Embodiment 1

[0018] The method for Portunus trituberculatus described in the present embodiment to temporarily raise and overwintering survival rate is implemented in Rizhao Kaihang Aquaculture Company of Shandong Province, specifically comprising the following steps:

[0019] A method for improving the survival rate of Portunus trituberculatus for temporary breeding and overwintering comprises the following steps: selecting the best and decontaminating, removing the attack power of moving limbs, disinfecting for temporary breeding and overwintering.

[0020] 1. Selection and decontamination In the middle and late September of 2012, artificially cultured portunus trituberculatus with bright color, strong vitality, strong physique, complete appendages, standard body shape and a weight of more than 300g were selected from outdoor breeding ponds. Each tail crab is cleaned and disinfected. The disinfection method is to immerse the crabs in a dipping bath of 500ml / L concentration Aipule disinfe...

Abstract

The invention discloses a method for improving temporary culture and wintering survival rate of portunus trituberculatus and belongs to the field of aquaculture techniques. The method comprises the steps of selecting high-quality portunus trituberculatus to wash, removing attach force of rock dynamic limbs, disinfecting, performing temporary culture and wintering; the step of removing the attach force of rock dynamic limbs adopts the technical solution of achieving the same technical effect by removing the rock dynamic limbs. According to the method, the rock dynamic limbs of the portunus trituberculatus are removed, so that the portunus trituberculatus loses the capability of clamping and attacking, the fight and harm between the portunus trituberculatuses can be reduced; after removing the dynamic limbs, the temporary culture and wintering survival rate of portunus trituberculatus is greatly improved; the temporary culture and wintering density is improved by more than two times; the utilization rate of facilities is improved; the cost can be reduced; and the income can be increased.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for improving the survival rate of Portunus trituberculatus for temporary breeding and overwintering. Background technique [0002] Portunus trituberculatus is a high-quality and high-grade aquatic product with abundant offshore resources and high economic value. The market demand is huge. The fishing output of Portunus trituberculatus in my country is 350,000 tons. Artificial breeding began in the late 1980s. In recent years, the breeding industry of Portunus trituberculatus in my country has developed rapidly, with an artificial breeding area of ​​500,000 mu and an annual output of 100,000 tons. Portunus trituberculatus is a large aquatic product species in the coastal areas of my country. No matter the wild resources caught or the harvested products of artificial breeding, in order to prolong the market delivery period and balance the market, they need to go through tempora...
