Abstract

The invention relates to a method of culturing Erythroculter ilishaeformis fish fries of large specifications. The method comprises the following steps: stocking the fish fries of Erythroculter ilishaeformis adult fishes in the water area which is relatively small and easily controlled with the reasonable density; providing rich water, stress management, and the feeding of fish meals; controlling the water environment and the disease occurrences in the culturing process; and obtaining the Erythroculter ilishaeformis fish fries with the average weight of each one being above 50g after 120-150 days of culture, and the specification being 15-18cm. Compared with the other inorganic and organic water fertilizing methods, the invention adopts the fertilizing method of using the zymotechnics of multiplicity of microbe groups, so as to reduce the pollution to the feeding environment of the pond by fertilizer water and achieve the purpose of emission reduction. In addition, the content of various beneficial bacterium groups in the pond is increased through the fertilizing method of using the zymotechnics of multiplicity of microbe groups, thus being favorable to the culturing of food organisms, thereby decreasing the number of pathogens, and reducing the occurrence of various diseases.

Description

technical field [0001] The invention relates to a method for cultivating large-scale seedlings of red catfish, which belongs to the technical field of aquaculture. Background technique [0002] Red carp with cocked mouth is commonly known as big white fish, cocked mouth, cocked shell, white silk, Xingkai big white fish, cocked carp, stinging fish, cocked white, white fish, pouting carp, etc. The Guangdong area is commonly known as the Yangtze River Heshun, the middle reaches of the Yangtze River are commonly known as Qiaobai and Baiyu, and the lower reaches of the Yangtze River are commonly known as Taihu Lake Whitefish. The scientific name is Erythroculter ilishaeformis. It is one of the famous "Three Whites of Taihu Lake", with tender meat. Every June, the carp is fat and strong, rich in nutrition, which happens to be the season for planting seedlings. The reputation of "Cream" has been passed down from generation to generation along the coast of Taihu Lake, and it is re...
