Abstract :This study was carried out to determine the catch efficiency of crayfish fishing in Keban Dam Lake during the crayfish fishing season between July 1 and November 1, 2023. The study was conducted by applying a face-to-face questionnaire to 45 fishermen engaged in crayfish fishing, and fishing data were obtained from cooperative records. In the crayfish fishing season from Keban Dam Lake, it was found that 45 boats engaged in crayfish fishing in 5 regions, Kemaliye, Ağın, Keban, Aydıncık and Çemişgezek. A total of 43.600 fykenets were used and 33.430 kg of crayfish were caught. Aydıncık region started crayfishing for the first time this season with 16 fishermen. The CPUE values for crayfish fishing in Keban Dam Lake were found to be 10.87 g for Ağın region. 10.14 for Keban region. 6.75 for Çemişgezek region. 7.87 for Kemaliye region and 6.58 for Aydıncık region. The yield per hectare for crayfish fishing in 28.450 hectares of Keban Dam Lake was determined to be 6.3 kg. In addition, among the reasons why fishermen in the region prefer crayfish fishing; it was determined that crayfish prices are higher than fish prices and they receive their income immediately in cash.
