Abstract
The utility model relates to a cylindrical porous shielding device for crab culture. The cylindrical porous shielding device comprises a shielding device body, wherein the shielding device body takes the shape of a cylinder with two open ends, and a plurality of small holes are distributed on the side wall of the shielding device body. The shielding device can provide a shelter for crabs during crab culture process, reduces the probability of contact among the crabs, reduces the probability of mutual killing of crabs, prevents the crabs from being infected by diseases after the crabs are hurt during mutual killing, remarkably improves the survival rate of the crab culture and facilitates an increase of culture density. The cylindrical porous shielding device has the advantages of reasonable and concise structure, low cost, convenience in operation, high practicality and broad application prospect.
Description
Technical field
The utility model belongs to technical field of aquaculture, particularly relates to a kind of cylindric porous 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 porous crayfish culture masking device; Can the place of covering be provided in the crayfish culture process, for the crab class; Reduce the probability that they are in contact with one another, thereby reduce the probability that the crab class cuts one another's throat, also avoided danger simultaneously because of the injured introduced disease that cuts one another's throat; Significantly improve the survival rate of crayfish culture, help increasing cultivation density.
The utility model solves the technical scheme that its technical problem adopted: a kind of cylindric porous crayfish culture masking device is provided; Comprise the masking device main body; Described masking device main body is the cylindric of both ends open, is distributed with some apertures on the described masking device body wall.
Described masking device main body adopts plastic material to process.
Described aperture evenly distributes on the masking device body wall.
Described aperture is circular.
Beneficial effect
The utility model provides the place of covering in the crayfish culture process, for the crab class; Reduce the probability that they are in contact with one another, thereby reduce the probability that the crab class cuts one another's throat, also avoided danger simultaneously because of the injured introduced disease that cuts one another's throat; Significantly improve the survival rate of crayfish culture; Help increasing cultivation density, apparatus structure is reasonable and succinct, cost is low, easy to operate, practical, has broad application prospects.
Description of drawings
Fig. 1 is the utility model structural representation;
1. masking device main body 2. apertures
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 masking device main body 1, and described masking device main body 1 is the cylindric of both ends open, is distributed with some apertures 2 on described masking device main body 1 sidewall.
Described masking device main body 1 adopts plastic material to process.
Described aperture 2 evenly distributes on masking device main body 1 sidewall.
Described aperture 2 is circular.
When the utility model uses; In the whole input of this device culturing pool, horizontal positioned, the crab of culturing in the pond just can climb into its masking device main body 1 inside; Hidden when being used for rest or the protection institute during as shell; Thereby on physical space, isolate, avoid other individual cannibalisations, improve survival rate with other crabs.Aperture 2 on masking device main body 1 sidewall can make current freely pass through; Both can keep the exchange of water body in the masking device main body 1 and fresh; Make device integral body can not be moved because of the disturbance of current or rotate again, the impetus of step when this aperture 2 is can also be as crab movable simultaneously.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.
