Name: Commercial Fishing Blocks _ R7 _ CDFW _ ds3204

Display Field: locationDescription

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The feature is (primarily) a 10' latitude x 10' longitudinal vector grid that defines spatial units for summarizing commercial fishing off the coast of California. The grid cells start at 32° 10.0' N latitude (just below the U.S. / Mexico border) and continue northward to 42° 40.0' N latitude (just north of the California / Oregon border). This file was generated by a fishnet (XTools) function run in ArcGIS 10.6.1 and the index IDs were transferred from the previous file through a spatial join. The origin of these block definitions can be found in CDFG Fish Bulletin 44 - The Commercial Fish Catch of California for the Years 1930-1934, Inclusive and CDFG Fish Bulletin 86 - The Commercial Fish Catch of California for the Year 1950 with A Description of Methods Used in Collecting and Compiling the Statistics. Some revision of block boundaries and indices occurred in the late 1990's or early 2000 (exact date unknown). Improvements over the previous version include correction to a small shift in cell positions, adjustments to blocks around the Mexican border and addition the large offshore 4-digit blocks previously managed in a separate file. Attributes: Block_ID: Unique identifier for commercial fishing block. locationDescription: Generalized description of block location.
