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 ...

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 ...
