What We Do

The Resource Assessment and Conservation Engineering (RACE) Division, a division of the Alaska Fisheries Science Center, comprises fishery and oceanography research scientists, geneticists, pathobiologists, technicians as well as other specialists and support staff in their ongoing missions to conduct fishery surveys and oceanographic research to measure the distribution and abundance of commercially important fish and crab stocks in the eastern Bering Sea, Aleutian Islands and Gulf of Alaska. Additionally tasked with ways to help reduce bycatch and bycatch mortality, the RACE Division uses trend information derived from both ongoing surveys and associated research to analyze current effects of fishing on local marine habitats.

Fisheries Behavioral Ecology Program

This program conducts research aimed at understanding the relationships between fish behavior, environmental variables, both physical and biological and how they may influence the distribution or survival of economically important fish species. Additionally, the program analyses fishing gear performance and attempts to understand the stresses imposed on the fish and surrounding stocks during fishing activity. The overarching goal is to provide critical information needed to help improve stock survival, survey techniques and population abundance and distribution predictions.

Groundfish Assessment Program

This program regularly conducts bottom trawl surveys to assess the condition of groundfish and shellfish stocks in Alaskan marine waters. Key fish species include: walleye "Alaska" pollock, Pacific cod, arrowtooth flounder, yellowfin sole, and rock sole.

These surveys are conducted to establish the distribution and abundance of Alaska groundfish resources in the Gulf of Alaska, Bering Sea Shelf, Bering Sea Slope, and Aleutian Islands. Surveys, various tools and models are used by the program to help further understand fish and crab habitat use.

The Groundfish Assessment Program also investigates biological interactions with the environment to estimate growth, mortality, and recruitment to improve the precision and accuracy of forecasting future stocks.

Midwater Assessment and Conservation Engineering

This program combines midwater trawl surveys with acoustic echo integration technology to assess the population status of Alaska walleye pollock, whose stocks support the largest single commercial fishery in the United States, and Pacific hake stocks in the North Pacific and Bering Seas. Research is also conducted on fishing gear performance and fish behavior during the capture process in order to develop methods that reduce bycatch in commercial fishing operations.

Recruitment Processes Program

This program seeks to understand the influences that determine whether or not marine organisms survive to the age of "recruitment". Recruitment for commercially fished species occurs when they grow to the size captured or retained by nets or gear currently used in commercial fishing. For each species or ecosystem that we study, we attempt to understand what factors that cause or contribute to population fluctuations.

Research Fishing Gear Program

This program helps to manage and develop scientific fishing gear that is used in support of survey research. By designing and testing gear that meats current fishing standards as well as creating experimental approaches, this program hopes to increase overall survival viability and lower bycatch numbers. Some nets may be outfitted with various electronic sensors such as dataloggers that collect depth, temperature and global position information. additionally, camera or video "sleds" may be used to observe overall trawl performance and evaluate equipment for overall success.

Shellfish Assessment Program

Assessment biologists conduct a wide range of research and surveys on various fish, crab and shellfish species to assess the distribution and abundance of various commercially important crab and groundfish resources in the eastern Bering Sea. The collected data is used to both aid the fishing industry in locating productive fishing grounds but also to help improve the viability of future stocks. Studies include: disease, habitat, discard mortality, reproduction, growth, culturing, affects of ocean acidification
