| Abstract | ||||
| Trials were undertaken with first-feeding com- mon carp Cyprinus carpio larvae after hatching to determine the effect of dietary soy bean oil as co-6 source and/or phospholipid (PL) with two levels (2 and 4%),on the average growth performance and survival rate in series of two periods (about 30-day cach) located in Fish Research Station be- longing to National Institute of Oceanography and Fisheries. Low morality % was occurred with lev- el of 4% PL in the first period, and with level of 2% oil in the second period. The average growth performance were improved with diet contained 2% PL in the first period and with diet contained 2% soy bean oil and PL together (50: 50%) in the second period. Concerning, body fatty acid com- position, (FA’s), the high values of saturated FA were occurred in fish received 4% oil while, the Higher values of unsaturated and @-6 FA’s were obtained with diet contained 2% PL.The present study clearly confirmed that addition of phospholipid to the diet was important to ob- tain good survival of first-feeding common carp larvae up to 4% dietary level. In the other old stage of larvae the uptake and desertification of fatty acid occurred without addition of more phos- pholipid to the diet that may be due to a sufficient quantity of phospholipid of endogenous origin for micelle formation in the intestinal lumen. | ||||
