Abstract

The invention discloses a method for culturing soft blue crabs indoors. The method comprises the following steps of: constructing a culture pond; making culture baskets; arranging the culture baskets; stocking crabs to be cultured; managing the culture and collecting soft crabs. Horizontal shelves are arranged in the culture pond so that water and air in the culture baskets are favorably exchanged like in natural environment. Meanwhile, dirt in the culture baskets is lessened to benefit the growth of the blue crabs in the baskets and lessen diseases, the culture baskets are respectively provided with hidden chambers containing sediment to naturally accommodate the blue crabs, benefit the growth of the blue crabs, reduce the interference of outside on the growth of the blue crabs and improve the survival rate, and the blue crabs are cultured in respective culture baskets to avoid a phenomenon of mutual fighting among individuals and improve the survival rate in the culture process. Accordingly, the method for culturing soft blue crabs indoors has higher survival rate and good culture benefits.

Description

technical field [0001] The invention relates to a method for cultivating soft-shell crabs, in particular to a method for indoor cultivating soft-shell crabs of portunus trituberculatus. Background technique [0002] Portunus trituberculatus is an important seafood and is very popular among people, while soft-shell crabs are more popular because the whole crab is soft, the meat is fat and the whole crab is edible, and it is convenient to eat. The crab species currently cultivating soft-shell crabs include blue crabs, blue crabs, and portunus trituberculatus. For example, the publication number is CN101755679A, and the title is "Method for producing soft-shell crabs with Portunus trituberculatus", which discloses that 50-250 grams of Portunus trituberculatus that have not completed reproductive shelling are transported indoors and packed into a net cage with a cover In the process, the net cages are placed in the molting ponds for cultivation, and the cultivation includes ae...
