1. Characteristics of interannual variation in aggregation and diurnal vertical migration of Antarctic krill at South Georgia during winter

   Abstract:  We elucidated characteristics of interannual variability in density index, recruitment index and diurnal vertical distribution for Antarctic krill in krill fishing grounds (hotspots) at South Georgia during winter based on Japanese krill fishery data during the period 1990-2012. High

3. Sharks by-catch observed on bottom longlines fishery off the Kerguelen Islands in 2006–2016, with a focus on Etmopterus viator

   Abstract:  Data collected by fishery observers aboard French deep-sea bottom longline vessels, targeting Patagonian toothfish (Dissostichus eleginoides), were examined to quantify and describe shark bycatch within the Kerguelen EEZ (northern part of the plateau). From 2006 to 2016, crew reported

4. Trophic niche of the Antarctic toothfish caught in SSRU 88.3 as inferred from fatty acids and stable isotopes

   Abstract:  To highlight ontogenetic and geographical variability in resource utilization of Antarctic toothfish, we investigated neutral fatty acid (NFA) profiles and stable isotopes (SIs) in muscles of toothfish and their potential prey (bycatch and stomach contents), captured in fisheries in the

5. Depth and temperature preferences of Antarctica toothfish (Dissostichus mawsoni) from a pilot popup satellite archival tag study in the Mawson Sea

   Abstract:  Data retrieved from five popup satellite-tagged Antarctic toothfish (Dissostichus mawsoni) released in the Mawson Sea were analyzed. Toothfish were at liberty for 36-366 days, and yielding yearlong, 15-second data records from a single, recaptured individual.  These fish occupied an

6. Stock status and population assessment of the Antarctic starry skate (Amblyraja georgiana) in Subarea 48.3

   Abstract:  The Antarctic starry skate (Amblyraja georgiana), is currently listed as “Data Deficient” by IUCN (Endicott & Kyne 2009) and is one of the main by-catch species in the longline fishery for Patagonian toothfish (Dissostichus eleginoides) around South Georgia in the Southern Ocean.
