An ecological polyculture method for mainly raising grass carp, crucian carp and bighead carp

Abstract

The invention relates to an ecological mixed culture method with grass carp, crucian carp and bighead carp mainly cultured, and belongs to the technical field of aquaculture. By means of the method, the benefits of culture households can be increased, and the ecological environment can be protected; the benefits of culture households are increased by selecting a specific stocking mode and specific stocking density and using a specific material use mode and a water transfer mode in cooperation; besides, water pollutants are converted into fish meat, and thus water pollution is controlled. According to the method, a large quantity of living food is provided for bighead carp and silver carp by increasing the bighead carp stocking quantity and using algae species, photosynthetic bacteria and low-calcium products to regulate water quality, water pollutants are converted into fish meat, and thus water pollution is controlled; fish live in a good environment, and thus fish diseases are reduced.

Description

technical field [0001] The invention relates to a polyculture method. More specifically, the invention relates to an ecological polyculture method for mainly raising grass carp, crucian carp and bighead carp, and belongs to the technical field of aquaculture. Background technique [0002] From 2014 to 2015, grass carp farming was affected by the general environment, and the market was sluggish. Generally, farmers were on the verge of losing money, especially in Central China, where grass carp is the main breeding area. The area has large water surface, and there are many water surfaces for intensive farming, but the yield per unit of farming is generally low. The average feeding amount per mu is about 1 ton, and the yield per mu is mostly less than 2,000 catties. Most of the farmers have a breeding scale of 10-20 mu, and the profit per mu is about 1,000 yuan. [0003] Central China mainly adopts the polyculture of grass carp and silver carp. Among them, grass carp has the hi...

Problems solved by technology

[0008] The present invention aims to solve the problem that the existing polyculture method for mainly raising grass carp is unreasonable, and there is no supporting material mode and water transfer mode, so that farmers cannot obtain the greatest economic benefits. It provides a method for mainly raising grass carp, crucian carp and The method of ecological polyculture of bighead carp can improve farmers’ benefits and protect the ecological environment. Through innovative stocking models, supporting the use of materials and water transfer models, farmers’ benefits can be improved, and water pollutants can be transformed into fish meat. to control water pollution
