For a long term survival SHTF situation, fishing should not be overlooked. But to be able to fish, your going to need to have some basic fishing gear. As I have said in several forum post about stockpiling survival gear for SHTF, I think fishing supplies should be at the top of the list. That is, unless you live in a desert or hundreds of miles from a water source. In some kind of long term SHTF survival situation, fishing could be an important food source. The better prepared you are to utilize fish as a food source, the better your chances for success.
