| Summary: | In this paper, a new type of fertilizer/feed for Uzbekistan were developed when growing fry to underyearlings. In four experimental nursery ponds (1-3 ha each) with brackish water (2.5 - 3.9‰), cultured carp fish were grown in a pond polyculture using mineral fertilizers and wheat bran soaked in soy milk. In different variants, the total fish productivity was 27 - 48.9 q/ha, underyearlings of all species reached an average weight of more than 100 g, the yield was 76-88%, provided that they were stocked with 5-10 gram fry in early July. Juveniles of cyprinids can be successfully reared in brackish water fed from a collector-drainage system in Uzbekistan. |
