specific Embodiment approach 1

[0006] The specific embodiment one: present embodiment is a kind of cultivation method of Rockwell larva seed, specifically completes according to the following steps:

[0007] 1. Artificial oxytocin: First, select healthy and healthy female and male Rodgers as broodstock, inject oxytocin drugs at the base of the dorsal fin of the broodstock, and then culture them in running water at a temperature of 14°C~16°C for 3~5 days, and the process is complete. Artificial induction of labor; 2, fertilization: according to the ratio of female and male Rodgers (5 to 7): 3, the male Rodgers semen is collected and placed in a beaker, and the female Rodgers eggs are collected and placed in the spawning basin. Then pour the collected male chrysalis semen into the spawning basin to carry out artificial insemination with the female chrysalis roe, that is, to complete fertilization and obtain fertilized eggs; 3. Hatching: first, spread 16~24 mesh on the bottom of the hatching tank Then sprinkle...

specific Embodiment approach 2

[0014] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the healthy and healthy female and male Rodger's carp selected in step 1 are specifically carried out as parent fish by the following operations: 1. Selection of female Rochester broodstock: select fish weighing more than 80g, free from injury and disease, and over 2 years old; 2. Selection of male Rochester broodstock: select fish weighing more than 60g, free from injury and disease, and over 2 years old. Others are the same as the first embodiment.

[0015] Discrimination of female Rodgers: During the breeding season, the belly of the female fish is soft and swollen in the shape of a round sac, the anus and genital pores are larger, and the reddish protrusion is smaller.

[0016] The identification of male chrysalis: During the breeding season, the male fish has a smaller abdomen and a darker body color. The genital pores are not red and swollen, but the genitals protruding...

specific Embodiment approach 3

[0017] Specific embodiment three: the difference between this embodiment and one of the specific embodiments one or two is: the injection of oxytocic drugs at the base of the dorsal fin of the parent fish described in step one is specifically carried out as follows: injecting the oxytonic drug at the base of the dorsal fin of the parent fish , the injection depth is 4.5mm~5.5mm, after the injection, use 75% alcohol to smear the outside of the fish body for disinfection; the injection dose of the broodstock is: inject 1000UI of chorionic gonadotropin per kg of the broodstock Hormone, 10 μg of salmon gonadotropin-releasing hormone analogue and 2 mg of dioconone; the dosage of the injection of broodstock of Androgenus chinensis is: inject 600 UI of chorionic gonadotropin and 6 μg of salmon gonadotropin per kilogram of broodstock of Androschus chinensis Hormone-releasing hormone analogs and 1 mg of dioconone. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a fish fry breeding method, in particular relates to a phoxinus lagowskii fry breeding method, and aims at solving the problem of having no Phoxinus lagowskii fry breeding method currently. The method comprises the steps of artificial spawning, fertilization, incubation, and fish fry breeding. The method has the advantages of being simple and convenient to operate, low in cost, good in bred fry quality, filling up the blank of the phoxinus lagowskii fry breeding technology in China, realizing the preparation, incubation and full-labor fry breeding of the wild phoxinus lagowskii fertilized eggs, effectively solving the problems that the semen and roes can not be collected simultaneously in the phoxinus lagowskii fry development process, and the fertilized eggs can not be prepared, and realizing the labor incubation and fry breeding of the fertilized eggs for the first time. The method is mainly used for breeding phoxinus lagowskii fry.

Description

technical field [0001] The invention relates to a method for cultivating fry. Background technique [0002] Phoxinus lagowskii Dybowskii belongs to Cypriniformes Cypriniformes in fish taxonomy, Cyprinidae Cyprinidae, Leuciscinae subfamily Leuciscinae, and Phoxinus Agassiz. Liugen Pond. It is a small economic fish that grows wild in rivers and rivers. Under natural conditions, it is mainly distributed in northern Xinjiang and the Heilongjiang River Basin. The body of this fish is long, slightly flattened, and spindle-shaped. There are inconspicuous black stripes from the middle to the caudal peduncle, and the abdomen and side of the body are silvery yellow or silvery white. The fish is omnivorous. Under natural conditions, it feeds on aquatic plants, algae and aquatic insects. Its survival water temperature is not high, and it can live in cold waters or warm waters. The fish has the advantages of delicious meat, tender meat, fewer intermuscular spines, and high protein and...
