The article assesses the biotechnological potential of crickets of Acheta domesticus species for use as feed for aquaculture. The optimal diet was selected and the most favorable conditions for the reproduction of insects in a mini-farm were determined. Studied the qualitative composition of the substrate on the basis of the crickets of the species Acheta domesticus. With the aim of selecting the optimal technological modes of processing of raw materials on the basis of the insects investigated the total antioxidant activity of aqueous extracts of dried crickets of the species Acheta domesticus crustaceans of the genus Gammarus pulex. For crickets Acheta domesticus activity was 1.508 g routine per 100 g absolutely dry sample and 1.888 g routine for Gammarus pulex. It was found that the samples of Gammarus pulex have the property of thermal stability according to the criterion of total antioxidant activity during drying of dry samples to a constant weight at 105°C.
