1. Method of age determination for Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  This work is based on material from Antarctic toothfish, collected in the Ross Sea from December 2004 to March 2005 on the longliner “Volna”.  Age was determined for 364 individuals. Currently widely applicable "the break and burn method" was used in the present work (Chilton,

2. Warming effects in the Western Antarctic Peninsula Ecosystem: the role of population dynamic models for explaining and predicting penguin trends

   Abstract:  The Western Antarctica Peninsula and Scotia Sea ecosystems appear to be driven by complex links between climatic variables, primary productivity, krill and avian predators. There are several studies reporting statistical relationships between climate, krill and penguins population size.

3. Influence of the quality and quantity of data from a multi-year tagging program on bias and precision of biomass estimates from an integrated stock assessment – update

   Abstract:  By way of simulation, this study investigated how the bias and precision of biomass estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging program, in particular the effects of the size (tag size-overlap) and numbers of tagged fish,

4. A distribution-free model of length-frequency distribution to inform fishery stratification for integrated assessments

   Abstract:  Length frequency distributions (LFD) of catch collected as a random sub-sample from hauls are an important input to integrated fish stock assessments. Statistical tests for variables that significantly influence the LFD helps in evaluating how to account for important differences in

5. On accidental catch of Champsocephalus gunnari while fishing of the Antarctic krill off the South Orkney Islands (Subarea 48.2) in 2013

   Abstract:  During the Antarctic krill fishing in the area off the North-Western slope of the South Orkney Islands shelf were caught 5000 kg of Champsocephalus gunnari.   Author(s):  L. Pshenichnov Title:  On accidental catch of Champsocephalus gunnari while fishing of the Antarctic krill off the

6. Joint CEP/SC-CAMLR workshop (2016) on climate change and monitoring

   Abstract:  The Committee on Environmental Protection and SC-CAMLR have endorsed the proposal to hold a second Joint CEP/SC-CAMLR Workshop in 2016. The agreed general scope of the workshop is to identify the effects of climate change that are considered most likely to impact the conservation of the

7. Comparing two and three frequency dB window identification techniques for estimating Antarctic krill density

   Abstract:  Three surveys of acoustic data from around South Georgia, collected using a four frequency echosounder (38, 70, 120 and 200 kHz), were used to characterise Antarctic krill. Identification of krill targets was carried out using different permutations of two and three-frequency windows.

8. A plan for Antarctic krill survey with a scientific broadband echosounder onboard R/V Kaiyo-maru in the CCAMLR Division 58.4.1 during 2018/19 season

   Abstract:  To investigate the utility of broadband sound for Antarctic krill acoustic surveys, we will conduct echo sampling with a scientific broadband echosounder EK80 (Simrad-Kongsberg) during a dedicated krill survey for CCAMLR Division 58.4.1 during 2018/19 season by Japanese research vessel,

9. Predicting fishing ground accessibility in the Antarctic Weddell Sea

   Abstract:  Sea ice is a major constraint of fishery performance in the Southern Ocean seasonal sea ice zone. We use sea ice concentration data from 2002-2017 that cover the wider Weddell Sea to establish statistical models of (i) accessibility, i.e. the probability that a particular area is

10. Estimating nest-level phenology and reproductive success of colonial seabirds using time-lapse cameras

    Abstract:  We wish to draw the attention of Members to an online application of the R code published in the attached paper. The web-based app ‘photoR’ (https://jefferson.shinyapps.io/photor2) implements  the methods of the paper and provides summary outputs for direct input to CEMP A6b and A9
