50 50 is appropriate...you are half right! Lol
Trolling and trawling are BOTH fishing terms.
Trawling involves dragging a net catching all and sundry.
Trolling involves dragging a baited hook or lure hoping that a target will take the bait.
Number two is what is described on the net....but the results are often similar to number 1, with a lot of bycatch....
