When fish swim from all directions, small fish smaller than 3cm can pass through the stainless steel upright strips, fish larger than 3cm need to enter from the one-way fish inlet 110, and the large fish are trapped in the fishing net cage 100 after entering the fishing net cage 100. When a certain amount of fish is caught, a worker can select the fish in the fishing device, and the unwanted varieties are manually picked out. Since the current flooded fish breeds are introduced for keeping ecological balance, if all the current flooded fish breeds are caught, ecological imbalance is caused by completely stopping the current flooded fish breeds in the near future, so that other breeds needing to be bred are bred through the breeding hole 120 for ecological balance.
In summary, the ecological balance selective fishing device has the beneficial effects that:
(1) According to the ecological balance selective fishing device, the one-way fish inlet is arranged on the side face of the fishing net cage, so that large fishes outside the fishing net cage are easy to enter and difficult to exit, after the large fishes entering the fishing net cage are manually treated to remove unfavorable fish seeds for ecological balance, other favorable fish seeds are released through the releasing opening, and the like.
(2) Furthermore, the ecological balance selective fishing device disclosed by the invention is camouflaged into natural environment through the elastic pieces and the waterweed-like thin strips, so that the vigilance of fish can be reduced to a certain extent, when the fish wants to enter the fishing net cage to eat baits, the size of the fish body exceeds the size of a reserved opening in the unidirectional fish inlet, the fish body can be extruded between the elastic pieces and the waterweed-like thin strips, at the moment, the fish inlet formed by the two-row elastic piece groups in the shape of an out-splayed figure and the waterweed-like thin strips cannot block the fish, and in the process of entering the fish inwards, the elastic pieces and the waterweed-like thin strips bend towards two sides in the fishing net cage under the action of the extrusion force, so that the fish can smoothly and completely enter the fishing net cage, and the elastic pieces and the waterweed-like thin strips can be restored to the original positions due to the loss of the extrusion force generated by the extrusion of the fish, so that the fish is trapped in the fishing net cage is achieved.
Although terms indicating structures such as "fishing net cage", "one-way fish entrance", "reproducing entrance" and the like are used more above, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the invention; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present invention.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention.
