Method for rearing megalobrama amblycephala

Abstract

The invention discloses a method for rearing megalobrama amblycephala, and relates to the field of aquaculture. The method comprises the steps that pond cleaning and disinfection are conducted on a fish pond before fry stocking; water is injected into the fish pond; fry stocking is conducted one week after water injection; stocking of shrimps and margarya is conducted in the fish pond; the fry arefed with mixed feed with the protein content of 32-34%; water quality is regulated by using quicklime with the amount of 10-20 kg per mu according to the water quality condition of the fish pond; fresh water is supplemented into the fish pond periodically. According to the method for rearing megalobrama amblycephala, the compound feed is added with an additive and has the function of inducing thefishes to eat and promoting the growth, sources of raw materials of the additive are stable, the osphretic and gustatory requirements of megalobrama amblycephala for the compound feed can be met, andthe intake speed and amount are obviously increased; the effective ingredients and proportion of the feed additive are optimized by an inventor after long-term experiments, the feed inducing performance is improved, the anti-stress capability of megalobrama amblycephala can be obviously improved, the growth speed of megalobrama amblycephala can be obviously increased, and meanwhile, the coefficient of the feed is reduced; the feed additive is safely and efficiently used for a long time and has no toxic side effect.

Description

Technical field [0001] The invention relates to the field of aquaculture, in particular to a Wuchang fish breeding method. 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). Freshwater fish f...

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.
