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 (T1), 450/dec (T2), and 400/dec (T3) 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 (T1), 31.241.46 (T2), 31.361.29 (T3); dissolved oxygen (mg/l) 6.740.49 (T1),
6.970.63 (T2), 7.250.38 (T3); carbon dioxide (mg/l) 6.830.57 (T1), 6.360.68 (T2), 6.630.50 (T3) and
pH 7.070.22 (T1), 7.110.23 (T2), 7.460.08 (T3); transparency (cm) 40.190.23 (T1), 39.311.25 (T2),
40.831.34 (T3) respectively. The mean value of final fish weight (g) was 8.320.07 (T1), 9.560.10 (T2),
11.450.03 (T3). The specific growth rates (SGR) at 60 days were ranged from 4.6(T1) to 5.08(T3) in
different treatments during the experimental period. The survival rate ranged between 84 to 92%.
Treatment T2 and treatment T3 showed significantly higher survival than Treatment T1. The highest final
weight gain, survival rate and cost benefit ratio were found in T3 treatment. The production (kg/ha) of
Catla was 758.29kg (T1), 849.68kg (T2), 958.36kg (T3) respectively. The highest production was found in
T3. Among three treatments the production was very significant (p
