An integrated stock assessment of Patagonian toothfish (Dissostichus eleginoides) in CCAMLR Subarea 48.4

This paper describes an update to the CASAL assessment of Patagonian toothfish (D. eleginoides) in Subarea 48.4. The assessment data time series are updated with the observations for the 2014/15 season and several minor changes to the assessment are made: revision of tagging and recapture data for the full time series, a revised maturity ogive, and changes to the assumed tag growth retardation period. Stock projections indicate that the stock is in healthy condition and that an annual yield of 47 tonnes is consistent with the application of the CCAMLR harvest control rule. Data deficiencies and areas for future work to further improve the assessment are identified.
