Abstract
The invention relates to an ecological breeding method for eriocheir sinensis. The ecological breeding method comprises the following steps: firstly, determining a pond for breeding the eriocheir sinensis; secondly, in January to February every year, planting aquatic weeds in the breeding pond; thirdly, in February to March, breeding a crab species namely the eriocheir sinensis in the breeding pond; fourthly, in late March, throwing animal baits into the breeding pond; fifthly, in early April, starting to throw snails into the breeding pond; sixthly, in late April, erecting insecticidal lamps in the breeding pond; seventhly, in May to September, applying EM bacteria to the breeding pond; eighthly, in early August, starting to add plant baits into the breeding pond; and ninthly, in late August, starting to add animal baits into the breeding pond. According to the ecological breeding method provided by the invention, the amounts of mixed pellet feeds and other baits are greatly reduced, the production input cost is significantly reduced, and the assistant EM bacteria eliminate toxic harmful substances, so that water feed without water change is realized, any medicine is not applied, and the breeding of nuisance-free high-quality eriocheir sinensis is basically realized.

Power is vigorous, body colour is bright, and female Eriocheir sinensis kind or male Eriocheir sinensis kind average size are 80-100/kg, breeding density is 600-700
/667m2;
4th, late March, frost wild fishes of throwing something and feeding in cultivating pool, frost wild fishes shreds after high temperature cooks,
High temperature can kill pathogenic bacterium and the virus etc. that fish body may carry, and prevents from infecting Eriocheir sinensis body, and this wild fishes of throwing something and feeding is only Eriocheir sinensis kind
For the first time needed for shell, it is ensured that energy needed for shell for the first time, improve shell survival rate, day feeding volume be 0.4-0.5kg/667m2,
Temporarily stop after throwing something and feeding continuously 7;
5th, early April, start to throw in Bellamya quadrata to cultivating pool, throw in 3 times altogether, be respectively, early April, throw
High-volume 230-250kg/667m2, late May, injected volume 80-100kg/667m2, late June, injected volume
180-200kg/667m2, Bellamya quadrata is not only the main bait that supply Eriocheir sinensis is edible, also scalable water quality, is improved water body
Transparency, promotes that pasture and water work in coordination with symbiosis;
6th, late April, have in cultivating pool on the water surface that a large amount of pasture and water grow thickly and at 30-50cm, set up electric shock type
Trapping lamp, bottom pest catcher, airbreak is in the water surface, so that all kinds of insecticides killed fall in water, in being beneficial to be hidden in pasture and water
China's Eriocheir is ingested, and it sets up density is 45-50/667m2, during 19:00-21:00 every day, open work;
7th, the 5-9 month, every 15 days, by 1.5-2.0kg/667m250 times of EM bacterium are used former in cultivating pool
Dew diluent, uses Shi Quanchi and uniformly splashes, and EM bacterium can increase dissolved oxygen amount, and eliminating ammonia nitrogen, nitrite and sulfide etc. has
Poison harmful substance;
8th, early August, increase the niblet after throwing by the boiling of 50%-70% to cultivating pool and weight portion is
The vegetal bait that the Fructus Cucurbitae moschatae of 30%-50% is mixed, day feeding volume be 3.5-4.0kg/667m2, after throwing something and feeding continuously 25 eventually
Only, high temperature season is aided with that protein content is low, vitamin and the high vegetal bait of all kinds of content of mineral substances can strengthen Eriocheir sinensis body self
Immunity, is conducive to it steadily to aestivate;
9th, late August, the frost wild fishes of chopping after cooking of again throwing something and feeding in cultivating pool, this throws something and feeds wild miscellaneous
Fish is needed for Eriocheir sinensis forms final stage hepatopancrease and gonad Rapid development, it is ensured that Eriocheir sinensis body grossness and listing specification, day
Feeding volume is 5.5-6.0kg/667m2, terminate after throwing something and feeding continuously 20.
The present invention realizes only water inlet and does not change water, does not use any medicine, be not directed to part the most same as the prior art or
