Diet variably affects the trophic transfer of trace elements in the oyster Crassostrea gigas
International audience Although it has been shown that trophic transfer of trace elements in oysters can be influenced by the diet, most of the studies investigating the ability of oysters to bioaccumulate trace elements from their diet are based on experiments using phytoplankton alone. Wild oyster...

Interestingly, no significant difference was found among estimated depuration rates (kel) for all trace elements ingested with the two diets tested.
