Abstract

The utility model relates to a cylindrical shielding device for breeding crabs. The cylindrical shielding device comprises a net sheet and a clamp device, wherein one side of the net sheet is bent to form a cylinder with two open ends, and the other side of the net sheet stretches naturally; the clamp device is arranged at the junction of the cylindrical part and stretched part of the net sheet; and small holes are distributed on the net sheet. The cylindrical shielding device disclosed by the utility model can solve the problem that the crabs kill one other in a breeding process, reduce the probability that the crabs kill one other, and avoid the danger that the crabs are infected by diseases when the crabs are injured during killing, so that the survival rate of the crabs can be obviously improved; and the cylindrical shielding device has a reasonable and simple structure and is low in cost, convenient to operate and strong in practicability, thus having broad application prospect.

Description

A kind of cylindric crayfish culture masking device
Technical field
The utility model belongs to technical field of aquaculture, particularly relates to a kind of cylindric crayfish culture masking device.
Background technology
Crab is one of important aquatic products of China, and is delicious with its meat flavour, nutritious and liked by masses.But because crab is the violent animal of a kind of habit, the cannibalisation rate is high in the breeding process, especially when shell, very easily receives other individual attacks, thus bacteria infection, survival rate is lower, and the breed difficulty is bigger.Like domestic common mariculture kind mud crab and swimming crab, the breed survival rate of crab class is at 10%-20% under traditional breeding way, and its most important reason is that the crab class phenomenon that cuts one another's throat is serious.
Summary of the invention
The utility model technical problem to be solved provides a kind of cylindric crayfish culture masking device; Can solve the problem that cuts one another's throat in the crayfish culture process; Reduced the probability that the crab class cuts one another's throat; Simultaneously also avoided danger, thereby significantly improved the survival rate of crayfish culture because of the injured introduced disease that cuts one another's throat.
The utility model solves the technical scheme that its technical problem adopted: a kind of cylindric crayfish culture masking device is provided; Comprise net sheet, clamping device; Described net sheet one lateral bending is rolled into the cylindric of both ends open; Opposite side stretches naturally, and the junction of described net sheet cylindrical portions may and expandable part is provided with clamping device, is distributed with aperture on the described net sheet.
Described net sheet has the elasticity that keeps stretched flat when not receiving external force constraint.
Described net sheet adopts plastic material to process.
Described clamping device is a clip.
Described aperture evenly distributes on the net sheet.
Beneficial effect
The utility model can solve the problem that cuts one another's throat in the crayfish culture process; Reduced the probability that the crab class cuts one another's throat; Also avoided simultaneously danger because of the injured introduced disease that cuts one another's throat; Thereby significantly improve the survival rate of crayfish culture, apparatus structure is reasonable and succinct, cost is low, easy to operate, practical, has broad application prospects.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1; The utility model comprises net sheet, clamping device, and described net sheet one lateral bending is rolled into the cylindric of both ends open, and opposite side stretches naturally; Described net sheet cylindrical portions may 1 is provided with clamping device 3 with the junction of expandable part 2, is distributed with aperture on the described net sheet.
Described net sheet has the elasticity that keeps stretched flat when not receiving external force constraint.
Described net sheet adopts plastic material to process.
Described clamping device 3 is a clip.
Described aperture evenly distributes on the net sheet.
When the utility model uses, cylindrical portions may 1 aperture adjustment of net sheet is big or small to suitably, use the junction of clip then, thereby fix cylindrical portions may 1 at cylindrical portions may 1 and expandable part 2, its aperture is no longer changed.The masking device that regulates put into culture the pond, the crab of corresponding size just can climb into the inside of its cylindrical portions may 1, hidden when being used for rest or the protection institute during as shell, thus avoid other individual cannibalisations, the raising survival rate.Through a large amount of these devices of use, can improve the survival rate of crab class in the whole breed pond, help carrying out smoothly of breed activity, can be used for the breeding production or the scientific research experiment of crab class.
