Modelling egg and larval transport of Antarctic toothfish (Dissostichus mawsoni) in the East Antarctic region: preliminary result using satellite data
eddy activity) covering 2011-2018, we developed the particle tracking model to investigate egg and ... larval transport of the Antarctic Toothfish in the East Antarctic region. This paper presents the ... 2-year simulation. From the result of the BB region, while strong self retention on the BB was ... observed in the experiment A-1, the majority of particles were advected eastward in the experiment A-2. A ...

Summer distribution, abundance and structure of krill populations (Euphausia superba and Euphausia crystallorophias) sampled by plankton net in the western Ross Sea (January–February 2000)
Abstract: Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000 ... ) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography ... of krill in the western Ross Sea (Antarctica). A midwater sampler-trawl (Hamburg Plankton Net) was ... used to collect zooplankton and fish larvae at 63 stations. The net was deployed normally as a standard ...

Has climate change promoted genetic fragmentation in the ice-dependent fish Pleuragramma antarcticum?
Abstract: Pleuragramma antarcticum is the only Antarctic notothenioid characterized by a complete ... pelagic life cycle and plays a major trophic role in the coastal Antarctic marine ecosystem. A previous ... genetic study investigated the population structure of this species, but used mitochondrial DNA sequencing ... pools, and population structure. In the present study, we used 16 EST-linked microsatellites to ...

ADDING CATCH AT AGE AND SURVEY DATA TO THE 48.3 TOOTHFISH CASAL ASSESSMENT
Abstract: The catch-at-age based CASAL model for toothfish in Subarea 48.3, which was presented ... in 2007, is developed and extended here to include survey data. Additional adjustments to the model ... suggested by WG-FSA-2007 are implemented. Fits to the survey length frequencies are good for recent surveys ... but in the past some cohorts have been missed by the survey. Fits to the survey CPUE are generally not ...
