AB  - The present investigation has been conducted to study the reproductive characterestics of the catfish, <I>Heteropneustes fossilis </I>(Bloch.) cultured in sugarcane bagasse substrate medium. Adult <I>H. fossilis</I> (av. wt. 194 g for males and 210 g for females) were reared at 20 tank<SUP>-1</SUP>. No feed was provided to the fish in three of the substrate-added tanks (T<SUB>1</SUB>) while a pelleted diet was fed to the fish in the remaining three substrate-added tanks (T<SUB>2</SUB>) and the other three tanks without substrate (T<SUB>3</SUB>). Finding showed that both sexes started to reach maturity after 355 days. The average diameter of the ripened egg was 1.3-1.6 mm. Fecundity varied in different experimental groups in relation to fish weight and feeding. Compared to supplemental feed (T<SUB>3</SUB>) and in combination with sugarcane bagasse (T<SUB>2</SUB>), sugarcane bagasse alone group (T<SUB>1</SUB>) showed a positive relationship in all the parameters. These results showed that sugarcane bagasse can effectively be use as a substrate for the culture of the catfish <I>Heteropneustes fossilis</I>.
