Abstract

A rearing trial was carried out to determine the effects of dietary SOYBEAN LECITHIN on GROWTH performance, feed conversation and body composition of Persian Sturgeon, ACIPENSER PERSICUS fingerlings, reared under culture conditions in Iran. The experimental period was planned as 60 days period in the International Sturgeon Research Institute. Four semi-purified diets were formulated to contain increasing percentages of commercial SOYBEAN LECITHIN (0, 1, 2 and 3%). 240 A.persicus fingerlings with an average weight of 1.9±0.1 g and an average total length of 7.0±0.3 cm were randomly allocated to 15 L of water (20 fish per tank) in 12 tanks. During the feeding trial the fish were fed daily to apparent satiation. The final weight and final total length in the fish fed diets supplemented with 1 and 3% of lecithin and without lecithin were significantly higher than diet supplemented with 2% of lecithin (p<0.05). Comparison of results obtained from condition factor revealed that there is a significant difference among fish fed diet 2% of lecithin and those fed 1 and 3% of lecithin and also control group. Survival rates in the fish fed diet supplemented with 3% of lecithin (%88.8±1.9) were statistically better than diet 1% of lecithin (% 73.3±11.5) (p<0.05). The highest specific GROWTH rate (SGR) was recorded in fish fed diet supplemented with 1% of lecithin although no significant differences (P>0.05) were detected as compared with diets 3% of lecithin and control diet. The results obtained from carcass analysis reveal that values of the saturated fatty acids in A.persicus carcass decreased with increase in lecithin in diets.
