Problems solved by technology

Floating compound feed is a kind of full-price compound feed. Because its density is lower than that of seawater, it floats on the surface of seawater. Floating feed has the advantages of being convenient for feeding and observing fish feeding. It is currently used in seawater cage culture in my country. The most widely used compound feed has many disadvantages: 1. Because the floating feed floats on the surface of the sea, the cultured fish need to feed in the upper layer of the water body, and the time for feeding is short, and the competition among fish schools is very fierce, which will cause The waste of feeding energy; two, the feed floats on the surface of the water body, and is easily concentrated to the edge of the cage under the influence of the wind and waves, which is not conducive to the feeding of the cultured fish; three, when the floating feed is fed, the soaking time in the water body is longer Because the amount of feeding is not easy to control, it is easy to produce a large amount of residual bait. After the residual bait disintegrates, it will not only cause waste of resources, but also cause serious pollution to water quality.
With the development of feeding technology at home and abroad, underwater feeding has gradually become the mainstream feeding method due to its scientific nature and adaptability, while floating feed cannot be used in underwater feeding machines, which also limits its application prospects

Abstract

The invention relates to a sea fish mixed feed for deepwater net cage culture and a manufacturing method thereof, and belongs to the technical field of forage processing. The mixed feed comprises the following components by weight: 0-15 parts of fish meal, 50-70 parts of an enzymatic protein raw material, 5-12 parts of soybean meal, 8-14 parts of flour, 4-6 parts of squid visceral meal, 4-6 parts of fish oil, 1.5-2.5 parts of mineral premix, 0.8-1.2 parts of vitamin premix, 0.3 -0.7 part of choline chloride, 0.5-1.5 parts of calcium dihydrogen phosphate, 0.5-1 part of coated lysine, 0.2-0.5 part of coated methionine, 0.4-0.8 part of an adhesive. The processing steps are as below: 1) preparing an enzymatic hydrolysis protein raw material; 2) preparing materials; 3) crushing; 4) mixing; 5) hardening and tempering, and granulating; 6) drying; and 7) cooling. The invention ha scientific formula and reasonable technology; and the forage can satisfy nutrition for juvenile fish growth, has excellent stability, durability and sedimentation velocity, is convenient for eating by fish, realizes high utilization rate and reduces environmental pollution.

Description

technical field [0001] The invention relates to a seawater fish compound feed suitable for deep-water cage culture and a preparation method thereof, belonging to the technical field of feed processing. Background technique [0002] In recent years, due to overfishing and aggravated environmental pollution, marine fishery resources are declining day by day, and seafood is far from meeting market demand. We can only rely on the development of mariculture to alleviate the pressure on seafood demand. [0003] Deep-sea anti-wind and wave cage culture is an intensive and modern seawater aquaculture method, which can improve the breeding conditions, improve fish quality, accelerate fish growth, reduce disease hazards, resist wind and wave invasion, high scientific content, and orderly management and many other advantages. The research on deep-sea anti-wind and wave cages in my country started relatively late, but it has developed very rapidly. The developed deep-sea anti-wind and ...
