, goods are consumed slower than in Vietnam. there are no cases of COVID-19 infection in the community. Purchasing power in the market decreased by 20-30% compared to before the epidemic. “Currently, Thai mango prices are still stable, delicious types are sold at 45,000 – 50,000 VND / kg, medium types from 35,000 – 40,000 VND / kg; Saigon mango prices range from 60,000 to 65,000 VND / kg. The price of imported apples has inched more. If in the past, the price was from 90,000 – 100,000 VND / kg, now it increases by 10,000 VND / kg; Delicious type is currently selling for 150,000 VND / kg. The price of Envy apple is from 180,000 to 200,000 VND / kg, an increase of 10,000 – 20,000 VND / kg compared to before ”, said Pham Thi Ngo, a fruit trader in Hang Bun street, Hanoi. According to Ms. Pham Thi Ngo, due to concerns about translation, purchasing power decreased from 30 to 40% compared to before, because people are less likely to go to the street. Number of customers buying by phone is negligible, except on the first and full moon holidays. In the hot weather, the price of oranges and tangerines increased from 5,000 to 10,000 VND / kg compared to before. Saigon orange price is 60,000 VND / kg; sweet tangerine is 70,000 VND / kg. Due to an outbreak, many restaurants and eateries were empty, so the consumption of goods was slower than before. “The necessities and food are many, but now many restaurants have to close due to the absence of customers, prolonged epidemics, so food and food are now abundant and the price is even softer”, Ms. Nguyen Thi Mai Lien – cottage said Dong Xa market, Mai Dich ward, Cau Giay, Hanoi. According to the owner of a fresh fish stall at Lo Lua “toad” market, Bach Mai street, the price of many types of fish is 5,000 to 10,000 VND / kg cheaper than before. Tilapia is currently sold for between 40,000 and 45,000 VND / kg, depending on the type; red roses 58,000 VND / kg, down 2,000 VND / kg; carp 67,000 VND / kg, down 3,000 VND / kg; carp 60,000 VND / kg. “About 1 week back, people went to the market less everyday because they bought food together for 3 days or 1 week. Normally, with fresh produce like fish, many housewives only buy goods for stock for 3 days, ”said Lien Hoa, a small trader selling fish in Lo Lua“ toad ”market. Goods are flooded at the supermarket. From the beginning of the year until now, the price of beef and pork has not fluctuated, even “cooled down”. At the traditional market of Phan Huy Chu, the price of billed beef remained at 310,000 VND / kg; beef tenderloin is 350,000 VND / kg; corn meat 350,000 VND / kg; Corn flower core from 420,000 to 620,000 VND / kg, depending on type. In some “toad” markets in Hanoi, the price of pork decreased slightly compared to before. Currently, the price of lean meat is 140,000 VND / kg, down 10,000 VND / kg compared to before; ham meat from 110,000 to 120,000 VND / kg, down 10,000 VND / kg compared to before, especially fat reduced to 15,000 VND / kg at the price of 60,000 VND / kg. Sharing with the News reporter on May 10, Ms. Vu Thi Thanh Van (housewife), Bach Mai street shared: In recent days, food prices at Trai Gang market, Bach Mai street are still as stable as before. there is no translation of COVID-19 in the community. Accordingly, the price of raw chicken feathers is 120,000 VND / kg; choysum is 10,000 VND / kg; cabbage is 8,000 VND / kg; mosquito net 5,000 VND / kg, morning glory 8,000 VND / kg… Because I am afraid of translation, I go to the streets less and buy food for the whole week. COVID-19 lasted, so commodity prices decreased, but people’s spending also reduced more “, Ms. Vu Thi Thanh Van shared. Many supermarkets apply promotional goods to stimulate demand. As noted by the reporter of News, at supermarkets such as Big C, Hapro Mart, VinMart … goods are all full on shelves, commodity prices have not increased, not to mention there are promotions. great forever for customers. Visitors to the supermarket are checked their temperature, asked to wear a mask, hand sanitizer to prevent epidemics. Representatives of distributors and markets in Hanoi all stock up twice as much in warehouses to supply the market. Fresh food, essential goods to fully serve people, there is no shortage of “fever” prices. “Hanoi has prepared a large quantity of goods, serving the local people’s anti-epidemic needs. With the amount of goods in reserve for 3 months, 17 essential goods are worth 194,000 billion VND. Hanoi also reserves an amount of goods of nearly 30,000 billion VND to be ready to support provinces and cities in neighboring areas if complicated epidemics occur “, Ms. Tran Thi Phuong Lan – Acting Director of Department of Industry and Trade Ha Cabinet said.

