Efficient spawning induction method of misgurnus anguillicaudatus

Abstract

The invention discloses an efficient spawning induction method of misgurnus anguillicaudatus. The method comprises steps as follows: (1) selection of parents; (2) pretreatment of the parents; (3) agent injection; (4) collection of zygotes. Under the combined action of pretreatment of misgurnus anguillicaudatus and treatment with a spawning promotion stabilizer during mixed culture after hormone injection, the harm caused by human factors to the misgurnus anguillicaudatus is reduced, the anti-stress capacity of the misgurnus anguillicaudatus is improved, the yield, the quality and the breeding speed of zygotes are increased, and the method causes no harm to the misgurnus anguillicaudatus, human bodies and the environment, is environment-friendly and safe and has high popularization value.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for efficiently promoting the production of loach. Background technique [0002] Loach (Misgurnusanguillicaudatus), belonging to Cyprinidae, Loach family, is a kind of omnivorous small freshwater fish, which is very nutritious and known as "water ginseng". , The meat is tender, nutritious, and has good health care value, so it is favored by consumers at home and abroad. In addition to the increasing demand in the domestic market, loach is also a popular aquatic product in the international market, especially It is especially popular in Japan, South Korea and my country's Hong Kong, Macao and Taiwan regions. Affected by the supply and demand situation, at present, the price of loach in the market remains high and continues to rise. At present, the per mu benefit of artificial breeding of loach exceeds 10,000 yuan. Under the stimulation of high prices, artificial bree...

Problems solved by technology

The disadvantage of this method is that there is a lot of mucus on the surface of the loach, it is difficult to catch manually, it takes a long time, and it is easy to cause damage to the loach, so some people use ether, quinaldine, tribromoethanol, cocaine, tetracaine hydrochloride and other anesthetic drugs It is anesthetized in advance, but such drugs are mostly state-controlled products, and will have certain side effects on the human body and loach, which is inconvenient to promote; secondly, in the common polyculture ovulation and fertilization stage after the loach is injected with hormones, due to the mutual chasing and Excessive collisions can easily lead to a strong stress response in some parental loaches, resulting in a decrease in the number of fertilized eggs and the speed of fertilization, resulting in a large hidden loss
