Embodiment Construction

[0006] First use quicklime or bleach or potassium permanganate and other disinfectants to clean the pond, and then put it into clear water. The water depth is 0.8 meters. At this time, put more than 14,000 fish fry into the pond respectively. ℃, fry feeding time is twice a day, and the feeds are as follows: feed egg yolk or rotifers one month ago, then feed egg yolk, soybean milk and mixed feed, and feed mixed feed after 5 months. 5 egg yolks each time, 0.5 kg of soybean milk per day, ground soybeans into slurry, 1 kg of mixed feed each time in the early stage, and increase as the fish grows as appropriate. Among them, the egg yolk needs to be wrapped with double layers of gauze and kneaded repeatedly to make a slurry, and then sprinkled all over the pond. The mixed feed is fed according to the conventional "four fixed" method. Now domesticated with the above method There are more than 10,000 white fish, reaching the standard of commercial fish.

Abstract

A method for artificial naturalizing Anabarilius grahami in pond includes disinfecting pond, filling clean water at 8-25 deg.C in it until water depth is 0.8 m, raising fry of Anabarilius grahami by feeding egg yolk or rotifer, laterly feeding egg yolk, soybean milk and mixed feed, and finally feeding mixed feed at different growth stages, and growing in deep water (40-50 m). Its advantages are high survival rate and low cost.

Description

[0001] Artificial pond domestication method of white fish Technical field: [0002] The present invention relates to a kind of The invention discloses a method for artificially domesticating whitefish in ponds, belonging to the technical field of fish product cultivation. Background technique: [0003] A unique fish that grows in Fuxian Lake in Yunnan—— White fish is one of the four famous fish in Yunnan. For hundreds of years, local people have caught it for food, creating a unique human-fish culture. Before the 80s White fish has always been the main economic fish in Fuxian Lake and the pillar industry of the people along the lake. After the 1980s, due to the immersion of exotic fish and overfishing, the Whitefish populations have plummeted. now on the brink of extinction. Restoration Whitefish resources have become an important research content in Yunnan Province. The present invention aims to carry out Pond domestication studies of whitefish. Through li...
