Abstract: One of the important cultivable small indigenous fish which deserves immediate attention for commercial farming is the gulsha, Mystus cavasius. A preliminary study of growth and production performance of gulsha in a cage in the river Brahmaputra was carried out for a period of seven months during November 2012 to May 2013. Three treatments depending on the density of fish per cubic meter viz. 500, 600 and 700 were tested with the cage size of 3.0 m3. Fish were fed with pelleted supplementary feed (containing 30% crude protein) at the rate of 5-15% of body weight. In terms of growth and survival, relatively highest performance was found in the Treatment-1 compared to other treatments. The total production was found highest in the stocking density of the Treatment-1 (8.14 kg/m3) compared to other treatments. The total production of Treatments- 2 and 3 showed significant differences but there was no significant differences was observed in Treatment-1 and 2. However, total production in the Treatmen-1 showed highest production level, which could be applicable for the farmers reducing monetary investment for fingerling and feed purchase. Overall, cage with a size of 3.0 m3, stocking higher priced Gulsha at the rate of 500/m3 setting in the river during winter season could be a noble technology for the aquaculture farmer in Bangladesh.
