1. Size selectivity of the RMT8 plankton net and a commercial trawl for Antarctic krill

   Abstract:  Net selection of the scientific RMT8 plankton net and a commercial sized pelagic trawl has been studied. Selection curves indicate that krill length classes smaller 20 mm are underrepresented in the RMT8. For the commercial trawl with a liner mesh size of 12mm the length classes smaller

2. Histopathology of Antarctic krill (Euphausia superba) bearing black spots

   Abstract:  In Antarctic krill, Euphausia superba, sampled by a Japanese scientific observer onboard a krill fishing vessel in the winter of 2003 and 2006 in the South Georgia region, the Antarctic Ocean, approximately 2-5% of sub-samples of 100 krill bore small black spots. The black spots were

3. CCAMLR 2000 revisited

   Abstract:  The total abundance of krill in the Scotia Sea was estimated from an international echosounder and net survey (CCAMLR 2000) to be 44.3 million metric tons (Mt; CV=11.4%), prompting the Antarctic Treaty's Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)

4. 2007 krill biomass update of the South Shetland and Elephant Island regions of Area 48

   Abstract:  Antarctic krill biomass trends in the South Shetland Island region of Area 48 are presented. Updated time series using the Stochastic Distorted Wave Born Approximation, and a dynamic?Sv krill delineation model are used to derive krill biomass. This paper provides updated (through summer

5. A guide to identification of fishes caught along with the Antarctic krill

   Abstract:  A field key to early life stages of Antarctic fish caught along with the Antarctic krill is produced. The key includes 8 families and 28 species mainly from the Atlantic sector of the Southern Ocean and uses distinguished characters which permit rapid field identification. In some cases,

6. Distribution and abundance of Antarctic krill (Euphausia superba) off East Antarctic (30–80°E) in January–March 2006

   Abstract:  Multifrequency echosounder data were collected during the 2006 BROKE-West summer survey of Division 58.4.2 for the purposes of estimating the unexploited biomass (B0) of Antarctic krill (Euphausia superba) and its associated coefficient of variance (CV). This paper updates the version

7. Community structure of epipelagic macrozooplankton in the Ross Sea

   Abstract:  During the 9th research cruise of the R/V Kaiyo-maru, macrozooplankton 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 neighboring waters. Biomass and abundance (number of individuals) were 0 ~ 32

8. Seabird research at Cape Shirreff, Livingston Island, Antarctica, 2006/07

   Abstract:  Our tenth season of seabird research at Cape Shirreff allowed us to assess trends in penguin population size, as well as inter-annual variation in reproductive success, diet and foraging behavior. The gentoo breeding population has decreased marginally from the previous season and is the

9. Cycles of Euphausia superba recruitment evident in the diet of Pygoscelid penguins and net trawls in the South Shetland Islands, Antarctica

   Abstract:  Size and sex of Antarctic krill taken from chinstrap and gentoo penguin diet were compared to those from scientific net surveys in the South Shetland Islands from 1998-2006 in order to evaluate penguin diet as a sampling mechanism and to look at trends in krill populations. Both penguin

10. Insights from the study of the last intact neritic marine ecosystem

    Abstract:  Frank, K.T. et al. (2007: Trends Ecol. Evol. 22, 236–242) provide interesting analysis, after compiling information from 19 subregions, on how the exploited shelf ecosystems of the North Atlantic are structured, either by predation (top down) or resource availability (bottom up),
