Freshwater fish phagostimulant

Abstract

The invention discloses a freshwater fish phagostimulant. The freshwater fish phagostimulant comprises following components in parts by weight: 8-12 parts of glycine, 6-10 parts of alanine, 5-8 parts of histidine, 4-6 parts of proline, 3-5 parts of arginine, 5-12 parts of glycine betaine, 3-8 parts of nori, 4-7 parts of purslane and 3-6 parts of radix acanthopanacis semticosi. According to the freshwater fish phagostimulant, the phagostimulant which is 0.1%-2% of the weight of freshwater fish compound feeds is added into the freshwater fish compound feeds so as to cover bad smell in the compound feeds and meanwhile stimulate sensory organs of freshwater fish to promote the freshwater fish to ingest and accelerate the growth; furthermore, the phagostimulant is used for inducing the freshwater fish to ingest so as to reduce residual feeds in a water body, increase the utilization rate of the feeds and reduce secondary pollution to the water by the residual feeds, and furthermore, disease risks of the freshwater fish are reduced and the survival rate of the freshwater fish is increased.

Description

technical field

[0001] The invention belongs to the technical field of aquatic animal additives, in particular to a freshwater fish food attractant. Background technique

[0002] my country is a big aquaculture country, and the aquaculture industry provides more than 30% of high-quality protein for our people, of which the total amount of freshwater fish farming accounts for 70% of my country's total fish production. Therefore, freshwater fish is an important part of my country's food security and one of the main sources of animal protein. The freshwater fish farming industry is developing rapidly, shifting from traditional natural stocking to high-density intensive breeding. The demand for aquatic feed continues to rise, and a large number of intensive breeding is almost entirely dependent on artificial feed. However, compared with traditional natural feed, artificial feed Flavor and palatability are often poor, and feed becomes a limiting factor for high-density intensive...
