Bu çalışma, Keban Baraj Gölü'nde 1 Temmuz- 1 Kasım 2023 yılı kerevit av sezonunda gerçekleştirilen kerevit avcılığının av veriminin tespit edilmesi amacıyla yapılmıştır. Çalışma, kerevit avcılığı yapan 45 adet balıkçıya yüz yüze anket uygulanarak ve kooperatif kayıtlarından avcılık verileri alınarak gerçekleştirilmiştir. Keban Baraj Gölü'nde; Kemaliye, Ağın, Keban, Aydıncık ve Çemişgezek, olmak üzere 5 bölgede, 45 adet teknenin kerevit avcılığı yaptığı, toplam 43.600 adet kerevit pinteri kullanıldığı ve 33.430 kg kerevit avlandığı tespit edilmiştir. Aydıncık bölgesi ilk defa bu sezon 16 balıkçı ile kerevit avcılığı yapmaya başlamıştır. Keban Baraj Gölü kerevit avcılığı için CPUE değerleri; Ağın Bölgesi için 10.87, Keban Bölgesi için 10.14, Çemişgezek Bölgesi için 6.75, Kemaliye Bölgesi için 7.87, Aydıncık Bölgesi için 6.58 g/pinter/gün olarak bulunmuştur. Keban Baraj Gölü 28.450 hektar alanda yapılan kerevit avcılığı için hektara düşen verim 6.3 kg olarak tespit edilmiştir. Ayrıca bölgedeki balıkçıların kerevit avcılığını tercih etme sabepleri arasında; kerevit fiyatlarının balık fiyatlarından daha yüksek olması ve gelirlerini nakit olarak hemen almaları olarak saptanmıştır.

Investigation of Fishing Efficiency of Crayfish Pontastacus leptodactylus (Eschscholtz, 1823) in Keban Dam Lake

Öz

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.
