Influence of food on the assimilation of essential elements (Co, Mn, and Zn) by turbot (Scophthalmus maximus)
International audience Food is an important route of metal uptake in marine organisms and assimilation efficiency (AE) is a key physiological parameter that can be used to systematically compare the bioavailability of different metals from food. This parameter may be influenced by various factors, i...
