Method for cryopreservation of sperms from anoplopoma fimbria

Abstract

The invention discloses a method for cryopreservation of sperms from anoplopoma fimbria. The method comprises steps of acquisition of sperms, preparation of a culture medium, a cryopreservation process of the sperms and resuscitation and activation processes of the sperms, namely acquiring sperms from anoplopoma fimbria at sexual maturity by using an artificial anesthesia method; according to thesperm osmotic pressure of the anoplopoma fimbria, preparing a sperm culture medium; mixing the acquired sperms and the culture medium according to a volume ratio of 1:2, and further adding dimethyl sulfoxide which accounts for 10% of the volume of the mixed liquid so as to obtain a cryopreservation mixed liquid; and putting a uniformly mixed sperm cryopreservation mixed liquid sample into a refrigerator of 4 DEG C for 15 minutes, allowing the sample to stand for 5 minutes at the opening of a liquid nitrogen bottle, moving the sample downwards, further allowing the sample to stand for 5 minutesabove the liquid level of liquid nitrogen, further allowing the sample to stand for 5 minutes on the liquid level of the liquid nitrogen, and immersing the sample into the liquid nitrogen, and performing cryopreservation. By adopting the method disclosed by the invention, the anoplopoma fimbria sperm preservation operation can be convenient, efficient and effective, the anoplopoma fimbria spermscan be prevented from rapid deactivation or death in vitro, the preservation quality of the sperms can be improved, the preservation time can be prolonged, and the anoplopoma fimbria sperms can be available at any time in actual production.

Description

technical field [0001] The invention relates to the field of biological sperm preservation, in particular to a fish sperm preservation method. Background technique [0002] The scorpion belongs to the ray-finned fishes, the scorpionidae, the black scorpionidae, and the scorpion genus, and is distributed along the coast of the North Pacific Ocean. As a deep-water bottom-dwelling economic fish, the naked scorpion has a large body, white and tender meat, and rich nutrition, which has extremely high economic value. In fact there are reports of commercial exploitation of sablefish as early as 1800. At present, Russia, Japan, Canada and the United States all regard the sablefish as an important fishery resource, and gradually carry out research on its basic biology. According to reports, the body length of the adult Scorpionfish is 50-70 cm, and the life span can reach more than 100 years (the known maximum is 114 years old). Its rapid growth time is 5-7 years. At this time, abo...
