1. 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 ...

2. Decadal trends in abundance, size and condition of Antarctic toothfish in McMurdo Sound, Antarctica, 1972–2011

   Abstract:  We report the analyses of a dataset spanning 39 years of near-annual fishing for ... unit effort (CPUE) were derived from the > 5500 fish caught, the large majority of which were ... measured, tagged and released. Contrary to expectation, the length frequency of the McMurdo Sound catch was ... dominated by fish in the upper two-thirds of the overall distribution exhibited in the industrial catch for ...

5. Preliminary report of sound-speed contrast and density of krill measured on board RV Kaiyo Maru

   Abstract:  The target strength (TS) of Antarctic krill, Euphausia superba, is a scaling factor to ... convert the acoustic backscattering strength into the population density. Therefore, it is important to ... improve the accuracy and precision of the TS value. Since in situ and experimental TS measurements of ... small animals like krill are difficult, the theoretical scattering models are used to predict the ...

6. Integrated models for Antarctic krill (Euphausia superba) using survey data from 1981–2014 in Subarea 48.1

   Abstract:  The integrated modeling framework for Antarctic krill (Euphausia superba)  has been ... data collected from 1981 to 2014 near the Antarctic Peninsula. Four models of the population dynamics ... of Antarctic krill in Subarea 48.1 based on different aggregations of the data are described to ... illustrate the capabilities of the framework. Survey data collected by Germany (RMT8 net sampling from 1981 ...

10. 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 ...
