In this study was carried out between April 2015 and January 2017 at 0-120 m depth areas where commercial fishermen were fishing in North Aegean Sea, Çanakkale coasts. In this study, it is aimed to determine the species composition of caught species in trotline fishing and to determine the target and non-target catch rates. 6 different trotline types were used. As a result of 174 catching operations 7210 individuals were catched in total. When the ratio of the target species in catching with the trotlines are evaluated, the trotlines within the fishing gears such as fish pots, trammel nets and longlines catch more of the target species.
