Abstract
本实用新型公开了一种青蟹养殖装置。人工养殖时会因青蟹逃跑或同类之间相互争斗造成损失，本实用新型采用大网箱套小网箱，将大网箱通过固定杆固定在海边滩涂上的装置来养殖青蟹，每个小网箱里只养一只青蟹，青蟹与青蟹之间被小网箱隔开，使得青蟹无法逃跑也避免了青蟹之间互相打斗而伤残死亡。大网箱通过升降环与固定杆相连，随着潮水涨退而升降，使青蟹不会被涨潮带来的泥沙掩埋，而且还能捕捉到海水中的软体动物浮游生物作为食物。采用了本实用新型后，因为避免了青蟹相互钳斗，可以提高养殖密度，每亩滩涂可以养1000-1500只青蟹，收获400-500公斤青蟹/亩，最大限度地利用了滩涂资源，这样的养殖方式更便于管理，节约养殖成本，提高效益。
The utility model discloses a mud crab breeding device. During artificial breeding, losses may be caused by blue crabs escaping or fighting among the same kind. The utility model adopts a large net cage with a small net cage, and the large net cage is fixed on a device on the beach by a fixed rod to breed blue crabs. Only one blue crab is raised in the small net cage, and the blue crab is separated from the blue crab by the small net cage, which makes it impossible for the blue crab to escape and prevents the blue crab from fighting with each other and causing disability and death. The large net cage is connected with the fixed rod through the lifting ring, and rises and falls with the tide, so that the blue crab will not be buried by the sand brought by the high tide, and it can also catch the mollusk plankton in the seawater as food. After the utility model is adopted, the breeding density can be increased because mud crabs are avoided from fighting with each other, and 1000-1500 mud crabs can be raised per mu of mud flat, and 400-500 kg mud crabs/mu can be harvested, which maximizes the use of mud flat resources , such a breeding method is easier to manage, saves farming costs and improves efficiency.
Description
Technical field
The utility model relates to a kind of blue crab cultivation device, belongs to the marine aquaculture technical field.
Background technology
Mud crab is a kind of crab class of living in warm sea area bank, belongs to Portumidae, and common have Scylla paramamosain, mud crab, olive malachite crab, South Sea mud crab, purple chela mud crab several, and it is coastal extensively to be distributed in China Guangdong, Guangxi, Fujian, Taiwan, Zhejiang.The mud crab individuality is huge, and growth rate is fast, can grow to 200-250g after growing up to, and delicious meat is nutritious, is regarded as precious seafood, and the good reputation of marine genseng is arranged, and is a kind of important marine economy species that are suitable for propagating artificially of coastal area.Mud crab inhabits the mires that salinity is lower, tidewater is unimpeded, tidal range is bigger such as river mouth, inner bay, mangrove forest more, on the beach.The artificial cultivating method of coastal various places is varied, mainly contains that crab pond monoculture, pond are raised together with, the low height of dam net breed of beach etc., has all obtained better economic and social benefit.Mud crab is flesh-eater, the natural disposition ferociousness, fight mutually between similar when propagating artificially, especially in the shell process of mud crab, fierce fighting can take place, and mud crab all one's life is experienced 13 shells approximately, thus mud crab fight mutually make that the crab body is injured, mutilation even death are a difficult problem in the blue crab cultivation.Another problem in the blue crab cultivation is that mud crab is crossed the pond, cement pit is run away and caused damage.Therefore, how to avoid mud crab because run away, fight and cause damage needing the problem considered in the breeding process with regard to becoming.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of blue crab cultivation device, is used for culturing mud crab and especially prevents that at breeding process mud crab from runing away, fighting mutually.
The solution of above-mentioned technical problem is to have adopted following technical measures: a kind of blue crab cultivation device, mainly formed by fish culture net cage, dead lever, fish culture net cage comprises large cage and small-sized net cage, large cage is cuboid, both sides external or four sides fixedly have the foam floating block, large cage is other to be provided with 2 or 4 dead levers, and the limit for height projection is arranged at the dead lever top, and large cage links to each other with dead lever by lifting ring; Be provided with 1-10 small-sized net cage that is fixed on the large cage bottom in the large cage, small-sized net cage is that the length and width height is the tetragonal body of 28-35cm * 15-20cm * 15-20cm, and sizing grid is 0.5-1cm * 0.5-1cm.
Take the utility model of above-mentioned measure, adopt large cage cover small-sized net cage, and large cage cultured mud crab by the device that dead lever is fixed on the beach of seashore, only support a mud crab in each small-sized net cage, separated by small-sized net cage between mud crab and the mud crab, wounded or disabled dead with regard to having avoided fighting mutually between the mud crab like this, mud crab is placed in to be cultured in the small-sized net cage, also just can't run away again.Large cage links to each other with dead lever by lifting ring, and large cage can move back and lifting along with tidewater rises, and mud crab can not flooded by the silt that tidewater brings at the incoming tide, and can also capture mollusk plankton in the seawater as food.After having adopted the utility model, clamp bucket mutually because avoided mud crab, can improve cultivation density, every mu of beach can be supported 1000-1500 mud crab, and results 400-500 kilogram mud crab/mu has maximally utilised the beach resource, simultaneously such breeding way, be more convenient for managing, save aquaculture cost, increase the benefit.

Fig. 1 is the utility model structural representation Fig. 1.
Fig. 2 is the utility model structural representation Fig. 2.
Embodiment
As shown in Figure 1 and Figure 2, the utility model mainly is made of fish culture net cage, dead lever.Fish culture net cage is divided into large cage 2 and small-sized net cage 5.1-10 small-sized net cage 5 that is fixed on large cage 2 bottoms arranged in the large cage 2, each small-sized net cage 5 is the tetragonal body of 28-35cm * 15-20cm * 15-20cm, there is grid on small-sized net cage 5 surfaces, and sizing grid is 0.5-1cm * 0.5-1cm, and each small-sized net cage 5 is cultured a mud crab separately.Large cage 2 is tetragonal body, be slightly larger than small-sized net cage 5, the interval of large cage 2 fence 4 is littler than small-sized net cage 5, and small-sized net cage 5 can not be spun off between the fence 4 of large cage 2, and large cage 2 outer surface both sides or four sides fixedly have foam floating block 6, large cage 2 is outside equipped with the dead lever 1 of two or four symmetries, link to each other with dead lever 1 by lifting ring 3, lifting ring 3 one ends and large cage 2 are fixing, and the other end is ring-type, slightly larger in diameter is enclosed within on the dead lever 1 in dead lever 1 diameter.Dead lever 1 bottom is sharp-pointed, and a limit for height projection 7 is arranged at the top.
Dead lever 1 inserts in the beach, and large cage 2 is fixed on the original place.When high tide, large cage 2 outer foam floating blocks 6 are subjected to buoyancy, driving large cage 2 upwards floats along dead lever 1, after floating to certain altitude on the large cage 2, can run into the limit for height projection 7 at dead lever 1 top and stop come-up, large cage 2 can not cause mud crab to be buried by the silt that flood tide brings owing to float, do not float because the restriction of limit for height projection 7 can not break away from dead lever 1, and this moment, mud crab was food with the plankton in the seawater; After the seawater ebb, large cage 2 drops on the beach along dead lever 1, and this moment, mud crab was food with the atom on the beach.
