Comparison of NASC values calculated by swarm-based and grid-based acoustic data processing methods for Antarctic krill density estimation
Abstract: The one nautical mile integrated Nautical Area Scattering Coefficient (NASC) values of ... four surveys in 48.1 fishing area were calculated using both the swarm-based and conventional grid ... -based acoustic data processing methods. All parameter settings were consistent with the reports of SG ... -ASAM-2017 except that the dB difference window of Sv 120 kHz-Sv 38kHz is set 0 to 20 dB. And the two ...

Possible effects of different levels of fishing on krill on predators - some initial modelling attempts
Abstract: An initial attempt is made to develop the model1ing framework suggested by the Joint ... Meeting of the CCAMLR's WG-Kril1 and WG-CEMP in 1992 to address this issue. First. estimates are made ... of the parameters of predator survival rates as functions of krill abundance, by considering a krill ... developed, in which krill abundance fluctuations impact the predator population, but not vice versa ...
