Abstract

Studies on performance capacity and selectivity of trawls used for industrial fisheries of krill (Euphausia superba) were carried out on the research vessel r/v „Profesor Siedlecki". It has been ascertained that performance capacity of the proposed trawl is about 0.86 and that chiefly small, 22—26 mm-long, krill specimens are passing through the trawl segments made of 12 mm-meshed fabric. This has an essential effect on the age-size structure of caught specimes of krill. It has been stated that the insets of less than 10 mm-mesh fabric in the bags and less than 12 mm-mesh fabric in the bellies of the trawl are practically inexpedient.
