dc.description.abstract	The euphausiid crustacean Meganyctiphanes norvegica (M. Sars) have been detected and counted in the scanning section of a 2 MHz scanning sonar beam up to 3 meters from the sonar head. The tests completes a pilot investigation on equipment needed to study krill behaviour in relation to sampling gears used for biomass estimation of euphausiids.	no_NO
