Abstract

The effects of an organic-inorganic chemical contaminant mixture were evaluated on percent fertilization, percent hatch, and prolarval survival of striped bass. All dilutions of the mixture simulated concentrations of various organic and inorganic contaminants found in striped bass spawning habitats. The organic contaminants were Aroclors® 1248, 1254, 1260, chlordane, DDE, chlordecone (kepone), toxaphene, anthracene, benzo(a)anthrene, chrysene, fluoranthrene, fluorene, perylene, pyrene, and phenanthrene; inorganic contaminants were arsenic, cadmium, copper, lead, and selenium. Percent fertilization (24-hr exposure) and percent hatch (48-hr exposure) were not significantly affected by exposure to various dilutions of the contaminant mixture. The full-strength contaminant mixture (all chemicals as listed in Table 2) significantly reduced survival of striped bass prolarvae after 144 hr continuous exposure from the time of spawn. A masked effect may have occurred during initial embryo development that was later observed in the prolarvae.
