Problems solved by technology

[0003] The extensive use of chilled miscellaneous fish not only seriously damages marine resources and pollutes water quality, but also has a high bait coefficient and unbalanced nutrition. Farmed fish are prone to disease, high cost, low benefit, and poor quality
[0004] Floating feed also floats on the surface of seawater because its density is lower than that of seawater. Due to the short feeding time, the competition among fish schools is very fierce, which will cause a waste of feeding energy
The feed floats on the surface of the water body and is easily concentrated towards the edge of the cage due to the influence of wind and waves, which is not conducive to the feeding of farmed fish; due to the difficulty in controlling the feeding amount, 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 Great pollution to water quality

Abstract

The invention relates to a bullet-type suspension feeding structure specially for deep water net cage feeding machines and a formula of the feeding structure, and belongs to the technical field of fish feed. The feeding structure includes a bullet-type body integrally extruded by a forming machine; the middle part of the body is in a cylindrical shape, the tip end of the body is an in conical shape, and the rear part of the body is in a round cake shape; a circle of groove for suspension is arranged between the rear part and the middle part; and components include seafood protein, vegetable protein, grain, fish oil, soya lecithin, amino acid, mineral matters, vitamins and anti-oxidant. Through the proportion of feed formula and expansion temperature and process control during feed processing, feed can have a certain suspensibility. Through the bullet-type design of the extruded feed, the feed can have a certain sedimentation rate, and suspension time can be prolonged after the feed isput into water, so that the feed can reach deep water net cage areas, farmed fishes can conveniently eat the feed, and high feed utilization rate can be realized.

Description

technical field [0001] The invention relates to a special bullet-type suspension bait feeding structure for a deep-water net cage bait feeding machine and its formula, belonging to the technical field of fish feed. Background technique [0002] Due to the traditional deep-water cage culture, most of them use artificial or mechanical semi-automatic feeding of chilled miscellaneous fish and floating compound feed. [0003] The extensive use of chilled miscellaneous fish not only seriously damages marine resources and pollutes water quality, but also has a high bait coefficient and unbalanced nutrition. Farmed fish are prone to disease, high cost, low benefit, and poor quality. [0004] Floating feed also floats on the surface of seawater because its density is lower than that of seawater. Due to the short feeding time, the competition among fish schools is very fierce, which will cause a waste of feeding energy. The feed floats on the surface of the water body and is easily c...
