    Résumé

    Combination of conventional and continuous techniques during krill fishery at the Russian commercial vessel "Maxim Starostin" allowed to compare the size structure of the Antarctic krill (Euphausia superba) caught by these two techniques. Results of comparison are discussed in relation to the selectivity of fishing gears and the space-time variability of krill. Differences between size composition of krill caught by conventional and continuous techniques of fishery which could be connect with the trawls selectivity weren’t found. At the same time results of the analysis didn’t indicate that there were no differences between selectivity of conventional and continuous trawls. We assume that the possible influence of differences between selectivity of fishing gears were exceeded by significant space-time variability of Antarctic krill.
