Preliminary assessment models of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea including data from the 2005/06 season
Abstract: We provide an update of the Bayesian sex and age structured population stock assessment ... model for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea (Subareas 88.1 and SSRUs 88.2A–B ... ), by including tag-recapture data for 2005–06 from New Zealand vessels. The updated assessment resulted ... in a similar, though slightly higher, estimate of initial and current biomass as the 2005 base case ...

A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA
Abstract: We present a quantitative food web of the Ross Sea as a step towards investigating ... ecosystem effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The model consolidates ... quantitative information on trophic links across all the major biota of the Ross Sea and tests for data ... consistency. The model has 38 trophic groups and is balanced in terms of annual flows of organic carbon in an ...

Integrated analysis of the by-catch data in the Ross Sea toothfish fishery
Abstract: The indices of exploratory toothfish fishery in the Ross Sea for the period of 2008 ... -2015 are considered. The analysis was focused on CPUE toothfish (kg/1000 hooks), by-catch CPUE (kg/1000 ... hooks) and normalized target catch ratio. There was evidence of distinct differences in the mean (and ... distribution) in the CPUE toothfish and the by-catch CPUE. Our analysis also show that target catch ratios ...
