Ensuring effective shrimp farming in the second crop

(Baonghean.vn) - Hoang Mai town has favorable conditions for aquaculture development, especially white-leg shrimp farming with a total area of ​​more than 475 hectares, of which the second crop of shrimp farming is more than 350 hectares concentrated in the localities of Quynh Di 86 hectares, Quynh Lien more than 53 hectares, Quynh Loc more than 71 hectares, Mai Hung and Quynh Xuan.

Up to now, Hoang Mai town has released 150/350 hectares of shrimp for the second crop.

After the success of the first shrimp crop in 2016, people were excited to start renovating and treating the ponds to prepare for the second shrimp crop. The most important step is to treat the ponds, the water must be filtered and settled to remove pathogens that cause diseases in shrimp.

After harvesting, the pond is drained of water and dried for 20-30 days, using 10-15kg of lime powder per sao and spreading it all over the pond to disinfect. Water is led from the river into the settling pond system, treated with chlorine to ensure cleanliness and clarity while pumping water into the pond to release shrimp. The settling pond accounts for about 20% of the shrimp farming area to settle sediment and treat the water source, limiting environmental pollution from the water source. From experience, some households in Quynh Di ward have had the initiative to drill wells and build water filter tanks to raise shrimp. The well water is drilled at a depth of more than 30 meters, so the salinity is less, not polluted, and limits disease sources from water pollution.

In addition to favorable weather conditions, many factors are needed: Water source, pond treatment process, breeds, food, care, disease prevention methods to help shrimp grow healthy and fast. Mr. Nguyen Van Gioi - Block Sy Tan, Quynh Di Ward said: "We have to prepare ponds for treatment according to the correct technical process, treat the water to be clean. Choosing breeds is also a decisive factor. During the farming process, we must take care of them, feed them with disease prevention medicine with biological products made from herbs, use vitamin C and additional minerals".

Many farmers are actively treating ponds to release shrimp for the second crop.

Up to this point, the town's residents have stocked nearly 150 hectares and are continuing to treat the ponds, completing the second crop stocking plan. According to the plan, the shrimp stocking time will start from the beginning of July to the end of August.

Mr. Hoang Ngoc Thuy - Head of the Economic Department of Hoang Mai town said: "To ensure the completion of the aquaculture plan, the most important thing is that the farming households release shrimp on time, ensure the quality of shrimp seeds, and are disease-free. The functional sectors and farmers strengthen environmental protection and disease prevention in farming areas according to biosafety shrimp farming processes, thereby increasing economic value. It is expected that by the end of October, the second crop of shrimp will be harvested."
