Linking acoustic scattering coefficient to krill fishery data: feasibility of estimating krill abundance using fishing survey
Abstract: Antarctic krill (Euphausia superba Dana) is a key species in the Southern Ocean ... fisheries. In this paper, using the multi-frequency acoustic data and the fishery data, the relationship ... between the acoustic scattering coefficient of krill swarms and catch, catch per unit effort (CPUE), catch ... per unit fishing area (CPUA) were studied for better understanding the feasibility of assessing krill ...
