Abstract
Groups of striped bass Morone saxatilis eggs from several parental sources differed in their concentrations of HCB (hexachlorobenzene), DDTs, PCBs (polychlorinated biphenyls) and chlordanes. Survival of both starved and fed larvae was inversely related to concentrations of chlorinated hydrocarbons in these eggs. Changes in body burdens of these organochlorine compounds were calculated among larvae fed Artemia nauplii containing distinctive organochlorine residues. Accumulation from dietary sources of the organochlorines was more pronounced in larvae hatched from eggs with low parental contributions of chlorinated hydrocarbons. Among these larvae, body burdens increased in rough proportion to the cumulative amount of food‐borne contaminant ingested. Accumulation rates were highest for DDTs, followed by PCBs, chlordanes, and HCB. In larvae with high initial concentrations, however, only DDTs showed accumulation during the feeding period.Keywords
