Code of Federal Regulations Title 50. Wildlife and Fisheries § 50.300.174 Logbook reports

The owner of any U.S. vessel that fishes for albacore tuna in Canadian waters under the Treaty as amended in 2002 must maintain and submit to the Regional Administrator a logbook of catch and effort of such fishing. The logbook form will be provided to the vessel owner as soon as practicable after the request to be placed on the list of vessels. The logbook must be submitted to the Regional Administrator within 15 days of the end of a trip, regardless of whether the trip ends by reentry to U.S. waters or entry to Canada's territorial sea, other Canadian waters in which fishing is not permitted, or a Canadian port. If the departure is due to exit to the high seas, the vessel operator must submit the logbook within 7 days of its next landing.
