Comparing single-feeding and multi-feeding approach for experimentally assessing trophic transfer of metals in fish
International audience Diet is an important pathway for metal uptake in marine organisms, and assimilation efficiency (AE) is one of the most relevant parameter to quantify trophic transfer of metals along aquatic food webs. The most commonly used method to estimate this parameter is pulse-chase fee...

International audience Diet is an important pathway for metal uptake in marine organisms, and assimilation efficiency (AE) is one of the most relevant parameter to quantify trophic transfer of metals along aquatic food webs.

The present work aimed at validating the approach by assessing single-feeding and multiple-feeding approaches, using a model species (the turbot Scophthalmus maximus).
