Technical field
The utility model is related to technical field of aquaculture equipment, relate generally to a kind of portable fish egg harvester.
Background technology
When carrying out aquatic science research, it is sometimes desirable to investigation and sampling is carried out to fish-egg, common progress viscous roes are adopted
Diversity method includes：（1）Directly fish for.For the fish that fish of the part with nest building behavior and parent are escorted, their fish
Ovum is distributed in nest shape, and the bed mud of bottom surface can be taken by mud dredger, carries out the direct counting of ovum.（2）Artificial fish nest.It is logical
Common water plant or palm silk are bundled into beam and are placed on the waters that hydrostatic or current delay, and attract fish oviposition, sometimes also by lake region
Place the attractions such as crannied crock production viscid egg species oviposition.
The sampling of fresh water rivers drift fish-egg generally uses brailer and Jianggang nets.Its characteristic of these netting gears can mainly divide
For two types, i.e. active netting gear and Fixed nets device.Brailer is easy to carry since network interface is small, is mainly used for the master of mobility
Dynamic sampling；Jianggang nets are then mainly arranged at fixed point and carry out fish-egg, prelarva sample collection.But Jianggang nets network interface is semicircle,
The installation of net is complex, and is unsuitable for quantitative interview.However, it is necessary to come according to demand when being acquired at present to fish-egg
Alternative one is selected, lacks a kind of device that can actively sample but also fix acquisition fish-egg.
Utility model content
The purpose of the utility model is to overcome deficiencies of the prior art, provide a kind of simple in structure, small, more work(
Energy, fish-egg harvester easy to use.
To solve the above-mentioned problems, there is provided a kind of portable fish egg acquisition dresses for the technical solution adopted in the utility model
It puts, including：Buoy, rope, fish-egg attachment base, egg-collecting box, the buoy are located at the upper end of rope, set are equipped with outside the rope
Pipe, described sleeve pipe are equipped with multiple fish-egg attachment bases, and the fish-egg attachment base includes stent and fish nest, the stent and set limb
Degree is adjustable in the range of 0-90 °, and the stent is arc-shaped and identical with cannula curve, and the stent is equipped with fish nest, described
Fish nest is removably to be connected with stent.Using the technical solution, the stent can both be collapsed and covered with casing in 0 degree
Guan Shang, and can open with casing at an angle, fish nest is placed, fish is facilitated to lay eggs.
The rope lower end is equipped with the egg-collecting box, and the egg-collecting box upper end is gauze, and the egg-collecting box lower end is entity
Water tank, the water tank bottom control water outlet to be closed equipped with water outlet and by switching, which is used to adopt when fish-egg
When acquisition means leave waters, the water in water tank is conducive to the survival of fish-egg.
Further, the rope upper end is equipped with the handle of surface anti-skidding, using the technical solution, is conveniently operated, and improves
Efficiency.
Further, described sleeve pipe top is latched equipped with hasp lock, and the handle is equipped with hasp locking and hanging hook, the handle
It can be fixedly connected with casing by hasp lock.By the technical solution, handle can be made to form fixed structure with casing, conveniently passed through
Handle operates egg-collecting box.
Further, described sleeve pipe lower end is equipped with current meter close to the position of egg-collecting box.It can be appreciated that by the technical solution
The water velocity at underwater egg-collecting box position.
Further, the fish nest is sea grass or polyethylene mesh sheet.
Further, the buoy 1 is removably to be connected with rope 2.
Further, 8 mesh size of gauze is less than fish-egg size.
Compared with prior art, the utility model portable fish egg harvester both can directly fish for the fish-egg in water,
Fish nest can be set to create fish reproduction environment to collect fish-egg again, be convenient for carrying, be easy to operate, when device leaves waters, water
The setting of case can be such that fish-egg keeps in the environment of moistening, beneficial to the survival of fish-egg.
