Estimating fishing gear selectivity for trawlers using length-frequency data from concurrent commercial trawl and longline fishing for Patagonian toothfish in Division 58.5.2 and the ratio of their hazard functions
assuming that, for the upper range of lengths, fish are fully selected by longliners but not by trawlers ... by a technique used to model grouped survival data. The hazard function relates to the event of a ... function to give the GLMM formulation. Random effects of haul identifier and ‘season by length bin’ were ...

Population identity, site-fidelity, movement ranges and preliminary estimates of abundance of southern right whales in the Antarctic Indian sector inferred from genetic markers
nucleotides of the mtDNA control region, genotyped at fourteen microsatellite loci, and the sex determined by ... individual matching (‘mark-recapture’) were detected (four males and four females). Individual matching by ... multi-locus genotypes was supported by mtDNA, sex determination, and in two cases where pictures were ... available, by photo-identification. These eight re-captures suggested that individual whales tended to ...

Predation release of Antarctic silverfish in the Ross Sea: how sensitive is the conclusion to uncertainties in the diet of Antarctic toothfish over the shelf?
toothfish stomachs showed that toothfish consume only a small proportion of silverfish (1.9–5.6%W i.e. by ... predation by fishing (643 tWW/y) was equivalent to 2.4% of the amount of silverfish estimated to be consumed ... annually by Adélie penguins in this region. This result was inconsistent with predation release of ... alternative indirect pathways through the food-web by which changes to toothfish could affect Adélie penguins ...
