Description
Summary:Effective management of multi-species fisheries requires reliable estimates of the amount and composition of catch and bycatch. In this report, we present the results of analyses of observer program data performed to compare several different estimators of catch and catch composition. Our analyses were applied to 1994 data collected in two fisheries selected based on data availability, representativeness, and economic importance: the walleye pollock and yellowfin sole fisheries in the USEEZ of the Eastern Bering Sea.
