| Summary: | ow nloaded from ( p 0.02), with SG and LG exhibiting values of 1.3 and 1.08, respectively. Regression analysis of body weight gain over time between the two grades revealed a significantly higher proportional weight gain in SG ( p 0.01). Cost analysis revealed an initial saving of 8.5 % by selecting SG juveniles. This saving was reduced to 2.9 % when the cost of feed-ing these fish was taken into account. However, food wastage was higher in this study than would be expected in a commercial operation, suggesting that the actual saving for the on-grower could be greater than 2.9%. Selecting smaller sized juveniles for transfer will in-crease the growout period. However, this may be offset by the fact they may be transferred earlier, at a significantly lower price. |
