Description

Cage device for trapping fish by light on large water surface lamp

Technical Field

The invention relates to the field of cage devices, in particular to a cage device for trapping fishes by light of a large water surface lamp.

Background

The large water surface includes water bodies such as reservoirs, lakes and the like. The core of the present large water surface is to reasonably utilize the bait resources of different groups of water bodies on the premise of determining the increasing and cultivating capacity to convert the nutrient substances of the water bodies into high-quality aquatic products, thereby achieving the purpose of 'cultivating water in fish'. Therefore, controlling the number of fish in different nutrition levels on large water surfaces is a key to implementing ecological fishery.

Culter ilishaeformis (Culter alburnus), commonly known as whitefish, belongs to the families of cyprinidae, subfamilies, culter, and is a small fish on the middle and upper layers of welts. Although the natural river has the phenomenon of declining resource quantity, in large water surface water bodies such as reservoirs and the like, the natural enemy is not present, the bait resource is rich, and the culter ilishaeformis forms an dominant population in a plurality of reservoirs such as three gorges reservoirs, five strong streams reservoirs and the like. The predatory fishes are dominant in number, which is unfavorable for developing ecological fishery in large water surface water bodies, and the number of silver carp fries and other small fishes in reservoirs can be influenced. Therefore, the large water surface water body needs to perform directional fishing on the culter ilishaeformis which form the advantage.

The existing fishing devices on large water surfaces such as reservoirs are basically used for fishing by adopting a combined fishing method of blocking thorns and blocking thorns, and the fishing mode is mainly used for fishing large-size fishes such as silver carps and bighead carps of reservoirs, and is the most famous for fishing by using huge nets of Qiandao lakes; other fishing modes are mainly based on the flow-stabbed net, the fishing efficiency is too low, no screening is carried out, no targeted fishing is carried out, other fishes are easy to catch, meanwhile, the later-stage sorting workload is large, in the fishing process, the fishes are easy to escape due to the fact that the fishing mode is not adopted, the firmness of the fishing net is too poor, and the fishing net is not suitable for long-term fishing. Therefore, development of a special fishing net suitable for carnivorous fishes such as culter ilishaeformis on the large water surface is needed.

Disclosure of Invention

The invention aims to solve the problems in the background technology and provides a net cage device for trapping fishes by using a large water surface lamp light.

The technical aim of the invention is realized by the following technical scheme:

the utility model provides a big fish cage device is traped to surface of water lamp light, includes the trapping layer and establishes the collecting layer in trapping layer bottom, the trapping layer is including inside hollow trapping shell, bottom plate, rotatory apron, arc division board, arc drive the board, trap the lamp, the bottom plate is established the bottom of trapping shell and with the inside wall fixed connection of trapping shell, the crowd collecting port has been seted up at the middle part of bottom plate, a plurality of crowd entry has been seted up on the lateral wall of trapping shell, the crowd entry is circumference equipartition on the lateral wall of trapping shell, the arc division board is circumference equipartition on the top surface of bottom plate, is equipped with one between every two adjacent arc division boards the crowd entry, rotatory apron is established the top opening part of trapping shell, the arc is driven the board and is established the bottom of rotatory apron, the arc direction of driving the board with the arc direction of opening of arc division board is relative, the lamp is established the middle part of bottom plate. The phototactic of fish such as culter ilishaeformis is utilized through the light that the trap lamp gives off, lure the fish of phototactic to the trapping layer, the culter ilishaeformis that the trapping that can the biggest dynamics is to the perk, the pertinence is stronger, later get into to trapping the casing through the crowd entry, rotatory apron slowly rotates, it is rotatory to drive the arc and drive the board, in the rotatory in-process, make the arc drive board and arc division board form enclosure space, because the arc drive the board always be rotatory, make enclosure space reduce gradually, make the fish get into the crowd and collect the mouth, later collect in the collecting layer, later carry out artifical letter sorting with the fish of fishing, can catch a large amount of culter ilishaeformis, make when the culter ilishaeformis breeds in the perk, prevent that the perk mouth from forming the dominant population, the survival rate to the reservoir and other small-size fish produces the influence.

Because the arc drives the slow rotation of board for the arc drives the enclosure space that board and arc division board formed and can slowly reduce, can not produce the frightening to the fish thereby improves and catches efficiency.

The trapping layer of present case top, the collecting layer is in the below for the fish after entering into the trapping layer can't escape, make the collecting layer area of collecting the fish bigger, can once only catch more fish, improve and catch efficiency.
