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 ... in a similar, though slightly higher, estimate of initial and current biomass as the 2005 base case ... model. The inclusion of the 2005 release and the 2006 recapture data had the effect of only slightly ... modifying the estimates from the models, suggesting that the new data had a similar pattern to that of ...

Estimates of parameters ... appeared to broadly reflect the hypothesised spatial distribution of Antarctic toothfish, suggesting that ... younger fish were found predominantly in southern areas of the Ross Sea shelf, mature fish on the slope ... and spawning fish in the northern areas of the Ross Sea region. Fits to the observations were ...

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 ...
