Mixed feed dried fish powder for Channa argus and preparation method thereof

Abstract

The invention provides a mixed feed dried fish powder for Channa argus and a preparation method thereof; the feed dried dish powder is mainly prepared from, by weight, 5-10 parts of fresh Decapterus maruadsi, 5-10 parts of fresh Trachurus japonicus, 5-10 parts of fresh Traccatichthys pulcher, 5-10 parts of fresh silver carp, 0.5-2.5 parts of soybean oil, 0.5-1 parts of lard, 2-4 parts of yam rhizome powder, 0.3-1.2 parts of a fermentation assistant, 0.5-0.8 part of microbial protease acid, 0.1-0.2 part of edible salt and 0.02-0.06 part of vitamin complex; the fresh Decapterus maruadsi, fresh Trachurus japonicus, fresh Traccatichthys pulcher and fresh silver carp are used as main materials, the parts of fresh fish bodies are classified for extracting protein, lysine and fish collagen protein to prepare dried fish powder with balanced nutrition, and the problem that live fish or frozen dead fish easily causes infection and result in low nutrition absorption in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of aquaculture bait fish, in particular to a dried mixed bait fish powder of black fish and a preparation method thereof. Background technique [0002] Snakehead is a common name for snakehead, also known as mullet, raw fish, fortune fish, snake fish, firehead fish, etc. Snakefish is ferocious in nature, strong in fecundity, and has a huge appetite.

Problems solved by technology

[0004] At present, as long as the culture mode of snakeheaded fish is mainly artificial breeding, feed is used. There are two types of snakeheaded feed. One is the frozen bait fish feed based on small wild fish. After the treated bait fish is often eaten by snakehead, snakehead is prone to disease and bacterial infection, resulting in low resistance, easy bleeding in the mouth of snakehead, frequent hyperemia and inflammation of the epidermis, and high death rate; the second is artificial compound feed , There are buoyant granular materials, hard granular materials and powdery batch materials. Many problems will also occur in the breeding process of snakeheaded fish, but if the ingredients are not scientific, snakeheaded fish will grow slowly, small in size and light in weight, which will seriously hinder the cultivation of snakeheaded fish. artificial large-scale farming

[0005] At present, there are many kinds of bait fish for snakeheaded fish, but most of them are fed with live fish or frozen dead fish, which are susceptible to infection and have low nutrient absorption, which is very unfavorable to the growth of snakeheaded fish
