Resumen:
Antarctic toothfish (Dissostichus mawsoni) have been found in regions sampled throughout Subarea 88.3 at depths from 550–2000 m, with size distributions and catch rate (i.e. abundance), differing by area, and especially by depth. Size distributions along the slope were typically bimodal, comprised of both very small and adult fish. Toothfish catch rates were highest on the central Read More

Progress toward ecosystem-based management of the Antarctic krill fishery Submitted by ASOC
Resumen:
The Antarctic Peninsula and Scotia Sea regional ecosystem and potentially management of the krill fishery are both experiencing rapid change. This includes warming, growth in krill catches, and increasingly concentrated fishing effort, all of which impact penguins and other predators. Further, the krill fishery is expanding into areas of East Antarctica unfished since the 1990s. Here ASOC Read More

Preliminary tag-recapture based population assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.4 – 2019/20 fishing season T. Earl and A. Riley
Resumen:
The biomass of Antarctic toothfish (Dissostichus mawsoni) in CCAMLR Subarea 48.4 is estimated from tagging returns, giving an average of 1,456 tonnes since 2016. Applying the CCAMLR agreed precautionary assumption of average biomass, using the 5-year average biomass, and harvest rate of γ = 0.038, implies a 2020/21 yield of 55 tonnes.
Historically, a precautionary approach has Read More

Feasibility of establishing limits on use of continuous fishing system for the krill fishery in the Area 48 Delegation of Ukraine
Resumen:
Last 15 years (since 2005) a total catch of Antarctic krill in the Subarea 48 was sustainably increasing, remaining, however, under the trigger level of 620 000 tons. Analysis of the catch data shows that an intensity of krill fishing was slightly growing with use of traditional (conventional) trawls (krill catch by conventional trawls in 2019 is up to 46% higher than such catch in 2008), and Read More
