A common-format logbook is used by Washington, Oregon, and California for all commercial vessels targeting groundfish, including those participating in the limited-entry and open access fisheries. Electronic logbook data is submitted by state agencies to the Pacific Coast Fisheries Information Network (PacFIN) regional database, maintained by the Pacific States Marine Fisheries Commission (PSMFC). This data product was created by analysts from the West Coast Groundfish Observer Program (WCGOP), Fishery Resource Analysis and Monitoring Division (FRAM) at the Northwest Fisheries Science Center, NOAA Fisheries. The WCGOP's goal is to improve total catch estimates by collecting information on the discarded catch (fish returned overboard at-sea) of west coast groundfish species. Trawl logbook data is regularly used in analyses of the bottom trawl groundfish fishery observed by the WCGOP. Since all fishing operations are not necessarily recorded in logbooks and logbook submission may not be complete, neither the maps nor the data can be used to characterize the fishery completely. We urge caution when utilizing these data due to the complexity of groundfish management and fleet harvest dynamics. A trawl towline model (line drawn from the start to end location of a trawl tow) was used to allocate data to 10 x 10 kilometer grid cells for calculation. Commonly used fishing effort metrics were calculated, such as tow duration (hrs.), groundfish catch (lbs.), number of vessels and tows. Data were summarized for each individual year between 2002 and 2008. In order to preserve confidentiality of individual vessels, cells with fewer than 3 vessels represented were excluded from this data product. Purpose: This data product was developed to provide basic groundfish fishing activity and fishing distribution information for commercial vessels operating off the western coast of the continental United States.

Use_Constraints: These data should only be used to represent the relative spatial distribution of fishing effort for commercial vessels using bottom trawl gear off the western coast of the continental United States. Since all fishing operations are not necessarily recorded in logbooks and logbook submission may not be complete, neither the maps nor the data can be used to characterize the fishery completely. Furthermore, cells with fewer than 3 vessels represented were excluded to preserve the confidentiality of their catch information.
