Swarm characteristics of Antarctic krill Euphausia superba relative to the proximity of land during summer in the Scotia Sea
Abstract: We studied the relationship between the proximity of land and the distribution and swarming characteristics of Antarctic krill across the Scotia Sea in January and February 2003. Krill swarms identified with a Simrad EK60 (38 kHz, 120 kHz) echosounder were grouped into 4 categories

Short communication: Diet composition of deepwater icefish Chionobathyscus dewitti Andriashev et Neelov, 1978 (Chionobathyscus, Channichthyidae) from the Ross Sea area
Abstract: For the first time the study of diet composition of deepwater icefish Chionobathyscus dewitti was conducted through Antarctic toothfish Dissostichus mawsoni acted as an “agent”, i.e., all analyzed icefish individuals were taken from stomachs of toothfish caught in the Ross Sea in 2010

Definition of age characteristics of Antarctic toothfish (Dissostichus mawsoni) from the Indian Ocean sector of the Antarctic region
Abstract: For the determination of the age of Dissostichus mawsoni used otoliths and scales. All samples were collected in the Indian Ocean sector of the Southern Ocean. Methods are described. Otoliths were measured and weighed. All major life periods in corresponding ecological conditions are

Feasibility of lead-radium dating the otoliths of blackfin icefish (Chaenocephalus aceratus) and ocellated icefish (Chionodraco rastrospinosus)
Abstract: Application of lead-radium dating was attempted as a feasibility study for otoliths of blackfin icefish (Chaenocephalus aceratus) and ocellated icefish (Chionodraco rastrospinosus). Because otoliths from these fishes were small and the number of otoliths available low, a whole otolith

Distribution and population structure of Dissostichus eleginoides and D. mawsoni on BANZARE Bank (CCAMLR Division 58.4.3b), Indian Ocean, Antarctic
Abstract: Distribution, relationship between sizes and depths, sex ratio, size composition and maturity condition for Dissostichus eleginoides and D. mawsoni were investigated on Banzare Bank, using the biological data sampled by a Japanese commercial fishing vessel during austral summer from 2006

Analysis of observer coverage for Japanese krill fishing vessels
Abstract: Sources of variability of krill mean length and fish bycatch number was investigated to explore proper allocation of scientific observers on Japanese krill fishing vessels using the data from 1995 to 2008. Based on the multistage sampling theory, we derived the equation of variance in

Development of methods for evaluating the management of benthic impacts from longline fishing using spatially explicit production models
Abstract: An important management objective for CCAMLR in the high seas region of the Antarctic is to develop appropriate methods of monitoring and managing impacts of bottom fisheries on vulnerable marine ecosystems (VMEs). We describe a spatially explicit production model that can be used to

Revised impact assessment framework to estimate the cumulative footprint and impact on VME taxa of New Zealand bottom longline fisheries in the Ross Sea region
Abstract: In 2008-2009 New Zealand developed an impact assessment framework to estimate the likely impacts of bottom longline fishing on vulnerable benthic invertebrate taxa, termed Vulnerable Marine Ecosystems (VMEs), consistent with the requirements of Conservation Measure 22-06 (Bottom fishing
