Embodiment 1

[0028] (1) Broodstock selection: select 2-3 age mature yellow catfish broodstock, the weight of female broodstock is controlled at 100-200g, the weight of male broodstock is controlled at 220-350g, and the ratio of male to female is 4:1;

[0029] (2) Artificial induced labor:

[0030] The oxytocin drugs are mixed injections of chorionic gonadotropin HCG, luteinizing hormone releasing hormone analog LRH-A2, and dioconone maleate DOM. Gonadotropin HCG1500IU / kg, luteinizing hormone releasing hormone analogue LRH-A2 16μg / kg, the injection dose of male broodstock is half of that of female broodstock;

[0031] The injection site is at the base of the pectoral fin, the depth of the injection needle is 3cm, and the injection direction is 45 degrees to the ventral surface of the body axis;

[0032] Select yellow catfish in the early stage of reproduction and individuals with poor sexual maturity, and use two injections, the interval between the two injections is 14 hours, and the inje...

Embodiment 2

[0037] (1) Broodstock selection: select 2-3 age mature yellow catfish broodstock, the weight of female broodstock is controlled at 150-180g, the weight of male broodstock is controlled at 160-300g, and the ratio of male to female is 4:1;

[0038] (2) Artificial induced labor:

[0039] The oxytocin drugs are mixed injections of chorionic gonadotropin HCG, luteinizing hormone releasing hormone analog LRH-A2, and dioconone maleate DOM. Gonadotropin HCG1500IU / kg, luteinizing hormone releasing hormone analogue LRH-A2 16μg / kg, the injection dose of male broodstock is half of that of female broodstock;

[0040] The injection site is at the base of the pectoral fin, the depth of the injection needle is 3cm, and the injection direction is 45 degrees to the ventral surface of the body axis;

[0041] Select yellow catfish late in reproduction and individuals with good sexual maturity to be injected with one needle, but male fish are injected 5-6 hours later than female fish;

Abstract

The invention discloses an artificial breeding method for pelteobagrus fulvidraco. The artificial breeding method has the advantages that well-developed pelteobagrus fulvidraco fries can be acquired,the method is simple and convenient to operate, parent fish utilization rate is high, mass production of the pelteobagrus fulvidraco can be realized, and the method has great significance in mass breeding of the pelteobagrus fulvidraco.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an artificial breeding method for yellow catfish. Background technique [0002] The yellow catfish belongs to the genus of the catfish of the family Siluriformes and is an important economic fish in the rivers and lakes of China. Because of its excellent characteristics and delicious meat, the artificial breeding of the yellow catfish has been widely accepted. Pay attention to. [0003] The artificial breeding of yellow catfish is the most important link in the artificial breeding process. Compared with natural breeding, it can overcome the shortcomings of low efficiency and low fry survival rate in the natural breeding process. Contents of the invention [0004] The object of the present invention is to provide a method for artificial breeding of yellow catfish with a high success rate aiming at the shortcomings of artificial breeding of yellow catfish. [0005] To achieve the abo...
