Fishery breeding platform for marine rapid batch fishing

The invention provides a fishery breeding platform for marine rapid batch fishing. The fishery breeding platform comprises a breeding net cage, a shell, an annular support, a cylindrical supporting block, a plurality of screening plates and a driving mechanism, wherein the supporting block is connected with the support through a supporting rod and is located at the center position of the support, the screening plates are fan-shaped, a plurality of screening holes used for screening fishes are formed in the screening plates, the two ends of each screening plate are coaxially pivoted to the support and the supporting block respectively, and the plurality of screening plates are distributed around the center of the supporting block at equal angles. During fishing, the screening plates are in a parallel state, fishes can be screened, the screening plates ascend to lift the fishes needing to be caught, when the screening plates need to sink to the bottom of the breeding net cage after harvesting, the multiple scre
