Abstract
The invention discloses a kind of high crab cultivation method of survival rate, it is characterised in that selection including juvenile crab and dispensing, of fixed place and time feeds feed, Water-quality control and sterilization, daily management and Disease management.The juvenile crab of health is selected, is launched by female-male proportion；Fixed release position launches bait, control water depth；Water quality is detected, is carried out disinfection with quick lime, oxygenation is carried out by aerator；Pond is maked an inspection tour, clears up residual bait.
Description
Technical field
The present invention relates to cultivation field, and in particular to a kind of high crab cultivation method of survival rate.
Background technology
Crab is a kind of common shellfish, and the crabs of most species lives in the sea or neritic zone, also has
Some are dwelt in fresh water or land.Crab likes the water body environment that water quality is peace and quiet, transparency is larger into crab, and optimum is in pasture and water clump
It is raw, survived in the abundant water body of bait, thus more options pond, lake, river are swung with the Freshwater ecosystems such as rice field as crab
Cultivation base.Crab is a kind of delicious flavour and the food being easily absorbed by the body, depth are liked for people.
The content of the invention
The present invention solves the technical problem of providing a kind of survival rate high crab cultivation method, supported according to the technique
The crab survival rate grown is high, quality is high, the speed of growth is fast.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of high crab cultivation method of survival rate, it is characterised in that carry out according to the following steps：
A. the selection and dispensing of juvenile crab：
The healthy juvenile crab that selection step is complete, it is active to creep, good without disease-free, neat specification, glossiness is hindered, puts
Enter in the pond water that water temperature is 10-20 DEG C and soak 3-5min, then put back to bank 10-20min, 2-3 times repeatedly, by every mu
900-1100 juvenile crab, male and female 3:1-2 ratio, which is slowly shaken, is launched, make juvenile crab it is dispersed enter water；
B. it is of fixed place and time to feed feed：
3-5 release position of every mu of selection, launches 3-4 bait, bait is uniformly sprinkling upon to shoal, each injected volume is daily
The 6-10% of crab body weight；
In the juvenile crab stage according to 1:2:1-2 ratio launches fishes and shrimps slurry, corn, mixed feed made of bean curd, now water depth
30-40cm；
2 are pressed in crab growth phase:3:1-2 ratio launches sweet potato, pumpkin, mixed feed made of potato；Now water is deep
60-80cm；
In crab weightening, the stage of ripeness according to 3:2:1:1-2 ratio launches the manufactured mixing of small fish, spiral shell, potato, wheat
Bait, now water depth 1-1.2m；
When the average weight of crab is 140-160g, captured using drift net, crab pot captures, mesh bag captures or done pool capture
It is edible that method carries out capture；
C. Water-quality control and sterilization：
Pond dissolved oxygen content is 5-9mg/L, and the cultivation water hardness is 200-350mg/L, and the transparency of water body is 40-60cm, often
Uniformly splashed with quick lime every 15-25 days full pond, apply calcium dihydrogen phosphate 1-2 time, weekly replacing water once, each quantity of exchanged water
For 30-50%；
When water temperature raises, daily night opens aerator running 4-6h；
D. daily management and Disease management：
In the breeding process of crab, pond is maked an inspection tour sooner or later, pond situation, observation is checked and records, and adjust cultivating condition, and
Shi Qingli residual baits, foreign matter is removed, periodically food platform is carried out disinfection；Pond delivery port and water inlet wire netting surrounding use
Close eye net covering, guards against insect and enters pond.
Wherein, pond surrounding is with plastic sheeting described in step a, is surrounded provided with water inlet, delivery port and with wire netting,
Provided with aerator, cultivation accounts for pond area 55-65% water lettuce or water peanut.The dosage of quick lime described in step c is every mu
10-12kg, the dosage of calcium dihydrogen phosphate is every mu of 2-3kg.
The present invention reaction mechanism and have the beneficial effect that：
First be put into water and further take out when launching juvenile crab, be repeatedly in order to allow juvenile crab progressively suction moisture and adapt to water temperature,
Its survival rate can be improved；Applying quick lime can not only sterilize, and add calcium ion content in water, promote crab
Shelling growth.The crab survival rate that is cultivated is high, quality is high, the speed of growth is fast.
Water inlet and delivery port have been surrounded with wire netting, has placed fence and plastic sheeting, has prevented crab from escaping；Pass through oxygenation
Machine and flexible pipe are oxygenated into pond, in case crab is suffocated；Water plant is cultivated, only not young crab provides feed, provides and dwell
Sheltered situation is ceased, can also be purified water.It is the culture pond green non-pollution, water quality safety, nutritious, available for crab
Cultivation.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
