Referring to fig. 1, the present invention mainly provides that the fishing net N has the net wall 10 and the net bottom 20, the movable lower edge section 112 of the net wall 10 is connected to the net bottom 20, the movable upper edge section 111 of the net wall 10 is connected to the upper edge net rope 30 and the upper edge weight 31, the upper edge weight 31 normally provides a force along the direction a to the movable upper edge section 111, the movable upper edge section 111 normally approaches the movable lower edge section 112, and the opening O is formed between the movable upper edge section 111 and the fish raft P, so that fish schools can enter the fishing net N through the opening O, and after enough fish schools swim into the fishing net N, referring to fig. 4, a user can drive the upper edge net rope 30 to move, so that the movable upper edge section 111 moves away from the movable lower edge section 112 and approaches the fish raft P to close and stay at the opening O, and fish schools between the net wall 10 and the net bottom 20.
In addition, referring to fig. 5, the movable lower edge section 112 of the net wall 10 is connected to the lower edge net rope 40 and the lower edge weight 41, when a fish school stays between the net wall 10 and the net bottom 20, a user drives the lower edge net rope 40 to move, so that the movable lower edge section 112 is also close to the fish raft P to drive the net bottom 20 to be close to the fish raft P, and further, the captured fish is pushed upwards and upwards towards the fish raft P, so that a fisherman can capture the fish more conveniently, and the chance of fish escaping when the net is retracted can be reduced.
Therefore, the user can conveniently unfold, fold and store the fishing net N, and the fishing net N can be suitable for different environments of a fish pond, offshore or ocean, and can prevent the fishing net N from being deformed by sea waves to the maximum extent, thereby achieving the effects of effective application and obtaining better economic benefits.
Although the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
