Abstract
The utility model discloses a green crab concealing device, which comprises pipe bodies placed at the bottom of a pond, wherein the diameter of the pipe body is 10-75 cm; the length of the pipe body is 20-30 cm; the peripheral wall of the pipe body is provided with many small holes; the number of the small holes on the peripheral wall of the pipe body is 20-50; and the placement space of the pipe bodies at the bottom of the pond is 40-80 cm. In the device, the diameter of the pipeline allows that green crabs enter the pipeline transversely, and full stretch of large claws of the green crabs is limited, so that the green crabs are prevented from being attacked by each other; water flow in the pipe body is smooth, and the device is environmentally-friendly and is a good shelling concealing object, so that the breeding survival rate is increased; and the device has the advantages of convenience in material source, easiness in manufacturing and low cost, and can be widely applied to green crab breeding.
Description
Technical field:
The utility model relates to a kind of aid of aquaculture, a kind of specifically hidden device of mud crab that the sheltered situation is provided for mud crab.
Background technology:
Things concealed is set to prevent and reduce the touch opportunity between crab and the crab; Its shell of feeling at ease is grown up, lay some barriers and things concealed in the Ying Zaichi, as plug bamboo branch, the branch of several rows quincuncial pile shape; Branch pole cuttage distance is between 30 centimetres～50 centimetres; Place thick bamboo tube, the brick and tile sheet, facilities such as artificial cave are made things concealed.Things concealed is set, can increases mud crab and hide and the movable space of perching, reach dispersions, estranged mud crab troops, and reduces the purpose of meeting, and can make mud crab in Various Seasonal again, different growing stages is freely selected the habitat of adaptation.But can there be problems such as flowing water is obstructed in the hidden device of existing mud crab, and some hidden device can't limit the big chela of mud crab fully and open, so effect still is undesirable.
The utility model content:
The purpose of the utility model is defective and the deficiency to above-mentioned prior art, can avoid mud crab to accuse each other for mud crab provides good sheltered situation for people provide a kind of, improves the hidden device of mud crab survival rate.
For realizing that the technical scheme that above-mentioned purpose the utility model is taked is: the hidden device of this mud crab comprises the body that is positioned over pond bottom, and the diameter of body is 10-75 centimetre, and the length of body is 20-30 centimetre, offers a plurality of apertures at the perisporium of body.
The little hole number of said body perisporium is 20-50.
Described body is 40-80 centimetre in the placement spacing of pond bottom.
The utility model pipe diameter is allowed the entering of walking crosswise of mud crab, and the big chela of restriction mud crab is opened fully, thereby avoids the mutual attack of mud crab, and current are unobstructed in the body, and Environmental security is the concealed body of good shell, cultures survival rate thereby improve.And the utility model needs only direct intercepting pvc pipe, has material source conveniently, makes simply, and advantage with low cost reaches more than 75% the mud crab ratio of living in caves, and survival rate improves more than 15%, can be widely used in blue crab cultivation.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
As shown in Figure 1, the utility model is that the hidden device of a kind of this mud crab comprises the body 1 that is positioned over pond bottom, and the diameter of body 1 is 10-75 centimetre, and the length of body 1 is 20-30 centimetre.The material of body is polyethylene (PVC) and analog, therefore as long as direct intercepting pvc pipe has material source conveniently, makes simply advantage with low cost.The perisporium that can be employed in body 1 offers a plurality of apertures 2, and aperture 2 quantity of said body 1 perisporium are 20-50, makes body 1 interior current unobstructed.Described body 1 is 40-80 centimetre in the placement spacing of pond bottom, and the mud crab ratio of living in caves is reached more than 75%, and survival rate improves more than 15%.
The utility model pipe diameter is allowed the entering of walking crosswise of mud crab, and the big chela of restriction mud crab is opened fully, thereby avoids the mutual attack of mud crab, and current are unobstructed in the body, and Environmental security is the concealed body of good shell, cultures survival rate thereby improve.And the utility model be as long as just can make through discarded pvc pipe etc., and it is convenient to have a material source, making simply, advantage with low cost reaches more than 75% the mud crab ratio of living in caves, survival rate improves more than 15%, can be widely used in blue crab cultivation.
