Abstract
Thinlip mullet fry grew heavier when fed on the 25% - 30% crude protein diets (6.6-7.4 gm /fingerling). The 18% - crude protein treatment produced slightly lower harvest weight (5.9 gm /fingerling) compared to those of higher protein diets at lower feeding costs. The 18% - crude protein diet was an appropriate substitute for the 30 % - crude protein diet in terms of economic efficiency. However, the 30% - crude Protein diet superseded all other treatments in terms of condition factor and growth performance (P<0.05). When searching for alternative sources for nutrition of thinlip mullet fry during secondary rearing, the results indicated that best daily weight gain and economic efficiency were obtained when feeding thinlip mullet fry with 18% - crude protein diet, followed by the use of 25% - crud protein diet, when compared to the use of 30% - crude protein diet. The present results showed that the use of ground corn for mullet fry nutrition in green water tanks resulted in significant reduction in weight gain by 50% (p<0.05) with slight reduction in condition factor
