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 ...

NET-BASED VERIFICATION OF ACOUSTIC TECHNIQUES USED TO IDENTIFY ANTARCTIC KRILL
Abstract: We validate the acoustic target classification protocols developed for the Stochastic ... that were collected during two cruises to the South Georgia region in 1996. For each krill aggregation ... sampled by net we calculated the difference between acoustic backscatter at 120 and 38 kHz (Sv120-38) and ... at 200 and 120 kHz (Sv200-120). We considered the performance of 4 different acoustic target ...

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 ...
