A kind of crucian carp artificial cultivation method

Abstract

The invention provides an artificial carassius auratus breeding method, and relates to the field of aquaculture. The artificial carassius auratus breeding method comprises the following steps that pond cleaning and disinfection treatment are carried out on a fish pond before fries are put into the pond, water is injected into the fish pond, the fires are put in the pond one week after water injection, shrimps and snails are put in the fish pond; the fries are fed with a mixed feed with the protein content ranging from 39% to 40%, 10-20 kg of quicklime is put in the fish pond per mu according to the water quality conditions to regulate water quality, and the fish pond is replenished with fresh water at fixed periods. According to the artificial carassius auratus breeding method, additives are added into the mixed feed and achieve the effects of feeding promotion and growth promotion, source of raw materials of the additives is stable, the smell and taste requirements of carassius auratus for the mixed feed can be met, and the ingestion speed and feed intake are increased remarkably; the effective constituents and ratio of the additives of the feed are optimized by the inventor through long-time experiments, the feed promotion effect can be enhanced, the anti-stress capacity and the growth rate of carassius auratus can be remarkably increased, and the feed coefficient is reduced; the additives of the feed are safe, efficient and free of toxic and side effects in long-term use.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for artificially cultivating crucian carp. Background technique [0002] China is the world's largest aquaculture country and the only country in the world where aquaculture output exceeds fishing output. The output of aquaculture aquatic 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 industry has developed rapidly, and the average annual growth rate of freshwater aquaculture as the most productive farming model has remained stable at a relatively high rate of about 10%. In 2008, the total production of freshwater products in my country reached 22.973 million tons, of which the output of freshwater aquaculture was 20.725 million tons, accounting for 90% of the total production of freshwater products in my country, while the output of natural fishery was only 2.248 mil...

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.
