Biochemical response has been evaluated in the ovary of Channa punctatus (Bloch) after 135-day exposure to sub-lethal concentrations (0.1 and 0.2 mg/1) of zinc. Changes in glycogen, cholesterol, total proteins and total lipids were estimated. All these parameters showed significant depletion. Results are directly proportional to dose and duration of the experiment. Results indicate that exposure to zinc for prolonged periods may also reduce fecundity of fish, thereby limiting the numerical size of the succeeding generations.Keywords
