Abstract

The invention relates to the technical field of river crab culture, and discloses a micro-running-water net cage culture method of juvenile crabs for large-scale river crab culture. The micro-running-water net cage culture method comprises the following steps: 1, the juvenile crabs are put into a culture device; 2, water is continuously introduced into the culture device, so that the water in theculture device keeps flowing; 3, daily scientific culture management is conducted on the juvenile crabs in the culture device; and 4, after the juvenile crabs are cultivated and formed, the juvenile crabs are taken out of the culture device to be stocked. The micro-running-water net cage culture method of the juvenile crabs for large-scale river crab culture is simple and convenient to operate, the labor intensity of workers is effectively reduced, deposited sludge can be prevented from influencing the water quality of water in a water tank, and the safety of juvenile crab culture is effectively improved.

Description

technical field [0001] The invention relates to the technical field of river crab culture, in particular to a method for cultivating crab seedlings in a large-scale river crab culture in a micro-flow cage. Background technique [0002] River crabs are arthropods belonging to the mitten crab family Crabidae. River crabs often live in caves on the mud banks of rivers, rivers, and lakes, and are active at night. River crabs feed on fish, shrimp, animal carcasses and grains, and often migrate to the estuaries where they go out to sea to lay eggs every autumn. River crab is a widely cultivated aquatic product with high economic value. [0003] When the existing river crab micro-flow net cage cultivation method is cultivating, after the crab seedlings are cultivated, the net cages need to be manually taken out one by one to take seedlings. Because a large number of crab seedlings have been cultivated in the net cages, the weight of the net cages is relatively high. Large, there...
