Description

Ecologically breeding river crabs method
Technical field
The invention belongs to culture of Chinese mitten crab field, and in particular to a kind of ecologically breeding river crabs method.
Background technology
Crab is also known as river crab, is fresh water crustacean, grows up in fresh water, and river crab meat flavour is delicious, full of nutrition.River 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, is 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, it is also higher and higher to the quality requirement of aquatic products.
For now, simple pursuit in the past that high density launch, the small dimension commodity crab of high yield, there is no Competitive advantage, in response to the market demand, it is difficult to sell discomfort, and market price is low, and culture benefit is poor.Demand currently on the market It is high quality, the high-quality crab of big specification, and is also the trend of development, not only product is fast-selling for it, and price is high, cultivation effect Benefit is good.Crab has been supported, has brought crab up, has supported high-quality crab, has supported health crab, has supported nuisanceless crab it is necessary to carry out the breeding way of health.It is so-called Healthy aquaculture, refers to the biological property according to river crab, crabs production is instructed with ecological principle, is that river crab builds one A good ecological environment for being conducive to river crab growth and development, makes river crab reduce disease to greatest extent during growth and development Occur, the commodity crab formed.Pollution-free, individual is big, and the full cream fertilizer of Huang, has good quality.Carry out innoxious management, it is ensured that river crab Cultivate the whole quality safety from pond to dining table and allow people to be able to eat the high-quality crab trusted.Only in this way, product could be in great demand Without hindrance, enterprise can just develop, the economic benefit and social benefit that cultivating river crab could obtain.
At present, the also rear many deficiencies of the technology of artificial cultured river crab, people are still not perfect the experience of artificial crab farming.Cultivation The bait that river crab needs in different stage it is different, it is necessary to growing environment it is also different, many technical staff are in cultivating river crab Ignore the scientific offering of culture of Chinese mitten crab ecological environment, using industrial fits feed, blindness medication, causes the broken of river crab ecologic environment It is bad, cause river crab survival rate low, quality decline.
The content of the invention
The present invention proposes a kind of ecologically breeding river crabs method, which, which builds, is conducive to the good of river crab growth Ecological environment, promotes river crab fast-growth, strengthens antiviral immunity power, improves the quality of river crab.
The technical proposal of the invention is realized in this way：
A kind of ecologically breeding river crabs method, comprises the following steps：
1) pond selects：The good waters pollution-free, bottom of pond is smooth of water quality is selected, places fence, builds up pond, pond is deep 0.8~1.2m, surrounding set the escaping-preventing facilities of 0.6m~0.8m high, open up intake-outlet in pond, and intake-outlet sets 30~ The filter screen of 50 mesh, the water being allowed to dry in pond, removes the natural enemy biology of river crab, solarization 3~5 days, obtains vacant pond；
2) pond environment is built：The hose of multiple gas outlets, hose and aerator phase are provided with bottom of pond and pool wall Even, it is oxygenated by aerator and hose into pond, in case river crab is suffocated；Then toward the water that 0.5~1m depths are put into pond, The ratio of 80~100kg plants water plant after launching lime disinfection per acre, launches the nutriment of sustained release, places veil, adjusts Water temperature, dissolved oxygen amount and the pH value in pond are saved, obtains cultivating pond；
3) juvenile crab is launched：Juvenile crab is put into pond, water temperature is at 10~20 DEG C when launching juvenile crab, and cultivation density is per acre 400~500 river crabs；Be provided with the water surface it is biological floating bed, it is described it is biological floating bed above be provided with gold and silver grass, it is biological floating bed Area account for the 2/3~3/4 of cultured area；
4) feeding management：During cultivating river crab, often to observe and adjust cultivating condition, pond water temperature 10~ 25 DEG C, 7.0~7.8, dissolved oxygen content will in due course be noted and renew water, change within every 5~8 days note once in 5~9mg/L pH value；First In week, feed 3~4 times daily, feeds the pellet of yolk, feeds amount day as the 100%~120% of crab storage, second week to the Seven weeks, feed daily 2~3 times, feed animal fodder, feed amount day as the 5%~8% of crab storage, feed 1~3 daily afterwards Secondary, the mixture of animal fodder and Chinese medicine fodder, feeds amount day as the 2%~5% of crab storage；
Wherein, the raw material of the animal fodder includes fish meal, collagen, earthworm powder, silkworm chrysalis, dregs of beans and jade Rice；The raw material of the Chinese medicine fodder includes rheum officinale, spirulina, multi-vitamins, photosynthetic bacteria, chlorella, betel nut, oriental wormwood, plate Blue root and Chinese ephedra.
Preferably, the water plant in the step 2) is eel grass, water peanut, waterweed or hydrilla verticillata, the covering of water plant Area accounts for the 45~55% of pond area.
Preferably, the nutriment of the sustained release in the step 2) is the mixing of kaolin, medical stone and well-rotted farmyard manure Thing, weight ratio 7:3:2.
Preferably, the water temperature in the pond of the step 2) is 10~25 DEG C, and pH value is 7.0~7.8, and dissolved oxygen content is 5 ~9mg/L.
Preferably, it is described it is biological floating bed be made of small mao bamboon, the biological floating bed length with it is wide be respectively 1.2~2.4m with 0.6~1m.
Preferably, the gold and silver grass is put into fixed container and is cultivated, and is then placed in above biological floating bed.
Preferably, the parts by weight of each raw material are respectively 15~20 parts of fish meal, fish skin collagen in the animal fodder 5~10 parts of protein 15~20 part, 20~30 parts of earthworm powder, 10~20 parts of silkworm chrysalis, 10~20 parts of dregs of beans and corn.
