Summary
The vertical distribution of five species of fish larvae and their prey species was studied in late winter and summer at Cumberland East Bay, South Georgia. Prey type varied between fish species but was dominated by the copepod Drepanopus forcipatus and copepod eggs. Prey numbers increased with fish size. In summer, fish larvae and copepods were most abundant in the upper 120 m of the 265-m-deep fjord, whereas in late winter, both groups were more evenly dispersed throughout the water column.
