    This paper describes a preliminary CASAL based assessment of Patagonian toothfish (D. eleginoides) in Subarea 48.4. The assessment data are updated with the observations for the 2013/14 season and sensitivity analyses conducted using the maturity ogive from the area 48.3 and revised growth assumptions. The revised assessment is compared with the previous assessment for this stock. Stock projections indicate that an annual yield of 40 tonnes is consistent with the application of the CCAMLR harvest control rule. Links with other toothfish stocks are discussed based on tag recaptures.
