Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of winter cultural method of crab.
Background technology
Crab is also known as river crab, is fresh water crustacean, is grown up in fresh water, crab delicious, nutritious.Crab mesh
It is preceding by Chinese and the universally recognized cuisines of overseas people.Culture of Chinese mitten crab production on, also have been achieved with from quantity velocity profile to
The transformation of quality and efficiency, changed from " big crab farming " to " bringing crab up ", especially more focused on ecological, safe and environment-friendly, strong
The cultivation of health, nuisanceless aquatic products, to the quality requirement of aquatic products also more and more higher.
At present, the also rear many deficiencies of technology of crab, experience also imperfection of the people to artificial crab farming are propagated artificially.Cultivation
The bait that crab needs in different stage it is different, it is necessary to growing environment it is also different, many technical staff are when cultivating crab
Ignore the scientific offering of crab cultivation ecological environment, using industrial fits feed, blindness medication, cause the broken of crab ecological environment
It is bad, cause crab survival rate low, quality decline.For north cultivation crab when, the problem passed the winter still be present, winter causes
The a large amount of diseases of crab and death, crab yield are difficult to reach the market demand.
The content of the invention
The present invention proposes a kind of winter cultural method of crab, and the cultural method causes crab in the winter time or cold district
Cultivation is possibly realized, and reduces the incidence of disease, improves yield.
The technical proposal of the invention is realized in this way：
A kind of winter cultural method of crab, comprises the following steps：
1) pond selection and structure：Selection is had abundant water resources, sludgeless pond, and pond includes phytal zone and the surrounding in center
Profundal zone, between the two with chamfered transition；The profundal zone in pond opens up intake-outlet, and intake-outlet sets the mistake of 30~50 mesh
Filter screen, the madial wall in pond and the bottom of phytal zone are provided with temperature sensor；Warmhouse booth, greenhouse are built above pond
Greenhouse uses thin-film package, the configuration heat-preserving equipment in thin film exterior layer plus a cap rock, warmhouse booth；
2) pond disinfection is handled：The water being allowed to dry in pond, the natural enemy biology of crab is removed, Exposure to Sunlight 3~5 days, is obtained vacant
Pond, be then placed in clear water, depth of water 1.5m~2m of profundal zone, the depth of water of phytal zone is 0.5~1m, every mu of 80~100kg
Ratio launch lime disinfection after plant pasture and water, the decomposed microbial organic fertilizer of side suspension in pond, place veil, regulating reservoir
Water temperature, dissolved oxygen amount and the pH value on the pool, obtain cultivating pond；
3) raise：Juvenile crab is put into the cultivation pond of step 2) preparation, water temperature is at 10~20 DEG C when launching juvenile crab, cultivation
Density is every mu of 600~700 crabs；Between late October to Second Year March, regulation pond temperature is 10~20 DEG C, often
It feeds a Chinese medicine fodder, and feeding volume is the 8~10% of crab body weight；In Second Year March pond temperature is adjusted to before catching
For 15~25 DEG C, an animal fodder is respectively fed sooner or later daily, feeding volume is the 10~12% of crab body weight；
Wherein, the decomposed microbial organic fertilizer is cow manure and the decomposed obtained mixture that ferments of fresh milk；It is described dynamic
The raw material of physical property feed includes fish meal, corn flour, earthworm powder, screw meat, dregs of beans and vinasse；The raw material of the Chinese medicine fodder includes
Broad bean, earthworm powder, B B-complex, photosynthetic bacteria, chlorella, Herba Lycopi, ginkgo leaf, Radix Codonopsis and the root of Dahurain angelica.
Preferably, 10 points to second day 4:00 AMs of the late into the night in winter fill 5~10 DEG C of warm water to the profundal zone in pond, with
The water temperature in pond is maintained at 10 DEG C~25 DEG C.
Preferably, the pasture and water are waterweed, eel grass or hydrilla verticillata, pasture and water coverage rate account for the pond gross area 60~
80%.
Preferably, the parts by weight of each raw material are respectively 15~20 parts of fish meal, corn flour 15 in the animal fodder
5~10 parts of~20 parts, 20~30 parts of earthworm powder, 10~20 parts of screw meat, 10~20 parts of dregs of beans and vinasse.
Preferably, in the Chinese medicine fodder parts by weight of each raw material be respectively 30~50 parts of broad bean, corn flour 20~
40 parts, 1~3 part of B B-complex, 1~3 part of photosynthetic bacteria, 1~3 part of chlorella, 1~3 part of Herba Lycopi, 0.5~1 part of ginkgo leaf,
2~4 parts of 2~4 parts of Radix Codonopsis and the root of Dahurain angelica.
Beneficial effects of the present invention：
1st, cultivating pool is divided into phytal zone and profundal zone by the present invention, and crab can climb to phytal zone when winter fine day
Lived；When late into the night temperature sensor detects that the water temperature of profundal zone is too low, the warm water of 5~10 DEG C of filling carries out water temperature
Adjust and grown in favor of the life of crab.
2nd, crab cultivation method of the invention reasonably plants pasture and water, places decomposed micro- life by reasonably planting pasture and water
Organic fertilizer, the diversification of crab living environment can be ensured for a long time.Such a organic fertilizer can strengthen the respiration capability of crab, improve
Pasture and water oxygen-supplying amount inside pond.
3rd, Chinese medicine fodder is fed between late October to Second Year March in cultural method of the invention, the Chinese medicine fodder
Raw material include broad bean, earthworm powder, B B-complex, photosynthetic bacteria, chlorella, Herba Lycopi, ginkgo leaf, Radix Codonopsis and the root of Dahurain angelica.Such
Feed can strengthen crab resisting cold ability, help crab smoothly to cross the cold in winter in greenhouse moderate.Earthworm in animal fodder
Earthworm powder belong to high protein material can for crab grow abundant protein be provided so that crab it is Fresh ＆ Tender in Texture.
