2. Age/length key for Champsocephalus gunnari from South Georgia; Hill Cove survey, January 1990

   Abstract:  Discrepancy was noted between the age length key and modes in the length distribution ... of Ch. gunnari from the Hill Cove survey around South Georgia in January 1990. A revised age length ... key for this survey is proposed, based on data from a previous survey in the area. The revised age ... length key corresponds well to modes in the length distribution from the survey and to another key ...

3. Analysis and modelling of the Soviet Southern Ocean krill fleet, II: Estimating the number of concentrations and analytical justification for search data

   Abstract:  In this paper, I show how data that are routinely collected by survey vessels can be ... used to estimate the number of Concentrations of krill (in the sense of Butterworth (1988), Mangel ... (1988)) in a given region of the southern ocean. Sample computations are performed, using data collected ... by Soviet research/survey vessels in the early 1980s. These examples highlight the need for a ...

4. Potential for using CCAMLR VMS data for compliance analysis and data quality assurance

   Abstract:  In response to a request from the Scientific Committee the Secretariat has initiated a ... process to utilise VMS data for data-quality assurance in relation to catch data. This represents a change ... in focus on the use of VMS data by CCAMLR and requires a contingent change in emphasis on data ... quality assurance processes in order to ensure that the VMS can be used with an appropriate degree of ...

5. Further calculations of the effects of krill fishing on predators

   situation where predator survival rates depend on other factors in addition to krill biomass. This is ... random component in the relationship between krill biomass and availability. An examination of the ... consequences in the case of the blackbrowed albatross suggest that these other factors result in yet lesser ... estimate the levels of krill harvesting which would result in halving the sizes of various krill predator ...

6. PHYSICAL CONTROLS ON CORAL COMMUNITIES ON THE GEORGE V LAND SLOPE: SOME WORKING HYPOTHESES

   been identified as a Vulnerable Marine Ecosystem in the Antarctic. The challenge is now to understand ... slope in depths of 570 – 950 m. Based on these results we propose some working hypotheses to explain ... their distribution. Icebergs scour to 500 m in this region and the lack of such disturbance is probably ... a factor allowing growth of rich benthic ecosystems. In addition, the richest communities are found ...

7. ADDING CATCH AT AGE AND SURVEY DATA TO THE 48.3 TOOTHFISH CASAL ASSESSMENT

   Abstract:  The catch-at-age based CASAL model for toothfish in Subarea 48.3, which was presented ... in 2007, is developed and extended here to include survey data. Additional adjustments to the model ... but in the past some cohorts have been missed by the survey. Fits to the survey CPUE are generally not ... retardation period and rate of tag loss. When these factors are included in the model the fits to the tag ...

8. Informative approaches to ageing Antarctic fishes

   considered in terms of the passage of time (chronological age), and it can also be examined as ' ... ;physiological time'. In this regard otoliths and post-mitotic tissues may contain a large amount of ... biological and ecological information about a fish's age and past life history. In otoliths this ... correlated and that species differences in shape exist. Regression analyses of otolith dimensions may make it ...
