Jews should know how to hunt and survive outdoors as a basic survival skill.
Catching food isn't as difficult as knowing what to do with it.
I don't hunt. I love guns (I guess owning five assault rifles qualifies as loving guns ;-) and I love shooting, but I've never hunted because I think it's cruel. Same reason I only buy free-range meats (or Kosher meats).
If suddenly there was a major breakdown in civilization, I would have little trouble hunting...I'm a good shot and there is plenty of wildlife around here (ducks, birds, etc.) In the woods, it's tougher because deer, elk, etc. are more at home - there are hunters who go out some years and never get anything. But really, modern technology is a huge advantage to the human, and if it was a crisis situation and there were no game laws, finding something to kill would not be the hard part.
The hard part is knowing what to do with it. Have you ever skinned a deer? I know the theory, but I've never done it. Do you know how to preserve the meat? Otherwise you're going to have one or two nice meals (well...venison is not exactly
nice) and then a lot of waste.
Same thing with fish. Harder to catch if you don't know what you're doing, and again, how many of us have prepped a fish to eat?
I hope it never comes to that.
