The method of acoustic express-evaluation of the krill (Euphausia superba Dana) population spatial structure and determination of its accumulations biomass, with 80 kHz echosounding frequencies has been worked out during the 7-th Ukrainian Antarctic expedition. The method error does not exceed 10 %, which permits to recommend it for usage under the Antarctic krill fishery conditions. The principal possibility to acoustically express-evaluate chorological structure of the Antarctic krill population has been shown. Formation by krill of dense accumulations of different form, elongated for 6 miles, appeared to be an expressed feature of krill behaviour during observations. The school type in krill distribution was observed as well. Parallel to this the...