Beluga fish is owned by Vietnam Sturgeon Group (CTVN) and has been raised since 2010 on farms in Binh Thuan, Dak Lak, Binh Dinh, Lam Dong, Son La. According to the representative of the group, CTVN has a stock of about 5 million fish, of which the Beluga sturgeon has a number of nearly 100,000, reaching a weight of 5-30 kg / fish, especially fish weighing up to 80 kg. CTVN is currently one of the few units that can breed sturgeon in Vietnam. In 2007, CTVN Group established sturgeon hatcheries in Vietnam, located in Tuyen Lam Lake, City. Da Lat. Broodstock were selected from fish farms in Germany and Russia. At the beginning of its establishment, the first batch of hatchlings were imported and technically supported by Russian experts. By 2010, when the first herds of fish matured, Caviar de Duc sturgeon eggs were on the market, considered the first batch of fish successfully propagated in Vietnam. According to the representative of the group, CTVN’s rearing procedures are followed by special technology consulted by leading Russian experts. In addition to meticulous care according to the scientific regime, CTVN’s farms are also located in hydroelectric reservoirs at an altitude of 500-900m, where there is great flow and clean water all year round, heat. The coolness is about 18-27 degrees Celsius, ensuring all parameters of water quality, environment no different from the natural growth zones of sturgeon in Europe. The production process of the CTVN farm system has been rigorously tested and certified to meet VietGap standards, and at the same time is continuously improving and consolidating the quality indicators system towards GlobalGap standards. As a result, sturgeon raised on CTVN farms retain its inherent natural taste, and the quality of meat and fish eggs is not inferior to that of wild caught sturgeon. Protect fish “million dollars” After more than 10 years of establishment and development, CTVN’s farm system has expanded with an area of ​​about 160,000 square meters. Previously, Vietnam had to import fish eggs from abroad, now CTVN can produce breed eggs by themselves. In particular, the fact that CTVN is a rare unit in Vietnam and Southeast Asia owning a rare and super-rare Beluga herd marks a major turning point in the development of our country’s cold-water fisheries. Beluga is one of the special sturgeon species, known as the “million dollar” fish because not only fish have high nutritional value, but their eggs are very rare. A mature Beluga fish for eggs in the natural environment requires 20 years of age and an adult weight can reach 900 kg. Beluga sturgeon eggs have a market price of between $ 7,000 and $ 10,000 / kg, among the top 10 most luxurious dishes on the planet. Beluga fish meat is delicious and firm, nutritious, healthy, is a nutritious dish with high content of calcium and phosphorus as well as protein, selenium, iron, magnesium and vitamins B12, B6, vitamin C, A and D and especially Omega-3 fatty acids. Regular use of sturgeon and caviar is beneficial for brain function, helps reduce the risk of depression, prevent heart disease, foster the body and restore health. However, in Vietnam, the number of people who have the opportunity to enjoy this rare fish meat is very few because there was no place in our country where Beluga could raise them for commercial purposes. In addition, this fish is an endangered species, so in the world, it is declining about 60% in the wild and is still the red listed fish. Therefore, having a unit like CTVN succeeding in breeding and breeding sturgeon in general and Beluga in particular has brought a lot of meaning in preserving nature, bringing economic and social values. According to CTVN, the group can bring to domestic and international high-end products including Beluga fish meat and Caviar (black fish roe) with great reach. CTVN Group currently has 6 member companies operating in the field of egg hatching and breeding, sturgeon rearing and black caviar production with Caviar De Duc brand – the brand named National Brand 2020.

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.

Wang Chunying, deputy director and spokesperson of the State Administration of Foreign Exchange.Source: China Net

Wang Chunying pointed out that the world economy has been gradually recovering recently, and major developed countries have implemented very strong stimulus policies, which will boost consumer demand to a certain extent. At the same time, liquidity remains abundant, so commodity prices are rising. Regarding this issue, my country is one of the major importers of bulk commodities, and the impact of price increases deserves our attention. Some scholars and media are also concerned, such as the issue of imported inflation.

Wang Chunying said that from the perspective of the foreign exchange bureau, we are more concerned about the impact of rising commodity prices from the perspective of international payments. For example, if import payments increase, what impact will it have on the balance of payments? We saw an increase in imports in the first quarter, but exports also achieved good growth. The trade in goods still achieved a surplus of 760 billion yuan, which was higher than the average level of the previous two years. Under this circumstance, the current account maintained a basic balance and a small surplus in the first quarter. It should be said that the overall balance of payments is still healthy.

Wang Chunying also said that the foreign exchange bureau will continue to promote the liberalization and facilitation of trade and investment, and there is no need to worry in this regard.
