Semi-floating hemisalanx prognathus breeding feed and preparation method thereof

Abstract

The invention discloses a semi-floating hemisalanx prognathus breeding feed and a preparation method thereof. The feed is prepared from livestock and poultry scrap zymolyte, fish bone meal, Tongting lake asparagus leaf meal, green hay powder, cottonseed cake powder, bean cake powder, rape seed cake powder, S, S-dimethyl-beta-chloro propiothetin, human placenta powder, alfalfa seed powder, star aniseed powder, licorice root powder, cinnamon powder, dried orange peel powder, tomato peel powder, Japanese pagodatree leaf powder, hydroxypropyl modified starch and water. The prepared feed adopts a dual-layer structure, an inner layer is nutrient components, and an outer layer adopts a unique formula and has particular luring effects on hemisalanx prognathus. Through low-temperature puffing, the feed product is rich in fragrance and has good induction effects.

Description

technical field [0001] The invention relates to the field of aquatic feed preparation, in particular to a semi-floating whitebait breeding feed and a preparation method thereof. Background technique [0002] Silverfish, also known as noodle fish or ice fish, is a small fish with a slender body, translucent, naked and scaleless. "Dongting loquats are yellow, whitebait is fat and fragrant" refers to the Dongting Lake in May, where loquats are ripe, whitebait is on the market, and merchants gather to become a landscape of Dongting Water Town. Whitebait is rich in nutrition and has the characteristics of high protein and low fat. It is one of the important aquatic products exported in recent years. It is especially loved by consumers in Japan and Southeast Asia, and the research on breeding technology of whitebait has become a concern of people. Hot topic. [0003] At present, there are few research reports on whitebait feed in the market, and most people stay in the research ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few research reports on whitebait feed in the market, and most people stay in the study of feed formula. Folks also use livestock and poultry waste to put into fish ponds for whitebait breeding. Because there is a lot of hair in the livestock and poultry waste , fur, cuticle and other substances, although they can bring some nutrition to whitebait, but at the same time, they will also cause water pollution

Patent 201510508885.0 discloses a feed for whitebait breeding. The feed extruded by an extruder is put into aquaculture waters. This kind of feed produced by traditional particle extrusion without puffing process has a high density and cannot float, so it quickly floats. will sink to the bottom into the silt or bottom impurities

Because whitebait is a fish species that lives in the middle and lower waters, many whitebait that sink to the bottom of the feed cannot be eaten at all, which will cause a lot of waste

There are also floating feeds produced by conventional puffing technology. Such feeds can float on the water surface for about 30 minutes. Since there is no suspended matter to control the suspension, they will sink to the bottom quickly after absorbing water during the floating process, which is also not conducive to whitebait eating. , still cannot effectively solve the problem of feed waste
