Maritimes region longline and trap fisheries footprint mapping for marine spatial planning and risk assessment / by S. Butler, D. Ibarra and S. Coffen-Smout. : Fs97-6/3293E-PDF

"This report shows commercial fishery footprint maps for directed fisheries using bottom and pelagic longlines for groundfish and large pelagics respectively, and traps for hagfish, LFA 41 and Grey Zone lobster, snow crab, and other crab on the Scotian Shelf, the Bay of Fundy, and Georges Bank in NAFO Divisions 4VWX and Canadian portions of 5Y and 5Z. Bottom longline and trap fishery maps aggregate commercial logbook effort (bottom longline soak time and logbook entries) per 2-minute grid cell using 2002-2017 data. Pelagic longline maps aggregate speed-filtered vessel monitoring system (VMS) track lines as vessel minutes per km² using 2003-2018 data. The following maps are publicly available and included in the report for multiple applications in marine spatial planning and ecological risk assessment: 1) multi-year and quarterly composite maps and data layers aggregating fishery footprints for bottom longline and trap gear, and 2) yearly and monthly composite maps and data layers for pelagic longline. Yearly maps and data layers for bottom longline and trap gear were also produced for internal use and management-related decision making … "--Abstract, page v.
