All gillnet data represented here expand upon vessel operations (OP table) data, all of which are collected by the United States Geological Survey, Great Lakes Science Center and its partners. The Gillnet Tables contain data collected from the research vessel deploying various gear used for gillnet data collection. The database uses sample_type to indicate the gear deployed. The tables relating to Gillnet are: GN_Annulus.csv, GN_Catch.csv, GN_Effort.csv, GN_Fish.csv, GN_L, GN_LF.csv, GN_OP.csv, GN_Prey.csv, GN_Stomach.csv, LMMB_Fish_Prey.csv, and LMMB_Invert_Prey.csv Data Quality: Note that the following data release is a snapshot of the database at the time of release. Some data quality checks are still being...

Amount of fish and shellfish caught using bottom trawling and dredging (1955-2004), by marine ecoregion. The map shows trawling and dredging fishing pressure by marine ecoregion between 1955 and 2004, using fish and shellfish catch data from the University of British Columbia (SAUP 2007). Our analysis of the catch data was limited to species caught by bottom trawl or dredge gear (Watson et al. 2006a). We calculated the annual total tonnage of catch for all species caught by these gears in each ecoregion. To account for recovery of benthic systems over time, we applied a decay factor of 2 percent for each year before 2004 to the total catch (implying a full recovery in fifty years). We then calculated the cumulative...
