Description
Technical Field
The utility model relates to a breeding device technical field specifically is a crab seedling breeding device of mangrove wetland.
Background
Wetland, called "kidney of the earth", broadly refers to coastal areas temporarily or long-term covering low lands with water depth not more than 2 meters, meadows with more water filled in soil, coastal areas with water depth not more than 6 meters at low tide, including various saltwater and freshwater marshes, wet meadows, lakes, rivers, flood plains, estuarine delta, peat lands, lake and sea beaches, riverside lands or floods, wet grasslands, etc., the soft soil and vegetation of the wetland are natural filters, the speed of the water flow is reduced, when the water flow containing toxicants and impurities (such as pesticides, domestic sewage, industrial emissions, etc.) passes through the wetland, the flow rate is reduced to facilitate the precipitation and removal of the toxicants and impurities, the wetland is relatively suitable for plant growth due to long-term moistening, therefore, the wetland has a strong material production function, the wetland is internally stored with abundant animal and plant resources, is a complex and diverse plant, and community provides habitation for wild animals, especially for some rare or endangered wild animals, this makes the wetland become a vigorous natural paradise. Meanwhile, the wetland contributes much to the ecological environment, and can store water, adjust river runoff, supply underground water and maintain regional water balance.
The mangrove wetland is a special marine wetland type with mangrove plant communities as the core, the mangrove wetland ecosystem has distinct characteristics, has both land and marine ecological characteristics, is an ecological transition area between land and sea, has rich animal and plant resources, but causes water eutrophication, soil acidification and other forms of pollution of the wetland along with the influences of water pollution, air pollution, unreasonable land development and utilization of human beings and the like, and seriously damages the ecological environment of the wetland, so the protection and restoration of the wetland are not slow enough.
The crabs are crustaceans and are also a kind of organism in a mangrove wetland system, and are placed in the wetland after the young crabs are cultured to a certain degree, so that the crabs are one of the measures for wetland restoration, the crabs are placed in the wetland to provide food for birds, particularly migratory birds, and the crabs are natural enemies of collective water lice (mangrove pests). The number of benthos is increased by the homing of crabs, benthos chains in intertidal zones of the mangrove wetland are enriched, and the ecological balance in a wetland area is maintained, but the crab seedling culture device for the mangrove wetland is less at present and has low applicability, so that the research and development of the crab seedling culture device suitable for the mangrove wetland is the key for solving the problem.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the crab seedling culturing device is suitable for culturing crab seedlings in the mangrove wetland, and is simple in structure and high in survival rate.
The utility model adopts the technical proposal that: the crab seedling culturing device comprises a fixed stand column and a culturing floating body, wherein the culturing floating body is movably connected to the fixed stand column from top to bottom, the culturing floating body is a floating body with a cavity arranged therein, a partition plate which is divided into an upper layer and a lower layer is arranged in the floating body, the partition plate and the inner wall of the floating body are spaced and detachably connected to the inner wall of the floating body, the side wall of the upper part of the floating body is hollow, a gland is arranged at the upper end of the floating body, the lower part of the floating body is a culturing area, and the lower end of the culturing area. Preferably, the partition plate is arranged at the 1/4-3/5 of the height of the culture floating body.
Preferably, the hollow part of the culture floating body starts from the height of the floating body at 1/5-2/5.
Preferably, the meshes of the hollow parts are 2-4 cm multiplied by 2-4 cm.
Preferably, the mesh of the screen is 1 to 3cm × 1 to 3 cm.
After the structure more than adopting, the utility model discloses crab seedling breeding device passes through the stationary mast to be fixed in the wetland, breeds the body and can reciprocate at the stationary mast along with the lift of water level, and the crab seedling is bred in the lower part of breeding the body, can be in whole body internalization, can be used for placing the food of feeding the food on the baffle, also can be used for the active region of crab, the utility model discloses simple structure, the flexibility is strong, is applicable to the mangrove wetland to the survival rate is high.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a fixed upright post, 2, a breeding floating body, 3, a gland, 4, a clapboard, 5, a screen, 6, a movable sleeve, 7 and a limiting block.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the utility model discloses crab seedling breeding device, including stationary mast 1 and breed body 2, it is provided with the movable sleeve 6 to breed body 2 one side, movable sleeve 6 cup joints on stationary mast 1, it can move about on stationary mast 1 about to make breed body 2, it is the body of similar tubbiness structure to breed body 2, establish the cavity in, can float in the surface of water when rising tide, and be the suspension, be provided with in the body and separate into upper and lower two-layer baffle 4 with the cavity, baffle 4 has the interval and can dismantle through the buckle and connect on the inner wall of body, the lateral wall on body upper portion is the fretwork, the body upper end sets up gland 3, the lower part of body is the breed district, the breed district lower extreme sets up screen cloth 5.
The utility model discloses when concrete implementation, baffle 4 is less than rather than the size of the 2 internal diameters of the body of breeding of being connected, has the interval between the two, and the crab of being convenient for goes up to baffle 4 from breeding the district, and 4 edges of baffle are provided with the fixture block, and the activity joint is on the inner wall of breeding body 2, and baffle 4 sets up in 1/4 departments of breeding body 2 height, and the fretwork part of breeding body 2 begins from 1/5 departments of body height. The height here is measured from the lower end of the culture float 2. The mesh of the hollow is 2cm multiplied by 2cm, and the mesh of the screen is 1cm multiplied by 1 cm.
The utility model discloses when specifically using, fixing at the wetland through stationary mast 1, the setting of stationary mast 1 upper end is used for the restriction to breed stopper 7 of body 2, and the body cavity in is put into through the gland of breeding body 2 to the crab seedling, and the crab can be at breeding body 2 internalization, and the food of feeding can be placed on baffle 4, also can be used for the active region of crab, the utility model discloses when the wetland tide rise, water passes through in the fretwork admission apparatus, and the bait of aquatic can be shelved on the baffle when the tide falls, and the suspension when the preparation of breeding body 2 will satisfy the tide rise, and the part is soaked in promptly. The lower end of the cultivation floating body 2 is provided with a screen, and the residues and excrement eaten by crabs can be discharged through the screen because the floating body is suspended in water during the tidal surge, and simultaneously, the cleanness of a cultivation area is kept. And the water flow automatically washes and cleans automatically.
