1. Further development of pairwise tag detection performance index and its application to the stock assessment of toothfish in the Ross Sea fishery

   . For each vessel in the fishery, every fishing haul from the nominated ‘case’ vessel was matched to one ... vessel, with a value of one representing the average performance across all vessels. The tag data from ... vessels for which the confidence interval was greater than zero and extended at or above one were selected ... to one or more ‘control’ hauls from other vessels fishing in the same time and location (i.e ...
