Anti-stress health-care type pelteobagrus fulvidraco ecological feed

Abstract

The invention discloses an anti-stress health-care type pelteobagrus fulvidraco ecological feed. The feed has the characteristics of comprehensive nutritional ingredients, rich animal protein, multiple rich vitamins, minerals and the like, and accords with the requirement for ecological aquaculture of pelteobagrus fulvidraco. The feed can be prepared for instant application, is convenient to store and use, and has the effect of improving the immunity of pelteobagrus fulvidraco. After the feed prepared according to the formula is used for feeding, pelteobagrus fulvidraco has good palatability, can easily digest and quickly absorb the feed, and has high utilization, so that feed waste can be reduced, waste discharge can be reduced, and the pelteobagrus fulvidraco has high growing speed, strong disease resistance, high breeding survival rate and good meat quality. The feed has a good breeding effect for fingerling and adult fish of pelteobagrus fulvidraco, and the pelteobagrus fulvidraco bred by utilizing the feed is health and ecological, is high in quality, and accords with the requirement of people for ecological safety of foods. The ecological feed is wide in raw material source, and is simple, convenient and feasible to operate, reasonable in proportion and low in cost.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to an anti-stress and health-care type pelagic catfish ecological feed. Background technique [0002] Yellow catfish is a bottom-dwelling freshwater fish that people like to eat. It mainly lives in the middle and lower layers of rivers, lakes, reservoirs, and pits. At the bottom, it is a carnivorous omnivorous fish; due to factors such as overfishing and the reduction of steam feed, there are fewer and fewer wild yellow catfish, which cannot meet people's needs. Artificial breeding has become the main way of supply of yellow catfish . [0003] Yellow catfish is a benthic carnivorous omnivorous fish. The foraging activities of yellow catfish are generally carried out at night. The food includes small fish, shrimp, various terrestrial and aquatic insects, small molluscs and other aquatic invertebrates. Animals, sometimes also prey on small fish; the feeding habits of yellow c...

[0003] Yellow catfish is a benthic carnivorous omnivorous fish. The foraging activities of yellow catfish are generally carried out at night. The food includes small fish, shrimp, various terrestrial and aquatic insects, small molluscs and other aquatic invertebrates. Animals, sometimes also prey on small fish; the feeding habits of yellow catfish vary with the environment and seasonal changes, and they often swallow the eggs of other fish in spring and summer; artificial feeding is fed animal feed such as frozen sea fish , freshwater wild fish, earthworms, fly maggots, silkworm chrysalis and animal waste, etc., and also feed some powdery materials such as fish meal, bone meal, shrimp shell meal, corn meal, rice bran, wheat bran, etc. For raw material supply, only one or several of them are often fed. Due to the lack of nutrients, the yellow catfish grows slowly and has many diseases, which has a great impact on the water quality and is easy to damage the water quality and affect the growth environment of the yellow catfish; especially in the yellow catfish Under the conditions of high-density farming of catfish, when problems such as sudden changes in water temperature, insufficient dissolved oxygen, and improper production operations occur, the stress response of yellow catfish will often be caused, and diseases such as hepatobiliary syndrome and stress hemorrhagic disease of yellow catfish will be caused. Occurs frequently, often causing great losses to the farming and production of yellow catfish
