A feasibility study for stock assessment of D. mawsoni in the Ross Sea (Subares 88.1 and 88.2) using a tag and recapture experiment
Abstract: This paper reports on a feasibility study into a tag and recapture experiment for the ... fishery during the last 3 seasons. A good number of tag recoveries have been reported, mainly within the ... Jolly-Seber or variant estimators. The utility of this approach is investigated here by applying a Jolly ... -Seber estimator to simulated tagging data generated by an operating model over a range of assumed ...

A critical re-examination of the evidence for a possible dependence of Weddell seals (Leptonychotes weddellii) on Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea, Antarctica
Weddell seals (Leptonychotes weddellii), but available evidence remains inconclusive as a result of both ... . As a new approach, we also estimate Weddell seal food requirements by considering nutritional quality ... energy requirements. The energy density of potential prey items (fish and invertebrates) covers a four ... -fold range. Nutritional analysis of Ross Sea prey suggests that toothfish may represent a unique high ...
