Problems solved by technology

Although fish need various nutrients in the growth process, the nutrients in fish feed also need to be balanced with each other. Excessive protein not only cannot be fully utilized by fish, but will also be excreted in the form of nitrogen, polluting water quality
The fish feed in the prior art is usually combined by directly adding various nutrients, and the raw materials rich in various nutrients are combined by mixing. Although the obtained fish feed is rich in various nutrients, it is , fish do not absorb well
In addition, the fish feed in the prior art also has the problem of high cost
[0003] The patent application number is CN201810660908.3, and the patent application title is "a fish feed", which discloses a fish feed made of corn, multivitamins, soybean protein powder, fish adhesives, earthworm powder and theaflavin. The obtained fish feed is safe to eat, but the protein in it exists in the form of natural polymers, which cannot be fully absorbed and utilized by fish

Abstract

The invention provides pollution-free freshwater fish feed. According to the pollution-free freshwater fish feed, biological waste is converted into nutrient substances for fishes, sugarcane filter mud, cassava residues and grain bran are subjected to anaerobic fermentation, thus cellulose, hemicellulose and lignin in the raw materials are decomposed into small-molecular substances easy to absorb,and harmful substances such as sulfide and nitrite in the raw materials are degraded; the obtained feed contains a large number of substances such as bacterial proteins, active peptide, biological enzyme and organic acid which are derived by probiotics, the conversion absorption rate of the feed is increased, nutritional ingredients are balanced, growth of the freshwater fishes is promoted, the immune function of the freshwater fishes is enhanced, and the fish quality is improved; according to the feed, antibiotics, Skele-Gro and trace heavy metal are not added, nutrition is balanced, the feed is easy to absorb by the freshwater fishes, and the various fed freshwater fishes are high in survival rate, fast in growth, good in fish quality, free of fishy smell, and sweet in taste; and the feed contains various active microorganisms, harmful substances in water can be decomposed, and the breeding environment is enhanced.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a pollution-free freshwater fish feed and a preparation method thereof. Background technique [0002] During the normal growth process, fish need sufficient compound feeds that are easy to digest and absorb and rich in various amino acids. Therefore, fish feed usually contains components such as protein, fat, vitamins and minerals. Although fish need various nutrients in the growth process, the nutrients in fish feed also need to be balanced with each other. Excessive protein not only cannot be fully utilized by fish, but will also be excreted in the form of nitrogen, polluting water quality. The fish feed in the prior art is usually combined by directly adding various nutrients, and the raw materials rich in various nutrients are combined by mixing. Although the obtained fish feed is rich in various nutrients, it is , fish are not well absorbed. In addition, the fish f...
