Popis: The introduction of high-protein feed from crustacean processing products in the form of flour into the composition of the rainbow trout compound feed has a positive effect on the growth of fish live weight, reduces feed costs, does not change the biochemical composition of the blood, changes the chemical composition of muscle tissue, improves the amino acid rate in the 1st experimental group. Due to the relatively low cost in comparison with fish meal, the use of crayfish meal makes the cost of compound feed cheaper and increases the economic effect of growing rainbow trout.
