FIELD: industrial fishing. SUBSTANCE: chlorella paste is added to cultural medium as a nutrient substrate (concentration is 1.0-1.5 mln cells/ml) and, additionally, blood (0.2 ml/l) for every 3 days of cultivation. Cultivation is carried out for 10 days at 20± 2 C. Biomass yield of crayfish is increased up to 1020-1220 g/m3. Mean productivity of culture is 99-118 g/m3 per 24 h. EFFECT: improved method of cultivation, enhanced yield of biomass.
