In hatcheries, which are ecoming more and more important for the production of juveniles for aquaculture production, rearing conditions are optimised (density, feeding, temperature...), and contrast with those observed in the wild. Additionally, slow growing larvae are culled by sieving. PY 2005 PD JUL ID 3444 ER EF
