At this time, coastal aquaculture farmers in Kim Son district are actively preparing conditions to enter the main aquaculture season of the year. This not only creates initiative in the farming process but also helps limit diseases, increase productivity and income for people.
Upgrade ponds, switch to intensive farming
On an area of 1 hectare, Mr. Pham Van Hao, hamlet 6, Kim Trung commune (Kim Son district) boldly invested billions of dong to renovate and plan the overall pond system and auxiliary items to serve the production of oyster seeds combined with shrimp breeding.
Mr. Hao shared: Many years of production experience show that if farming is done in an extensive manner, the risk will be very high, the farmed fish are susceptible to disease, the quality and size are not uniform... therefore, even though the initial investment is small, the profit is not worth it. Therefore, I decided to invest in upgrading the pond, completing the water and environmental treatment system to produce intensively, limiting diseases. Everything is ready, just waiting for favorable weather to start production.
Like Mr. Hao, at this time, Mr. Trinh Dinh Tu in Block 10, Binh Minh town is also urgently preparing for the new shrimp crop. Taking advantage of the clear weather, Mr. Tu hired more workers to clean the pond. Mr. Tu said: After each shrimp crop, during the care process, the excess food, waste and pathogens that settle and accumulate at the bottom and banks of the pond will pollute the pond environment. If not renovated and treated carefully, it is very easy for diseases to arise for the next shrimp crop.
Therefore, after each crop, I always renovate the pond by draining the water, spraying moss and dirt around the banks, soaking in disinfectants, and even washing the pipes. Along with that, I carry out maintenance, repair, and installation of necessary equipment for farming. "Nowadays, shrimp farming cannot be left to chance, because the weather and environmental conditions are increasingly harsh. We have to upgrade the pond, purchase advanced equipment, and regularly learn and apply new technical advances to care for and prevent diseases for shrimp. Like my family, before, we only had earthen ponds, but now we have upgraded to 7 floating ponds, covered with tarpaulins and roofs. Thanks to that, shrimp can be raised all year round, and the success rate is also much higher" - Mr. Tu shared.
In the coastal communes of Kim Son district, not only Mr. Hao's and Mr. Tu's families, but many other aquaculture households are also tending to invest heavily to upgrade ponds and convert to intensive and super-intensive shrimp farming.
Information from the Department of Fisheries, Department of Agriculture and Rural Development said: In 2023, the area of intensive and semi-intensive white-leg shrimp farming increased to over 300 hectares, including 75 hectares of super-intensive farming.
Strengthen environmental warnings and strictly control breeding stock
According to the plan, the total brackish water aquaculture area of Kim Son district in the Spring-Summer crop is 2,146.4 hectares. Of which: The area for extensive improved black tiger shrimp farming and brackish water fish farming is 1,451.9 hectares; the area for intensive and semi-intensive white-leg shrimp farming is 340 hectares; the area for clam and oyster seed production is 354.5 hectares.
Regarding the seed release schedule, for black tiger shrimp, seed rearing will start from March 15 to March 31, 2024. Based on the weather, seed release for commercial black tiger shrimp farming will start from around April 1, 2024.
For white-leg shrimp, start stocking from April to May. In particular, ponds with roofs that maintain temperature, have adequate infrastructure conditions, and good control of environmental factors can be raised through winter.
The Department of Fisheries recommends that, for the new crop to be successful, aquaculturists need to strictly follow technical procedures during the farming process. Especially the renovation and cleaning of ponds; choosing to buy juveniles at reputable addresses, with quality quarantine certificates from competent authorities. It is advisable to raise and use large juveniles for commercial farming; strengthen environmental management and disease prevention. At the same time, choose food suitable for each farming object and growth stage; do not use stimulants, chemicals, or antibiotics banned in aquaculture...
Mr. Pham Van Hai, Head of the Fisheries Control Station (Department of Fisheries, Department of Agriculture and Rural Development) said: Since the end of 2023, the unit has proactively coordinated with the Department of Agriculture and Rural Development of Kim Son district, the authorities of communes and towns to grasp the situation and progress of pond and lagoon renovation; regularly monitor and take water samples in farming areas to guide people to get the best quality water into ponds and lagoons. In addition, training courses on aquaculture techniques have been organized and the crop calendar has been disseminated to hundreds of farmers.
Good preparation of pond, lagoon and farming area conditions, ensuring quality of breeds and strictly implementing technical procedures according to the instructions of professional agencies are important initial steps for a successful Spring-Summer aquaculture crop, contributing to increasing people's income.
