    Résumé

    This document describes the aims and methodology of a three year project (commenced in 2012) entitled Net Escapement of Antarctic krill in Trawls (NEAT). The study will include a morphology based mathematical modeling (FISHSELECT) of different sex and maturity groups of Antarctic krill (Euphausia superba) to predict basic selective characteristics of different trawl gear and net designs. Results will be used to quantify the theoretic catch efficiency and escape mortality in different net designs and also to construct design guides, to minimize escape mortality, with descriptions of basis selective properties for krill in different trawls.
