Embodiment 1

[0034] A kind of domestication method of adult wild catfish, comprising the steps of:

[0035] 1) Collection of species fish

[0036] Put the collected species of fish in the holding pond, inject broad-spectrum antibacterial drugs to prevent inflammation and infection, inject once every 3 days, 2-3 times in a row, enter the domestication pond for feeding after the body surface is normal;

[0037] 2) Fish domestication

[0038] Anesthetize the breeding fish with an anesthetic, pour the chopped natural bait into its stomach with a soft plastic dropper, once a week, continue to feed the live fish during this period, and stop the dropper when it is observed that the black-spotted catfish can actively prey Feeding, domesticated species of fish are fed live fish once every 3-4 days; intramuscular injection of broad-spectrum antimicrobials is given to species of fish every half a month.

Embodiment 2

[0040] This embodiment is on the basis of embodiment 1:

[0041] The anesthetic is MS-222, and the anesthetic dose is 0.08g / L.

Embodiment 3

[0043] This embodiment is on the basis of embodiment 1:

[0044] The anesthetic is MS-222, and the anesthetic dose is 0.2g / L.

[0045] The water temperature in the domestication pool is 8°C, the water body maintains a salinity of 5‰, the concentration of ammonia nitrogen in the water body is 0.4 mg / L, the concentration of nitrite is 0.05 mg / L, and the pH is 7-8; the water surface is 0.5 m away from the top of the pool.

Abstract

The invention provides a domestication method for adult wild glyptosternum maculatum regan. The adult wild glyptosternum maculatum regan is domesticated pertinently according to characteristics of thewild glyptosternum maculatum regan. The domestication method comprises the following steps: 1) putting collected brood fishes in a temporary breeding pond, injecting a broad-spectrum antibiotic to prevent inflammation and infection once every three days for 2-3 times continuously, and feeding the fishes into a domestication pond after the body surfaces are normal; 2) anesthetizing the brook fishes with an anesthetic, filling stomachs of the brook fishes with shredded natural bait through a soft plastic dropper one every week, continuously feeding living fishes in the period, finishing dropperfeeding when the glyptosternum maculatum regan can predate actively, and feeding the domesticated brook fishes with living fishes once every 3-4 days; and carrying out intramuscular injection of thebroad-spectrum antibiotic on the brook fishes once. The domestication method is high in operability and good in practical applicability, and can be used for achieving scaled and standardized domestication of the adult wild glyptosternum maculatum regan.

Description

technical field [0001] The invention belongs to the technical field of fish cultivation, and in particular relates to a domestication method of adult wild catfish. Background technique [0002] Glyptosternum maculatum (Glyptosternum maculatum) is only distributed in the Yarlung Zangbo River system in China. It belongs to Siluriformes (Siluriformes), Sisoridae (Sisoridae), and Glyptosternum (Glyptosternum). It is the only one of the three known species of Glyptosternum. The species distributed in China occupies an important position in the research on the phylogeny of the fishes in China. Black-spotted catfish has delicious taste, delicate meat, and good taste. It can also be used as medicine in Tibetan medicine. It has both edible and medicinal value, and its selling price is increasing year by year. The current market price can reach 1700-2600 yuan / Kg, and its economic value is relatively considerable. . In recent years, due to the impact of human activities on its living...
