Spearfishing is a sport that involves a diver, usually on his own breath hold, ducking under the waves to hunt fish using a spear gun or pole spear. In Southern California, where I hail from, there are plenty of excellent places to dive that yield fun hunts. Before you get in the water though, there are many things you need to know, like where to dive, what gear to use, and how to dive safely. Always dive with a buddy!
