Interannual variations inEuphausiid life stage distribution in the Dumont d?Urville Sea from 2004 to 2008
International audience Euphausiid larvae were caught by oblique tows of a double-framed bongo net at 118 stations along the coast of Terre Adélie during every summer from 2004-2008. Larvae of Euphausia crystallorophias Holt and Tattersall and Thysanoessa macrura G.O. Sars were observed in the study...
