Performance of an acoustic sonde design
Abstract: The potential of multi-frequency acoustic technology for quantifying fish and plankton ... is widely recognized. At a U.S. GLOBEC workshop in 1991, one of the considered problems was measuring ... macrozooplankton and micronekton. It was concluded that in order to survey animals in the size range 0.5-5 cm, it ... would be expedient to use at least three and perhaps as many as 8-10 frequencies in the range 38-420 kHz ...

Approaches to monitoring and assessing toothfish in new and exploratory fisheries, with particular reference to Subarea 88.1
would be imprudent to rely solely on any one of these methods at the present time. We recommend that tag ... monitor toothfish – and perhaps as importantly – the wider ecosystem effects of the toothfish fisheries ... . We further recommend that simulation studies be carried out to determine the best way to use the ... effort manipulation approach in all New and Exploratory fisheries, and in particular the current active ...

No boundaries for whales interacting with fishing activities targeting Patagonian toothfish (Dissostichus eleginoides)
Patagonian toothfish (Dissostichus eleginoides) have been documented as a severe issue in the Crozet EEZ ... since the late 90’s. Estimating depredation rates allows to correct catches and therefore to model the ... photographs from the French vessels fishing in the Crozet EEZ as well as on Del Cano rise in the Southern ... . Over the 2009 – 2019 period, and depredation rates were estimated to be around 8% in the Del Cano ...
