Taming method of wild hucho bleekeri living bodies

Abstract

The invention provides a taming method of wild hucho bleekeri living bodies. The method comprises the steps of manufacturing a taming fishpond containing an oxygen increasing mouth, throwing schizothorax taliensis wild adults to conduct taming, and conducting feeding with cold water fishes or schizothorax taliensis offspring seeds and with an artificial nutrition feed additive, and comprises the specific steps of adopting local stones to build the taming fishpond of 4 m in length, 2 m in width and 1.5 m in depth, wherein the inner wall of the fishpond is troweled with cement, stored water is 0.8-1.2 m, and the fishpond is provided with a main water source, a subsidiary water source and an oxygen increasing head; putting the rescued hucho bleekeri wild living bodies into the taming fishpond, and throwing the schizothorax taliensis wild adults; conducting feeding with the cold water fishes or the schizothorax taliensis offspring seeds according to weights of the hucho bleekeri wild living bodies, and conducting feeding with the artificial nutrition feed additives containing glycine betaine, citric acid, sodium chloride, inosinic acid and complex microbial flora. The taming method of the wild hucho bleekeri living bodies has the advantages of being mild, relieving the stress reaction of the wild hucho bleekeri living bodies, maintaining the natural ferity of the wild hucho bleekeri living bodies, shortening the artificial taming transient time, and improving the taming rate of survival of the wild hucho bleekeri living bodies.

Description

technical field [0001] The invention belongs to the technical field of salmon aquaculture, and in particular relates to a domestication method for living wild Sichuan-Shaanxi salmon. Background technique [0002] Salmonidae belongs to Salmoniformes, Salmonidae, and Salmonidae. It is the largest and most endangered species in the family Salmonidae. Its meat is tender, delicious, fast-growing, and large in size. It is one of the few Large-scale freshwater fish that can grow to hundreds of catties can be called the "Siberian tiger" in the water and have important economic value. However, in recent decades, the resources of jellyfish have been seriously damaged, and it has become very rare. It is listed as an endangered species in my country, and the endangered level is increasing year by year. Therefore, it is necessary to improve the domestication survival rate of wild Sichuan-Shaanxi salmon after rescue. [0003] Currently rescued live wild Sichuan-Shanxi salmon are sent to...

AI Technical Summary

Problems solved by technology

[0003] Currently rescued live wild Sichuan-Shanxi salmon are sent to fish ponds temporarily storing oxygen. The facilities are in poor condition and there is no oxygenation or aeration equipment. Such or small cold-water fish directly cause the stress response of wild Sichuan-Shaanxi salmon to be strong, swim quickly, and do not open their mouths to eat fish. Usually, blood oozes on the body surface and the rear edge of the gill cover after 3-5 days. After that, there will be water mold, slow swimming, weak breathing, etc., and the long-term survival rate is extremely low

Chinese patent CN103907551B discloses a kind of method for inducing juvenile salmon to open mouth and domestication and Chinese patent CN 101218902B discloses a kind of method for artificial cultivation and domestication of salmon fry, all of which are aimed at the artificial cultivation of juvenile salmon and fry. Breeding methods. At present, the artificial domestication and breeding of juvenile and seedlings of Zheluo salmon have been relatively successful, but there are few studies on the domestication survival rate of wild Sichuan-Shaanxi Zheluo salmon after rescue. There are few studies on the domestication of live Shanzhe salmon
