1. Approaches to data collection and analysis for detecting and quantifying functional overlap at the scale of the individual vessell

   Abstract:  Summary Over the past years, the subject of whether there is a functional overlap between the krill fishery and pelagic krill predators has been discussed throughout the SC-CAMLR Working Groups. Specifically, these discussions centre around two key issues: a) whether there are potential

2. 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

4. 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

5. 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

6. 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

7. 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.

8. Report on fish by-catch on exploratory fishing in Divisions 58.4.1 and 58.4.2

   Abstract:  In this paper, we report on fish by-catch during exploratory fishing activities undertaken in Divisions 58.4.1 and 58.4.2 during the 2012 to 2018 seasons. Fish by-catch comprised 14 species or groups of species. In 2018, by-catch represented 12% of the total catch (43 tonnes over 307

9. Improving observer’s identification skills for better data quality through a phone application

   Abstract:  The quality of observer’s data is obviously a very important point to produce the best advices on fishery management. This paper presents the use of an application on smart phone to help observers memorizing species name. Author(s):  N. Gasco, A. Martin, C. Chazeau, C. Péron, P. Pruvost

10. A preliminary assessment for mackerel icefish (Champsocephalus gunnari) in Division 58.5.2, based on results from the 2018 random stratified trawl survey

    Abstract:  The annual random stratified trawl survey was undertaken in Division 58.5.2 in the vicinity of Heard Island and McDonald Islands during April 2018. This paper provides an updated growth model and a preliminary assessment for mackerel icefish (Champsocephalus gunnari) population structure
