I would definitely depend on hunting to supplement my stores. As already mentioned by others, there are plenty of Squirrels, a few Raccoons, & a few Rabbits that reside in my neighborhood. There are also Robins, Blackbirds, and Doves in this neighborhood. Thats why I have a .177cal air pump rifle, w/a scope, AND 5000 pellets AND 3000 BB's for it.

I would have to scout around some (which I will now start doing) to find any ponds that may be near enough to fish. Right now, I don't know of any that are close enough to use except by bicycling and that would still be an all-day affair.
