High-performance biological forage grass for aquaculture and preparation method thereof

Abstract

The invention discloses high-performance biological forage grass for aquaculture and a preparation method thereof. The forage grass is prepared from the following raw materials in parts by weight: 55-65 parts of corn straw, 10-15 parts of grain amaranth, 20-30 parts of typha angustifolia, 18-24 parts of mesona, 10-15 parts of common papermulberry, 16-22 parts of salicornia herbacea, 15-20 parts ofred clover, 15-20 parts of scabrous doellingeria rhizome and roots, 12-18 parts of bermuda grass, 10-15 parts of lapsana apogonoides, 10-15 parts of amur foxtail, 8-14 parts of festuca arundinacea, 5-10 parts of ragi, 5-10 parts of white sweet clover, 4-8 parts of a Chinese herbal medicine additive and 0.5-1 part of a microbial additive. The biological forage grass prepared by the preparation method has balanced and comprehensive nutrients, good palatability and high conversion rate, can increase the ingestion amount of fish, improve the immunity of the fish, accelerate healthy growth of thefish, improve the survival rate of the fish and improve the culture benefit, is free of antibiotics and drug residue, safe and environmental-friendly, and also has the effects of reducing eutrophication of a water body, increasing dissolved oxygen in the water body and improving the environment of the water body.

Description

field of invention [0001] The invention relates to a high-performance aquaculture biological forage material and a preparation method thereof, belonging to the technical field of aquaculture. Background technique [0002] As early as the end of the Yin Dynasty in the 11th century BC, there were records of pond fish farming in my country. Nowadays, pond fish farming is already the main form of raising food fish in my country. Especially in the freshwater aquaculture industry, its output accounts for more than 75% of the total output of freshwater fish farming in the country. In the cultivation process of food fish, the use of artificial pellet feed is a kind of cultivation mode as the main technical means of pond fish cultivation, and has been generally accepted by farmers in production. However, this intensive high-density farming leads to the destruction of the breeding ecological environment, and greatly increases the chance of cross-infection of pathogens among aquatic ...

AI Technical Summary

Problems solved by technology

However, this intensive high-density farming has resulted in the destruction of the breeding ecological environment and greatly increased the chance of cross-infection of pathogens among aquatic animals.

The use of drugs to control the occurrence of diseases is the main means at present, but the extensive use of antibiotics not only increases the resistance of bacteria, destroys and interferes with the normal microbial flora of the breeding environment, but also makes antibiotics remain and enrich in the fish, which eventually poses a threat to the human body. harm
