Don't forget trapping isn't a good way to gather food while on the move. You need to set a lot of traps (this takes time) and hope one catches something. Then before moving on you had better dismantle/trigger the traps. To not do so is a gross violation of nature's resources.

Fishing on the other hand will likely be more productive if you know what you are doing. Traps for fish, minnows, and crayfish are easy to make from natural materials or even trash. Minnows are good because you can eat the whole thing, nothing is wasted.

Another easy to catch, energy rich, plentiful, and suprisingly tastey food source are bugs...

I think we'd all really like to know how much wilderness experience/practice you have.
