Hello,
If your talking about survival fishing the best "lure" you can make while your out on the water would be the bugs you find in the area. When I was younger, I was into panfish fishing, after we ran out of earthworms we would dig up worms and find bugs. All you really need are some smaller hooks, split shot, and a bobber. I hooked into everything from bluegill to some larger bass. It works with trout just as well if your fishing a small brook or stream. When I go ultralight backpacking in an area I know Ill be able to fish I take a 7 foot 3 piece or 6 foot 2 piece ultralight rod, a 1500 or 2000 size reel with 4lbs mono, a few Kastmasters, some small spinnerbaits, powerworms and powerbait, small swivels, hooks, split shot, bobbers, and a few flies. I dont think you need anything real fancy or special. If your in a survival situation and around water the fish probably dont see much fishing pressure. If your just doing it for fun its great practice and a lot of fun. PM me if you want to do a little fishing talk, its one of my passions.
Have a good one,
Chris
