Approaches to monitoring and assessing toothfish in new and exploratory fisheries, with particular reference to Subarea 88.1
would be imprudent to rely solely on any one of these methods at the present time. We recommend that tag ... , quantitative research longline surveys, experimental manipulation of fishing effort, tagging programmes, bottom ... trawl surveys of juvenile grounds, and acoustic surveys. Because of potential biases we believe that it ... recapture experiments, or trawl surveys, be used in conjunction with experimental manipulation of effort to ...

CIRCULATION IN THE ROSS SEA SECTOR OF THE SOUTHERN OCEAN: REPRESENTATION IN NUMERICAL MODELS
Abstract: The circulation in the Ross Sea sector of the Southern Ocean is examined in three ... numberical models of intermediate to high resolution. Despite the model differences (including physics ... , forcing) the circulation representation is relatively consistent, both in terms of the mean and some ... aspects of monthly variability. This could point to strong bathymetric constraints on the circulation. In ...
