Abstract
The invention relates to a large-scale river crab cultivating method which comprises the following steps of good river crab selection, water quality regulation, ecological environment construction, biological active substance throwing and river crab disease control. The method is simple, low in cost and small in needed cultivating area, the cultivated river crabs are large in scale and free of public hazard, and the method is high in yield and remarkable in economic benefit.
Description
Technical field
The present invention relates to cultural technique field, particularly relate to a kind of large gauge method for breeding river crab.
Background technology
The development of culture of Chinese mitten crab scale.Culture of Chinese mitten crab approve by increasing people, area constantly expands, and output improves constantly, and benefit constantly promotes.Along with people's improving constantly river crab quality requirement, all wish to be able to eat specification large, the appearance of the trend of the measured river crab of matter, meet the requirement of this pair high-quality crab of people, just must improve cultural technique, cultivation large standard high quality river crab.The health of large gauge river crab is produced and not only can be improved cultured output and benefit, and is a kind of production model meeting the non-harmful product market demand.
Summary of the invention
It is simple, with low cost that technical problem to be solved by this invention is to provide a kind of method, and required cultured area is little, and the river crab specification of cultivation is large, and nuisanceless, output is high, the large gauge method for breeding river crab of remarkable in economical benefits.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of large gauge method for breeding river crab, comprises the steps:
Breeding variety river crab;
Regulating and controlling water quality;
The construction of ecological environment;
The input of bioactivator;
River crab disease control.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the technical essential of described breeding variety river crab is as follows:
Select the ChangJiang River neat specification of self-fertile, glossiness Juvenile Crab Eriocheir sinensis makes crab kind;
Requirement physique is healthy and strong, and appendage is complete, and creep speed is fast and without sick and wounded;
Reject " the little slow-witted crab " and not clear young crab of originating of not bringing up the sex premature of value;
Healthy high-quality crab kind is selected with or without parasite etc. from the incomplete degree of step, seed active situation, body surface.
Further, the technical essential of described regulating and controlling water quality is as follows:
Drained by the Chi Shui of crab farming during winter, remove the mud at the bottom of pond, reserved mud is no more than 10 centimetres;
Mud is exposed to the sun under the sun, splashes with quicklime; And remove swill every day;
High temperature season, regularly carries out photosynthetic bacteria full pool spilling head to culture pond;
To splash in pond quicklime, and application of phosphoric acid calcium dihydrogen.
Further, the technical essential of described the construction of ecological environment is as follows:
Select eel grass, hydrilla verticillata, waterweed very, water plant, fluitante plant in the waters of cultivating river crab, the optimum cultivated area of plant is 50 ~ 60% of water surface area.
Further, the technical essential of the input of described bioactivator is as follows:
In one-tenth crab culturing pool, every 667 square metres of waters surface throw in the spiral shell 150 ~ 250kg that lives, and allow its natural propagation.
Further, the technical essential of described river crab disease control is as follows:
The medicine used mainly contains quicklime, chlorine dioxide, strong chlorine oil, zinc sulphate, antibiotic and Chinese herbal medicine;
The consumption standard of common drug: quicklime every mu l0 ~ 15kg, changes water and splashes, zinc sulphate 2omg/L, and change water and splash, bait feeding made by antibiotic and feed, serve on 5 ~ 7 days;
To control worm and cure the disease and be combined together, take orally and combine with external application, Western medicine combines with Chinese medicine, different pharmaceutical cross-reference, and five is adopt chemoprophylaxis in advance.
The invention has the beneficial effects as follows: method is simple, with low cost, required cultured area is little, and the river crab specification of cultivation is large, and nuisanceless, output is high, remarkable in economical benefits.
