The Alaska Fisheries Science Center's Ocean Carrying Capacity (OCC)
Program at the Ted Stevens Marine Research Institute supports NOAA
Fisheries role in the stewardship and management of marine resources
through fisheries oceanography investigations in support of both
stock and habitat assessments. Early research provided information
needed by the International Pacific Fisheries Commission (INPFC)
and the member nations of the Pacific Salmon Treaty to manage international fisheries in the North Pacific and salmon fisheries in transboundary rivers.
OCC continues to support Pacific Salmon Treaty research and much of the ocean research is now
coordinated through the North Pacific
Anadromous Fish Commission (NPAFC), the successor of INPFC,
and addresses broader ecosystem objectives of the North Pacific
through studies of the epipelagic ecosystem. OCC provides information
through fisheries oceanography field surveys, stock identification
and genetic stock structure of salmon and forage fish species, ecosystem
monitoring and retrospective growth studies of salmon, and laboratory
experiments on the behavioral and physiological ecology of salmon.

Bering-Aleutian Salmon International Survey (BASIS) research is a cooperative research effort by member nations of NPAFC to study the epipelagic ecosystem of the Bering Sea. BASIS was developed by NPAFC scientists to improve our understanding of salmon ecology in the Bering Sea and to clarify mechanisms linking recent changes in ocean conditions with salmon resources in the Bering Sea. OCC is responsible for BASIS research in U.S. waters.
Global Ocean Ecosystems Dynamics (GLOBEC)
research by OCC provides information on the behavioral and physiological
ecology of juvenile salmon in the Gulf of Alaska. Research evaluates
the interaction between temporal-spatial distribution of juvenile
salmon, growth performance, environmental conditions, and stage-specific
survival which are critical factors in the magnitude, location,
and timing of their marine mortality.
Ecosystem Monitoring and Analysis (EMA) research by OCC
provides indicators for ecosystem dynamics, assessment, and forecasting
by monitoring age and size of salmon populations and through retrospective
growth studies on historic collections of salmon scales. Research
is focused on constructing, analyzing, and linking time series of
salmon age, size, growth, survival, and roduction with time series
of oceanographic conditions and climate.
Stock Identification and Assessment (SIDA) research by OCC
provides information used in stock-specific fisheries management
and in ocean ecology research through the genetic identification
of stocks to region or country of origin and determination of population
and stock utilization of ocean rearing areas. Research is primarily
focused on genetic stock structure of Pacific salmon, rockfish,
and forage fish species. Products include peer reviewed manuscripts,
and technical reports; in addition to, software such as stock
composition estimation programs.
