An exact time of release and recapture stock assessment model applied to Macquarie Island Patagonian toothfish (Dissostichus eleginoides)
Abstract: This paper presents an assessment of the harvested population of Patagonian toothfish ... fishing season. Population models that include dynamics of tagged and un-tagged fish, daily releases ... , catches, recaptures, natural mortality, and annual net recruitment are used to assess the population of ... one of the main fishing regions of Macquarie Island: Aurora Trough.

The relative by-catches of taxa associated with vulnerable marine ecosystems by autolines and Spanish longlines
bycatches of VME taxa made by vessels using Autolines and Spanish longlines. The fractions of sets with ... positive bycatch, as well as the weights of bycatch when bycatches were observed, were higher for Autolines ... the large number of zero-bycatch sets, we found that both the amounts of positive bycatches and the ... probabilities of observing positive bycatches decreased with depth for both gears. We also found that the rate ...
