• Entry to this fishery is limited to a maximum of 164 vessels.
• Permits and logbooks are required.
• Observers are required on all Hawaii-based longline vessels.
• NOAA Fisheries vessel monitoring system program requires longline boats to be equipped with a satellite transponder that provides real-time vessel position updates and tracks vessel movements.
• Longlines are prohibited in certain areas to protect endangered Hawaiian monk seals and reduce the potential for gear conflicts and localized stock depletion.
• Vessels operating under longline general permits must carry special gear to release incidentally hooked or entangled sea turtles.
• Fishing gear requirements apply to all Hawaii longline limited access permitted vessels. The requirements may change depending on type of fishing trip, location of fishing, and how the gear is set. An overview of gear requirements can be found here.

• These Commissions rely on the scientific advice of their staff and the analyses of the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific (ISC) to develop and adopt international resolutions for conservation and management measures.
• Working with the U.S. Department of State, NOAA Fisheries domestically implements these conservation and management measures.

• Marlin are primarily caught incidentally in pelagic longline commercial fisheries for tuna and swordfish. They are also a popular target fish for recreational fishermen.
• In 2019, commercial landings of Pacific blue marlin from the waters around Hawaii totaled more than 3.7 million pounds and were valued at more than $2.6 million, according to the NOAA Fisheries commercial fishing landings database.
• The Billfish Conservation Act, along with existing billfish regulations, prohibits the sale and commercial possession of billfish and billfish products. However, those that are caught in Hawaii and the Pacific Insular Areas (which includes American Samoa, Guam, and the Northern Mariana Islands) are exempt and can be sold.

• U.S. pelagic longline fishermen who target tuna and swordfish may incidentally catch blue marlin.
• Fishing gear used to catch tuna and swordfish rarely contacts the seafloor so habitat impacts are minimal.
• Restrictions on the type of fishing gear that can be used, and prohibitions on fishing in certain areas, minimize impacts on protected species.
• Interactions with protected species such as sea turtles, marine mammals, and seabirds in these fisheries are rare and survival rates are estimated to be high for all gear types.
• Longline fishermen are trained in safe handling and release techniques for sea turtles, seabirds, and marine mammals, and they carry and use specific equipment for handling and releasing these animals.
• Scientists and managers continue to monitor bycatch in these fisheries through logbooks and fishery observer programs.

• Blue marlin are a favorite target for recreational fishermen, as the fish tend to put up an incredible fight when hooked.
• In 2019, recreational anglers landed more than 1.8 million pounds of blue marlin, according to the NOAA Fisheries recreational fishing landings database.
• Hawaii hosts one of the largest billfish tournaments in the United States. Most fish caught in recreational tournaments are tagged and released.
• There is little bycatch associated with the recreational fishery.

According to the 2013 stock assessment, Pacific blue marlin are not overfished and not subject to overfishing. Summary stock assessment information can be found on Stock SMART.
