A kind of bream artificial breeding method

Abstract

A method for artificial breeding of bream, relating to the field of aquaculture, comprising the following steps: carrying out cleaning pond disinfection treatment on fish ponds before stocking fish fry; injecting water into the fish pond; stocking fish fry after water injection for one week; stocking shrimp and snails in the fish pond; Feed mixed feed with a protein content of 32% to 34%; according to the water quality of the fish pond, use quicklime to control the water quality at an amount of 10 to 20 kg per mu; regularly add fresh water to the fish pond. In the artificial breeding method for bream provided by the invention, additives are added to the compound feed, which has the effect of attracting food and promoting growth. The raw material source of the additive is stable, which can meet the smell and taste requirements of bream for the compound feed, and obviously speed up the feeding speed and improve the feeding rate. The effective ingredients and ratio of this feed additive have been optimized by the inventor in long-term experiments, which can significantly improve the anti-stress ability and growth rate of bream while strengthening the food attractant, and reduce the feed coefficient at the same time; the long-term use of this feed additive Safe and efficient, no toxic side effects.

Description

Technical field [0001] The invention relates to the field of aquaculture, in particular to a method for artificial breeding of bream. Background technique [0002] China is the world's largest aquaculture country and the only country in the world whose aquaculture output exceeds the catch output. The output of aquaculture products accounts for 70% of the world, and aquaculture occupies a very important position in the national economy. In recent years, my country’s aquaculture has developed rapidly, and freshwater aquaculture, as the most productive aquaculture model, has maintained an average annual growth rate of about 10%. In 2008, my country’s total production of freshwater products reached 22.973 million tons, of which freshwater aquaculture production was 20.725 million tons, accounting for 90% of my country’s total freshwater product production, while natural fishery production was only 2.248 million tons, accounting for about 10% (China Statistics Yearbook, 2009).

Problems solved by technology

In recent years, due to the use of plant protein and some low-value raw materials in the feed, the feed attraction and growth of some farmed fish have been greatly affected, resulting in reduced food intake, slow growth, and high mortality. This situation has seriously hindered the further development of the freshwater fish farming industry and the feed manufacturing industry.
