1. Homogeneity of body length composition of Antarctic krill within the commercial haul

   Abstract:  The homogeneity of krill length composition in commercial trawl catches (hauls) was ... difference (P>0.05) in 53 out of 60 hauls. Therefore it is concluded that sampling from one part of the ... haul provides a reasonable estimate of length composition in the entire haul as a whole. In contrast to ... investigated by comparing length compositions from different parts of the same haul. There was no significant ...
