This study presents archeological evidence for the presence of adult T. thynnus, in waters off the west coast of British Columbia and northern Washington State for the past 5000 years. Skeletal remains of large bluefin tuna have been recovered from 13 archeological sites. Investigations indicate that bluefin tuna between at least 120 and 240 cm total length were successfully harvested by aboriginal hunters. Archeological evidence is augmented by the oral accounts of native aboriginal elders. Despite this information, there are no 20th-century records of adult bluefin tuna in the northeastern Pacific.
