Embodiment 2

[0024] It is basically the same as Example 1, except that four rows of horizontal shelves are longitudinally arranged on the bottom of the breeding pond.

Embodiment 3

[0026] It is basically the same as Example 1, the only difference is that five rows of horizontal shelves are longitudinally arranged on the bottom of the breeding pond.

[0027] The number of horizontal shelf rows is directly related to the width of the pool.

Abstract

The invention discloses an indoor industrial culture method for portunus trituberculatus, comprising the following steps of: building a culture bond, preparing culture baskets, shelving the culture baskets, stocking crab seedlings, managing culture and directionally mating. A horizontal shelf is arranged in the culture bond, a long-edge basket of the culture baskets is equipped with a slot in which a separation plate is inserted, a hiding room containing silt is arranged in the culture baskets on the left side and the right side of the separation plate, and male and female crab seedlings are independently cultured in the culture baskets on the left side and the right side of the separation plate; after growth shelling and reproduction shelling, the separation plate is taken off so that one male portunus trituberculatus and one female portunus trituberculatus naturally mate in the culture baskets, and after mating, the male portunus trituberculatus is moved out of the culture basket atonce. The indoor industrial culture method for the portunus trituberculatus has the advantages of easy control on water quality, high survival rate and good culture benefit, and can prevent the portunus trituberculatus from killing each other, and the portunus trituberculatus is not injured by wind damages and wave damages.

Description

technical field [0001] The invention relates to a method for cultivating swimming crabs three warts, in particular to an indoor industrialized method for cultivating swimming crabs three warts. Background technique [0002] Three wart swimming crab is an important seafood and is loved by people. At present, the cultivation methods of swimming crabs three warts are mainly outdoor offshore enclosure, cage or pond culture. For example, the public number is CN101790965A, and the name is "artificial culture method of swimming crabs three warts". The comprehensive technology of oxygenation method, feed configuration and feeding, Z-shaped concealed mesh setting and other aspects can improve the survival rate of swimming crabs in ponds. At present, outdoor aquaculture is easily restricted by natural conditions, such as difficult water quality control, many diseases, cannibalism, and damage caused by wind and wave disasters, resulting in a low survival rate of about 20-30%, low yiel...
