More Information
Summary:The invention belongs to the field of aquatic product breeding, and particularly relates to a method for increasing the survival rate of V-stage young crabs of river crabs. The method comprises the steps of constructing a culture pond, planting aquatic plants, culturing food organisms, selecting and stocking megalopa, culturing the V-stage young crabs, controlling water quality and preventing and controlling hostile organisms. According to the method, in the process that the V-stage young crabs are cultured, the high-quality megalopa is selected, a good ecological environment is constructed, an improved biological compost fermentation method is used, natural biological baits are cultured by using biological compost water, and artificial formula feeds and auxiliary materials with different protein proportions are fed at different stages, so that baits with good palatability and balanced nutrition are provided for the young crabs; in the process that the young crabs are cultured, benign dynamic balance of water
