  • Fishery Independent Trawl Surveys
    Staff began collecting an index of California Halibut abundance in southern California in 2018.
  • Recently there has been an increase in sublegal California Halibut catch. This link opens in new tab or windowguide (PDF) depicts the best methods for releasing short California Halibut to increase their chance of survival, as well as how to identify juveniles compared to other commonly caught flatfishes.
  • Statewide Stock Assessment
    CDFW has collected and summarized recent and historical data for use in a statewide stock assessment for California halibut. Historical and current catch and biological data were included.This is the first statewide evaluation of the California halibut resource.
  • Collaborative Studies
    The project also works collaboratively with other scientific organizations to study halibut. Recently, our project has been working with the Santa Monica Bay Restoration Foundation to test a non-lethal method of determining the sex of California halibut using ultrasound.
