Because ofitsscarcity, this species does not compete with the Russian form whose eggs provide the finest caviar. The sturgeon is the largestfresh-water fish inNorth America. Arecord Columbia River specimen weighed 1,285 pounds and was 12% feet long. Four long feelers hang in front ofthesuckerlike mouth. Besides small aquatic creatures, the sturgeon may swallow the eggs, deposited on the stream bottoms, of EULACHON (Thaleichthys pacificus), schooling inthe background.
