National benthic surveillance project: Pacific coast. Fish histopathology and relationships between toxicopathic lesions and exposure to chemical contaminants for cycles 1 to 5 (1984-88). Technical memo
The report presents and interprets the results of histopathology studies conducted on 17 species of bottomfish captured at 45 sites between 1984 and 1988 as part of the Pacific Coast portion of the National Benthic Surveillance Program (NBSP) in conjunction with NOAA's National Status and Trends Program (NS T). The location of sampling sites ranged from Prudhoe Bay in Alaska to San Diego Bay in California, and incorporated sites. Twenty-three were located in or near urban embayments, and the 22 remaining sites were in nonurban embayments, five of which served as comparison or reference sites on the basis of minimal levels of sediment contaminants detected (Kamishak Bay, AK; Nisqually Reach, WA; and Bodega Bay, Dana Point, and outer Mission Bay, CA). These comparison sites were selected so that the same fish species could be collected from minimally contaminated environments as opposed to those obtained at urban or more contaminated sites. Six primary target species were identified for statistical analyses that examined the relationships between occurrence of particular toxicopathic diseases or lesions in the liver and kidney and levels of potential or actual exposure to contaminants. These species were selected because they were broadly distributed geographically and were abundant among the sampling sites, they had previously documented significant prevalences of contaminant-associated diseases, or the geographic distribution of similar diseases among the sites suggested an association with contaminant exposure. These primary target species were flathead sole, English sole, starry flounder, hornyhead turbot, white croaker, and black croaker. All specimens were examined for the presence of necrotic, sclerotic and proliferative lesions in the kidney, as well as lesions.
