Popis: The article considers the effectiveness of complete feed with different levels of lysine and methionine for growing rainbow trout up to 10 g. The experiment aimed to establish the effect of different levels of amino acid nutrition of trout on its productivity. For this purpose, five experimental groups of this year were formed by the method of analogues. The experiment lasted 45 days and was divided into two periods: equalization (5 days) and main (40 days). During the equalization period, the experimental fish consumed feed of the control group. In the main period, the level of lysine and methionine in experimental feeds for different experimental groups of trout ranged from 2.8 to 3.2 % and from 0.90 to 1.10 %, respectively. As a result of research, it was found that the use of trout weighing up to 10 g of feed with high amino acid nutrition (3.1 % lysine, 1.05 % methionine) in the feeding of this year is accompanied by an increase in their weight by 9.2 % (p
