Effectiveness of the RMT8 system for sampling krill (Euphausia superba) swarms

Polar Biology Aims and scope Submit manuscript

Summary

The effectiveness of the Rectangular Midwater Trawl (RMT) for sampling krill swarms was studied by observing the behaviour of swarms in the vicinity of the net using echosounders. Large scale avoidance was observed by day but not at night. By day krill layers dispersed to such an extent that few krill were present less than 10 m below the net. Limited avoidance by night indicates that the krill are acting on visual clues of the net's presence.
