Do you carry one in your survival kit, or is it excess baggage?

If you do carry one, lets see em! What do you have in it? I've got the basics... swivels, hooks, line, sinkers... but I seriously doubt I can catch much as I don't fish very often. I poke at crappie next to the shore, since that's all I generally have luck with (although I wouldn't know what to do with it if I caught it...)

For a survival situation, what do you guys think of something like a trout line, speed hook, gill nets or other specialty items? Most of it is too large for a pocket kit obviously... but being able to set a line and walk away from it, and check it daily would probably be more efficient time and energy wise than sitting on the bank fishing with a stick and line...

Speaking of that however, what kind of bait do you guys include? Gummy worms? Lures? Flies? or do you forgo anything other than a hook and rely on natural things you find in the area (live worms or insects)?
