Gonadal histopathology following nickel intoxication in the giant gaurami Colisa fasciatus (Bloch and Schneider), a freshwater tropical perch
- Univ. of Gorakhpur, Uttah Pradesh (India)
Large variety of data regarding toxic effects of nickel on mammals has been reported. Nickel refinery workers had increased mortality from lung or sinonasal cancers. In human populations exposed to nickel and chromium compounds, chromosomal abberations have been reported. Biochemical as well as histopathological alterations arising from nickel exposure in mammals have also been documented. Very scanty data is available concerning histopathological impact of nickel on fish tissues. However, to the authors' knowledge, there are no reports available on the fish gonads of either sex encountered with nickel. The present study appears to be the first report on the topic. Therefore, in the present investigation impact of nickel on the histological architecture of gonads of both sexes of a freshwater tropical perch, Colisa fasciatus have been assessed.
