Verification of the CMIX procedure on species with known age-length keys
surveys using the method of W.K. de la Mare (1994) is a conventional procedure in the WG-EMM and WG-FSA ... practice. Verification of the method was made on the materials on the Baltic cod collected in the ICES ... Subarea 26. Age-length keys for 1995-2001 and length frequency data obtained during the surveys carried ... the estimates of age composition proportions calculated using the CMIX method from those determined ...

Population structure of the Patagonian toothfish (Dissostichus eleginoides) in Australian waters
Abstract: MtDNA and microsatellite loci were used to investigate the population structure of ... McDonald Islands (CCAMLR area 58.4.2), four collections) in the Southern Ocean. Additionally, a small ... sample of toothfish from the Shag Rocks/South Georgia fishing location (CCAMLR area 48.3) was also ... examined. Striking mtDNA heterogeneity was detected among the three fishing locations; spatial and temporal ...

Incorporation of a model of krill recruitment into the Butterworth et al. Stochastic krill dynamics model (SKDM)
Abstract: The method of simulating recruitment variability using observed ratios of 0 year krill ... to the total population is validated and tested. The method also links natural mortality to krill ... recruitment. Incorporation into the SKDM increases the variability of the krill population dynamics predicted ... by the model, although median escapement is similar to the previous formulation of the model. Author ...

Growth of mackerel icefish (Champsocephalus gunnari) and age-size composition of population in subarea of the South Georgia
were studied for different periods. The analysis of age composition of icefish in subarea 48.3 showed ... that the catches consisted mainly of individuals of 2-4 age groups, where more than 60% were ... represented by fish of two contiguous age groups. It was shown that in the 1980s during a number of years the ... class. These year classes appeared against a background of the intensive icefish fishery, and krill ...
