abstract
An experiment was conducted to evaluate the effects of different feeds viz., tubifex (T₁), chicken intestine paste (T₂) and tilapia fish paste (T₃) on the growth and survival of taki, (Channa punctatus) in nine trays. A total of 300 larvae /m² (average weight 28.70±0.50 mg) was reared for 21 days in each treatment having three replications. The net weight gain of the larvae in T₁ (122.30±1.24 mg) was significantly higher (P<0.05) than those of T₂ (113.18±1.042 mg) and T₃ (104.58±1.30 mg). The percent length gain, percent weight gain, SGR and survival rate were also significantly (P<0.05) higher in T₁ (345.90±2.91, 426.14±4.33, 7.91±0.04 and 74.00±1.00) than that in T₂ (334.91±1.72, 394.34±3.63, 7.61±0.03 and 37.67±1.53) and T₃ (323.61±2.82, 364.39±4.55, 7.31±0.05 and 34.33±0.58). Considering the present findings, live feed tubifex could be accepted as the best diet for mass seed rearing of C. punctatus in hatcheries. Water quality parameters were within the suitable range and there was no significant (P<0.05) variation among the treatments.
