Abstract

The utility model discloses a suspended pebble fish egg attachment base. The suspended pebble fish egg attachment base is characterized in that a hook is arranged at the upper end of an attachment base body, the lower portion of the hook is connected with a suspension rope, the lower end of the suspension tope is branched to be divided into two suspension branch ropes, the lower ends of the suspension branch ropes are tied to the two ends of a suspension shaft, the suspension shaft penetrates through a PVC pipe, the diameter of the PVC pipe is 10 cm, the length of the PVC pipe ranges from 50 cm to 100 cm, a layer of pebbles is laid on the outer wall of the PVC pipe, the diameter of each pebble ranges from 3 cm to 8 cm, and the outer side of the layer of pebbles is wrapped and fixed in a polyethylene net with the mesh size ranging from 1.5 cm to 2.5 cm. When the suspended pebble fish egg attachment base is in use, in the fish breeding season, the suspended pebble fish egg attachment base is suspended in a water body, eggs laid by fishes are directly attached to the pebbles, the attachment base pebble area is large, and more fish eggs can be attached to the suspended pebble fish egg attachment base; moreover, the suspended pebble fish egg attachment base is away from the water bottom, and located in the middle of the water body, the water body exchange conditions are good, the fish eggs are not prone to oxygen shortage, and hatchability of the fish eggs can be improved.

Description

Suspension type gravel fish-egg adherance

Technical field

The utility model relates to fish production field, specifically suspension type gravel fish-egg adherance.

Background technology

The fish happinesses such as the thin oblique volume silver xenocypris of squama, loach, meal bar fish are laid eggs on gravel, and because gravel is sunken to the bottom, fish-egg bond area is limited, and gravel is easy to anoxic under Lentic environment condition, have affected the incubation rate that adheres to fish-egg.

Summary of the invention

For overcoming above-mentioned defect, the utility model has designed suspension type gravel fish-egg adherance.

The technical solution of the utility model is that suspension type gravel fish-egg adherance, is characterized in that, adherance upper end is hook, and hook below connects suspension rope, suspension rope lower end branch, be divided into two suspention branch lines, suspention branch line lower end lies in respectively the two ends of suspention axle, and suspention axle passes in the middle of pvc pipe, 10 centimetres of pvc pipe diameters, long 50-100 centimetre, at outer wall tiling one deck gravel of pvc pipe, gravel diameter 3-8 centimetre, gravel outside adopts the polythene net sheet of 1.5-2.5 centimetre of mesh to wrap.

Beneficial effect: use the utility model suspension type gravel fish-egg adherance, in fish reproduction season, adherance is hung in water body, and fish lay eggs and directly invest on gravel, and adherance gravel area is larger, be conducive to adhere to more fish, and at the bottom of adherance leaving water, be positioned at water body middle level, water body give-and-take conditions are good, be difficult for anoxic, can improve hatch fish roe rate.

Accompanying drawing explanation

Fig. 1 is the utility model structure chart.

In figure: 1 hook, 2 suspension ropes, 3 suspention branch lines, 4 gravels, 5 polythene net sheets, 6 suspention axles, 7 pvc pipes.

Embodiment

Accompanying drawings the utility model, suspension type gravel fish-egg adherance, it is characterized in that, adherance upper end is hook 1, link up with 1 below and connect suspension rope 2, suspension rope 2 lower end branches, be divided into two suspention branch lines 3, suspention branch line 3 lower ends lie in respectively the two ends of suspention axle 6, and suspention axle 6 passes in the middle of pvc pipe 7,10 centimetres of pvc pipe 7 diameters, long 100 centimetres, at outer wall tiling one deck gravel 4 of pvc pipe 7, gravel 4 diameter 3-8 centimetre, gravel 4 outsides adopt the polythene net sheet 5 of 2.5 centimetres of meshes to wrap; Use the utility model suspension type gravel fish-egg adherance, in fish reproduction season, adherance is hung in water body, and fish lay eggs and directly invest on gravel 4, and adherance gravel area is larger, be conducive to adhere to more fish, and at the bottom of adherance leaving water, be positioned at water body middle level, water body give-and-take conditions are good, be difficult for anoxic, can improve hatch fish roe rate.
