Breeding method capable of increasing survival rate of green crabs

Abstract

The invention provides a breeding method capable of increasing the survival rate of green crabs. The method specifically comprises the steps that a cube-shaped breeding box provided with inner box bodies and an outer box body is selected, the inner box bodies are placed in the single outer box body, and the inner box bodies are arranged in a single layer; the inner box bodies are placed in the outer box body and fixed at the bottom of the outer box body, the outer box body is placed on a sea beach, and a fixing rod is inserted into the beach to fix the outer box body so that the outer box bodycan move up and down on the fixing rod along with rising tide and ebb tide; a box cover of each inner box body is opened, a young green crab is placed in each inner box body, the box covers are fixed, 1-10 green crabs are placed in the outer box body, the green crabs are captured when the weight reaches 300-800 g, the outer box body is moved out, the box covers of the inner box bodies are opened,and the green crabs can be captured and packaged. By means of the breeding method, fighting of the green crabs is avoided, and the survival rate is greatly increased; according to the breeding method, management is convenient, saves the breeding cost and improves benefits.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a breeding method for improving the survival rate of mud crabs. Background technique [0002] Scylla serrata, commonly known as blue crabs and red sturgeons, are distributed in southern China, Japan, India, Africa and other tropical and subtropical harbors and coastal mangrove swamps. In my country, they are mainly produced in Zhejiang, Fujian, Taiwan, and Guangdong south of the Yangtze River estuary. And along the coast of Guangxi, Scylla serrata has delicious meat, unique flavor, rich nutrition, and can also be used as medicine. It is a famous edible crab with high economic value and a great demand in domestic and foreign markets. , is the main cultured species cultivated in the south coast of my country. With the maturation of breeding technology, the income from breeding mud crabs has become the main source of income for the coastal farming industry. At presen...

Problems solved by technology

The above-mentioned three breeding methods adopt the feed feeding method, which changes the living habits of the blue crabs, and the food they prey on changes accordingly, which naturally affects the growth of the blue crabs, as well as the protein composition and content of the meat, and the taste is also affected. impact, the freshness of blue crab meat will be greatly reduced, which is the inherent deficiency of the above three farming methods
