Shifts in the demersal fish community of South Georgia
Abstract: The heavily exploited fish stocks of South Georgia have been declining since the early ... 1970's. Use of a non-parametric method revealed a significant change in this community from the ... 1986/87 survey to the 1987/88 survey. This change was the result of reductions in the abundance of ...
