An age-length key was prepared for Champsocephalus gunnari from the Subarea 48.3, based on the readings of otoliths collected during the R/V Holmberg survey in February 1995. Small and medium sized fish (total length 12-34 cm) predominated in the samples at South Georgia, while larger specimens (>34 cm) were scarce. Age groups 1-5 and 2-4 were well represented at South Georgia and Shag Rocks respectively. At South Georgia, a good agreement between modes in the size distribution and mean length at age was found for age groups one and two. Mean lengths at age reported here for South Georgia are in line with previous results.
