These data represent estimated commercial fishing activity from <\/SPAN><\/SPAN>vessel monitoring system<\/SPAN><\/SPAN><\/A> (VMS) data, for 2011 to 2022, for the United States West Coast. The analysis units are 1-minute grids (~1.8 km or 1 nm). VMS data are provided by NMFS Office of Law Enforcement and compiled by PacFIN in \u2018Comprehensive VMS\u2019, a derived data product produced by PacFIN. Pacific States Marine Fisheries Commission (PSMFC) summarized the data using <\/SPAN>methods developed by CalPoly and BOEM<\/SPAN><\/SPAN><\/A> (Wang, et al., in Press), based on VMS Declaration Codes and estimated fishing speeds.<\/SPAN><\/SPAN><\/P>

Fishing effort is summarized using available VMS data and declaration codes reported by vessel operators. Fishing effort is determined using a speed-based approach, where successive vessel positions meeting specified speed criteria are used to construct estimated fishing tracks. Vessel trip and fishing track IDs are generated in the <\/SPAN><\/SPAN>PacFIN<\/SPAN><\/SPAN><\/A> database by using the 'Comprehensive VMS' database table and applying the maximum fishing speeds associated with each declaration code, as determined by the CalPoly/BOEM study. Each consecutive record above speed 0 and below the maximum threshold becomes a \u201cfishing track point\u201d, from which the fishing tracks are created. Fishing tracks are summarized using a 1-minute grid system, with statistics calculated for each grid unit. Unique vessels are accounted for among summaries, including those associated with \u2018grouped\u2019 declaration codes. <\/SPAN><\/SPAN><\/P>

Whiting 'group' fishery<\/SPAN><\/SPAN>: <\/SPAN><\/P>

'Group' summary of 3 individual declaration codes; Limited entry midwater trawl, Pacific whiting shorebased IFQ: declaration code 221, Limited entry midwater trawl, Pacific whiting catcher/processor sector: 222, and Limited entry midwater trawl, Pacific whiting mothership sector - catcher vessel or mothership: 223. Maximum speeds for fishing activity: 221 = 4.45 kn, 222 = 4.71 kn., 223 = 4.65 kn. Data have been filtered for confidentiality (3+ vessels). Filtering: Data are filtered for confidentiality and to remove grids intersecting ports, those outside the U.S. Exclusive Economic Zone (EEZ), and those with over 50% of the area on land. Remaining data includes 70.1% (19,462/27,746) of grids/units and represents 98.8% of the track length.<\/SPAN><\/P>
