Rearing of the larvae of Bunni (Barbus sharpeyi) on live under laboratory condition.


Indoor rearing of newly hatched Bunni larvae Barbus sharpeyi was carried out at the Marine Science Center in April 2005. Larvae were reared under controlled condition. These larvae fed on three food types, live food: the Rotifer Brachionus calyciflorus, the brine shrimp Artemia franciscana, the Cladocera Moina affinis, and artificial food NRD. The results showed that rearing of larvae during 28 days gave high growth rate and survival rate of fish larvae fed on live food compared with those fed on artificial feed. The average of length and weight of fish larvae fed on B. calyciflorus were 41.9 mm /larvae and 113.5 mg /larvae, respectively, whereas the average of lengths and weights of larvae fed on A. franciscana were 37.7mm / larvae and 110.2 mg / larvae, respectively, and those fed on M. affinis were 33.5 mm / larvae and 94.6 mg / larvae in terms of length and weight, respectively. The average length and weight result from artificial food NRD, were 28.4 mm / larvae and 83.6 mg / larvae, respectively. The survival rate was higher on rotifer treatment (82.5 %), whereas lower values were recorded (75.9, 74.6 and 62.4 %) for A. franciscana, M. affinis and NRD, respectively.
