Assessment of the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity to include data from 1997 to 2016
The assessment of the Prince Edward Islands (PEI) toothfish (Dissostichus eleginoides) resource carried out by Brandão and Butterworth (2016) is updated to take further data now available for 2016 into account. This update again also incorporates (now updated) tag-recapture data and a new basis to e...
