Not less important is the great king-salmon, or quinnat (On- 
corhyachus tschawytscha), and the still more valuable blue-back 
salmon, or red-fish (Oncorhynchus nerka).

The salmon of the Atlantic (Salmo salar), the various species 
of sturgeon (Acipenser), the sardines (Sardinella), the halibut 
(Hippoglossus), are also food-fishes of great importance.
