Problems solved by technology

[0003] In recent years, the modern facility fishery featuring the land-based RAS farming model has developed rapidly, and has high requirements on the water quality of the aquaculture. However, the high-density, concentrated feed aquaculture model often causes residual bait and feces to easily collapse, which in turn leads to deterioration of water quality, resulting in Coho salmon are in a state of intense stress, seriously affecting their growth, health and surrounding environment
The feed fed in production often cannot meet the nutritional needs of coho broodstock for growth and breeding. In addition, the feed has poor stability in water, resulting in low feed efficiency and easy pollution of water quality, resulting in slow growth and unsatisfactory maturity of coho broodstock, which in turn affects the growth of coho broodstock. quality of fertilized eggs

Abstract

The invention discloses an environment-friendly compound feed for land-based RAS culture of silver salmon parent fish and a preparation method of the environment-friendly compound feed. The feed is prepared from 25-35% of white fish meal, 10-15% of puffed soybean protein, 5-10% of high gluten flour, 5-10% of chicken meal, 5-10% of krill meal, 3-5% of squid meal, 3-5% of beer yeast, 3-5% of alpha-starch, 1-2% of vital gluten, 0.5-1% of natural montmorillonite, 10-15% of fish oil, 3-6% of soybean oil, 1.5-3% of a nutrient supplement, 0.5-1% of compound mineral salt and 0.5-1% of compound vitamins. The preparation method comprises the following steps: coarsely crushing, weighing according to a ratio, mixing, carrying out superfine crushing, carrying out secondary mixing, puffing, drying, carrying out vacuum treatment, and spraying, so that nutritional ingredients contained in the feed can meet the growth and breeding requirements of silver salmon parent fish, the quality of ova, the brood amount, the hatching rate and the survival rate of fry are improved, and the feed is suitable for large-scale popularization and application. The growth and breeding efficiency of the silver salmon parent fish is effectively improved, residual feed and excrement can be formed and are not prone to collapsing due to addition of the natural efficient adhesive, the residual feed and the excrement can be recycled in time to keep water clean, and therefore the breeding water environment is maintained.

Description

technical field [0001] The application relates to the technical field of aquatic feed, in particular to an environment-friendly compound feed for land-based RAS breeding coho broodstock and a preparation method thereof. Background technique [0002] Coho salmon (Oncorhynchus kisutch), also known as coho salmon, belongs to Herringoformes, Salmonidae, and the genus Salmon. The sea grows into adult fish in the sea and then migrates to fresh water to lay eggs to complete its growth cycle. The flesh of coho salmon is bright orange and has a good taste, which can arouse people's appetite. It is an excellent raw material for making sashimi and other delicacies. Because it is rich in unsaturated fatty acids, it can effectively prevent cardiovascular and cerebrovascular diseases and diabetes, etc. some diseases. Accordingly, some provinces in Canada are funded by the government to make public service advertisements on TV, advising people to eat more cold-water fish like coho to pre...
