Understanding how environmental conditions influence productivity of Pacific salmon ( Oncorhynchus spp.) requires identifying relationships between ocean-driven processes and early marine growth and survival. We studied size, condition, and abundance

We examined physical and biological indices from Pacific salmon Oncorhynchus spp. surveys and commercial fisheries to index nearshore rearing habitats used by age-0 and age-1 Sablefish Anoplopoma fimbria in the eastern Gulf of Alaska and as indicator

To identify processes potentially contributing to the differential marine survival rates of Chinook salmon Oncorhynchus tshawytscha and coho salmon O. kisutch originating from Southeast Alaska, we compared the early marine ecology of the two species

Coho salmon (Oncorhynchus kisutch) are a vital component in the southeast Alaska marine ecosystem and are an important regional fishery resource; consequently, understanding mechanisms affecting their year-class strength is necessary from both scient

At-sea observations of predation by age-1 and older (age-1+) sablefish Anoplopoma fimbria on juvenile Pacific salmon Oncorhynchus spp. were combined with laboratory studies to determine gastric evacuation rates and were used to estimate summer predat

Bioenergetics modeling was used to estimate zooplankton prey consumption of hatchery and unmarked stocks of juvenile chum salmon (Oncorhynchus keta) migrating seaward in littoral (nearshore) and neritic (epipelagic offshore) marine habitats of southe

Interannual copepod abundance (number m−3) and sea surface temperatures (SST, 2-m depth) were examined from four stations in Icy Strait, southeastern Alaska, monthly from May to September, 1997–2002. SST was generally lowest in May (≅7°C), inc

First ocean-year juvenile Pacific salmon (Oncorhynchus spp.) in the marine waters of southeastern Alaska were examined for origin identification in the summers of 1993–1997. Over 31,000 juvenile pink (O. gorbuscha), chum (O. keta), sockeye (O. nerk
