Fish feed capable of reducing water environment pollution and preparation method thereof

Abstract

The invention discloses a fish feed capable of reducing water environment pollution. The fish feed capable of reducing the water environment pollution is characterized by being prepared from the following raw materials in parts by weight: 40-42 parts of whole rice bran, 16-18 parts of bran, 35-37 parts of coconut oil cakes, 1-2 parts of rhododendron mariae, 2-3 parts of fresh ginger oil, 3-4 parts of fish head meal, 26-28 parts of tomato pomace, 24-26 parts of sickle alfalfa, 0.11-0.13 part of galactomannan enzyme, 8-9 parts of Chinese magnoliavine fruits, 1.2-1.4 parts of sparassis crispa polysaccharides, 10-11 parts of soybean phospholipid, and glucose. According to the invention, red yeast rice, a vitamin B1 solution, phosphatidyl choline and hyaluronic-acid-filled hives are adopted so as to prepare vitamin particles; and a coating layer is arranged over the outer walls of the vitamin particles so as to effectively protect activity of the nutrient particle. The fish feed is also capable of effectively improving digestion functions of the fish body, as well as promoting nutrient absorption.

Description

technical field [0001] The invention belongs to the field of fish breeding fermented feed, and in particular relates to a fish feed that reduces water environment pollution and a preparation method thereof. Background technique [0002] Fish breeding, rearing and stocking. Fish farming, also known as aquaculture, fish farming and pisciculture, is important in maintaining food supplies, fishing and expanding fishing areas. Many species have been successfully introduced into new areas through fish farming. There is a type of fish farming that involves keeping goldfish and tropical fish both as a profession and as a hobby. Others include keeping minnows as bait and keeping other fish in private waters. Large quantities of fish are farmed in many parts of the world and are mostly sold commercially. However, only a few species are successfully used for this purpose, including catfish, herring, carp and salmon. [0003] Protein is an important nutrient for the survival of fis...

Problems solved by technology

If you take too much protein, the protein that cannot be digested and utilized will be excreted in the form of nitrogen, which not only reduces the protein utilization efficiency of the body, but also increases the pressure on water quality management, and it is also easy to cause intestinal diseases.
