Spearfishing is a method of fishing that involves using a spear or a specialized spear gun to catch fish underwater. This technique can be practiced while free diving or scuba diving, allowing the fisherman to target specific species. It is often considered a sustainable fishing practice because it allows for selective harvesting, reducing the chances of overfishing. The practice of spearfishing requires skill and knowledge of marine environments, as well as an understanding of local regulations regarding fishing. Many spearfishers use wetsuits and fins to enhance their mobility in the water. Safety is also a key consideration, as divers must be aware of their surroundings and potential hazards, such as strong currents or marine life.
