From the January 26, 2018 IPHC News Release:
The IPHC did not agree on new Pacific halibut catch limits for 2018, and therefore the catch limits adopted by the IPHC in 2017 remain in place. Both Contracting Parties, Canada and the United States of America, indicated their intention to pursue lower catch limits for 2018 via domestic regulatory processes.
The IPHC approved a fishing period (season) of 24 March – 7 November 2018 for the Canadian and U.S. quota-share fisheries. The treaty tribal commercial fisheries and the incidental Pacific halibut fisheries in IPHC Regulatory Area 2A will occur within these dates. In IPHC Regulatory Area 2A, seven 10-hour fishing periods for the non-treaty directed commercial fishery are recommended: 27 June, 11 July, 25 July, 8 August, 22 August, 5 September, and 19 September 2018.
