Abstract

Biochemical composition such as total carbohydrates, cholesterol and proteins in ovary of a freshwater fish Oreochromis mossambicus were studied with respect to heavy metal chromium toxicity. Disparity in gonado-somatic index (GSI) of this fish was also observed. Significant changes in the biochemical contents (p<0.05) and GSI (p<0.001) were observed during this study. Diminution in total proteins was 1.36 ± 0.63 mg/g whereas significant elevations in total carbohydrates and cholesterol (0.59 ± 0.47, 364.17 ± 54.26 mg/g respectively) and in GSI (6.89 ± 0.30) as compared to the control fish were noted. These variations in biochemical constituents and GSI during the present study may be an indication of stress caused due to toxicant chromium.
