1. Relationship between distribution of Antarctic krill (Euphausia superba) and environmental index MTEM-200 in the Antarctic Ocean throughout the year

   Abstract:  Antarctic krill (Euphausia superba) is the key species of the Antarctic marine ecosystem and human fishing resources. Essentially, relationships between krill distribution and oceanographic conditions have been an age-old recurrent problem and many papers have been published on the

2. Short note: Time series of Drake Passage Oscillation Index (DPOI) during 1952-2008 and its possible influence on environmental variability

   Abstract:  An assessment of the environmental processes influencing variability in the recruitment and density of Antarctic krill (Euphausia superba DANA) is important as variability in krill stocks affects the Antarctic marine ecosystem as a whole. Naganobu et al. (1999) had assessed variability

3. Systematic Coverage’ by scientific observers on Krill Fishing Vessels

   Abstract:  A work plan to establish an observer scheme for krill fishery was agreed at the previous Scientific Committee and the Commission. The first step was to consider ‘systematic coverage’ of the observers. In this document, Japan proposes a framework for scientific observer system for krill

4. Distribution patterns and biomasses of Antarctic krill (Euphausia superba) and ice krill (E. crystallorophias) with note on distribution of Antarctic minke whales (Balaenoptera bonaerensis) in the Ross Sea in 2005

   Abstract:  Distribution patterns and biomasses of Antarctic and ice krill in the Ross Sea in austral summer in 2005 were studied using a multi-disciplinary survey data set combining cetacean, krill and oceanography data. Two research vessels, KM and KS2, conducted the hydroacoustic surveys

5. Community Structure of copepods in epipelagic layers in the Ross Sea and neighboring waters

   Abstract:  During the 9th research cruise of the R/V Kaiyo-maru, copepod samples were collected from three layers between the surface and 200 m with RMT 8m2 along the three longitudinal lines in the Ross Sea and its neighboring waters. Twenty three copepod species belonging to 13 families were

6. A risk management framework for avoiding significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems

   Abstract:  CCAMLR adopted a new conservation measure in 2007 (CM 22-06) to ensure that significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems (VMEs) are avoided. Due to the high levels of uncertainty surrounding both the evidence of VME presence and the consequences of

7. Notification of Vulnerable Marine Ecosystems in Statistical Area 58.4.1

   Abstract:  Conservation Measure 22-06 was adopted to ensure that significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems (VMEs) are avoided. In order to satisfy the requirements of CM 22-06 a method is proposed to notify CCAMLR of the presence of VMEs and their location

8. KRILL FISHERY BEHAVIOUR IN THE SOUTHWEST ATLANTIC

   Abstract:  10 years worth of recent finescale haul-by haul krill data were used to characterize behaviour of krill fishery. Analysis of travel distance in relation to catch level revealed a pattern that mean travel distances are longer after the least catch levels, and the travel distances

9. KRILL FISHERY BEHAVIOUR IN THE 1999/2000 SEASON

   Abstract:  This document provides information on krill fishery behaviour and fishing ground condition in 1999/2000 season to assist consideration of the regional krill density and distributional conditions observed in the CCAMLR 2000 synoptic survey. The vessels seemed to have been moving around

10. UPDATED KRILL RECRUITMENT DATA FOR THE ELEPHANT ISLAND REGION OF THE SOUTH SHETLAND ISLANDS, ANTARCTICA; 2002-2008

    Abstract:  The proportional krill recruitment index is updated from 2002 to present using data from the US AMLR surveys around Elephant Island, Antarctica. Proportional recruitment indices were derived from the CMIX procedure, and were also derived as a proportion of the <30 mm length class for
