Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:

[0030] A method for selecting species of white prawns resistant to hypoxia, comprising the steps of:

[0031] 1) Select 200 living adult shrimps; select adult shrimps with robust body, no defect in appendages, no trauma, active movement, and a single shrimp body weight of 2-2.5 grams as the adult shrimps; the water body needs to be removed from the water Predators and algae. To ensure that the death factor of adult shrimp is only low oxygen, so as to ensure the directionality of screening;

[0032] 2) Construct a water body with a dissolved oxygen content of 4ppm, the water body is isolated from the atmosphere, and the adult shrimp is placed in the water body; the water body needs to remove harmful organisms and algae in the water. To ensure that the death factor of adult shrimp is only low oxygen, thereby ensuring the directionality of scree...

Abstract

The invention relates to a method for selecting hypoxia-tolerant Exopalaemon carinicauda. The method includes: selecting live adult Exopalaemon carinicauda; preparing water with the dissolved oxygen content being not lower than 4ppm, and placing the adult Exopalaemon carinicauda into the water, wherein the water is isolated from atmosphere; when dead Exopalaemon carinicauda appears in the water along with dissolved oxygen content lowering, removing the dead Exopalaemon carinicauda from the water to prevent the water from being polluted by the decomposed dead Exopalaemon carinicauda; when the number of the live adult Exopalaemon carinicauda lowers to 10% of the initial adding quantity of the adult Exopalaemon carinicauda, collecting the live adult Exopalaemon carinicauda in the water. By the method, the adult Exopalaemon carinicauda individuals good in hypoxia tolerance can be screened out to facilitate follow-up breeding.

Description

technical field [0001] The invention relates to the technical field of white prawn cultivation, in particular to a method for selecting species of white prawns resistant to hypoxia. Background technique [0002] The existing white prawns have poor resistance to hypoxia. In large-scale farming operations involving multiple steps such as breeding and selection, white prawns often die in large areas due to lack of oxygen, which limits their large-scale farming. . Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provides a method for selecting species of white prawns resistant to hypoxia, which is specifically realized by the following technical solutions: [0004] A method for selecting species of white prawns resistant to hypoxia, comprising the steps of: [0005] 1) Choose live adult shrimp; [0006] 2) Construct a water body with a dissolved oxygen content of not less than 4ppm, the water bod...
