Service Description: Commercial fishing reporting blocks for California. This feature is for reference to California commercial fisheries catch and effort data after January 1, 2025. For data prior this date, please refer to Commercial Fishing Blocks (pre Jan 1, 2025) - R7 - CDFW [ds3093] and Offshore Commercial Fishing Blocks (pre Jan 1, 2025) - R7 - CDFW [ds3148].
These commercial fishing blocks are the primary index for locating commercial catch reported to the California Department of Fish and Wildlife by landing receipt or log book record. Catch data from the Marine Landings Data System (MLDS), the (discontinued) Commercial Fishing Information System (CFIS), and the Marine Log System (MLS) will reference the spatial units found in this file. This is an updated collection of blocks effective starting Jan 1, 2025, as specified in California Code of Regulations, Title 14, Section 190.

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.
