Embodiment 1

[0028] An ecological polyculture method for mainly raising grass carp, crucian carp and bighead carp:

[0029] 500 grass carp / mu of 50g / tail, 400 crucian carp / mu of 50g / tail, 140 bighead carp / mu of 100g / tail, 30 silver carp / mu of 30g / tail; the materials used are daily Use the full price compound hard pellet feed with 28% crude protein, or use the full price compound hard pellet feed with 28% daily crude protein and the full price compound hard pellet feed with 30% crude protein at the same time; the daily crude protein 28% % of the full-price compound hard pellet feed and the 30% crude protein full-price compound hard pellet feed are 5:3; one or any of photosynthetic bacteria, algae species, and bottom-improved products are used for water transfer Several combinations.

Embodiment 2

[0031] An ecological polyculture method for mainly raising grass carp, crucian carp and bighead carp:

[0032] Grass carp with 250g / tail is 1300 / mu, crucian carp with 150g / tail is 1000 / mu, bighead carp with 500g / tail is 300 / mu, silver carp is 500g / tail and silver carp is 100 / mu; Use the full price compound hard pellet feed with 29% crude protein, or use the full price compound hard pellet feed with 29% daily crude protein and the full price compound hard pellet feed with 30% crude protein at the same time; the daily crude protein 29% % of the full-price compound hard pellet feed and the 30% crude protein full-price compound hard pellet feed are 7:5; one or any of photosynthetic bacteria, algae species, and bottom-improved products are used for water transfer. Several combinations.

Embodiment 3

[0034] An ecological polyculture method for mainly raising grass carp, crucian carp and bighead carp:

[0035] 900 grass carp / mu of 150g / tail, 700 crucian carp / mu of 100g / tail, 220 bighead carp / mu of 300g / tail, 65 silver carp / mu of 265g / tail; Use the full price compound hard pellet feed with 28% crude protein, or use the full price compound hard pellet feed with 28% daily crude protein and the full price compound hard pellet feed with 30% crude protein at the same time; the daily crude protein 28% % full-price compound hard pellet feed and the 30% crude protein full-price compound hard pellet feed in an amount ratio of 3:2; water transfer uses one or any Several combinations.

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...
