Preliminary tag-recapture based population assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.4
Abstract: The biomass of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 is estimated from tagging returns to average 1109 tonnes since 2010, with a five-year (2015-2019) average biomass of 1187 tonnes. Applying the CCAMLR agreed precautionary assumption of average biomass across the time

Catch removals due to killer and sperm whale interactions across sub-Antarctic fisheries
Abstract: Fisheries are human activities that alter resource availability for species in marine ecosystems. While fisheries remove fish biomass, they may also provide new feeding opportunities to various marine predators. These species, depredating on catches directly on the fishing gear, has

Disentangling the influence of three major threats on the demography of an albatross community
Abstract: Climate change, fisheries and invasive species represent three pervasive threats to seabirds, globally. Understanding the relative influence and compounding nature of marine and terrestrial threats on the demography of seabird communities is vital for evidence-based conservation. Using
