In this study, the morpho-biological characteristics of the Daphnia magna Straus culture and microalgae of the genera Ankistrodesmus, Botryococcus, Scenedesmus, Chlorococcum and Chlorella were studied. Protein and fat storage of micronutrients was determined. It has also been found that when Daphnia magna cultures are propagated on the basis of micronutrients, their growth rate and biomass production. The results showed that the average growth rate of daphnia on the basis of strains of the genus Chlorella was 1.33%, on the strains of the genus Chlorococcum - 0.74%, 55.5% higher than the chlorella strains 43.1% higher than the strains of the genus Scenedesmus. This is due to the fact that the cells of the Chlorella strain are thicker and more difficult to break down than other species. The protein and fat storage of the Daphnia magna Straus culture grown on the basis of micronutrients has been studied. According to the results obtained, Daphnia magna Straus, fed on the basis of representatives of the Ankistrodesmus generation from microalgae relative to the control, recorded 28.67% protein and 3.9% fat. The Scenedesmus genus has 29.07% protein, 4.03% fat, Botryococcus 31.36% protein, 4.12% fat, Chlorella 28.60% protein, 3.64% fat, Chlorococcum 34.10% protein and 3, 84% fat retention was found. Daphnia species based on Chlorococcum and Botryococcus microalgae have been recommended for breeding and use as a source in feeding small fish fry.
