Description
Technical field
The invention belongs to aquaculture field, and in particular to a kind of cray winter cultural method.
Background technology
Freshwater lobster, cray is commonly called as, belongs to Arthropoda Crustacea Decapoda Palinuridae, head and chest are thicker
Greatly, shell is hard, delicious meat, is a kind of nutrient tonification food of low fat low cholesterol high protein.Freshwater lobster, which removes, to be had
Build is larger, and meat is fertile outer, and also growth cycle is short, and yield is high, the characteristics of eating miscellaneous strong adaptability, is particularly suitable for artificial commodity
Property cultivation.
The existing ripe greenhouse shrimp raising technology in China at present, by natural conditions such as manual control temperature, realizes South America
The winter cultivation of white shrimp, Macrobrachium rosenbergii etc., both improves economic benefit, and greatly enrich the dining table of people.Cray
Suitable water temperature is 9~40 DEG C, and the most suitable growth water temperature is 22~30 DEG C.In freshwater aquiculture, water temperature is maintained at more than 25 DEG C and is
It is good.
The food that cray makes has the characteristics of nutritious, nice delicious and widely welcome, but existing
Technology, the cultivation for cray still rests on the southern band of Plain one, for the north cultivate cray when, still exist
The problem passed the winter, winter cause a large amount of diseases of cray and death, and cray yield is difficult to reach the market demand.
Therefore, in order to solve the above-mentioned technical problem, it is necessary to one kind can effectively reduce the incidence of disease, the small dragon of yield is improved
Shrimp winter cultural method.
The content of the invention
The present invention proposes a kind of cray winter cultural method, and the cultural method causes cray in the winter time or cold ground
Area's 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 cray winter cultural method, 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 lobster is removed, Exposure to Sunlight 3~5 days, is obtained vacant
Pond, be then placed in clear water, depth of water 1.8m~2.2m of profundal zone, the depth of water of phytal zone is 0.9~1.2m, every mu 80~
100kg ratio plants pasture and water after launching lime disinfection, the decomposed microbial organic fertilizer of side suspension in pond, places veil,
Water temperature, dissolved oxygen amount and the pH value in pond are adjusted, obtains cultivating pond；
3) raise：Select length to be launched for 0.9~1.1cm shrimp seedling in the cultivation pond prepared to step 2), raised
Material is fed, and between late October to Second Year March, regulation pond temperature is 15~20 DEG C, feeds a Chinese medicine fodder daily,
Feeding volume is the 8~10% of lobster body weight；In Second Year March, regulation pond temperature is 22~26 DEG C to before catching, sooner or later daily
An animal fodder is respectively fed, feeding volume is the 10~12% of shrimp 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 imported fish meal, shrimp shell meal, earthworm powder, screw meat, dregs of beans and vinasse；The raw material of the Chinese medicine fodder
Including broad bean, cottonseed cake, B B-complex, earthworm powder, the Radix Astragali, Herba Lycopi, ginkgo leaf, Radix Codonopsis and the capsule of weeping forsythia.
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 15 DEG C~26 DEG C.
Preferably, the pasture and water in the step 2) are reed, water hyacinth or waterweed, and the area coverage of pasture and water accounts for pond
The 45~55% of area.
Preferably, the shrimp seedling injected volume in the step 3) is 20,000~2.5 ten thousand tails/mu.
Preferably, the parts by weight of each raw material are respectively 15~20 parts of imported fish meal, shrimp shell in the animal fodder
5~10 parts of 15~20 parts of powder, 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, cottonseed cake 20~
40 parts, 1~3 part of B B-complex, 1~3 part of earthworm powder, 1~3 part of the Radix Astragali, 1~3 part of Herba Lycopi, 0.5~1 part of ginkgo leaf, Radix Codonopsis 2
~4 parts and 2~4 parts of the capsule of weeping forsythia.
Beneficial effects of the present invention：
1st, cultivating pool is divided into phytal zone and profundal zone by the present invention, and cray can climb to shallow water when winter fine day
Lived in area；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 enters water-filling
Temperature regulation grows in favor of the life of cray.
2nd, lobster 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 lobster living environment can be ensured for a long time.Such a organic fertilizer can strengthen the respiration capability of shrimp, improve pond
Pasture and water oxygen-supplying amount inside the pool.
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, cottonseed cake, B B-complex, earthworm powder, the Radix Astragali, Herba Lycopi, ginkgo leaf, Radix Codonopsis and the capsule of weeping forsythia.Such feed
Cray resisting cold ability can be strengthened, help cray smoothly to cross the cold in winter in greenhouse moderate.Earthworm in animal fodder
Earthworm powder belong to high protein material can for lobster grow abundant protein be provided so that lobster it is Fresh ＆ Tender in Texture.
