Efficiency of the additive "Abiopeptid with iodine" in feeding of a Lena sturgeon growth in recirculating aquaculture system
The article presents information to study the influence of high doses of iodine organic form on the Lena sturgeon productivity when grown in recirculating aquaculture system. «Abiopeptid with iodine» was used as a biologically active supplement. The content of iodine in chelate form was 100, 200 and 500 mcg/ml. The result of the experiment is a direct correlation between the amount of iodine in food and weight gain. Thus, the greatest weight gain was observed after «Abiopeptid with iodine» application with the iodine amount 200 mcg/ml per 1 kg of fish weight. It increases Lena sturgeon productivity by 9,3% and fish livability by 3,33 %, and profitability by 10,16% in comparison with the control group.
