In the 50+ years I have been bumming around in the woods, I have yet to make use of any fishing tackle.
Based on that, I'd say it is not needed, but then other's opinions will vary.
Agreed ...
Based on a lot of WI and a fair sampling of CO. and other places, most of which had fish if they had water ... same here.
But if I needed fish in a survival scenario, I sure wouldn't engage in anything even remotely resembling sport fishing, traps, spears, plant poison or best of all a spare hand grenade would do the trick. Well ... so would a half pound of carbide and it'd be quieter.
If I was fresh out of hand grenades, I'd carry some heavy line (which I do anyhow, but not for fishing) add some shot and some hooks and think trotline.
I just can't imagine starving while I tried to catch a fish on one line with one hook. As far as bait or lures go, I learned as a kid it's easier to feed 'em than fool 'em, bugs, worms, grubs whatever you find on site.
But, survival wise, you're probably further ahead eating the grubs instead of using them for fish bait, same with the worms and bugs.
The BOB implies, to me, the need for travel, either to get someplace fast or just to get away from where you're at, also fast. Given those imperatives anything resembling sport fishing seems contra-productive. Different story of course if traveling by water.
As always, JMHO, YMMV and that's fine too!
