Abstract/ Executive Summary:

In T₁, weight of GIFT increased from an initial weight of 5.50±1.2g to final weight of 96.00 g with an average of 90.00±15.4 g within 75 days. Growth rate ranged from 0.99 to 1.41 g/day. In T₂, B. gonionotus increased from an initial weight of 5.00±0.9 to final weight of 86.00g with an average of 81.00±12.7g. Net weight gain was 81.00±12.7g corresponding to growth rate of 0.91 to 1.25g/day. The GIFT increased from 5.50±1.2 to 83.50g with an average of 78.00±16.6g within the same period. Per day increment was 0.82 to 1.26g/day. In T₃, silver barb increased from 5.00±0.9 to90.00g with an average of 85.00±13.9g within 75 days. Growth rate ranged from 0.95 to 1.32g/day. From the results it is revealed that growth performance of GIFT was batter in monoculture than mixed culture system.

Keywords: BFRI GIFT, Silver barb, Culture technology

Location: Freshwater Sub-station, Jessore

Start Date: 01-07-2006

End Date: 30-06-2007

Program Area: Animal Health and Management

Commodity: Fish

Objectives:

To evaluat of the growth performance of BFRI GIFT and silver barb strains; refinement of BFRI GIFT and silver barb through multilocation trials; and estimation of cost-benefit analysis of GIFT and silver barb culture technology.

Methodology:

The experiment was conducted in 9 seasonal ponds of 10-20 decimal each for 5 months. There were three treatments and each treatment had three replications. Ponds were selected at three different sites of Jessore, viz. Patengali, Vekutia and Kholanda villages. Ponds were prepared according to standard protocol. Fingerlings of BFRI GIFT and silver barb were stocked @ 30,000/ha for monoculture in T₁_, T₂and T₃, respectively. In mixed culture system, GIFT and silver barb was stocked at the rate of 30,000/ha and the ratio of these two species was 1:1. Supplementary feed comprising rice bran 80% and mustard oilcake 20% was supplied @5% body weight daily. Monthly sampling was done by netting to monitor growth and health conditions. Feed requirement was adjusted at the same time.
