Problems solved by technology

This method has not considered the problem that the female parent eats her own fish eggs in the running water hatching, so the hatching rate needs to be improved, and the problem of inconsistent maturation of the wheat ear fish has not been considered at the same time

Embodiment 1

[0016] Such as figure 1 Shown, the wheat ear fish artificial large-scale breeding method comprises the steps:

[0017] (1) Parent selection: choose healthy, disease-free and non-injured 2nd-year-old fish as parents, and carry out separate breeding of male and female parents;

[0018] (2) Preparation of oxytocin feed: add oxytocin substances to the conventional feed, that is, add 0.05 mg of LRH-A and 1 mg of DOM to the conventional feed of the male parent and the female parent at a rate of 0.05 mg per kilogram of conventional feed; Add 30g of Angelica sinensis, 10g of fennel, and 100g of black soybeans to the feed per kilogram of conventional feed; add 100g of oats, 100g of soybeans, 60g of shrimp skin, 10g of polygala, 25g of epimedium, and 15g of cornel to the male parent’s feed. , so as to produce special-purpose oxytocin feed for the female parent and the male parent;

[0019] (3) Parents’ separate induction treatment: start 1 month before breeding and laying eggs, feed t...

Embodiment 2

[0022] The artificial large-scale propagation method of wheat ear fish comprises the steps:

[0023] (1) Parent selection: choose healthy, disease-free and non-injured 2nd-year-old fish as parents, and carry out separate breeding of male and female parents;

[0024] (2) Production of oxytocin feed: add oxytocin substances to the conventional feed, that is, add 0.15 mg of LRH-A and 5 mg of DOM to the conventional feed of the male parent and the female parent at a rate of 5 mg per kilogram of conventional feed; Add 15g of Angelica sinensis, 5g of fennel, and 50g of black soybeans per kilogram of conventional feed in the feed; add 50g of oats, 50g of soybeans, 30g of shrimp skin, 5g of polygala, 15g of epimedium, and 10g of cornel in the feed of male parents. , so as to produce special-purpose oxytocin feed for the female parent and the male parent;

[0025] (3) Parents’ separate induction treatment: start 1 month before breeding and laying eggs, feed the parents with the induct...

Abstract

The invention discloses an artificial large-scale breeding method of pseudorasbora parva. The method comprises the steps of parent selection, manufacturing of spawning induction feed, separate spawning induction of parents, insemination, incubation and the like. By means of the artificial large-scale breeding method of pseudorasbora parva, artificial breeding of pseudorasbora parva can be achieved; through the design of a specially-made spawning pond, it can be effectively guaranteed that the parents do not eat roes, and the survival rate is increased by around 2 times compared with that of the prior art; meanwhile, through the treatment of hormones before spawning induction, the gonads of the parents can be synchronously mature, and centralized insemination is achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificial large-scale propagation of wheat ear fish. Background technique [0002] Wheat ear fish is an important economic fish in my country. It is commonly found in rivers, lakes, ponds and other water bodies. It lives in shallow water and is omnivorous. The wheat ear fish has tender meat, delicious taste, few intermuscular thorns, high protein and calcium content, especially for the elderly, children and pregnant women. The survival rate of wheat ear fish in nature is low. The main reason is that mature wheat ear fish generally like to lay their eggs on aquatic plants, and the female parent will eat its own eggs; insemination. [0003] CN2013106178677 discloses a method for artificial reproduction of octopus, which includes the steps of broodstock selection, broodstock cultivation, daily management, induced labor, artificial insemination, hatching and the l...
