    Resumen

    A revision of the calculation of total international catch at age of Champsocephalus gunnari over the period 1976/77 to 1990/91 is presented. This uses iterative application of two age length keys to obtain age distributions, according to a method described by Kimura and Chikuni (1987). It is proposed that the revised catch at age be used for future assessment of the C. gunnari fishery at South Georgia using VPA.
