There's an old adage: "If you want to stop catching fish, pick up a fly rod." Now I personally love flyfishing and sportfishing with artificial lures. But if my life depended on catching something to eat, I would use live bait if I could get it. A simple survival fishing kit consisting of a packet of a few fish hooks and sinkers and a coil of fishing line takes hardly any space and is all you need for natural bait fishing. Poles and floats can be improvised.
