  1. A proposal for large scale sampling of krill in the diet of predators across Area 48 to coincide with the CCAMLR synoptic survey

    Abstract:  There is a high degree of spatial and temporal variability in the population of ... Antarctic krill Euphausia superba across the Scotia Sea. Resolution of the spatial component of this ... variability requires a 'snapshot' of the krill population over the region (eg the CCAMLR B0 survey ... ) whereas temporal changes have been addressed using time-series of samples from the diet of predators. At ...

  2. ASSESSMENT MODELS FOR ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) IN THE ROSS SEA FOR THE YEARS 1997–98 TO 2008–09

    Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment ... model for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea (Subareas 88.1 and SSRUs 88.2A–B ... ), using revised catch, catch-at-age, and tag-recapture data for the 2008–2009 season. The reference model ... using the selected trips tag data and the revised maturity ogive gave a similar, but slightly lower ...

  3. CONDITIONING SMOM USING THE AGREED CALENDAR OF OBSERVED CHANGES IN PREDATOR AND KRILL ABUNDANCE: A FURTHER STEP IN THE DEVELOPMENT OF A MANAGEMENT PROCEDURE FOR KRILL FISHERIES IN AREA 48

    Abstract:  The updated version of the Spatial Multi-species Operating Model (SMOM) of krill ... -predator-fishery dynamics described in an accompanying paper is conditioned using the WG-SAM set of ... reference observations for Area 48 (the SAM calendar). Results are presented for two implementations of SMOM ... , one with the time series of krill abundance fixed on input, and the other incorporating an explicit ...

  4. Demographic studies of Antarctic krill Euphausia superba Dana in the Cooperation and Cosmonaut Seas (Indian sector of the Southern Ocean)

    Abstract:  The reproductive state and size composition of Euphausia superba collected in the ... Indian sector of the Southern Ocean from 1985 to 1990 were analyzed to estimate its growth, life span and ... mortality rates. The duration of the life cycle of E.superba exceeded 5 years in the Cosmonaut Sea and 6 ... years in the Cooperation Sea. Assuming growth for only 180 days per year, growth rates ranged from 0.120 ...

  5. Dense populations of the Antarctic scallop (Adamussium colbecki) in Terra Nova Bay (Subarea 88.1J): potential VMEs adjacent to the Terra Nova Bay ASPA (No. 161)

    Abstract:  Benthic communities of the Terra Nova Bay area (Ross Sea) close to the Italian station ... Mario Zucchelli is located, have been largely investigated in the last couple of decades. All the ... acquired knowledge supports the presence of very rich and diversified communities. This has led to the ... establishment of an ASPA (N° 161). The Antarctic scallop, Adamussium colbecki (Smith, 1902), is one of the most ...
