Types of fishing vessels proceeding to the Pacific Ocean for fishing operation are categorized as tuna longline fishing vessels, tuna purse seine fishing vessels, and carriers of the Republic of China.

Fishing vessels proceeding to the Pacific Ocean to catch tunas, billfishes, sharks, skipjacks, or mahi mahi shall be limited to tuna longline fishing vessels of 20 Gross Tonnage (GT) and above or tuna purse seine fishing vessels.
“Regulations on the Management of Catching Pacific Bluefin Tuna” or “Regulations for Fishing Vessels Conducting Southern Bluefin Tuna Fishery” shall also be applied to any tuna longline fishing vessel catching Pacific bluefin tuna or southern bluefin tuna.

Tuna longling fishing vessels proceeding to the Pacific Ocean for fishing operation are categorized, in accordance with the catch species and operation patterns, into the following groups:
(1) Large scale longliners:
i. Bigeye tuna group: bigeye tuna as the target species.
ii. Albacore tuna group: albacore tuna as the target species.
(2) Small scale longliners:
i. Frozen yellowfin tuna group: a fishing vessel with freezing equipment which has more individual vessel quota of bigeye tuna than a fishing vessel of the general group.
ii. Seasonal sharks group: fishing vessels targeting sharks during certain seasons and whose individual vessel quota of bigeye tuna is less than fishing vessels of general group.
iii. General group: no specific target species.
Fishing areas in the Pacific Ocean for large scale longliners are divided as follows, and are as shown in Appendix 3 and 4:
(1) Bigeye tuna fishing area: the area west of 150°W and between 15°S to 20°N; and the area between 130°W to 150°W and 20°S to 25°N.
(2) North bigeye tuna fishing area: the area between 130°W to 150°W and 25°N to 40°N.
(3) East bigeye tuna fishing area: the area east of 130°W and between 20°S to 20°N
(4) Albacore tuna fishing area: the area between the west of 130°W and the south of 10°S; and the area between the east of 130°W and the south of 15°S.
(5) North albacore tuna fishing area: the area between the west of 130°W and the north of 10°N; and the area between the east of 130°W and the north of 15°N.
Fishing areas in the Pacific Ocean for small scale longliners are divided as follows and are as shown in Appendix 5:
(1) Western and central Pacific fishing area: the area west of 150°W and north of 20°S.
(2) Eastern Pacific fishing area: the area between 130°W to 150°W and the south of 5°S and the north of 10°N; the area between the east of 130°W and the south of 15°S and the north of 10°N
(3) Eastern Pacific swordfish fishing area: the area between 130°W to 150°W and 5°S to 10°N.
(4) Southern Pacific fishing area: the area west of 150°W and south of 20°S.
The fishing area for tuna purse seine fishing vessels fishing in the Pacific Ocean shall be limited to the area west of 150°W, and such vessels shall not fish on the high seas north of 20°N or south of 20°S.
Catching vessels shall fish only within the fishing area(s) permitted by the competent authority.

ii. General group or seasonal sharks group: the total number of fishing vessels is limited to 550, among which the maximum number of fishing vessels of the seasonal sharks group is 170, and 150 since 2025. However, the number of fishing vessels fishing in the eastern Pacific fishing area and in the eastern Pacific swordfish fishing area shall be promulgated by the competent authority.

(2) Any tuna purse seine fishing vessel shall not stay at sea for more than three consecutive months.
The duration as referred to in the preceding paragraph may be extended for two months with the consent of the competent authority, provided that there is a cause of force majeure or insufficient berths in port that leads to catching vessels failing to enter port within the required timeframe. Such extension shall be permitted for one time only.
