Comparative studies on the biological and acoustical properties of krill aggregations (Euphausia superba Dana) samples during the XIII Italian Expedition to the Ross Sea (December 1997–January 1998)
(December-January 1997-98), for biological validation of hydroacoustic recordings, 35 net samplings were ... carried out. For all hauls both parameters: biological (length AT, sex and maturity stage of the gonads of ... the Euphausia superba) and acoustical (differences in volume back-scattering strength of krill ... aggregations MVBS at 38, 120 and 200 kHz) were examinated.
