1. Effects of recruitment variability and natural mortality on Generalised Yield Model projections and the CCAMLR Decision Rules for Antarctic krill

   Abstract:  AMLR krill sampling data was supplied to the Generalised Yield Model as the "vector of recruitments" input option to simulate the population dynamics of krill in the Antarctic Peninsula region (Subarea 48.1) under various assumptions. The annual proportions of krill less than

2. The first site of the Marine Protected Area network in the Akademik Vernadsky Station region: Argentine Islands, Skua Creek

   Abstract:  In 2005-2011 the Ukraine delegation at the CCAMLR presented to the Scientific Committee a series of documents with a proposal to establish Marine Protected Area (MPA) in the Akademik Vernadsky Station area with the purpose of protecting natural and geographical objects and establish test

3. Dense populations of the Antarctic scallop (Adamussium colbecki) in Terra Nova Bay (Subarea 88.1J): potential VMEs adjacent to the Terra Nova Bay ASPA (No. 161)

   Abstract:  Benthic communities of the Terra Nova Bay area (Ross Sea) close to the Italian station Mario Zucchelli is located, have been largely investigated in the last couple of decades. All the acquired knowledge supports the presence of very rich and diversified communities. This has led to the

4. Temporal variability in Adélie penguin CEMP parameters and their response to changes in prey availability

   Abstract:  We examined the within- and between- year fluctuations of four Adélie penguin population parameters which are thought to be sensitive to changes in prey availability: breeding success, foraging trip duration, meal mass and fledgling weights. Some years had either good breeding success

5. Recalculation of Antarctic krill (Euphausia superba) biomass off East Antarctica (30–80°E) in January–March 2006

   Abstract:  We recalculated krill biomass for the 2006 BROKE-West (CCAMLR Division 58.4.2) summer survey.  The recalculation was carried out on the calibrated, multi-frequency acoustic data described in Jarvis et al. (2010) Deep-sea Res. Pt II 57:916-933.  Biomass recalculation methods conformed to

6. Net escapement of Antarctic krill in trawls

   Abstract:  This document describes the aims and methodology of a three year project (commenced in 2012) entitled Net Escapement of Antarctic krill in Trawls (NEAT). The study will include a morphology based mathematical modeling (FISHSELECT) of different sex and maturity groups of Antarctic krill

7. Impacts of ocean acidification on Antarctic krill biology: preliminary results and future research directions

   Abstract:  This study reports some preliminary results of the impacts of Ocean Acidification due to elevated seawater pCO 2 on the activity, mortality, moulting of post-larval krill.  Increased CO2 levels increased mortality, reduced activity levels and fitness, and caused moult cycle

8. Modelling growth and reproduction of Antarctic krill: implications of spatial and temporal trends in temperature and food for ecosystem-based management of krill fisheries

   Abstract:  Errors in the growth model used in stock assessments of Antarctic krill, specifically higher rates of growth than occur in reality, could inadvertantly lead to over-exploitation of the krill population and cause impacts on krill predators.  We review the three classes of models available

9. Towards developing a feedback management procedure for the Antarctic krill fishery

   Abstract:  We present a feedback strategy, founded on CEMP data, to adjust the catch limit and the spatial distribution of fishing activity for Antarctic krill in Statistical Area 48. The CEMP currently provides decades-long baseline time series and useful contrasts across areas and species that

10. Method for collecting of data on traumatic death of krill passed through the trawl meshes

    Abstract:  Fishing for krill Euphasia superba Dana has been conducting using midwater trawls of different constructions including beam-trawl for several last decades. Not all krill in harvesting zone of midwater trawl got to catch during trawling. Depending on stock structure, size and
