Recommendations from an International Symposium on Pollock [ Aron and Balsiger, 1989] provide the research objectives for FOCI: determine stock structure in the Bering Sea and its relationship to physical features, and understand recruitment processes in the eastern Bering Sea. Both of these have direct implication to management of the vast resources that exist in U.S., Russian and international waters. To attain the first objective, field and modeling studies have investigated circulation throughout the deep basin. Another component seeks to establish genetic ``finger-prints'' to evaluate stock structure. In addressing the second objective, we are investigating differences between survival of eggs and larvae over the deep waters to that over the adjacent shelf. A newly established component is comparing habitats of juvenile animals around the Pribilof Islands.
