Diagnostic criteria for proliferative hepatic lesions in brown bullhead Ameiurus nebulosus.

Brown bullhead Ameiurus nebulosus is used as indicator species for contaminant effects at areas of concern (AOC) in the Great Lakes and other areas. One of the beneficial use impairments at numerous AOC is 'fish tumors and other deformities'. An impairment occurs when the prevalence of fish tumors and other deformities exceeds those at unimpacted or control sites or when survey data confirm the...

Pollution-induced behavioural effects in the brown bullhead (Ameiurus nebulosus).

Aquatic ecosystems are major sinks for pollutants which can have adverse effects on biodiversity. Thus, it is important to understand the nature of pollution-induced change in aquatic ecosystems. We show that brown bullheads (Ameiurus nebulosus) may have evolved in response to chronic pollution exposure. We collected adults from the Detroit River (polluted site) and Belle River (control site). ...

Cumulative impacts assessment along a large river, using brown bullhead catfish (Ameiurus nebulosus) populations.

The effects of point-source and diffuse discharges on resident populations of brown bullhead catfish (Ameiurus nebulosus (LeSueur, 1819)) in the Waikato River (New Zealand) were assessed at sites both upstream and downstream of point-source discharges. At each site, the population parameters, relative abundance, age structure, and individual indices, such as condition factor, organ (gonad, live...

Biomarkers of oxidative stress and genotoxicity in livers of field-collected brown bullhead, Ameiurus nebulosus.

The objective of this investigation was to determine whether differences in a suite of biomarker assays in brown bullhead liver tissues could be detected and related to the pollution histories of two Ohio locations, one a reach of the Black River that had historically been severely impacted by the effluents of a coking plant, the other at Old Woman Creek, a freshwater estuarine research preserv...

Glutathione S-transferase expression in pollution-associated hepatic lesions of brown bullheads (Ameiurus nebulosus) from the Cuyahoga River, Cleveland, Ohio.

In rodents, overexpression of glutathione S-transferase pi is a characteristic feature of foci of cellular alteration (FCA) and neoplastic liver lesions induced by genotoxic chemicals. Alterations of glutathione S-transferase (GST) expression in hepatic lesions have also been reported in fish exposed to environmental carcinogens, and cellular GST expression may be an important determinant of gr...
