Download FAR 2013/41 A review of hoki and middle-depth summer trawl surveys of the Sub-Antarctic, November December 1991–1993 and 2000–2009

There have been thirteen summer trawl surveys for hoki and other middle depth species in Sub-Antarctic waters between 1991 and 2009. These surveys follow a standard approach using the research vessel Tangaroa. This report provides fisheries-independent data for a much broader range of species than is available in annual survey reports. Biomass and distribution data are presented for 134 species or species groups, while catch rate and length frequency data are presented by survey for 35 species.
