Proposal to continue the time series of CCAMLR-sponsored research surveys to monitor abundance of subadult Antarctic toothfish in the southern Ross Sea in 2015
Abstract: A research proposal to continue the southern Ross Sea subadult toothfish survey is ... presented. The survey will focus on estimating relative abundance in the core strata (A, B, C) in SSRUs 88.1 ... J and 88.1L. It will also carry out 15 exploratory sets in a newly defined stratum K in Terra Nova ... be retained at a total of 60 sets. A nominal catch limit of 68 tonnes, to be taken from the shelf ...

Long-term changes in the size composition of fjord Notothenia rossii, Gobionotothen gibberifrons and Notothenia coriiceps at Potter Cove, after the 1978–1980 fishery in the area
years. After 1991/92 the densities, mean sizes and abundances do not depend on a single forcing event ... but on several interacting factors. The length data of G. gibberifrons, available from 1986, show a ... decrease until 1991/92, exhibiting a similar pattern to that of N. rossii. After a period of relative ... stability in mean sizes (1992-1994) a sharp increase is associated with a continuous decline in relative ...
