Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment: a kind of loach breeding method comprises the following steps:

[0014] 1) Seed selection: in March-October of each year, select the loach of 250-350g as kind of loach, wherein the proportioning of male loach and female loach is 1:6; Male loach and female loach are put into hatching bucket respectively;

[0015] 2) Oxygenation: 24 hours after the male loach and female loach were placed in the hatching bucket, they were injected with an oxytocin solution, which included 1 part of dioconone (DOM) for injection, 1 part of luteinizing hormone-releasing hormone A2 (LHRH-A2) for injection, 1 part of chorionic gonadotropin (HCG), 30 parts of glucose injection; each loach was injected with 0.4ml; after injection, the male and female loach were divided into standing tanks;

[0016] 3) Fertilization: 13-15 hours after the injection of oxytocin solution, squeeze the eggs for the female loach, and...

Abstract

The invention discloses a loach breeding method. The method comprises the following steps of (1) selecting seeds, (2) inducing spawning: injecting spawning induction liquid after male and female loaches are placed into a hatching barrel for 24 hours, (3) inseminating: squeezing eggs of the female loach and taking out a testis of the male loach after the spawning induction liquid is injected for 13 to 15 hours, adding gluecose solution to a testis mucous membrane and grinding for one minute, removing residual seminal vesicle, absorbing the seminal fluid into an injection tube, placing the female loach eggs to an egg container and injecting the seminal fluid, and pouring the germ cells to aerated mineral water and continuously stirring for two minutes, (4) hatching, and (5) spreading seedlings: 3 to 5 days later and during the temperature transition time of the morning and the night, converting the loach seedlings in a hatching pool to a seedling-spreading pool until the loaches seedlings grow 3 to 5cm. High loach fertility rate and high survival rate can be achieved by the use of the method.

Description

technical field [0001] The invention relates to a loach breeding method. Background technique [0002] Loach (Misgurnus anguillicaudatus) is a common small freshwater fish in my country. Its meat is tender, delicious, nutritious, and has high medicinal value. It is known as "water ginseng". In recent years, the market demand for loach has been increasing day by day. However, due to years of overfishing and the deterioration of the ecological environment in natural waters, the resources of wild loach in my country are facing the danger of depletion. Since the 1990s, the breeding and aquaculture industry of loach has been gradually developed in my country, and it has become an important aquatic economic fish in our country. As a new small economic fish in our country, loach has broad development prospects. Therefore, the genetic breeding research of loach has important economic significance. However, in the prior art, the fertilization rate and survival rate of loach breedi...
