Champsocephalus gunnari Lönnberg distribution on South Georgia shelf from inventory survey data collected by AtlantNIRO

A total of 8 inventory trawling surveys of the bottom fish were made on South Georgia shelf. Ch.gunnari distribution pattern markedly varied by year which can be attributed to differing survey dates.
Most dense Ch.gunnari aggregations observed were mainly in the northern, north-western and north-eastern parts of the island shelf. Near Shag Rocks they could be seen in separate years. Year-to-year fluctuations of catch per unit effort, predominance of certain groups of specimens and mean weight of the fish were obviously governed by the intensity of fishing.
