Analysis of results from demersal fish surveys at South Georgia, undertaken by the United Kingdom and the USSR, January and February 1990
Abstract / Description:
The report describes discussions and analyses of the data from a survey from MV Hill Cove in January 1990 and RV Akademik Knipovich in February 1990 around South Georgia. Both surveys were characterized by large numbers of small hauls interspersed with a few large catches. The small number of large catches cause a disproportionate increase in the estimated standing stock of Champsocephalus gunnari. The paper describes the ways in which these large hauls were considered in the analysis. No ideal method was found for incorporating the large hauls into the analysis.
