    Résumé

    Two successful experiments on definition of Antarctic krill mortality have been carried out aboard Polish vessel Dalmor II according to the pattern submitted in paper SC-CAMLR-XXVIII/BG/10. Approximately 230 to 130 kg of krill are percolated and punched through per an hour of trawling if the average catch per an hour of trawling is about 8 tons and towing speed is 2.6-2.7 knots. The key parameters of trawling which influence the value of the Antarctic krill mortality rate are: the trawl configuration and the mesh size of its segments; the speed of the vessel and the towing duration.
