Embodiment 1

[0038] 1. Screening of fast-growing hybrid parents:

[0039] 1.1. Screening of female parents:

[0040] From mid-April to the end of November, 2010, wild yellow catfish from lakes around the Yangtze River Basin (such as Liangzi Lake, Hong Lake, Dongting Lake and Poyang Lake) were collected, and healthy wild females weighing more than 100g were selected. The yellow catfish is used as the initial yellow catfish female parent; the robust wild male yellow catfish with no injury on the body surface and a body weight of more than 250g is selected as the initial yellow catfish male parent, and the initial yellow catfish female parent and the initial yellow catfish male parent are selected After harvesting, under the conditions of artificial breeding, after domestication and ingestion of artificial compound feed, the initial parental breeding of yellow catfish was carried out. From May to July 2011, the gonad development degree of the initial parent fish of yellow catfish was observed...

Embodiment 2

[0068] 1. Screening of fast-growing hybrid parents:

[0069] 1.1. Screening of female parents:

[0070] From the end of September to the end of November 2012, wild yellow catfish from lakes around the Yangtze River Basin (such as Liangzi Lake, Hong Lake, Dongting Lake and Poyang Lake) were collected, and healthy wild female yellow catfish weighing more than 100 cm were selected. The yellow catfish is used as the initial yellow catfish female parent; the healthy wild male yellow catfish with a body surface of 250g or more is selected as the initial yellow catfish male parent, and the initial yellow catfish female parent and the initial yellow catfish male parent are selected well. Finally, under the condition of artificial breeding, the initial yellow catfish parents were cultivated after being able to eat artificial compound feed after domestication. From May to July 2013, the gonad development degree of the initial yellow catfish broodstock was observed, and mature yellow cat...

Embodiment 3

[0097] 1. Screening of fast-growing hybrid parents:

[0098] 1.1. Screening of female parents:

[0099]From the end of April to the end of November 2013, wild yellow catfish from lakes around the Yangtze River Basin (such as Liangzi Lake, Hong Lake, Dongting Lake and Poyang Lake) were collected, and healthy wild female yellow catfish weighing more than 100g were selected. The yellow catfish is used as the initial yellow catfish female parent; the healthy wild male yellow catfish with a body surface of 250g or more is selected as the initial yellow catfish male parent, and the initial yellow catfish female parent and the initial yellow catfish male parent are selected well. Finally, under the condition of artificial breeding, after domestication and ingestion of artificial compound feed, the initial parental breeding of yellow catfish was carried out. From May to July 2014, the gonad development degree of the initial parent fish of yellow catfish was observed, and mature yellow...

Abstract

The invention provides a cross breeding method for a Pelteobagrus fulvidraco variety namely Huangyou No. 1 with improved growth character. The cross breeding method comprises the following steps: 1, selection of rapidly-growing cross parents: 1.1, selection of a female parent, and 1.2, selection of a male parent; 2, strengthening breeding of parents; 3, artificial parturition hastening; 4, artificial cross fertilization; 5, artificial incubation; and 6, fry breeding. The cross breeding method provided by the invention breeds the first-filial generation of Huangyou No. 1 by cross breeding of female Pelteobagrus fulvidraco and pelteobagrus vachelli; and the first-filial generation of Huangyou No. 1 is tawny in body color, and has extremely significant growth vigor and strong stress resistance.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for hybrid breeding of Huangyou No. 1 yellow catfish with improved growth characteristics, which is a method for producing fast-growing yellow catfish using interspecies hybrid breeding technology, parental screening and innovative breeding technology. Huangyou No. 1, a new species of yellow catfish with the advantages of stress resistance and disease resistance. Background technique [0002] Pelteobagrus fulvidraco (Richardson) belongs to Sliuriformes, Bagridae, and Pelteobagrus. Pelteobagrus vachehi (Richardson) belongs to Sliuriformes, Bagridae, and Pelteobagrus, and its common names are Langsi, Huanglading, Jiangyan and so on. Pelteobagrus fulvidraco and Pelteobagrus vachehi belong to the same genus. They are widely distributed in the Yangtze River system and are important small demersal economic fishes in my country. Peeled catfish is suitable for ...
