Acipenser schrenckii sperm cryopreservation solution and preservation method

Abstract

The invention provides an acipenser schrenckii sperm cryopreservation solution and a preservation method. The cryopreservation solution is prepared from the following components in parts by weight: 1-5 parts of sodium chloride, 1-5 parts of potassium chloride, 5-10 parts of ethylene glycol, 3-10 parts of sodium dihydrogen phosphate, 0.5-2 part of pyridoxine, 0.1-1 part of GSH, 0.01-1 part of HA, 0.1-1 part of SDS and 0.5-2 part of Vc. According to the acipenser schrenckii sperm cryopreservation liquid, damage of freezing to sperm cell structures and genetic materials is reduced, and the survival rate and fertilization rate of frozen sperms are increased.

Description

technical field [0001] The invention belongs to the field of sturgeon breeding, and in particular relates to a sperm cryopreservation solution and a preservation method of sturgeon. Background technique [0002] Sturgeon's sturgeon belongs to Osteophytes, Atenopterygia, Sclerophyta, and Sturgeoniformes. It is mainly distributed in the Amur River (Heilongjiang, China) basin. Because of its advantages such as fast growth, strong disease resistance, and high economic value, it has been It has become a popular cultured species in China, accounting for 50% of China's total sturgeon production, and there is still an increasing trend. However, due to extensive breeding techniques and high breeding density, the frequency of disease outbreaks has increased, which has greatly hindered the healthy and sustainable development of sturgeon aquaculture. In recent years, scientific researchers have done a lot of work in the protection of Acipenser schneidi resources, artificial breeding, a...
