The study of feeding parameters of Beluga (Huso huso) larvae fed with Artemia nauplii and Daphnia
Beluga (Huso huso) larvae with average body weight of 30.43 ± 1.25 mg and density of 2 fish per liter having three replicates (100 fish per tank) were fed on the 30 percentage of body weight in a day during 15 days using Daphnia magna, Artemia urmiana nauplii and mix of Artemia and Daphnia magna, Ar...

| description | Beluga (Huso huso) larvae with average body weight of 30.43 ± 1.25 mg and density of 2 fish per liter having three replicates (100 fish per tank) were fed on the 30 percentage of body weight in a day during 15 days using Daphnia magna, Artemia urmiana nauplii and mix of Artemia and Daphnia magna, Artemia urmiana nauplii and the mix of them (Daphnia 50% w/w and Artemia 50% w/w) in a completely randomized design. The fish was weighed individually at the start and the end of the experiment. The carcass proximate compositions of samples of fish were determined. The maximum of carcass crude protein (76.70%) and lipid (8.83%) was obtained in treatments of Artemia and showed significantly difference with treatment of Daphnia and mix of Artemia and Daphnia, respectively (P<0.05). Thesignificant difference in protein, lipid and energy productive value were observed among the treatments (P<0.05). The highest energy retained as protein (13.76 J/day) and lipid (45.14 J/day) were observed in treatment of Daphnia. The best final body weight (193.98) and feed conversion ratio of 2.80 were observed in treatment of Daphnia. The maximum specific growth rate in protein (SGRP), lipid (SGRl) and energy (SGRe) were obtained in fish that fed on Daphnia. The results of this experiment showed that the potential of Huso huso larvae in using of Daphnia magna, Artemia urmiana nauplii and mixture of them was different and Daphnia had a suitable effect on promotion of feeding parameters in larval stage. |
