Proposed Thermal Marks for Brood Year 2006 Salmon in Alaska

In Alaska, mass-marking of salmon using otolith thermal marking is an effective research and management tool applicable to a variety of situations. For brood year 2006, approximately 53 million sockeye, 7 million chinook, 505 million chum, 9 million coho, and 730 million pink salmon will be marked at 23 different hatcheries using 78 thermal marks.
