Special feed for ictalurus punetaus and high-yield and high-efficiency culture model thereof

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a special feed for ictalurus punetaus and a high-yield and high-efficiency culture model thereof. The special feed for the ictalurus punetaus has the advantages that the ictalurus punetaus can digest and absorb the feed well; the growth speed of the ictalurus punetaus is increased; the feed coefficient is reduced; the stability of the feed in water is high; aquaculture water quality is not prone to pollute; feed nutrition is balanced; a liver-protecting and gallbladder-protecting additive is added, so that the health of the ictalurus punetaus is protected, the survival rate and digestibility are increased, and the growth speed is high; and after eating the feed, the ictalurus punetaus has a stable body color and has no yellow-flesh risk; and the high-yield and high-efficiency culture model has the advantages that diseases are reduced; diseases can be effectively controlled through low-density culture; the death rate can be reduced; with the use of animal protection products such as a substrate improver and a disinfection product, the diseases are reduced; two batches of ictalurus punetaus are harvested in one year, the yield and efficiency are increased, the culture period is shortened, and the fund pressure of a culturist is relieved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and specifically relates to a special feed for channel catfish and a high-yield and high-efficiency breeding mode thereof. Background technique [0002] Channel catfish, also known as channel catfish, belong to the Siluriformes and Catfish family. Channel catfish are native to the North American continent, from southern Canada to northern Mexico, and are one of the main freshwater cultured species in the United States. [0003] South China is a key breeding area for channel catfish in the country. The quality of channel catfish feed is uneven. Feed companies follow suit and do not design a reasonable formula according to the nutritional needs of channel catfish. [0004] In addition, as the channel catfish breeding area increases year by year, the breeding density increases year by year, and the blind pursuit of production, channel catfish breeding does not have a reasonable breeding model t...

Problems solved by technology

[0003] South China is a key breeding area for channel catfish in the country. The quality of channel catfish feed is uneven. Feed companies follow suit and do not design a reasonable formula according to the nutritional needs of channel catfish.

[0004] In addition, as the channel catfish breeding area increases year by year, the breeding density increases year by year, and the blind pursuit of production, the channel catfish breeding does not have a reasonable breeding model to match, the breeding risk is high, the disease occurs frequently, the breeding management is difficult, and the profit level is low, which seriously restricts Development of Channel Catfish Aquaculture Industry
