I just saw an r/oddlysatisfying video of a guy throwing a giant fishing net in slow motion and it occurred to me that I don’t know how they work. Like I see how throwing it spreads it out but how do fish actually get trapped in a flat net? Is there some mechanism that closes it up?
In: Technology
the net have heavy chain on the outer layer. when you throw net in water, heavy chain go bottom and fish inside net cannot escape. then you pull it, fish trapped inside
the edges are weighted down, so the net just falls to the bottom, and then the fisher man reels it back up. and a bunch of fish are caught inside of it. [https://www.youtube.com/watch?v=Pchtdyhv0ok](https://www.youtube.com/watch?v=Pchtdyhv0ok)
Depends on the type of net. Salmon are caught in a vertical net that has a lead line through the bottom. They swim into the holes of the net and get stuck. Fisherman actually change the sizes of the holes in the net depending on how large the fish are they are catching or not catching.
