Breeding method of hybrid pelteobagrus fulvidraco

Abstract

Disclosed is a breeding method of hybrid pelteobagrus fulvidraco. The method comprises the steps that parent fishes are selected, wherein pelteobagrus intermedius is selected as female parents, and pelteobagrus vachelli at the age of 5 years old or above is selected as male parents; two pituitrin injections are given to pelteobagrus intermedius artificially at an interval T; then, pelteobagrus intermedius is cultured, after pelteobagrus intermedius is raised up and mature, roes are pushed out and collected artificially, then semen of pelteobagrus vachelli is added to the collected roes, and artificial insemination operation is conducted to obtain fertilized eggs; then, the fertilized eggs are poured into a basin, and muddy water is utilized to conduct membrane-removing operation on the fertilized eggs; after the membrane-removing operation is completed, the fertilized eggs are poured to a filter screen and filtered and cleaned with clear water; the fertilized eggs after filtering and cleaning are put into a hatching tank for hatching, wherein the hatching tank is filled with clear water; hybrid pelteobagrus fulvidraco fry are obtained after standing is conducted for a hatching time J in the hatching tank. Through the adoption of the breeding method of hybrid pelteobagrus fulvidraco, obtained hybrid pelteobagrus fulvidraco is higher in growth speed, fresh and smooth in meat, and high in immunity and disease resistance.

Description

technical field [0001] The invention relates to a breeding method of hybrid yellow-bone fish. Background technique [0002] Pelteobagrus fulvidraco, also known as yellow-bone fish, scientific name: Pelteobagrus fulvidraco, is a fish belonging to the genus Pelteobagrus fulvidraco. Yellow bone fish can benefit the spleen and stomach, diuresis and swelling. It is mentioned in "Yi Lin Ji Yao": to treat water and gas edema, that is, to mix yellow catfish with mung beans and garlic, boil them in water, remove the fish and eat beans, and take the sweat to adjust the sage root. Both attack and supplement are used, especially suitable for those with spleen deficiency and severe swelling. The taste of yellow-bone fish fed with artificial concentrated feed is worse than that of naturally grown yellow-bone fish, the meat quality is looser, and the umami taste is reduced; while the growth cycle of yellow-bone fish fed with pure green feed is longer, which cannot meet the market demand....

AI Technical Summary

Problems solved by technology

The taste of yellow-bone fish fed with artificial concentrated feed is worse than that of natural-grown yellow-bone fish, the meat quality is looser, and the umami taste is reduced; while the growth cycle of yellow-bone fish fed with pure green feed is longer, which cannot meet the needs of the market

When the yellow-bone fish is raised in monoculture, the species is single, the pond space and feed are not fully utilized, and the benefit is low

The types of yellow-bone fish include: Washii yellow-bone fish, fork-tailed yellow-bone fish, Antang yellow-bone fish, middle yellow-bone fish, thin yellow-bone fish, Jiang yellow-bone fish and glossy yellow-bone fish, etc., purebred yellow-bone fish Fish are more demanding on the environment, grow slower, and are less resistant to disease
