Wild eleotris oxycephala raising method

Abstract

The invention belongs to the technical field of aquatic animal breeding, and discloses a wild eleotris oxycephala raising method. The wild eleotris oxycephala raising method comprises the following steps: step one, selecting an earth pond or an indoor cement pond as a raising pond, and carrying out disinfection treatment; step two, catching and conveying wild eleotris oxycephala; step three, stocking the wild eleotris oxycephala in a grading manner, soaking the wild eleotris oxycephala in a potassium permanganate solution and then putting the wild eleotris oxycephala into the raising pond; step four, feeding with palatable feedstuff fishes and water earthworms in the earlier stage of raising, feeding with iced fresh trash fishes and compound feed in the middle and later periods, and carrying out water quality management; and step five, ending after raising for 1 to 2 months. The wild eleotris oxycephala culturing method has the beneficial effects that an artificial raising means is used for raising the wild eleotris oxycephala to obtain domestic eleotris oxycephala which can take artificial compound feed and can be artificially cultured; and the raising survival rate is high (above 80%); and the wild eleotris oxycephala raising method lays the foundation for artificial propagation research or cross breeding research of the eleotris oxycephala, meanwhile provides effective approaches and methods for raising and cultivation of other carnivorous wild fishes and has important significance.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, and relates to a method for domesticating wild fish, in particular to a method for domesticating wild snakehead snakehead. Background technique [0002] Eleotrisoxycephala belongs to the fishes of Perciformes, Gobioidei, Eleotridae and Eleotris. Bamboo shell and Heilinge are a kind of relatively rare freshwater small economic fish. In mainland China, it is mainly distributed in Shanghai, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi, Hainan, etc., and belongs to warm water fish. Channa cuspidatum is relatively small, with a weight of 15-50 grams per tail in the first year, and it is extremely rare for a body weighing more than 250 grams. However, the meat quality is good, and the market price is high. The size of 150 g per tail can reach 140 yuan / kg, and it is very popular among consumers. It is favored and has a great market prospect, and due to overfishing and river environmen...

Channa cuspidatum is relatively small, with a weight of 15-50 grams per tail in the first year, and it is extremely rare for a body weighing more than 250 grams. However, the meat quality is good, and the market price is high. The size of 150 g per tail can reach 140 yuan / kg, and it is very popular among consumers. It is favored and has a great market prospect, and due to overfishing and river environmental pollution, the wild resources of the rivers and rivers have been severely damaged and the resources have been exhausted. aspect research

In recent years, some operators have tried artificial breeding by catching wild channa, but the survival rate is extremely low.
