Target strength estimation of Antarctic krill, Euphausia superba by cooperative experiments with commercial trawlers
Abstract: An estimate of target strength of Antarctic krill, Euphausia superba was obtained by a series of cooperative experiments between research vessel and commercial krill trawler. Estimated target strength per 1g wet weight of Antarctic krill was-66.ldB a t the frequency of 200kHz. Average
