Structural characteristics of fishing gears, fishing methods, fishing periods and target species were determined in order to identify the current situation of fishing activities in the Demirköprü Dam Lake. Field studies were conducted on a monthly basis between June 2015 and December 2016. Fishing activities were carried out by 75 commercial members of the Köprübaşı Fishery Cooperative with 47 licensed fishing boats on the lake. Commercial fishing on the lake was performed with gillnets, fyke nets and longlines, and the target species were; European catfish, carp, gibel carp and Danube bleak. In the study, the technical plans of 17 gillnets, 6 fyke nets and 2 longlines in different technical features being used by commercial fisheries were illustrated according to FAO standards. Official production amounts between 2008 and 2016 were used for evaluating the changes in the amount of the catch in the Lake. The highest amount of catching was observed for the gibel carp followed by carp, pike-perch and European catfish in the annual average. No catch was recorded for pike-perch, the dominant species in 2008, in the last two years. In this study, structural characteristics of fishing gears used in Demirköprü Dam Lake were described in detailed for the first time.
