Commercial Fishing - Urching Fishing Grounds Post MPA Map 2012

This data set consists of data collected in the summer of 2013 from fisheries mapping interviews conducted with commercial fishermen who had urchin—dive landings in the California South Coast in 2012. During interviews fishermen were asked to map their fishing grounds for 2012 and determine the relative importance of each fishing ground by allocating 100 pennies across their fishing grounds for this fishery. The spatial data from these interviews were then combined through an aggregation process where the weighted fishing grounds each fisherman gave were further weighted by their ex-vessel revenue from the urchin—dive fishery in 2012. This created spatial data sets for each port for this fishery. For regional or all port data sets, port level data was aggregated by weighting each port by the port’s total ex-vessel revenue in 2012 for the fishery based on California Department of Fish and Wildlife commercial landings data. This data set represents the spatial extent and relative value of urchin—dive commercial fishing grounds for the South Coast Region in the year 2012.
