Introductory fact Sheet. Cold Blooded Animals with the exception of a known species (Great white shark) Highly fecund animals compared to other animal groups even for low-fecund fish species. Highly diversified group (finfish, crustaceans, molluscs, ...)
Hatcheries supplying fish for culture -based fisheries (CBF) need to consistently provide good quality (fit and healthy) juveniles suitable for stocking. Poorly planned genetic management of brood stock and breeding can result in: declines in the quality of stock over a number generations. reduced fecundity.
Jun 19, 2015 · Locate large releases of hatchery fish away from important natural production areas. This strategy helps to minimize negative interactions with wild fish and to decrease harvest risks to wild populations. Time hatchery fish releases to minimize ecological risks. The timing of release and out-migration should be considered.

Defining fish species according to salinity systems may lead to some confusions. Examples: When seeds are produced in marine hatcheries but grown in different salinities including freshwater (e.g. mullet/shrimp/European seabass) When seeds are produced in freshwater and grown in saline waters (e.g. tilapia)
