Antarctic icefishes (Channichthyidae) – a unique family of fishes – a review
Abstract: Icefish are a family of species unique among vertebrates in that they possess no ... haemoglobin. With the exception of one species, icefish live only in the cold – stable and oxygen – rich ... environment of the Southern Ocean. It is still questionable how old icefish are in evolutionary terms: they ... they are 15 – 20 Ma old and started to evolve some time after the formation of the Antarctic ...

Preliminary assessment models of Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea including data from the 2005/06 season
Abstract: We provide an update of the Bayesian sex and age structured population stock assessment ... in a similar, though slightly higher, estimate of initial and current biomass as the 2005 base case ... model. The inclusion of the 2005 release and the 2006 recapture data had the effect of only slightly ... modifying the estimates from the models, suggesting that the new data had a similar pattern to that of ...
