1. Brief information on Patagonian toothfish (Dissostichus eleginoides) fishery outside the zone of CCAMLR responsibility (Statistical Area 41)

   Abstract:  Presented some data for Dissostichus eleginoides fishery in the southwestern Atlantic Ocean beyond EEZ in statistical divisions 41.3.1 and 41.3.2. Author(s):  Delegation of Ukraine Title:  Brief information on Patagonian toothfish (Dissostichus eleginoides) fishery outside the zone of

2. Manual: estimating the age of Patagonian toothfish (Dissostichus eleginoides) using transverse cross-sections of otoliths

   Abstract:  At the 2000 Fish Stock Assessment Working Group Meeting (WG-FSA-2000), differences were noted in the growth parameters being used for assessments of toothfish. To assess whether these differences were real or else due to methods of otolith preparation and reading, scientists from CCAMLR

3. Connectivity and population structure in Pleuragramma antarcticum along the west Antarctic Peninsula

   Abstract:  We asked whether silverfish (Pleuragramma antarcticum) are distributed in independent, discrete populations along the Western Antarctic Peninsula (WAP), or whether the shelf circulation leads to connectivity, by testing between rival hypotheses of population segregation and linkage. If

4. 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

5. 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

6. 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

7. 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

8. 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

9. Towards a Minimum Realistic Model for investigating trophic relationships between Antarctic toothfish and demersal fish in the Ross Sea, Antarctica

   Abstract:  We report on progress towards developing a Minimum Realistic Model for investigating trophic relationships between Antarctic toothfish (Dissostichus mawsoni) and four groups of demersal fish in the Ross Sea, Antarctica. These demersal fish are known to form a part (in some cases a

10. plotImage – software for producing augmented image plots of spatially referenced data

    Abstract:  Software is presented for the automated production of standardised image plots of spatially referenced data. While developed to satisfy the specific requirements of WG-FSA, the routines have been developed to be as generic as possible and may be useful for displaying a wide range of data
