Deep sea fishing involves catching fish in the open ocean, typically at least 30 meters (100 feet) deep. This type of fishing targets larger species such as tuna, swordfish, and shark, which are not usually found in shallower waters. Fishermen often use specialized boats and equipment, including heavy-duty rods and reels, to handle the size and strength of these fish. The practice can be done for commercial purposes or as a recreational activity. Many anglers enjoy the thrill of deep sea fishing, as it offers the chance to catch big fish and experience the vastness of the ocean. Safety measures, such as life jackets and communication devices, are essential during these trips.
