Abstract: The research work was conducted for 60 days in earthen ponds of Fisheries Department under the University of Rajshahi to investigate fingerling production of riverine Catla,
Catla catla (Hamilton, 1822) in pond habitat. The experiment was carried out under 3 treatments each with 3 replications. The stocked fries (
Catla catla) were collected from Padma River, Rajshahi. The stocking density was maintained at 500/dec (T
1), 450/dec (T
2), and 400/dec (T
3) respectively. Fishes were fed same diet in three different treatments consisting of Fish meal (20%), rice bran (25%), wheat bran (25%) and mustard oil cake (30%) at the rate of 4-8% of body weight. The Physico-chemical characteristics of pond water were measured fortnightly. The mean values of some water quality parameters such as temperature (°C) were 31.30±1.29 (T
1), 31.24±1.46 (T
2), 31.36±1.29 (T
3); dissolved oxygen (mg/l) 6.74±0.49 (T
1), 6.97±0.63 (T
2), 7.25±0.38 (T
3); carbon dioxide (mg/l) 6.83±0.57 (T
1), 6.36±0.68 (T
2), 6.63±0.50 (T
3Â) and pH 7.07±0.22 (T
1), 7.11±0.23 (T
2), 7.46±0.08 (T
3); transparency (cm) 40.19±0.23 (T
1), 39.31±1.25 (T
2), 40.83±1.34 (T
3) respectively. The mean value of final fish weight (g) was 8.32±0.07 (T
1), 9.56±0.10 (T
2), 11.45±0.03 (T
3Â). The specific growth rates (SGR) at 60 days were ranged from 4.6(T
1) to 5.08(T
3) in different treatments during the experimental period. The survival rate ranged between 84 to 92%. Treatment T
2 and treatment T
3 showed significantly higher survival than Treatment T
1. The highest final weight gain, survival rate and cost benefit ratio were found in T
3 treatment. The production (kg/ha) of Catla was 758.29kg (T
1), 849.68kg (T
2), 958.36kg (T
3) respectively. The highest production was found in T
3. Among three treatments the production was very significant (
p<0.05). The cost benefit ratio was for (T
1) 1:1.79, for (T
2) 1:1.88 and for (T
3) 1:2.19 respectively. The results of the present study indicate that treatment T
3 is better than treatment T
1 and T
