The California Department of Fish and Game (DFG) recently completed its first-ever stock assessment of California halibut.
Completed in July 2011, the assessment examined two separate halibut stocks off the coast of California, with the boundary drawn at Point Conception.
The results from central California indicated that the halibut stock in those waters is healthy and that fishing is currently not the major factor in controlling the abundance level of the central California population. Instead, abundance in that area is driven by pulses of large numbers of young halibut which only occur in some years. These pulses are likely environmentally influenced.
The assessment of the Southern California population showed that the stock in those waters has been depressed over the last 40 years. The southern population is nevertheless above a level which can still produce a sustainable fishery, albeit at relatively low levels. A lack of good recruitment (young halibut entering the fishery) during the last decade has prevented the stock from achieving higher abundance levels in recent years.
Funded by DFG, the assessment was conducted under contract by Dr. Mark Maunder, an internationally recognized authority on fishery modeling. DFG staff collaborated on the effort by providing numerous databases relative to the recent and historical monitoring of the commercial and recreational fisheries and from fishery-independent surveys. The final report was subjected to an independent peer review before being released.
The assessment results are now available to the public at www.dfg.ca.gov/marine/sfmp/halibut-assessment.asp.
DFG will be conducting three public meetings in Southern California to explain the results of the stock assessment and how it may affect halibut management. These meetings will be held on the following dates:
