Abstract
Reproductive activity of a Indian cat fish; Clarias batrachus has been studied from the ponds located in the district of lakes, (Bhandara). Progressive maturational changes except those depending on meiotic division occur after three months. The spermiogenesis in male is completed at the end of three months and shows sexual readyness only of adult stage. Similarly in females although the oocytes continue to enlarge and mature ova are formed in the adult condition. There is considerable relationship between temperature and composition of nutrient materials in the tissues of gonads and accessory reproductive organs. In the present study, Glucose, Protein, Cholesterol and Urea contents in the tissues of gonads and accessory reproductive organs increase in cold environment and decreases at higher temperatures.
