摘要：

The lethal effects of a chemical molluscicide, copper(II) tetraoxosulfate(VI), on Clarias anguillaris and Bulinus globosus were investigated. The fish were exposed to various concentrations of the chemical in a 48, 72 and 96-h static bioassay, while the exposure time for the snails was 24 h. The LC50 for the various treatments were calculated after corrections were made for natural responsiveness. The molluscicidal concentration was found to be lower than the piscicidal concentration. The histopathology of the gills of the fish revealed a general damage of the gill filaments probably leading to impairment of ion and oxygen uptake. © 1990.
