Abstract
In this study, catch efficiency of light sticks on pelagic swordfish longline were studied. This study was carried out from September 20th of 2012 to December 31st of 2012 in Fethiye region and a total of 10 fishing operations were performed. All measurements were made on board. CPUE data of 50 swordfish that caught were compared in terms of total, lightened zone and dark zone. Mean CPUE was 131±22.72 kg/1000 hooks, CPUE of lightened zone was 352±61.32 kg/1000 hooks and CPUE of dark zone was 20±4.76 kg/1000 hooks. A total of 9 different species were caught during operations. The target species, Xiphias gladius had the highest ratio both in number (81.2%) followed by Muraena helena>Coryphaena hippurus≥Ruvettus pretiosus>Carcharhinus plumbeus≥ Lobotes surinamensis>Prionace glauca≥Alopias vulpinus ≥ Isurus oxyrinchus.
