Influence of the intermoult cycle on the metal bioaccumulation by the shrimp: Crangon crangon L.

At the various intermolt stages (A, B, C, D) the cephalothorax, abdominal muscle, exoskeleton and legs of shrimp Crangon crangon L.from the Seine Bay estuary have been analyzed for Hg, Cd, Cu, Fe and Zn. A statistical test of the results of the metal analyses, and the variations of the concentrations during the intermolt cycle are used to estimate to what extent the shrimp is a representative indicator of its environment.
