Mavi Köpekbalığı Prionace glauca (Linnaeus, 1758)'nın (Chondrichthyes: Charcharhinidae) Fethiye Açıklarında (Akdeniz) Kılıç Paraketası ile Yakalanması

Abstract

25 Aralık 2012'de bir Prionace glauca (Linnaeus, 1758) örneği, Fethiye'den 1200 m derinlikte 9 kılıç balığı ile birlikte bir kılıç balığı paraketa av teknesi tarafından yakalanmıştır. Yakalanan örnek TL olarak ölçüldükten sonra tartılarak (kg) fotoğraflanmıştır. Birey 85 cm uzunluğunda ve 7 kg ağırlığındaydı. Önceki çalışmalara göre, mavi köpekbalıkları özellikle Kuzey Ege Denizi'nde bolca gözlenmekteyken, kılıç balığı avcılığının zayıf olarak bölgede var olması nedeniyle çok nadir olarak rastlantısal düzeyde avlandığı kabul edilebilir. Bununla birlikte, mavi köpekbalıkları küresel yüzgeç ticaretinde önemli bir yer tutmaktadır. Bu nedenle, bu köpekbalığı türünün nüfus eğilimi hızla azalmaktadır.

Capture of a Blue Shark Prionace glauca (Linnaeus, 1758) (Chondrichthyes: Charcharhinidae) by a Swordfish Longliner off Fethiye (Mediterranean Sea, Turkey)

Abstract

On 25 December 2012, a specimen of Prionace glauca (Linnaeus, 1758) was caught by a swordfish longliner along with 9 swordfish together off Fethiye at a depth of 1200 m. The specimen caught was measured as TL and weighed (kg), and photographed. The specimen was 85 cm TL and 7 kg. According to the previous studies, blue sharks especially observed abundantly in northern Aegean Sea, and can be accepted very rare incidental catch from the Turkish coasts owing to weak presuppose of swordfish fishery. However, there is an important place of blue sharks in the global fin trade area. Therefore, population trend of this shark species is swift decreasing.
