The pool is discharged water 5-10cm, plants pasture and water, and platform of ingesting is set in pond center；（3）Juvenile crab was launched, 15 days or so the March of each year
Carry out juvenile crab dispensing；（4）Bait, daily every mu feeds 300 jin of the screw minced, 100 jin of soya-bean cake, from 5 after juvenile crab is launched
Start 600 jin of every mu of the feeding volume of screw, 200 jin of soya-bean cake month；（5）Pond water quality management, per two weeks by stagnant water and running water
Exchange once, exchange 30% every time, every month sterilizes once；（6）Crab shells；（7）Crab is ripe.
In a preferred embodiment of the present invention, step（2）In pasture and water line space be 50cm.
In a preferred embodiment of the present invention, step（5）Middle pond water quality pH value 7.5-8.5.
In a preferred embodiment of the present invention, step（6）In crab shelling for crab shell 4 times, for the last time 9
The beginning of the month.
In a preferred embodiment of the present invention, step（7）Crab maturation time in September No. 15 or so.
In a preferred embodiment of the present invention, step（2）In plantation pasture and water, pasture and water will be carried out every other month
Reseed in time.
The beneficial effects of the invention are as follows：The cultural method of changjiang crab of the present invention, this crab cultivation method is in breeding process
Control the transparency and oxygen content of water quality, it is possible to reduce the incidence of disease of crab, improve the yield of crab, add economic benefit.
