SWFSC Fisheries Ecology Division researchers Xi He and John Field presented the results of the bocaccio and widow rockfish stock assessments to the Pacific Fishery Management Council’s Scientific and Statistical Committee on September 11-14, 2009. Both assessments were formally adopted by the Council for management purposes.
Results show that widow rockfish stock status has nearly rebuilt to the target level, with the 2009 spawning output estimated to be approximately 38.5% of an unfished population. Similarly, the best estimate of the relative stock status of bocaccio has improved since the last assessment in 2007, with the current spawning output estimated to be 28% of the unfished level in 2009. Population trajectories for both stocks indicate a continued increase in abundance in the near future.
Draft rebuilding plans for both species were delivered to a review panel to take place in Seattle later this month, and will be considered by the PFMC in November, 2009.
