[0034] A kind of realization mode of the technical scheme provided by the present invention is:
[0035] Such as figure 1 and figure 2 As shown, a semi-mechanized large-scale seafood fishing device is characterized in that it includes:
[0036]The net-spreading part includes a launching frame 2, which is an inverted trapezoidal frame body, and the middle part of the upper frame 9 of the launching frame protrudes to a direction at a certain angle with the plane where the launching frame is located to form an arc-shaped lifting part. The lower frame 12 of the launching frame is an arc-shaped frame protruding toward the upper frame direction, and the lower frame has a cavity with a polygonal cross-section extending along its length; at least two through holes are arranged at the lower end in parallel and spaced apart. On the side wall of the frame, the cavity communicates with the outside world, and the opening direction of at least two through holes is consistent with the arc...
