Four types of hooks–J-style, tuna hook, tuna 18 offset and circle hooks–were tested on pelagic loglines fishing close to Mazatlan Mexico to determine their effectiveness at catching sharks and other pelagic species.  Circle hooks had the highest catch rates for the principal target species, blue and striped marlin.
