A fishery characterisation and stock assessment have been undertaken and accepted for SCI 6A. A single stock model was developed, based on previous studies. Models examined sensitivity to assumptions about natural mortality and year class strength variability. All models provided broadly consistent stock trajectories, and suggest SSB is currently around 67–72% SSB0. Projections out to 2020 suggested that SSB would remain well above 40% SSB0 with future catches up to the TACC.
