On the possibility of practical utilisation of krill target strength TS in situ obtained on the basis of EK-500 measurements
Abstract: Comparative analysis of krill length distribution in the echosurvey area, obtained with ... trawl and acoustic methods is presented. Besides, the acoustic estimate of krill length composition was ... situ at the frequency of 120 kHz as measured with echosounder EK-500 (split-beam) principle). Krill was ... caught with the commercial trawl RT 741448. It was shown that differences between krill length ...
