California Cooperative Groundfish Survey

October 2011

The California Cooperative Groundfish Survey (CCGS) started in 1978 as a cooperative effort between the California Department of Fish and Game, Pacific States Marine Fisheries Commission, and the National Marine Fisheries Service's Tiburon Laboratory (now the SWFSC Fisheries Ecology Division in Santa Cruz). The program was created to collect species composition and biological data from the commercial groundfish fishery. In 1986, Don Pearson officially took over managing the CCGS's data which are currently stored in the CALCOM database. Don and Brenda Erwin (PSMFC) jointly manage the program which currently has nine samplers (some of whom work part time). Since 1978, more than 38,000 samples have been collected. The data is used to provide species-specific landing estimates which are provided to PacFIN, as well as to provide age and length compositions used for stock assessments. The CALCOM data system is a relational database which is publicly accessible via a website. In addition to the data, the CCGS has more than 500,000 otoliths from many species going back to the early 1960s.
