Trophic Analysis of Juvenile Pink and Chum Salmon ( Oncorhynchus gorbuscha and O . keta ) in Puget Sound
Pink and chum salmon (Oncorhynchus gorbuscha and O. keta) fry and Clarke–Bumpus plankton tows were collected from three beach areas in Puget Sound in spring 1970. Chum fry and benthic pump samples were taken in 1971. The diets of the young of the two species were similar. Epibenthic harpacticoid cop...
