Distribution of fish larvae at South Georgia: horizontal, vertical, and temporal distribution and early life history relevant to monitoring year-class strength and recruitment

Abstract / Description: 

Four studies on the early life history stages of Antarctic fish at South Georgia are reported. In winter and summer fish larvae and early juveniles were present over the continental shelf and abundant near the coast, but rare in oceanic waters. During winter in the 265 m deep fiord of Cumberland East Bay the early stages of many species were found throughout the water column. In summer only four species of larvae were abundant, they were found in the upper 100 m of the water column, especially the top 2 m layer at certain times of day. In both seasons some species showed daily vertical migration.

The findings are discussed in relation to surveys for sampling the early stages of fish at South Georgia, with special reference to the early life history of Champsocephalus gunnari.
