Three feeds were used in three treatments where Treatment-T<sub>1</sub>with pellet feed (control), Treatment-T<sub>2</sub> with tubificid powder and Treatment-T<sub>3</sub> having live tubificid worms. Twenty fingerlings (8.04 ± 0.01 g) were released in each 50 L tank for 45 days rearing. The fishes were fed twice a day at 10% of body weight for first 15 days and that of 8% per day for the next 30 days. Sampling was conducted fortnightly. Significant higher mean weight 48.53 ± 1.13 g was observed in stinging catfish at the 45th day fed with live tubificid worms than those of others (P&lt;0.05). The highest survival rate was 83.33±4.41%, average daily gain 0.90 ± 0.03 g day<sup>-1</sup>, specific growth rate 3.99 ± 0.05%, food conversion ratio 1.65 ± 0.10 and protein content 17.48 ± 0.28% were found at the 45th day of treatment T3 when live tubificid worms were used as feed. Live tubificid worms can be used as a good alternative to commercial feed in rearing of stinging catfish.</p><p>Bangladesh J. Sci. Ind. Res. 51(3), 175-182, 2016</p> ER -
