Analysis of krill fishery operations in Subarea 48.1: spatial-time distribution of CPUE and fishing efforts
Abstract: In previous years we revealed that period 2006-2011 is characterized by the highest ... values of standardized CPUE indices in the Subarea 48.1 for the last 25 years. We continue to investigate ... krill fishery data for understanding reasons of this ‘high CPUE’ regime. The authors present the ... method. We obtained the additional evidence that ‘high CPUE’ regime’ in 2006-2011 is not associated with ...

Direct ageing of Antarctic krill (Euphausia superba) – potential utility of eyestalk sections for age determination
Abstract: We outline a method for the direct determination of age in Antarctic krill (Euphausia ... superba). Recent studies (Kilada et al. 2012), have shown that annular growth bands are present in the ... endocuticle layer of the eyestalks and gastric mill in decapod crustaceans. Here we report on a preliminary ... proof of concept study using several known age krill grown under controlled conditions at the Australian ...
