Fisheries risks to the population viability of black petrel (Procellaria parkinsoni)
Abstract: Data on the main population of black petrel (Procellaria parkinsoni), which breeds on ... Great Barrier Island, were analysed. Three types of data were available. The most useful was abundance ... population. The mean age of first breeding for black petrel is estimated to be 6.7 y. Before this, new adults ... spend an average of 1.2 y in the colony as pre-breeders, with only 3% skipping the pre-breeder phase. Of ...

An investigation of integrated stock assessment methods for the Patagonian toothfish (Dissostichus eleginoides) in Division 58.5.2 using CASAL
primarily based on the 2005 assessment implemented in the Generalised Yield Model (GYM) using survey data of ... the abundances of juvenile fish but adding fishery catch-at-length data, including a standardised ... catch-per-unit-effort (CPUE) series. The base-case scenario was then extended to include estimates of ... between estimating natural mortality and selectivity for the different fisheries. The results of this work ...

Further development of a spatially explicit population dynamics operating model for Antarctic toothfish in the Ross Sea region
spawning (based on GSI data), CPUE, and tag-release and tag-recapture observations. 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 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 ...
