One of the most important functions of humic substances is a stimulation and activation of physiological and biochemical processes in living organisms. Channel catfish (Ictalurus punctatus) — one of the main objects of commodity production in different countries, the value of the fish is a high rate of growth and the ability to adapt to growing conditions. This led to the selection the object of studies. As a result of studies we found dietary impact of feed additives humate, sodium humate potassium Vitaton drug on fertility and growth of different age groups of channel catfish (Ictalurus punctatus). The use of biologically active substances contributes to the preservation of larvae channel catfish at 16–25%. Feeding larvae feed with biologically active agents increases their growth rate and increased average daily gain at 26–63%. The maximum effect of the use of drugs is observed in the second half pidroschuvannya. Under the same dose of preparations using humate potassium in their composition was proved to be the most effective.
