The old saying is fishing is the hardest way to get food in a survival situation and while this may be true if you are trying to catch them with your hands, its easy if you have a fishing pole.
When you are in a survival situation you're not going to be going after trophy bass, you'll be after any fish that will take the hook. Now for the rod and reel; an icefishing combo. I have a Berkley ice fishing combo that is just the right size to fit in my pack. You no longer have to dread fishing if you are in a survival situation.
