When I am out for a long time, I carry small, light net, 5x5 feet.
It can be used to catch bait fish, eating fish, and birds.

A Conebear trap is light and will kill squirrels and rabbits instantly.

I always carry some fishing tackle. Mono, but also some 30-lb Spiderwire. No time for sport.

I also make my own snares from black nylon coated stainless steel saltwater wire fishing leader, with a large swivel on one end, and a smaller one that will pass through it on the other end, for tying to a branch.
