The method comprises the following steps: pond selection, drainage facilities, blocking wall construction, pond cleaning, crab fry treatment and stocking, bait preparation and feeding, daily temperature and illumination management, etc. The breeding method for the high-quality crab disclosed by the invention can improve crab breeding environment, increase the yield of the crab, reduce the mortality of the crab, and improve the quality of the crab.
Description
Technical field
The present invention relates to aquaculture field, be specifically related to the cultural method of a kind of high-quality crab.
Background technology
Crab, also known as river crab, is fresh water crustacean, grows up in fresh water, crab delicious, nutritious.Crab contains rich in protein and trace element, has good tonic effect to health.Under the prerequisite that people are significantly improved in living standard, diet constantly increases the demand of aquatic products, add the continuous progress of modern aquaculture technology, a large amount of seafood products propagated artificially are increased gradually, and in cultural technique, there has also been innovation perfect.Crab has been Chinese and the universally recognized cuisines of overseas people at present, at present because the source of crab is still to fish for, it is less that artificial culture work is carried out, the crab of self-sow can not meet the eating requirements of people far away, although rely on the cultivation of small size to carry out the needs in supplementary market in recent years, equally do not alleviate the demand in market yet.The current equally technology for crab cultivation is also more chaotic, and the cultivation of most Dou Shi individual workship, efficiency is low, and quality is unstable, and crab lethality is high.
Summary of the invention
Object: in order to overcome above deficiency, discloses the cultural method of a kind of high-quality crab, thus improves crab cultivation environment, promotes crab output, reduces crab lethality, improves crab quality.
Technical scheme: in order to realize above object, the invention discloses the cultural method of a kind of high-quality crab, concrete steps comprise: (1), pond are selected: pond area is 1.5 ~ 2.5 mu, the depth of water 1.6 ~ 2.5 meters, dark 0.3 ~ 0.6 meter of pond bed mud soil, pond requires environment quiet, sunny, water source is abundant, water quality is pure and fresh, irrigation and drainage are convenient, is equipped with profundal zone and phytal zone; (2), water system is supporting: intake-outlet is established at the two ends in pond, and water inlet is located on the highest interface of water level, stretches in pond with cement culvert pipe, and delivery port is located at water inlet opposite; Intake-outlet all adopts wire netting to seal and pricks, and water inlet adds the pipe bag that cover bolting silk makes; (3), anti-wall of escaping builds: make coaming plate with cement plate, asbestos shingle, ore watt or aluminium sheet, bamboo timber supports, and thin wire is pricked and stitched, native top fractionation 0.5-0.8 rice, native bottom fractionation 0.2-0.5 rice, and arc is built up in corner; (4), pond is cleaned: crab carries out disinfection to pond before putting in a suitable place to breed; (5), process crab seed: crab seed is soaked 1-3 minute in pond water, takes out and place 15-20 minute, treat that crab seed progressively suctions moisture and water temperature; (6), crab seed is thrown in: 500-600 crab is thrown in every mu of pond; (7), bait is prepared; (8), throw in bait: throw in a bait every day, time the release time, 2 temperature were the highest in the afternoon, daily ration, feeding quantity by the 5%-8% of nursing crab gross weight; (9), daily management: sooner or later make an inspection tour pond, check pond situation, cleared up residual bait every 3 days, food platform carried out to once sterilizing and injected new water in a week, keeping pond water pure and fresh; (10), temperature and light-operated facility: safety glass cover is built in around pond and top, controls the light application time of 7 hours every days and holding temperature at 24 ± 2 degree.
The cultural method of further above-mentioned a kind of high-quality crab, the earth in pond described in it is clay or sandy soil or sub-sandy soil, thus ensures good air capacity of soils; And in pond, have one group of knoll, facilitate crab to climb out of water surface daylighting.
The cultural method of further above-mentioned a kind of high-quality crab, pond disinfection method described in it is with bleaching powder, puts into pond according to the ratio of 5g/ ton.
The cultural method of further above-mentioned a kind of high-quality crab, latter 3 days of bleaching powder sterilization described in it, throws in the organic fertilizing top soil of 150kg within pond.
The cultural method of further above-mentioned a kind of high-quality crab, in pond described in it, plantation or input pasture and water, mould the atmosphere similar to natural growing environment.
The cultural method of further above-mentioned a kind of high-quality crab, whole pond is rendered in crab bait dispersion described in it.
The cultural method of further above-mentioned a kind of high-quality crab, the number of elements throwing in crab seed described in it is every mu of 500-600, and female-male proportion is the crab seed of 3:1.
The cultural method of further above-mentioned a kind of high-quality crab, the bait prepared described in it comprises small fish 40-50 part, pumpkin 35-45 part, potato 15-25 part, wheat 10-20 part.
The cultural method of further above-mentioned a kind of high-quality crab, described in it, safety glass cover is provided with the shadow shield of skylight and automatic open-close, and is provided with thermostat in cloche, thus can maintain duration and steady temperature at constant sunshine.
Beneficial effect: a kind of crab cultivation method of the present invention, efficiency is high, can effectively improve crab growing environment, improve the seed output and quality of crab, reduce rate of falling ill and the lethality of crab in breeding process, make cultivation crab out more healthy, quality is better, increases economic efficiency greatly.
