(vasep.com.vn) Bac Lieu Department of Agriculture and Rural Development has been actively cooperating with provincial Verification and Testing Centers and Institutes for Aquaculture to find the cause of shrimp mortality. The results will be released in the upcoming time.
To limit disease infection, the agricultural sector recommended farmers to delay stocking time and should stock with low density: 15 pieces per square meter for black tiger shrimp and 50 pieces per square meter for whiteleg shrimp. The agricultural sector requested that farmers should build sedimentation pond and waste water treatment pond before discharging water into the environment, ensure shrimp seed before breeding and avoid using banned and untraceable chemicals in farming.
