    The Chinook species survived the Ice Age. Chinook are the largest of the Pacific salmon. The current record for a sport-caught Chinook is lbs (46 kg). The explorers Lewis and Clark, who led the first American expedition to the Pacific Coast and back, described and enjoyed Chinook salmon. Chinook are one of the favourite prey of killer whales.   Spawning Areas and Abundance of Chinook Salmon (Oncorhynchus tshawytscha) in the Columbia River Basin: Past and Present One of 23 reports in the series: Special scientific report--fisheries available on this by: Oncorhynchus tshawytscha (Chinook Salmon) Fishes Native Transplant.
