Proposal for a CCAMLR-sponsored research survey to monitor abundance of pre-recruit Antarctic toothfish in the southern Ross Sea
Abstract: The exploratory longline fishery for Dissostichus spp. has now been operating for 14 ... years in Subarea 88.1 and for nine years in Subarea 88.2. The research and assessment work in these ... areas on the distribution, abundance and demography of Antarctic toothfish (D. mawsoni) has led to an ... estimate of the fisheries potential yield. However, one source of ongoing uncertainty in the stock ...

Towards the development of an assessment of stock abundance for Subarea 88.2 SSRUs 88.2C–G – a discussion paper
Abstract: This paper frames a discussion for improving the assessment of toothfish abundance for ... SSRUs 88.2C–G. We initially provide a characterisation of the fishery and a summary of available tagging ... 2 fish have been recaptured. It is likely that the lack of tag recaptures in this region has been ... caused primarily by the poor spatial overlap of released tagged fish with subsequent fishing effort. By ...
