    This report on the Bering Sea/Aleutian Islands pollock midwater trawl fishery is one of a six part series of reports summarizing catch per unit effort (CPUE) and bycatch data extracted from the National Marine Fisheries Service Observer Program North Pacific (NORPAC) database. Other reports cover the other flatfish, yellowfin sole, pollock (bottom), Pacific cod, and miscellaneous species f�isheries. The overall goal of this project is to help individual skippers and vessel owners maintain their bycatch rates for prohibited species (halibut, herring, red king crab, and bairdi Tanner crab) within guidelines established by the North Pacific Fishery Management Council. Data from the period 1981- 1989 are summarized by month, year, and geographic location (one half-by-one-degree latitude/longitude blocks). Five l2-month series of charts are presented, each of which shows the Bering Sea/Aleutian Islands region divided into one-half-by-one degree latitude/longitude blocks on which bar graphs illustrating average CPUEs or bycatch rates are superimposed. These chart series provide a visual overview of the data through time and space. Other sections list the actual numerical data associated with each bar graph and provide tables summarizing the databy month and year. Tables listing the Month/Block/year records with the highest CPUEs and bycatch rates also are provided.
