A study on calibration for commercial echosounder using the bottom backscattering strength from a fishing vessel near the South Shetland Islands in Antarctic
fishing vessel to use it in estimating biomass of Antarctic krill (Euphausia superba). The method of ... calibration was to analyze the difference between the bottom backscattering strength of the commercial ... echosounder (i.e. ES70) and the scientific echosounder (i.e. EK60) at some transects designated by CCAMLR ... . 38kHz and 120kHz were used for the calibration, and krill swarm signals, obtained from multi frequencies ...

Options for allocating the precautionary catch limit of krill among small-scale management units in the Scotia Sea
Abstract: With the intent of stimulating discussion, we present four options for subdividing the ... precautionary catch limit of krill for Area 48 into the small-scale management units (SSMU) adopted at CCAMLR ... -XXI. The first three are static allocations: the first is proportional to estimated predator demand in ... each SSMU; the second is proportional to the estimated standing stock of krill in each SSMU; and the ...
