Description: NOAA’s National Marine Fisheries Service (NMFS) developed a collection of commercial fishing activity maps called Fishing Footprints. These data summarize the spatial extent of fishing activity by combining Vessel Trip Report (VTR) and dealer report data and modeling the probability of a vessel’s fishing location using observer data. Data provided comply with data confidentiality requirements under the Magnuson-Stevens Act through aggregation. The data was summarized to show fishing activity in terms of pounds of fish landed (“landings”) or value (“revenue”) by Fishery Management Plan (FMP), species, fishing gear type, and time periods. Data was summarized on a 500 x 500 meter grid, showing activity within each grid cell. For more information on the Fishing Footprints methodology, please see <a href="https://repository.library.noaa.gov/view/noaa/4806" target="_blank">DePiper G.S. 2014. Statistically assessing the precision of self-reported VTR fishing locations. NOAA technical memorandum NMFS-NE-229</a> and <a href="https://repository.library.noaa.gov/view/noaa/23030" target="_blank">Benjamin S, Lee MY, DePiper G. 2018. Visualizing fishing data as rasters. NEFSC Ref Doc 18-12; 24 p</a>. <br/> <br/> For the layers on the Portal, revenue and landings have been summarized for three time periods 2011-2015, 2016-2020, and 2020-2024 for both FMP and gear type. The values represent annual averages over each 5 year period. The data shown have been filtered from the original data. Areas where revenue was less than $25 were excluded from both the revenue and corresponding landings data. Additionally, some of the species and gear types with very little fishing activity were excluded from this set of data. Data are grouped into categories for time period, gear type/FMP, and revenue/landings.
<br/> <br/> It is important to note that these public datasets have suppressed certain information due to confidentiality concerns and are meant to present general patterns of commercial fishing activity. To obtain the most accurate estimates of fishing activity, please make a request directly to NOAA via this email <A HREF="mailto:NMFS.GAR.Data.Requests@noaa.gov">NMFS.GAR.Data.Requests@noaa.gov</A>. <br/> <br/> To view these and other fishing data related to offshore wind planning and leasing, please visit this web page: <a href="https://www.fisheries.noaa.gov/resource/data/socioeconomic-impacts-atlantic-offshore-wind-development" target="_blank">https://www.fisheries.noaa.gov/resource/data/socioeconomic-impacts-atlantic-offshore-wind-development</a>
