High-yield feed for large water surface healthy aquaculture of aristichthys nobilis and production method of high-yield feed

Abstract

The invention relates to a high-yield feed for large water surface healthy aquaculture of aristichthys nobilis and a production method of the high-yield feed, wherein the high-yield feed is prepared by raw materials of 60-80 parts of bean cake, vegetable cake or cottonseed cake, 10-20 parts of wheat bran, 10-15 parts of wheat middling, 3-6 parts of shell powder, 10-20 parts of liquid lactobacillus, 20-40 parts of water and the like. The high-yield feed provided by the invention is transformed into animal protein from vegetable protein through bacterial fermentation, the vegetable protein with protein content being about 38% is transformed into animal protein with protein content being above 60%, and the high-yield feed is rich in nutrients and minerals and can be directly eaten by aristichthys nobilis without transformation in a water body so as to overcome the defect of transformation of nutrients and other substances in the water body through photosynthesis which restricts the growth and propagation of plankton; simultaneously, as the vegetable protein is transformed into the animal protein through the bacterial fermentation, the absorption and utilization rates of the high-yield feed for aristichthys nobilis are high; therefore, the high-yield feed solves the difficult problem of low aquaculture yield of the aristichthys nobilis due to shortage of food, and tests show that the yield can reach above 500kg / mu.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a high-yield feed for healthy aquaculture bighead carp in a large water surface and a production method thereof. Background technique [0002] Bighead carp is one of the main fishes in my country, accounting for about 18% of the freshwater fish production, and it is also one of the freshwater fish that the people of the country like to eat. The key technology of bighead carp farming is how to provide sufficient and palatable bait to ensure its rapid growth. Bighead carp feed on zooplankton, and the zooplankton in the water body must be obtained by transforming phytoplankton, bacteria or rot. Therefore, if bighead carp only rely on fertilization to increase production, it is very limited. Through more than 6 years of research, we have found that: first, the maximum output of artificial fertilization is within 100kg / mu; second, the animal protein content of artificial fee...

AI Technical Summary

Problems solved by technology

Through more than 6 years of research, we have found that: first, the maximum output of artificial fertilization is within 100kg / mu; second, the animal protein content of artificial feed must be as high as 50% or more, so that bighead carp can grow normally, while general feed Hello, the adult fish of bighead carp grow abnormally. The production cost of this kind of high-protein feed is as high as 7,000 yuan / ton, which is unacceptable to farmers

Therefore, there is no formal bighead carp feed
