Cold water fish feed

Abstract

The invention relates to the technical field of feed, in particular to cold water fish feed which is composed of corn gluten meal, fish meal, sesame powder, shell powder, seaweed meal, rice bran, cicada pupa powder, animal viscera dry powder, olive oil, palm oil, water hyacinth powder, reed powder, cortex mori, radix stephaniae tetrandrae, folium perillae, semen psoraleae, herba elsholtziae, senecio scandens, herba lysimachiae, fructus gardeniae, honey, acidifier and granulation agent. A reasonable feed formulation is developed by combining growing characteristics of cold water fish, the feed which is balanced in nutrition, safe and nontoxic is provided for the cold water fish and contains a lot of protein, fat and probiotics, digestion and absorption of the cold water fish to the feed are promoted effectively, and healthy growing of the cold water fish is guaranteed. The feed can guarantee healthy growing of the cold water fish and can achieve the objective of improving a water body, effectively lower content of pollutants in the water body and increase survival rate of the cold water fish.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a cold-water fish feed. Background technique [0002] Cold-water fish refers to fish that are adapted to live and grow in lower water temperatures. Its characteristics are: high protein, low fat, delicious meat, and rich nutrition. , is considered by the industry as a natural green food, because of this, cold-water fish has become a fashionable aquatic product pursued by modern people, and has extremely high breeding value. [0003] Cold-water fish is a kind of fish that is easily infected with various diseases, and the incidence of infectious diseases is relatively high. In the process of large-scale farming, due to the continuous increase of the breeding density and the continuous expansion of the breeding area, once infected with diseases, it is often Cause cross-infection, eventually cause very serious economic losses, and will also cause immeasurable damage to the ecological e...

[0003] Cold-water fish is a kind of fish that is easily infected with various diseases, and the incidence of infectious diseases is relatively high. In the process of large-scale farming, due to the continuous increase of the breeding density and the continuous expansion of the breeding area, once infected with diseases, it is often Cause cross-infection, eventually cause very serious economic losses, and will also cause immeasurable damage to the ecological environment; China's cold-water fish farming is still in its infancy. After several years of farming, it has been found that cold-water fish have high mortality and relatively slow growth. However, the breeding efficiency of the breeder is greatly damaged. Although the breeder has made some improvements or updates in fish feed, feed additives or breeding methods, the survival rate or mortality rate and disease resistance of the fish have not been significantly improved. At the same time , cold-water fish farming has very high requirements on water quality, slightly polluted, that is, no survival, but cold-water fish is a carnivorous fish, and its growth and development require high-energy feed with comprehensive nutrition. Therefore, when breeding cold-water fish, some Breeders add high-quality fishmeal, bean cake, and wheat flour to the compound feed as basic raw materials, add a variety of vitamins, minerals, oils, etc., and increase the amount of input to further promote the growth of cold-water fish and achieve the purpose of rapid economic growth. However, such This method not only leads to unreasonable formula, which leads to the inability of cold-water fish to digest the feed to the maximum extent, and slow growth. At the same time, the residual feed residue may further pollute the water source, which accelerates the disease and even death of cold-water fish. Therefore, for The nutritional requirements of cold-water fish and the characteristics of the living environment require that it is of great practical and economic significance to prepare feed suitable for the survival and growth of cold-water fish. At the same time, it also provides a new way of thinking for cold-water fish farming.
