    Fisheries Oceanography Coordinated Investigations (FOCI) is a cooperative project involving scientists from the National Oceanic and Atmospheric Adrninistrationrs (NOAA) Pacific Marine Environmental Laboratory (PMEL) and Alaska Fisheries Science Center (AFSC), and investigators from several other research facilities and universities. The goal of FoCI is to gain an understanding of the physical and biological processes that contribute to recruitment variability of walleye pollock (Theragra chaleogramma) in Shelikof Strait. A primary focus of FOCI research is the question of when relative levels of recruitment are established in the life cycle of walleye pollock. Processes irnpacting survival of pollock during the larval stage are believed to be the most important factors affecting recruitment. Through research of these processes, FOCI investigators aim to improve infornation available to fisheries managers by providing bet,ter forecasts of year-class strength.
