Abstract

This study was carried out on the effect of cyclopoid copepod Acanthocyclops trajani on beluga Larvae (Huso huso) first feeding in March 2018. The applied diets contained: the composition of Artemia naupli and Daphnia magna (A diet) and the composition of Artemia naupli, Daphnia magna and A. trajani (B diet). Different methods were used to prepare live feeds and the analysis of the fatty acids of live feeds and beluga larval tissues was performed according to the instruction. The results of this study indicated that the lenghth, body weight and specific growth rate average in larvae of A and Bdiets were not significantly different. In spite of the fact that A. trajani was significantly different in amount of n-3 fatty acids in comparison to Artemia naupli and D. magnabut indicated more effectivity in survival rates (80%) of beluga larvae with these latter live feeds compound, as a supplement. Furthermore, the B diet was significantlydifferent in essential fatty acid DHA, in comparison to A diet, So, with due attention to important effects of this fatty acid on stress resistance of larvae, the better results withthe view to survival rate in this treat will be explainable.This study indicated thatfreshwater copepod was potential supplemental live food, specifically to increasenutritional value and survival rate of valuable fish larvae as beluga.
