Abstract

This study was aimed to evaluate the efficiency of three protein level feeds on the fingerlings production of riverine endangered Notopteruschitala (Hamilton, 1882) for a period of two months in ponds. Chital fry (Initial wt, 5.6±0.19 g) were randomly stocked at the rate of 7410 per hector. Feeding trials were conducted under 3 treatments (T1: feed contains 35% protein, T2: feed contains 30% protein, T3: feed contains 25 % protein) each with 3 replications. No significant (P<0.05) difference was observed for all the water quality parameters among the treatments. A suitable range of water quality parameters (temperature, water transparency (cm)), dissolved oxygen (mg/l), pH, alkalinity (mg/l), ammonia) were recorded with the environment of experimental ponds. The treatment had significant effects on weight gain, ADG, SGR among treatments. Highest weight gain (19.31 ± 0.23 g) was observed in T1, lowest (13.96 ± 0.15 g) in T3. SGR (1.65±0.02) and ADG (0.18±0.005) were significantly (P<0.05) highest in T1 followed by T2 and T3. The N chitala exhibited highest survival rate (96.66%) in T1 than T2 followed by T3 (88.89 %). The best FCR value (3.02±0.09) was recorded in treatment T1 with 35% protein contain feed. Relatively, highest benefits (138690±175.36 BDT/ha) were found from treatment T1 compared to other treatments. Similarly, the cost benefit ratio was highest in T1 (1:1.23) and lowest in T3 (0.95). Findings indicated that treatment T1 (35% protein containing feed) was found best in terms of growth, production and economics of N. chital for fingerling production in ponds.
