摘要

Studies were conducted in 1989 through 1991 to determine injury to herring in211u001ePrince William Sound following the Exxon Valdez oil spill. About half the herring 211u001eeggs deposited in 1989 were exposued to Exxon Valdez oil. Survival to hatch was 211u001enot impacted, but there were substantial sublethal effects (acceleration of 211u001eembryo development, morphological deformities and cytogenetic abnormalities) in 211u001enewly hatched larvae and reduced survival from hatch to free swimming. These 211u001ecorrelated well with oil exposure in adjacent mussels and paralleled experimental 211u001elaboratory observations. The relationship of oil to histopathological lesions in 211u001efeeding larvae from oiled areas was supported by laboratory studies. Severe focal 211u001ehepatocellular necrosis in 20% of adult herring examined from oiled areas (none 211u001ein unoiled areas) was probably due to viral hemorrhagic septicemia induced by 211u001eexposure of carrier fish to Exxon Valdez oil, and consistent with later 211u001elaboratory studies. Polynuclear aromatic hydrocarbons, probably Exxon Valdez oil 211u001ein origin, were detected in adult herring tissues.
