Histopathological, hematological, condition-factor, and organ weight changes associated with selenium accumulation in fish from Belews Lake, North Carolina

Green sunfish (Lepomis cyanellus ) were collected from two study sites in Belews Lake, North Carolina (USA), for assessment of correlations between several biological parameters and bioaccumulation of selenium. The fish had elevated concentrations of selenium in the hepatopancreas (liver) and exhibi...

Description
Summary:Green sunfish (Lepomis cyanellus ) were collected from two study sites in Belews Lake, North Carolina (USA), for assessment of correlations between several biological parameters and bioaccumulation of selenium. The fish had elevated concentrations of selenium in the hepatopancreas (liver) and exhibited histopathological and other manifestations of selenium poisoning. Condition factors of Belews Lake fish were significantly correlated with selenium concentrations in hepatopancreas and skeletal muscle, indicative of capilary permeability changes and resultant edema, supported by the occurrence of significantly increased hepatopancreas-weight-to-body weight ratios in the fish having the higher tissue selenium levels.
