For shrimp farmers, high-quality post larvae are one of the key foundations for achieving productive pond performance. However, identifying good quality post larvae is often a challenge. This article breaks down the essential signs shrimp farmers should pay attention to when selecting post arvae.
With the right information, you can choose post larvae with the best potential to support the success of your shrimp farming operation.
What Is Quality Shrimp Post Larvae?
Quality post larvae are generally defined as PL with a high Survival Rate (SR), indicating strong adaptability to environmental changes. High-quality post larvae usually come from superior broodstock raised in hatcheries that apply strict operational and biosecurity standards.
Reliable hatcheries carefully record the development of shrimp larvae at every growth stage. If any issue occurs, such as delayed growth by 1-2 days or mortality at a certain stage, it will be documented and evaluated. These issues can later affect shrimp performance during grow-out, including slower Average Daily Gain (ADG) or lower SR.
Once shrimp larvae reach the post larvae (PL) stage, they are considered ready for delivery to ponds. During transportation, it is crucial to follow proper biosecurity standards and minimize travel time as much as possible. Before postlarvae are handed over to farmers or stocked into ponds, their quality must be thoroughly checked.
