attribute NC_GLOBAL summary String The Groundfish Analysis Team at the SWFSC Fisheries Ecology Division (Santa
Cruz) completed work on a California commercial landings database, which
includes landings from 1931 through 2007. Landings from 1931 through 1968
were recovered using funds and services provided by the NESDIS Climate
Database Modernization Program (CDMP). The recovered data, when combined with
more recent landings estimates from the California Cooperative Groundfish
Survey from 1969 to 2007, forms one of the longest detailed catch records in
the US. The 1931-68 period includes monthly summaries of catches by 10-minute
geographic blocks. These data are now openly available to the public for use
in stock assessments and monitoring of climate effects. Pearson is currently
working with the California Department of Fish and Game to extend the
geographic summary information to more recent years. Also, the taxa reported
in the historical data are the "market categories" used by fish processors,
and may involve multiple species groupings. A project has been initiated to
resolve historical landings to provide best estimates for individual species.

When using this data it is critical to understand that a market category is
NOT a species code - it is a sort group. While landings in some market
categories may consist entirely of the species for which they are named,
landings in other market categories may contain few of the species for which
they are named.

General Notes:
The data from 1930-1932 has a lot of unknown block data. When the trawl
landing data is entered, some of this may be resolved. At the same time,
some gear data will be available.

When Source Corp finishes data entry of the landing receipt data, gear code
data will be available from 1951-1968; however, this will not be completed
until around 2011.

variable market_category   short  
attribute market_category actual_range short 0, 999
attribute market_category description String When using this data it is critical to understand that a market category is
NOT a species code - it is a sort group. While landings in some market
categories may consist entirely of the species for which they are named,
landings in other market categories may contain few of the species for which
they are named. This is particularly true for the rockfish market
categories. For example, we know that only about 50% of the fish landed in
market category 253 (bocaccio) prior to 1991 were actually bocaccio. We are
currently in the process of estimating species specific landings from 1930
through 1968 (we already have the estimates from 1969-2007).

Many market categories were used in the past which are no longer included in
current market category definitions used by Fish and Game. In addition, some
market categories have been redefined including 264, 265, and 266. This
column uses the currently accepted codes and old codes were converted to new
codes. In addition, codes which are no longer used by Fish and Game, but
which were used in the past, are now included in the MASTER_MARKET_CATEGORIES
table.

variable area   String  
attribute area description String This column indicates the general area where the fish were caught if known. The values used are: Northern California, Central California, San Francisco Bay, Southern California, Mexico, Oregon, Washington, Unknown, and many international codes.
attribute area ioos_category String Location
attribute area long_name String Area
variable region   short  
attribute region actual_range short 0, 8
attribute region description String This is the California marine region in which the fish were landed. No values were present from 1951-1968. Marine regions were originally identified using 2 different numbering schemes: 10, 20, 30, 40, 50, 60, 70, 80; or 1, 2, 3, 4, 5, 6, 7, 8. For this table, the first series was converted to the second series. Definitions: 1=Crescent City area, 2=Eureka area, 3=San Francisco Bay, 4=San Francisco Ocean, 5=Monterey, 6=Santa Barbara/Morro Bay, 7=Los Angeles, 8=San Diego.
attribute region ioos_category String Location
attribute region long_name String Region
attribute region missing_value short -9999
variable block   short  
attribute block actual_range short 0, 3920
attribute block description String This column contains Fish and Game block number. Some block numbers are not present on charts, in particular, blocks >1299 are not shown on charts. All block numbers > 1299 (and some less than 1300) are used for fish imported into California. The AREA column indicates where the fish were imported from. In order to get only fish caught in California waters, you must restrict block number to less than 900. Block 0 indicates unknown area. Some information on area can be obtained from the REGION column; however, REGION is where the fish were landed and may not be where they were actually caught. This could be a problem for the northern and southern regions where fish could have been caught outside state waters. Caution should be used when using data with block=0.
attribute block ioos_category String Location
attribute block long_name String Block
attribute block missing_value short -9999
variable imported   String  
attribute imported description String 'N': the fish were likely to have been caught by US vessels and landed in California. 'Y': the fish were caught and landed outside California and imported to California.
attribute imported ioos_category String Other
attribute imported long_name String Imported
variable region_caught   short  
attribute region_caught actual_range short 1, 13
attribute region_caught description String This column was created by Pearson. It is the best guess of what CDFG region the fish were caught in. It was created by using block number (if known). If the block is unknown, then the REGION value is used (note that REGION is actually where the fish were landed).
