In shrimp farming, seed quality plays a decisive role, accounting for up to 50% of the success rate of a crop. If the seed stock does not meet standards, shrimp are more likely to suffer losses, grow slowly, become stunted, and be sensitive to the environment, leading to many risks for farmers. Therefore, the nursery stage for shrimp seed plays an important role, helping increase survival rates to 95%, reduce costs, and improve farming efficiency.
WHAT IS SHRIMP SEED NURSERY-REARING?
Shrimp seed nursery-rearing is the intermediate stage between larval rearing and commercial grow-out. This stage aims to help shrimp seed adapt to the farming environment before being transferred to the grow-out pond. After nursery-rearing, shrimp develop better resistance, have a higher survival rate, a lower risk of disease, and achieve a more uniform size when stocked.
BENEFITS OF SHRIMP SEED NURSERY-REARING
- Increase survival rate: Thanks to rearing in a controlled environment, shrimp experience less shock when transferred to the grow-out pond, helping improve survival rates.
- Reduce seed losses: Nursery-reared shrimp before stocking reduce the risk of losses, especially due to environmental changes.
- Save costs: Reduce seed losses, limit the need for seed replacement, and reduce pond treatment work.
PROPER SHRIMP SEED NURSERY-REARING TECHNIQUES
Preparing the nursery pond
- The nursery pond is usually a hapa, cement tank, or composite tank.
- Clean the pond, dry it, and equip it with aeration and oxygenation systems.
- Fill the water through a filtration system, adjust salinity, and add EDTA (10 ppm) to help maintain water quality.
Care and management
- Nursery density: 500 - 1,000 shrimp/m³ (pond), 1,000 - 3,000 shrimp/m³ (tank).
- Feed the shrimp commercial feed 3-4 times a day, supplemented with digestive enzymes, minerals, vitamins, and essential amino acids.
Stocking transfer
- Prepare the grow-out pond well before transferring the shrimp.
- Carry out stocking transfer in the morning or late afternoon/evening, working quickly to avoid causing shock.
- 2-3 days before transfer, open the roof cover so the shrimp can get used to natural light.
Nursery-rearing shrimp seed not only helps shrimp farmers increase their success rate but is also an important solution for reducing costs and ensuring sustainable crop productivity.
