Habitat Utilization by Juvenile Pink and Chum Salmon in Upper Resurrection Bay, Alaska
Patterns of habitat utilization by pink (Oncorhynchus gorbuscha) and chum (O. keta) salmon were studied in Resurrection Bay at a proposed small-boat harbor construction site near Seward, AK. Relative distribution and abundance of salmon fry and their predators were determined by beach seining during...
