2. An integrated assessment model for Antarctic krill: progress update

   under development for Antarctic krill are compared to estimates from CMIX and TrawlCI using the same net ... trawl data. The different configurations of the integrated model were varied based on whether acoustic ... data or net densities were used as model inputs for the biomass data, on how the biomass data were ... weighted, by whether natural mortality was estimated by the model or pre-assigned a value of 0.8, and by ...

3. Influence of krill availability on humpback whale breeding success

   Abstract:  The abundance of the Antarctic krill (Euphausia superba) has been declining in the ... western Antarctic Peninsula (WAP), probably as a consequence of the effects of the considerable increase ... in the sea surface temperature observed in the region. Thus, the performance (reproduction and ... survival) of the krill consumers may be compromised. In the present study, we investigated the reproductive ...

5. IMPACTS OF CLIMATE CHANGE ON ANTARCTIC MARINE ECOSYSTEMS: A CALL FOR ACTION

   Abstract:  Climate change has emerged as an important topic in Antarctic research over the past ... decade, but little in the way of policy or operational change has resulted at CCAMLR. Over the past 50 ... years major alterations of the ecological workings of the Southern Ocean have been underway. These ... changes are accelerating as time passes, including regional changes in sea ice persistence and extent. The ...

8. Krill population dynamics at South Georgia: implications for ecosystem-based fisheries management

   Abstract:  The South Georgia region supports a large biomass of krill that is subject to high ... interannual variability. The apparent lack of a locally self-maintaining krill population at South Georgia ... means that understanding the mechanism underlying these observed population characteristics is essential ... to successful ecosystem-based management of krill fishery in the region. Krill acoustic-density data ...

9. Feedback management through effort regulation

   Abstract:  The interim distribution of the trigger level in the fishery for Antarctic krill (CM 51 ... -01) will be revised in 2016. The trigger level is not related to the status of the krill stock and ... the predators that depend on it. Progressing the development of an operational FBM system in ... accordance with the Convention has been set as a high priority by CCAMLR. There are currently three FBM ...
