>>2168930>it's hard to rely on hunting as a source of food.Probably because with a grade school backpack you cannot carry the equipment you need for hunting and fishing, it's not just to waste money that professionals buy fishing backpacks or bags. You've to adapt to the environment because the environment won't adapt to you and you cannot expect to be able to fish with the same equipment everywhere, you've to account for (1) your available time and (2) the kind of fish that lurks there.
The cheapest freshwater fish goes from 10 euros/kg in my region, catching your own will save you tons of money over time, fish provides fats and protein with some calcium as well, if you're camping somewhere near a river or lake it would be beyond retarded to not give fishing a try and fishing equipment is cheap as shit if you know where to look.
