Estimating predation rates of restocked individuals: The influence of timingof-release on metapenaeid (shrimp) survival.

Brian Pooh*

Post-release mortality is one of the greatest obstacles in many aquaculture based enhancement programs [1-4], and often the downfall of stock enhancement efforts, regardless of great successes in hatchery culture. Predation is widely known to be a major factor in post-release mortality in hatchery-raised juveniles [5,6] accounting for up to 95 % of post-release mortality [7], and can quickly turn stock enhancement into an expensive exercise in making food for predatory species [8].
