Spearfishing is a form of fishing that has been popular throughout the world for centuries. Early civilizations are familiar with the custom of spearing fish out of rivers and streams using sharpened sticks as a means of catching food.
Spearfishing may be done using free-diving, snorkeling, or scuba diving techniques. However, spearfishing while using SCUBA or other artificial breathing apparatus is frowned upon in some locations and is illegal in many others. Because of the lack of sport in some modern spearfishing techniques, the use of mechanically-powered spearguns is outlawed in some jurisdictions.
