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 ... Antarctic Division and examined using the methods outlined in (Kilada et al. 2012). Two analyses are ...
