Data Disclaimer: CDFW collects data from various sources for fisheries management purposes, and data may be modified at any time to improve accuracy and as new data are acquired. CDFW may provide data upon request under a formal agreement. Data are provided as-is and in good faith, but CDFW does not endorse any particular analytical methods, interpretations, or conclusions based upon the data it provides. Unless otherwise stated, use of CDFW’s data does not constitute CDFW’s professional advice or formal recommendation of any given analysis. CDFW recommends users consult with CDFW prior to data use regarding known limitations of certain data sets.

The MFDE is not intended to be used for management purposes, and CDFW requests to be contacted if state, federal, or tribal partners need data for management reasons.

Interpretations of species with seasons spanning calendar years should be treated with caution for the final year in the data series as only a portion of the months and seasonal data will be available until the next year’s data has been reviewed by scientists. Users are strongly encouraged to consult the California Marine Species Portal(opens in new tab) and the State and Federal Fishery Management Plans found on Marine’s Data, Management and Research page.
