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.
