Special feed additive for breeding mandarin fish fries

Abstract

The invention relates to a special feed additive for breeding mandarin fish fries. The special feed additive is designed by combining traditional Chinese medicine culture of China and a large amount of breeding experience according to the growth physiological characteristics of the mandarin fish fries at a fry period. The special feed additive is particularly prepared from following raw materials in parts by weight: 5-7 parts of coptis chinensis, 10-12 parts of rehmannia glutinosa libosch, 3-5 parts of rhizoma anemarrhenae, 3-5 parts of gentiana scabra bunge, 6-9 parts of pericarpium citri reticulatae viride, 8-10 parts of dried ginger, 10-15 parts of cassia twigs, 3-7 parts of salvia miltiorrhiza bunge, 7-9 parts of radix stemonae, 6-9 parts of cortex acanthopanacis, 5-7 parts of moutan barks, 30-40 parts of mung beans and 30-40 parts of rice bran. The special feed additive can be used for obviously increasing the survival rate of the mandarin fish fries; compared with a regular compound feed which is not added with the additive, the survival rate is increased to 85-92% from 70%; the growth speed of the fish fries is also greatly increased and the economic benefits of breeding the fries are also improved by about 20%; the special feed additive has important meaning on the mandarin fish breeding industry.

Description

technical field [0001] The invention belongs to the field of feed and relates to a special feed additive for mandarin fish seedling cultivation. Background technique [0002] mandarin fish ( Siniperca chuatsi Basilewsky ) is a rare freshwater fish native to my country. It has the characteristics of beautiful body, tender meat, delicious taste and rich nutrition. At present, mandarin fish has become a must-have item in most aquatic product markets across the country, and it is also one of the must-have items in the live fish counters of many large supermarkets. volume will gradually increase. The breeding and market demand of mandarin fish has broad development prospects. [0003] The middle reaches of the Yangtze River is the main source of mandarin fish germplasm resources. The lakes in its basin are the natural habitat and fattening place for mandarin fish. In recent years. The artificial propagation technology of mandarin fish is relatively mature, and the industria...

Problems solved by technology

In recent years. The artificial propagation technology of mandarin fish is relatively mature, and the industrialization of mandarin fish farming in the country is developing rapidly, but the output of large-scale seedlings is far behind the growing demand of farmers

During the breeding period of mandarin fish seedlings and adult fish, compound feed is the main feeding method. However, there is no special compound feed for mandarin fish seedling cultivation on the market at present, while the compound feed for conventional mandarin fish adult fish There are often shortcomings such as unreasonable nutrient composition, low protein and vitamin content, poor palatability, etc., and are not suitable for the cultivation of mandarin fish seedlings

In addition, there are many pathogens in the seedling stage of mandarin fish, mainly including: trichomonas, oblique tube worms, tricis worms, saprolegnia, bacteria, viruses, shrinking worms, bell worms, small melon worms, half eyebrow worms, Japanese new bream, Chinese bream, anchor head bream, fish carp, etc., while the existing breeding technology mainly relies on water disinfection and antibiotic treatment for prevention and treatment, but this prevention and control method cannot very effectively prevent the occurrence of diseases, and the survival of the culture The rate is often around 60-75%, and the above methods will also cause water pollution and water quality deterioration. At the same time, the use of antibiotics will also lead to the increase of drug-resistant bacteria, making it more difficult to cure diseases, and antibiotic residues will also be affected by outsiders. consumer health
