Indoor industrial culture method for portunus trituberculatus

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 cultivation method of Portunus trituberculatus, in particular to an indoor industrialized cultivation method of Portunus trituberculatus. Background technique [0002] Portunus trituberculatus is an important seafood, loved by people. At present, the breeding methods of Portunus trituberculatus are mainly outdoor offshore enclosure, cage cultivation or pond cultivation. For example, the publication number is CN101790965A, and the name is "Artificial Breeding Method of Portunus trituberculatus", which discloses the construction of ponds, the control of water bodies for cultivation, and the cultivation of water bodies. Oxygenation methods, feed configuration and feeding, Z-shaped concealed mesh settings and other aspects of comprehensive technology can improve the survival rate of Portunus trituberculatus in ponds. At present, outdoor breeding is easily restricted by natural conditions, such as difficult water quality control,...

AI Technical Summary

Problems solved by technology

At present, outdoor breeding is easily restricted by natural conditions, such as difficult water quality control, many diseases, cannibalism, wind and wave damage, resulting in low survival rate, about 20-30%, low yield, and poor breeding efficiency
