Nitrogen and carbon isotopic relationships in the diet and eye lenses of chub mackerel revealed in a laboratory rearing experiment

Abstract The N and C isotopic compositions (δ15N and δ13C) of phytoplankton vary due to biogeochemical processes. The δ15N and δ13C values of fish tissue are inherited from the phytoplankton in the regions where the fish lived. The δ15N and δ13C values of fish eye lenses, which are an incrementally...
