Project Title: Workshop on spatial structure and dynamics of walleye pollock in the Bering Sea
Principal Investigator: Terrance Quinn II
Award: $55,559
Abstract
We propose to hold a 4-day workshop in summer 2009 to synthesize relevant information and modeling of the spatial structure and dynamics of the walleye pollock population in the Bering Sea. The synthesis is needed to address issues related to ecosystem effects of one of the world’s largest fisheries on a finer temporal and spatial scale than is currently available. The workshop will review information from scientific surveys and commercial fishing vessels about the spatial distribution of pollock and identify relevant factors that influence the distribution seasonally and annually. Advances in spatial modeling of the dynamics of fish populations will be presented to determine if they are relevant to improving the current pollock stock assessment model and management practices (e.g., refined spatial allocations of TAC). Finally, these reviews will be used to determine if a directed field study such as a mark-recapture study is needed to enhance current knowledge of movement patterns and changes in abundance.
