Abstract/Summary

Mackerel icefish, Champsocephalus gunnari, larvae were sampled by weekly plankton tows in Cumberland Bay South Georgia. The formation of daily growth increments in sagittal otoliths was validated from larvae sampled 34 days apart. A mean increase of 33.7 increments occurred during this period, one per day. A major growth check 25–26 days after the hatch check may indicate the length of the yolk sac stage.
