Impact of intensive larval rearing practices in oyster hatcheries : selective processes and loss of genetic variability (Poster)

Early-life history of oysters, like in most marine bivalves, is characterized by high fecundity and low survival rate. In hatcheries, which are ecoming more and more important for the production of juveniles for aquaculture production, rearing conditions are optimised (density, feeding, temperature....

Description
Summary:Early-life history of oysters, like in most marine bivalves, is characterized by high fecundity and low survival rate. 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.
