Description
Technical field
The present invention relates to cray raising technology field, and in particular to a kind of cray shrimp seedling breeding for paddy field aquaculture
Method.
Background technology
Cray, belongs to Arthropoda, and phase late 1930s is by Japanese incoming China.Cray has the cave that burrows
The life habit in residence and destroy dam, and threaten fry existence, certain destruction is caused to agricultural production and fish production
Act on, therefore early stage people are eliminated as harmful organisms always.In recent years, cray is chased after because of delicious meat
Hold in both hands, good market prospect, but because cray is propagated artificially less, people largely capture wild cray, make its Natural Population number
Amount is less and less, and supply falls short of demand in market, and price drastically rises.In recent years, propagate cray artificially more and more, all build mostly
Special culturing pool is made to be cultivated, and in rural area, the paddyfield water of large area is not utilized effectively, it appears it is more unrestrained
Take.
The content of the invention
The invention provides a kind of cray shrimp seedling propagation method for paddy field aquaculture.
The technical solution adopted in the present invention is：
A kind of cray shrimp seedling propagation method for paddy field aquaculture, comprises the following steps：
1) breeding pond is built, and builds the dykes and dams of breeding pond surrounding, a height of 1~2m of dykes and dams, and makees cure process, the dykes and dams gradient
75~85 ° are maintained at, mud in cleaning breeding pond is dried 3~7 days after cleaning, then with lime disinfection, removes harmful life
Thing, disinfecting time is 3~10 days, and then water inlet and delivery port are processed, and water inlet avoids other biological from entering, injury
Cray, or polluted water, delivery port avoid cray from escaping, breeding water matter maintenance, and injection 20 after the sterilization of breeding pond~
50cm clear water, appropriate pasture and water and appropriate water lily are planted after standing 6~15 days, it is ensured that water quality reaches the dispensing of cray seed shrimp
Standard；
2) shrimp seedling seed selection, in 9~October of last year or the seed shrimp of 3~April selection then, it is physique healthy and strong, activity to select requirement
Power is strong, body is smooth, appendage is complete, it is disease-free without wound, without attachment, 10 is more than the monthly age, specification up to 30~50 grams/fish, seed selection
Sex ration is 3：The seed shrimp breeding density that 1,9~October selects and remain is 100~150,000 grams/acre, and the seed shrimp that 3~April selects and remain is put
It is 80~double centner/mu to support density, seed put in a suitable place to breed before with 3% salt water dipping bath shrimp body 5~10 minutes, to kill parasite
And pathogenic bacteria；
3) seed shrimp is fed, and the spiral shell freshwater mussel meat mixing soya-bean cake of chopping is watered into slurrying full pool spilling head, promotes seed shrimp gonad development, is thrown
Feed the time be every morning, at dusk respectively feed 1 time, with dusk feed based on, account for the 70% of day feeding volume, March day feeding volume
It is the 2~3% of pond shrimp body weight, April is 4~5%, and May is 6~8%, is 2~3% after October, the seed shrimp nurturing period,
Change water 1 time within every 10~15 days, water 30% is changed every time；1 quick lime is used within every 20 days, consumption is 10,000 grams/acre or so, using converting
Water is added, and pH value is adjusted to 7~8.5, and oxygen increasing equipment is opened in good time, keeps the water-soluble oxygen of breeding pool inner water body in 5mg/L
More than；
4) shrimp seedling hatching, in May, the temperature of regulation breeding pool inner water body so that water temperature rises to 26 DEG C or so, adds
The quick lime of water is added, the pH value of regulation breeding pool inner water body is 7.5~7.8, it is young that quickening embryonated egg is hatched in female shrimp abdomen
Shrimp；
5) shrimp seedling is fed, and the 1st week after shrimp seedling hatching, feeds the soya-bean milk for grinding, and is fed 3~4 times daily, since the 2nd week, with
Feed the small fish of chopping, spiral shell freshwater mussel meat, butcher based on the animal fodders such as leftover bits and pieces or shrimp seedling special compound feed, appropriate collocation
The pasty fish food that the co-grindings such as corn, wheat, fresh and tender plant stem-leaf are processed into, early, evening respectively feeds 1 time, with evening feed for
It is main, the 70% of daily ration of feeding is accounted for, the young shrimp day of early stage every ten thousand tail feeds 0.25~0.4 kilogram, later by 10% of shrimp body weight in pond
Left and right determines day feeding volume, during shrimp seed rearing, changes water 1 time within every 7~10 days, and water 20~30%, every 15~20 days are changed every time
Using the content of calcium ion in a quick lime regulating water quality and increase water, to meet shrimp seedling degenerate cllipticity to calcareous demand,
The consumption of quick lime is 10,000 grams/acre or so, and method is to be watered slurrying full pool spilling head；
6) applicability is fed, in the cultivation by 25-30 days, after shrimp seedling shell 5~8 times, by the way of outing when entering
Change the water body in breeding pond, to have discharged the water body of organic fertilizer in rice field, the water of discharge is to breed numerous in pond for the water of entrance
Water body is educated, shrimp seedling is adapted to paddyfield water in advance；
7) shrimp seedling is selected, and selection physique healthy and strong, the shrimp seedling that energy is strong, body is smooth, appendage is complete are used as dispensing to rice
The cultivation main body in field.
Beneficial effects of the present invention are：People by being applied directional during artificial breeding cray shrimp seedling of the invention
Work is intervened so that the cray for breeding out can better adapt to the growing environment in rice field, and the cray of cultivation can be with supporting rice
Field obtains the income of aquaculture, increases the income of peasant household, and on the one hand the cray grown in rice field increases can prey on grasshopper
Grasshopper insect and aquatic harmful organism, on the other hand, the fallen flowers of spike of rice can be as the food intake of cray.
