Age, growth and size at sexual maturity of Macrourus carinatus from the CCAMLR fisheries in division 58.5.2
Abstract: Estimates of age and growth were determined from 156 Macrourus carinatus otolith samples collected during two research voyages to Heard and McDonald Islands (Division 58.5.2) in 1992 and 1993. The estimated range of ages was 4 – 25 years. von Bertalanffy growth parameters were calculated

Revised selectivities for Dissostichus eleginoides taken by longliners in Subarea 48.3
Abstract: Kirkwood and Agnew (2001, paper WG-FSA-01/48) proposed an ad hoc method for estimating selectivity curves for toothfish taken by longliners around South Georgia and Shag Rocks over the period 1995 – 1999. This method was applied by WG-FSA-01, with minor amendments, to estimate annual age
