Found a pretty cool tutorial for tying fishing nets.
https://youtu.be/gfTWgMTqGqYGetting that much quality twine will be a challenge, but you could probably adapt it into a pre-collapse hobby. I, personally, am going to look into using his other video to make my own landing net and see about adapting this into a backyard hammock so it's at the ready when game wardens are no longer a problem.
Does anybody live in a place where dropnet fishing is legal, or have experience trolling nets? Which do you think is more effective on a non ICE ship?
