Description
Due to the complex objectives of fisheries management, all aspects of data collection, data analysis, and management actions need to be reexamined. A new spatially and temporally explicit database was constructed with this focus for the total walleye pollock (Theragra chalcogramma) catch in the waters off Alaska. Three sources provide information about pollock catches, however a significant portion of the pollock catch is unobserved. Estimated total catch was similar among the three systems, but the new database makes best use of the observer data and consequently is preferred for addressing fine-scale questions about pollock management.
