The invention discloses a river crab lake area net-enclosure culturing method, and relates to the technical field of aquaculture. The river crab lake area net-enclosure culturing method comprises the following steps of water area selection, construction of net-enclosure facilities, juvenile crab stocking, bait feeding, disease prevention and treatment, daily management and capture and selling. The river crab lake area net-enclosure culturing method has the advantages that production resources are made full use of, no professional equipment is required, breeding pollution is avoided, the breeding technology is standard, feed supply is scientific and standard, the cultivation technology is improved to a large extent, and therefore the quality and the yield of river crabs are improved.

Description

A kind of territory, river crab lake lake Area method
Technical field
The present invention relates to technical field of aquaculture, be specifically related to territory, a kind of river crab lake lake Area method.
Background technology
River crab, also cries " crab " or " eriocheir sinensis ", Arthropoda Crustacea animal.The carapace that head and chest are combined into is square circular, and quality is hard.Front end body has a pair, and side has two to very hard sharp crab tooth.Crab a pair appendage is foremost the foot of a chela, and surface covers with fine hair; 4 pairs of steps are had after the foot of a chela, flat-sided and longer; Abdominal appendage is degenerated.The male and female of river crab can distinguish from its belly: female belly is rounded, and male belly is triangle.Delicious flavour, nutritious, have very high economic worth, current culture of Chinese mitten crab technology is varied, but due to its various management and addressing, the survival rate of cultivation is extremely low, and production output is also pessimistic.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can improve culture of Chinese mitten crab survival rate and scientific and normal territory, river crab lake lake Area method.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of territory, river crab lake lake Area method, is characterized in that: comprise the following steps:
(1), waters is selected:
Selection lakebed is smooth, has fine bourn, and submerged plant is luxuriant, and zoobenthos is enriched, and water quality is pure and fresh, and dissolved oxygen enriches, and pH value is more than 7.0, and the waters of normal water level between 80-150 centimetre cultivates.
(2), net encloses the construction executed:
1., the net setting of enclosing: it is 20-30 mu that net encloses size; net encloses employing two layers of mesh; skin is catch net, and internal layer escapes net, two layers of mesh spacing 5 meters for anti-; middle setting " cage net "; stratum reticulare topmost connects a T-shape reversal of the natural order of things mesh sheet or connects the wide plastic film for 20-40 centimetre, the connecing gabion bottom and imbed lakebed of net, and net encloses to be fixed in outside with bamboo stake; bamboo pile spacing is 1-2 rice, and it is highly 2.5-3.0 rice that net encloses.
2., Zan Yang district builds: new net encloses First Year Bu Shezanyang district, and arrange Zan Yang district after Second Year and account for the 30-40% that net encloses area, Zan Yang district is monolayer net structure, above establishes down net, and lakebed imbedded by underlying gabion.
(3), seed is put in a suitable place to breed:
The preparation of 1., putting in a suitable place to breed: the wild fishes class in adopting cage, silk screen elimination net to enclose before putting in a suitable place to breed.
2., crab kind is put in a suitable place to breed: crab kind specification 100-200/kilogram, stocking rate is 200-00/mu, time of putting in a suitable place to breed is at the beginning of by the end of March to 4 month, select weather fine warm, carry out when water temperature is higher, first crab kind is put into formaldehyde together with packaging bag when putting in a suitable place to breed and soak about 1 minute, take out placement and after 5 minutes, put into water immersion 2 minutes again, take out placement again 10 minutes, 2-3 time repeatedly, after the water suction of crab kind, put into Zan Yang district again.
3., crab kind secondary puts in a suitable place to breed: the pasture and water cultivating the 60-70% water surface in cultivation early stage, crab Zhong Congzanyang district could be put into large net and enclose at the beginning of mid or late June to 7 month.
(4), bait feeding
1., food species: choose vegetalitas, animal bait is thrown something and fed.
2., daily ration, feeding quantity: the 60-65% throwing total amount the 35-40% throwing annual total amount the first half of the year, the 7-11 month.Throw something and feed and throw the 10-15% depositing crab amount early stage, the later stage throws 5-10%.
3., bait-throwing method: bait throwing in secondary every day, when the morning 8,9 once, at dusk 5 time once.Feeding volume accounts for 1/3 and 2/3 of whole day respectively,
(5) disease prevention and cure:
1. crab kind or oneself supporting cultivation crab kind of the sick district occurred frequently of crab, is forbidden.
2. dipping is carried out before, putting crab kind in a suitable place to breed.
3., often within 15-30 days, splash once with 15PPM quicklime.
(6) daily management:
1., sooner or later patrol, observe water temperature, change of water quality daytime, at dusk and night observation river crab is movable, situation of eating food.
2., each weekly check keeps in repair once and reinforces and prevents escaping facility.
(7) sale is fished for
After annual October, sale is fished for one-tenth crab.
In described step (3)-3., crab Zhong Congzanyang district being put into method that large net encloses is put into large net after having caught with cage Wang Congzanyang district enclose and remove Zan Yang district after counting.
Vegetal bait of getting described in described step (4)-is 1. natural waterweeds and pumpkin, watermelon peel and the commodity bait such as various vegetables and soya-bean cake, soybean, wheat, corn such as duckweed, water peanut, bitter dish, hydrilla verticillata, p.malaianus, and described animal bait is that small fish, shrimp, silkworm chrysalis, spiral shell a species of small clam living in fresh water, pig blood and livestock and poultry offal are got a foothold, spoil.
The invention has the beneficial effects as follows: the present invention make use of the resources of production fully, without the need to professional equipment, pollute without cultivating, Cultivating techniques standard criterion, throwing is raised scientific and normal, improves the technology of cultivation significantly, thus improves the quality and yield of river crab.
