The initial focus of studies was walleye pollock (Theragra chakogramma) spawning in Shelikof Strait, Gulf of Alaska.
The choice of this population for our research was based on development of a large fishery and the substantial variation in recruitment that was observed in the late s and early by: Buy Oceanography and meteorology of Shelikof Strait, Alaska, during spawning season of walleye pollock: Results of Fisheries Oceanography Experiment (FOX) (NWAFC processed report) on FREE SHIPPING on qualified orders.
Walleye pollock are schooling fish, found on or near the sea bottom as well as at mid water and near-surface depths, although most catches are found between 50 and m. Juvenile (age 0) pollock in their first months of life are found above the thermocline (depth at which temperature rapidly decreases) in the Bering Sea.
A series of age‐specific life tables for walleye pollock (Theragra chalcogramma) in the western Gulf of Alaska was compiled for the ‐91 year classes. The life tables were utilized to perform an e.

HOLLOWED, Cohort survival patterns of walleye pollock, Theragra chalcogramma, in Shelikof Strait, Alaska: a critical factor analysis, Fisheries Oceanography, /jtbx, 5, s1, (), ().Cited by: Federal fisheries for walleye pollock occur in the Gulf of Alaska and Bering Sea Aleutian Islands.
In the Gulf of Alaska, winter fishing has traditionally targeted pre-spawning aggregations in Shelikof Strait and the Shumagin Islands. Summer fishing has often occurred on the east side of Kodiak Island and along the Alaska Peninsula.

These likely changes have ramifications for the ecosystem. The primary spawning ground for walleye pollock in the Gulf of Alaska is in Shelikof Strait (Kendall et al., ), and the spring zooplankton community coincides with abundant walleye pollock larvae and larvae of other fishes (Doyle et al., ; Doyle et al., ; Marshall et al., ).
The following is a list of the most cited articles based on citations published in the last three years, according to CrossRef. A major area of research in fisheries oceanography examines relationships between recruitment dynamics of fish populations and the marine environment.

FOCI studies in Shelikof Strait have been funded sinceand primarily involve scientists from the Pacific Marine Environmental Laboratory (PMEL) and the Alaska Fisheries Science Center (AFSC) examining recruitment of walleye pollock (Theraga chakogramma) spawned between the Alaska Peninsula and Kodiak Island in Shelikof Strait, Alaska (Reed et al., ; Schumacher and Kendall.

From this multispecies survey, we also collect oceanographic and environmental data (e.g., water temperature, etc.) to help determine the state of the ecosystem in the Aleutian Islands region.
