Abstract

An experimental study of the effect of various feed additives on the rate of mass accumulation, growth rate and survival of sterlet larvae was carried out. Four groups of fish were planted in flowthrough plastic pools with 150 fish each. The control group (I) was fed without additives, while the experimental group was fed with the addition of different preparations: II - preparation "AQUATAN" based on ellagotannins produced by the company "Tanin", Sevnica, Slovenia. Sevnica (Slovenia) at the rate of 2 g/kg of feed, III - antibacterial preparation based on ciprofloxacin "Antibak-100" (LLC "NVTs Agrovetzaschita"), at the rate of 0.5 g/kg live weight of fish, IV - probiotic based on Bacillus subtilis "SUB-PRO" (LLC "Vector-Euro") at the rate of 100 g/t feed. The preparations were added to the feed according to the instructions. The effect of preparations on fish was evaluated by fishery indicators: average daily growth rate, absolute growth, average daily gain and mass accumulation coefficient. During the experiment it was found that the values of fishery indicators in different groups of sterlet changed with different intensity depending on the time after the beginning of the experiment. The highest growth rate and mass accumulation rates were recorded in fish fed with SUB-PRO and Antibak-100, and the lowest with Aquatan. The results obtained indicate the expediency of further studies of the effect of various preparations on the fishery parameters of aquaculture objects aquaculture.
