Description

In the North Pacific over a billion salmon are otolith thermally marked annually. In Washington State greater than 30 million Chinook, Chum and Sockeye are marked in the Columbia River, Coastal Washington and the Salish Sea each year. The goal of this marking program is to provide a cost effective mass marking tool that can provide fisheries manager’s accurate information regarding brood year of returning adults and the contribution of hatchery and wild fish to fisheries and escapement estimates. Though infrastructure costs to existing hatcheries can seem high, once in place provide a low cost marking program that can effectively mark 100% of the hatchery production. The benefits and limitations of an otolith marking program in relation to other marking techniques will be discussed.
