Assimilation and retention of metals in teleost and elasmobranch fishes following dietary exposure
In a radiotracer study designed to evaluate the fate of metals from fish prey to predator fish, we measured the trophic transfer of 7 trace elements (Am, Cd, Co, Cr, Cs, Mn, Zn) from juvenile Mediterranean sea bream Sparus auratus to 3 predator species, the teleosts Psetta maxima and Sparus auratus,...
