   Abstract:  For the 2014 assessment of Patagonian toothfish (Dissostichus eleginoides) around the ... Heard Island and McDonald Islands (HIMI) in Division 58.5.2, a prior for catchability q of the random ... stratified trawl survey (RSTS) was estimated by comparing abundance estimates of the survey with abundance ... estimates calculated from the tag-recaptures data on the main trawl ground.

2. A study on calibration for commercial echosounder using bottom backscattering strength 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 ...
