Direct ageing of Antarctic krill (Euphausia superba) – potential utility of eyestalk sections for age determination
seasons. Marks consistent with annuli observed in laboratory raised krill were observed. Length at age ... 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 ...
