Natural mortality rates of the Antarctic krill Euphausia superba Dana in the Indian sector of the Southern Ocean
Abstract: Data on the size and age composition of Euphausia superba were collected in the ... Cooperation and Cosmonaut Seas from 1985 to 1990. The coefficients of instantaneous natural mortality of ... E.superba in the Indian sector of the Southern Ocean were calculated according to Alverson-Carney’s (1975 ... 0.59 and from 0.94 to 2.30, respectively. The estimation of the annual extinction rate of E. superba ...

An overview of the elasmobranch fish of the Southern Ocean
Abstract: This review summarises current knowledge of the elasmobranch fish occurring in the ... Antarctic and sub-Antarctic waters of the CCAMLR area. About 14–15 species of elasmobranch have been ... recorded, with skates (Rajiformes) the most speciose order. Two genera of skates are known (Amblyraja and ... Bathyraja), although the current taxonomic knowledge of some species or species-groups is incomplete. Five ...

THE ANALYSIS OF FEEDING ACTIVITY AND DIET COMPOSITION OF ANTARCTIC TOOTHFISH D. MAWSONI IN THE ROSS AND AMUNDSEN SEAS IN THE FISHING SEASON, 2006-2007
Abstract: The results of analysis of stomachs of Antarctic toothfish D. mawsoni caught by the ... December, 2006 to 3 March, 2007 are presented. The comparative analysis of diet composition of Antarctic ... toothfish in different small-scale research units (SSRU) of subareas 88.1 and 88.2 is given. The graphs of ... size composition of food objects of Antarctic toothfish and the same by-caught objects are shown ...

Preliminary standardised CPUE analysis of the New Zealand part of the toothfish fishery in CCAMLR Subarea 88.1, from 1988/89 to 2002/03
to 2003, in Subareas 88.1 and 88.2 in the region of the Ross Sea. A preliminary standardised analysis ... of toothfish CPUE (catch (kg) per baited hook per set) carried out last year compared three ... alternative toothfish CPUE analyses for the 1998 to 2002 seasons. The analysis of a data subset including only ... relatively poor fit to the data. The variables depth, soaktime, length of line, area, and season, entered the ...

Investigation of potential biases in the assessment of Antarctic toothfish in the Ross Sea fishery using outputs from a spatially explicit operating model
-recapture data, and rely on the assumption that tagged and untagged fish have constant probabilities of ... recapture regardless of the spatial distribution of releases or subsequent fishing effort for recaptures ... that fishing effort for recaptures is distributed in proportion to the underlying abundance. Neither of ... these conditions are likely to occur in practice, and violation of this assumption may lead to bias. In ...

Further analysis of spatial patterns of benthic invertebrate habitats from fishery bycatch in the Ross Sea region
presence of VME taxa bycatch are identifiable, as are several areas of dense fishing effort with no ... evidence of VME taxa. Identifiable sponge and/or gorgonian habitats occurred at a typical scale of 10-30 km ... , but were at larger scales. Spatial analysis of these data allows the detectability of prevalent taxa ... to be estimated, along with changes in catch rate at different levels of observed bycatch. Results ...
