Description
Technical field
The utility model belongs to fishery technology, and in particular to a kind of artificial fish nest.
Background technique
Currently, water plant quantity largely reduces in the natural waters such as river,lake and reservior, is produced from the spawning ground of the fish of viscid egg
Institute's wretched insufficiency, and then decline the type and quantity that viscid egg fish are produced in water body sharply.In days such as river, lake, reservoirs
Artificial fish nest is set in right water body, fish oviposition effective area can be increased, water body fish population quantity is supplemented, alleviate fishery resources
With the decline of bio-diversity, restores aquatile population structure, improve the ecological environment in waters.
It is found in practice, existing artificial fish nest contact surface is small, and partial fertilization ovum is unevenly distributed, anoxic when causing to hatch
Death, partial fertilization ovum adhere to hypoxia death when fertilized eggs being caused to lose or hatch that unsuccessfully sinks under water.In addition, aquatic animal pair
Ingesting for fertilized eggs is also a key factor for influencing existing artificial fish nest hatching effect in fish nest.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of collection rate that can be improved fertilized eggs and hatching rate, and
The artificial fish nest of safe environment of hatching is stablized in building.
The technical solution that the utility model solves the problems, such as is：A kind of artificial fish nest, including boxed frame, frame roof can
The first permeable supporting body is equipped with the adhering substrate that can adhere to fish-egg on the first supporting body；
It is equipped with water-permeable second supporting body in base of frame, the second supporting body is equipped with ovum layer；
Openable and closable protective net is equipped in frame facet；
The frame, the first supporting body, the second supporting body, protective net, which surround, is assembled to form water-permeable closed housing.
In above scheme, ovum layer be used to accept from adhering substrate adherency unsuccessfully and the fish-egg that falls off.
By the barrier of protective net, fish and other aquatiles can be effectively prevent to ingest fertilized eggs, building is stablized
Safe environment of hatching, to improve the hatching rate of fertilized eggs.
Specifically, the boxed frame is hexahedron structure, first supporting body is to be arranged at intervals at frame roof
Connecting rope；
The adhering substrate is tied up by natural waterweeds, and is fixed in connecting rope.
Natural waterweeds materials are convenient, and blade scatters, and can make full use of the solid space of water body, effectively increase fertilized eggs
Adhered area, and then improve the collection rate and hatching rate of fertilized eggs.
Preferably, second supporting body is the stainless (steel) wire for being fixed on base of frame, and described the ovum layer is to be layed in not
The brown piece become rusty on steel mesh.
In a kind of specific scheme, the protective net is stainless steel mesh sheet, is respectively arranged at the four of hexahedron structure frame
A side；
Each stainless (steel) wire piece upper end correspondence is hinged with frame roof seamed edge, each stainless steel mesh sheet can be around respective
Hinge joint be flipped up.
In this kind of scheme, protective net is overturning opening mode.
In another specific scheme, it is equipped with the first slot on four inclines of hexahedron structure frame, in frame
The seamed edge of bottom surface is equipped with the second slot of notch upward；
It is inserted into the first slot per a piece of stainless (steel) wire piece from frame upper end, and takes advantage of a situation and be caught in the second slot and fix.
In this kind of scheme, protective net is to pull and push mode up and down.
Further, submerged plant is equipped in base of frame.The photosynthesis of submerged plant can provide institute in hatching process
Aerobic gas improves incubation condition, improves the hatching rate of fertilized eggs.After the fish egg-laying season, submerged plant can improve water body water
Matter and offer fish habitat place.
Further, float is installed on frame.The buoyancy that float generates can make in the suspension of fish nest and water body.
Preferably, hawser is connected on the frame, the hawser other end is equipped with grasp.
The remarkable result of the utility model is：
1. the fish Nest architecture for possessing adhering substrate and submerged plant can make full use of the solid space of water body, effectively increase by
Smart ovum adhered area, and then improve the collection rate and hatching rate of fertilized eggs.
2. the photosynthesis of submerged plant can provide required oxygen in hatching process, improve incubation condition, improves fertilized eggs
Hatching rate.After the fish egg-laying season, submerged plant can improve water quality and provide fish habitat place.
3. fish and other aquatiles can be effectively prevent to ingest fertilized eggs by the barrier of mesh sheet, building is stablized
Safe environment of hatching, to improve the hatching rate of fertilized eggs.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the utility model fish Nest architecture schematic diagram.
