For shrimp farmers, the art of stocking is crucial. The step from hatchery to pond can be fraught with peril for seed, and success in shrimp farming is often directly correlated with stocking methods. Here's a comprehensive guide on how to stock your shrimps for optimal success.
Stocking is more than merely transferring seed from the hatchery to the shrimp ponds — it's a series of meticulous steps that ensure the well-being and future productivity of the stocked Post larvae (PL’s)This process directly impacts the survival rate, health, and growth potential of shrimp stocks
There are several approaches to seed stocking, each tailored to specific conditions
The most straightforward, where seed is directly released into the pond.
Seed are acclimatized to pond water while in a tank before release.
A means of evaluating seed health before introducing to ponds.
Stocking at cooler times, in the early morning, reduces the risk of thermal shock and stress to the seed.
Clumping, slow movement, mortality, cannibalism among, and discoloration in the seed are signs of poor quality. Stocking such seed could result in high mortality rates and decreased productivity.
Perform visual checks and quality assessments prior to stocking. If the seed does not meet quality standards, delay stocking until healthier seed is available.
Accurate counting is crucial for determining the stocking rate. Employ multiple counters and average calculated numbers from batches to ensure precision.
Measuring survival rates is an essential aspect of stocking evaluation. A Hapa test provides reliable data on how well the seed acclimated to pond conditions.
To perform the HAPA test, use a prescribed number of seed, typically 100, over a specified period post-stocking. High survival rates indicate successful acclimatization.
Monitor and maintain optimal stocking pH and temperature to minimize stress on the seed.
Providing quality feed after stocking can help reduce post-stocking stress and support rapid growth.
Always make informed decisions based on data and observations. An adaptable stocking strategy is key to long-term operation success.
Implementing these best practices ensures that the act of stocking in your shrimp farming operation is not only a mere transfer of PL to the pond but a positive introduction to their new environment, encouraging survival and success. It is a careful balance of science and experience, and your dedication to these steps will reflect in the health of your shrimps and productivity of your farm. Keep in mind the various stocking methods, their nuances, and potential challenges to ensure successful stocking for your specific species and conditions.
