Title 16 › CHAPTER 31 — MARINE MAMMAL PROTECTION › SUBCHAPTER IV — INTERNATIONAL DOLPHIN CONSERVATION PROGRAM › § 1413
The Secretary must make and update rules to carry out the International Dolphin Conservation Program. The rules will let and control how U.S. vessels may take marine mammals in the eastern tropical Pacific Ocean, including species listed as depleted but not as endangered or threatened. Rules must require an observer on each vessel, use of the backdown method or an equally effective way to avoid killing or badly injuring marine mammals, and completion of the backdown and start of rolling the net to sack up no later than 30 minutes before sundown. They must ban intentional sets on dolphin schools and the use of explosives in purse seine fishing. The rules will set per-vessel, total, and per-stock annual dolphin mortality limits and stop vessels from fishing on dolphins after limits are reached or from fishing on dolphins without an assigned limit. The rules also require special gear (for example, dolphin safety panels, monitoring devices to spot unsafe conditions, working rafts and speedboats with towing bridles, working floodlights, and masks and snorkels), allow limited experimental fishing to test safer methods that do not encircle dolphins, and may let vessels fish without special gear if they carry an observer and do not intentionally encircle dolphins. The Secretary may adjust gear and practice rules as long as they remain consistent with the international program. When making rules, the Secretary must consult the Secretary of State, the Marine Mammal Commission, and the U.S. Commissioners to the Inter‑American Tropical Tuna Commission. If the best scientific information shows that incidental dolphin mortality or serious injury is having or will likely have a significant harmful effect on a stock or species, the Secretary must notify the Commission with recommendations and issue emergency rules to reduce and fix the harm, after consulting the same parties. Emergency rules must be published with an explanation, stay in effect for the fishing year (but can be ended sooner), and may be extended if harm continues in the yellowfin tuna fishery in the eastern tropical Pacific. Within 120 days after the Secretary’s notice, the U.S. Commissioners must call a special Commission meeting and report in writing to the Secretary and Secretary of State on what actions were taken, whether they were enough, and any extra steps needed.
