Abstract: Feeding and reproductive biology of Blue perch, Badis badis, were studied for domestication and captive maturation under captivity. For captive maturations semi-natural habitat for fish were made with the help of sandy bottom, gravels, stones along with plantation of some of the ornamental plants and were stocked in 02 different systems i.e., flow through system (75 cm length × 45 cm width × 25 cm water height; 85 lit approx) and Cement cistern (180 cm length × 95 cm width × 45 cm water height; 770 lit approx). A total number of about 464 specimens of B. badis belonging to the size ranges of 16.5-59.3 mm and 0.05-2.52 g were taken for this present study. The RLG value was found increased with the increase of total body length. The average GaSI was found to be 4.76±1.27. Sexual dimorphism is well marked by their colour pattern, adult males display bright colour with 5 pairs (10 nos.) of black stripes visible on the body.
