Embodiment 1

[0017] Embodiment 1 A kind of artificial propagation method of stick flower fish, the steps are as follows:

[0018] (1) Breeding of broodstock: Select individuals at the age of 2 years and weighing about 15g as artificial breeding parents. After February every year, feed active feed and compound feed for intensive cultivation, and add vitamins; feed once a day, and run water to stimulate the development of broodstock, 1.5 hours / day, depending on the specific situation, the duration can be increased or decreased appropriately; Properly cultivate aquatic plants in broodstock ponds to transfer water, provide good shade and shelter, and increase dissolved oxygen in water. The method of distinguishing male and female broodstock is that the abdomen of female fish is swollen and soft, and the genital pores are large and prominent; the genital pores of male fish are slightly pink, and milky white semen flows out when the abdomen is lightly pressed.

[0019] When feeding, compound fe...

Embodiment 2

[0025] Embodiment 2 A kind of artificial propagation method of stick flower fish, the steps are as follows:

[0026] (1) Breeding of broodstock: Select individuals at the age of 2 years and weighing about 15g as artificial breeding parents. After February every year, feed active feed and compound feed for intensive cultivation, and add vitamins; feed twice a day, and run water to stimulate the development of broodstock, 2.5 hours / day, depending on the specific situation, the duration can be increased or decreased appropriately; Properly cultivate aquatic plants in broodstock ponds to transfer water, provide good shade and shelter, and increase dissolved oxygen in water. The method of distinguishing male and female broodstock is that the abdomen of female fish is swollen and soft, and the genital pores are large and prominent; the genital pores of male fish are slightly pink, and milky white semen flows out when the abdomen is lightly pressed.

Embodiment 3

[0033] Embodiment 3 A kind of artificial propagation method of stick flower fish, the steps are as follows:

[0034] (1) Breeding of broodstock: Select individuals at the age of 2 years and weighing about 15g as artificial breeding parents. After February every year, feed active feed and compound feed for intensive cultivation, and add vitamins; feed 1-2 times a day, and run water to stimulate the development of broodstock, 2 hours / day, depending on the specific situation, the duration can be increased or decreased appropriately; Properly cultivate aquatic plants in the broodstock pond in advance to transfer water, provide good shade and shelter, and increase the dissolved oxygen in the water. The method of distinguishing male and female broodstock is that the abdomen of female fish is swollen and soft, and the genital pores are large and prominent; the genital pores of male fish are slightly pink, and milky white semen flows out when the abdomen is lightly pressed.

Abstract

The invention relates to an artificial reproduction method of Abbottina rivularis and belongs to the technical field of artificial reproduction of fishes. Abbottina rivularis is artificially reproduced herein by parent fish rearing, artificial spawning inducement and hatching, egg laying, and artificial hatching and rearing. The method of the invention helps fill the technical blank of Abbottina rivularis in artificial reproduction, solve the problem that Abbottina rivularis cannot lay eggs naturally under artificial farming, and relieves the over-dependence of the Abbottina rivularis aquaculture on natural resources.

Description

technical field [0001] The invention relates to an artificial breeding method of stick flower fish, belonging to the technical field of artificial breeding fish. Background technique [0002] stick flower fish ( Rounded gudgeon ) Cyprinidae, Cyprinidae, Cyprinidae. Commonly known as tigerfish, Shahammer, and Hualibangzi, it is a small bottom-dwelling fish that is a specialty of my country, and is widely distributed in major water systems, lakes, ditches, and ponds across the country. With the improvement of human living standards, the stick flower fish has gradually become an object for people to watch and breed. In order to meet the market consumption demand, the artificial propagation technology of the stick flower fish also needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages, provide a method for artificial reproduction of the stick flower fish, solve the problem that the...
