At its 2011 meeting, the Scientific Committee agreed that a time series of relative abundance from a well-designed survey could be a useful input into the Ross Sea stock assessment model. The first survey was completed in February (Hanchet al. 2012a). In this paper we provide the results of the second survey in the time series.
The objectives of this second survey were:
- To carry out a longline survey to monitor subadult toothfish in the southern Ross Sea (strata A–C) using standardised gear in a standardised manner; and
- To sample additional experimental stations in adjacent areas to identify areas of high subadult abundance which could be included as strata in future annual surveys.
