FIELD: fish industry. SUBSTANCE: method involves putting crawfish roe females into cage onto algae substrate enriched in live feed organisms; adding algae into substrate to maintain its initial layer height in the process of cultivating produced roes; arranging cages in basin in stages, with space between stages being 0.2 m. Size of each cage is 1.25x0.8x0.25 m and cover size is 1.0x0.525 m. Method allows at least 250 vigorous crawfish larvae per sq m to be produced. EFFECT: increased capacity, simplified method by eliminating crawfish feeding and usage of artificial feeds, reduced cost of planting material. 2 cl, 2 dwg, 1 tbl
