1. Revised research plan for the exploratory longline fishery for Dissostichus spp. in Divisions 58.4.1 and 58.4.2 in 2015/16

   Abstract:  Most things related to Dissostichus spp. in the eastern side of Antarctic has not been ... known well as namely the area is data poor areas. In the Division 58.4.1 there are two stocks; one ... extends from the SSRU 58.4.1C to the SSRU 58.4.2A, and the other one to the SSRU 58.4.1H. The population ... sizes were vulnerable with a big range of about 1,000-2,000 t per SSRU in 58.4.1. During the 2004-2014 ...

3. Dynamics of Antarctic krill in the Bransfield Strait during austral summer and autumn investigated using acoustic data from a fishing vessel

   Abstract:  The Antarctic krill fisheries have evolved to operate in ever more concentrated ... biomass, distribution and swarm structure on these local scales seems critical for assessing the three-way ... interactions between krill, krill-dependent predators and the krill fishery. Acoustic data collected from the ... fishing vessels might help provide such insight. In the present work, the dynamics of krill with regards ...

4. Reconciling theoretical versus empirical target strengths of krill; effects of phase variability on the distorted wave Born approximation

   Abstract:  A model was recently proposed to predict the target strengths (TS) of Antarctic krill ... ]. Based on the distorted wave Born approximation (DWBA), the model depends upon the coherent summation of ... broadside incidence (?? 90°), but large discrepancies were observed at other angles away from the main lobe ... . As the side-lobe measurements were both higher than the model predictions and above the noise floor ...

7. Models of tag shedding for double tagging as a function of time at liberty and approximate solutions for the single tagging model in CASAL

   Abstract:  The model of tag shedding implicit in CASAL is that of Kirkwood and Walker (KW) (1984 ... ) which models the annual tag shedding (i.e. loss) rate as a constant for individual tags. The CASAL ... software applies this model correctly for fish released with a single tag but does not have the facility at ... present to correctly apply the KW model for fish released with two tags. The solution of Dunn et al. (2005 ...

8. Changes in population size of large Procellariiformes breeding in the French sub-Antarctic islands: potential influence of southern fisheries and particularly long lining

   Abstract:  Studies carried out over the past three decades in the French austral territories ... indicate that these declines are mainly the result of increased adult mortality. This high rate of ... mortality has been suspected to be the result of mortality incurred in long-line fisheries. Satellite ... outside the breeding season these populations are in contact with long-line fisheries, mainly the pelagic ...

9. INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS

   observations that contribute to the objective function via a multinomial likelihood. The multinomial likelihood ... an effective sample size (ESS) that can be used as the nominal multinomial sample size. The method ... accounts for both the variation associated with sub-sampling of the random length frequency (LF) sample for ... ageing, and random reader error when ageing fish.
