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.

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.

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.

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.
