Your post specifically said SPEAR hunting. You do not hunt small game with a spear. Trapping is usually the most effective way of getting meat in the wild.
Off topic but some of the best traps are large modern mouse-traps. Just make sure to drill a hole and tie it to a tree with a strong rope so the animal doesn't pull it away. Set it, and you will almost certainly capture a small mammal within a day.
