Comparative biological characteristics of Electrona carlsbergi (Tåning) (Myctophidae) from the notal and Antarctic areas in the Southern Ocean Atlantic sector
Abstract: Some biological peculiarities of E. carlsbergi from the Antarctic and notal areas of ... the Southern Ocean Atlantic sector have been studied on the basis of the data for 1987-1989. Mean ... length of fish from the Antarctic area increased while drifting eastward in the Antarctic circumpolar ... analysed were at age 2 to the west of 35°W and 3 yr old specimens, the portion of which made up to 40% in ...

An updated spatially explicit population dynamics operating model for Antarctic toothfish in the habitable depths of the Ross Sea region
model for Antarctic toothfish in the Ross Sea region, for a medium scale spatial resolution (189 spatial ... cells) covering the Ross Sea region. We build on the previous working medium-scale model in which the ... habitat for toothfish (120 cells – semi-restricted model). Model fits to the reproductive data were ... unsatisfactory in previous models, with a much flatter maturity ogive than that derived through histology. In the ...

Features of spatial and temporally distribution patterns of krill flux in the Scotia Sea: some comments on the development of a krill fishery management in Area 48.
Abstract: The spatial variability of krill flux in the Scotia Sea calculated by using the ... geostrophic method, is analysed. For this, CCAMLR-2000 international survey data was used. The analysis was ... carried out in the 0-500 m depth ranges 50 m layers. Water mass geostrophic circulation, spatial ... to the Scotia Sea, were a subject of study. It is clearly illustrated that the geostrophic krill ...

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 ...

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 ...

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 ...
