Fish sperm preserving fluid and preserving method

Abstract

The invention discloses a fish sperm preserving fluid which is prepared from 2.120-2.420g of NaCl, 1.602-2.202g of KCL, 0.178-0.478g of CaCl2, 0.133-0.333g of MgSO4.7H2O, 0.114-0.414g of NaHCO3, 0.128-0.328g of VC and 500mL of distilled water. The fish sperm preserving method comprises the following steps of: (a) sperm collection: wiping and drying the genital pore region of a mature milter by using a towel, slightly pressing the abdomen of the mature milter, and collecting the extruded sperm by using a suction tube; and (b) sperm preservation: putting the collected sperm into a clean container, adding the sperm preserving fluid of which the volume is 10-20 times of the volume of the sperm, and preserving in low-temperature light-tight places.

Description

technical field [0001] The invention relates to a fish sperm preservation solution and a preservation method, belonging to the technical field of animal reproduction. Background technique [0002] my country is a country rich in aquatic species resources, and the rich and diverse aquatic species resources have played a very important role in the development of my country's aquaculture industry. The subfamily of scorpionidae is a small fish that lives in the middle and lower layers of water bodies. It is distributed in most of the rivers and their affiliated water bodies in the plains of my country. Although the artificial reproduction technology of many fishes has been broken through, the artificial reproduction of fishes in the subfamily of scorpionidae has not yet been realized. Due to the long-term overfishing of fishery resources and the pollution of the water environment, the fish resources of the subfamily of Scorpidae have seriously declined and are on the verge of e...
