Alternative complement pathway assay data observed in adult largemouth bass plasma in response to an EE2 (17alpha-ethinylestradiol) or mixture of estrone and atrazine exposure under laboratory pond conditions, with associated fish identification information.
Field and laboratory data collected for fishes sampled by boat electrofishing in the Sacramento-San Joaquin delta, CA. This data release includes all measured environmental parameters, body composition analyses, otoliths, and fish taxa included in the analysis.
To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre-treatment (1988, 1989) and two years post-treatment (1990, 1992). The dataset contains Osprey reproductive parameters, foraging parameters, prey delivery rates and bald eagle piracy rates at eight intensively observed nests. Fish stocking records and creel data were obtained from the Oregon Department of Fish & Wildlife for both reservoirs...

Disease outbreaks, skin lesions, fish kill events, and reproductive abnormalities have been observed in wild populations of bass in the Chesapeake Bay watershed. Occurrence of synthetic and natural hormones from wastewater treatment plants and livestock operations, pesticides from agricultural lands, and phytoestrogens from cover crops have been implicated as potential causes of these adverse effects. Late summer to fall is the period of early gonad recrudescence in adult bass when spermatogenesis and oogenesis begin for the upcoming spawning event in spring. Our objective was to assess whether early gonad recrudescence was a period of sensitivity for inducing immunomodulation. Adult largemouth bass (LMB; Micropterus...
