Large Male Chum
Called “dog” salmon because of their canine-like teeth, chum are the last salmon of the year to return to the Columbia to spawn, and their young are the first to leave for the ocean in the spring. Chum salmon generally spawn in the lower part of the Columbia River below Bonneville Dam, in areas where warm ground water pushes up through the gravel where salmon make their nests. The warm water quickly incubates their eggs.
