摘要: Juvenile Antarctic krill (Euphausia superba) were fed the diatom Phaeodactylum tricornutum at concentrations ranging from 0.0–5.0 mgCl-1. Intermoult period (IP) decreased, but an increment of body length per moult (ΔBL) juvenile increased, up to a concentration 1.0 No further effect food on IP or ΔBL was seen beyond plateaued 23.8 days and ΔBL, 1.14 mm. The maximum daily growth rate (ΔBL/IP) calculated be 0.047 mm day-1. correlated relationship is expressed as ΔBL=-0.0066IP+2.47 (r=0.58, n=141, P<0.01). Growth conditions in Southern Ocean are discussed terms available there.
