PRELIMINARY ASSESSMENT OF TOOTHFISH IN SUBAREA 48.3

1. 2009 data have been incorporated in to the catch-at-age based CASAL model for toothfish in Subarea 48.3. 2. Fits to the survey data are good for the early 2000s, particularly 2004 to 2006. Fits to the catch at age data are good, except for 2009 where large numbers of age 7 and age 9 fish are not well estimated. Fits to tag recapture data are also good. 3. Projections made using median lognormal recruitment suggest a long-term yield of 3900 t. Using a recent subset of estimated cohorts suggests a lower yield.
