Kuzey Kıbrıs'ın Derin Denizlerinde Kadife Karınlı Fener Köpekbalığının Etmopterus spinax (Linnaeus, 1758) Yeni Kaydı

Abstract

Fener köpekbalıkları 70 - 2000 m arasındaki derinliklerde görülebilen küçük köpekbalığı türleridir. Lüminesan özellikleri nedeniyle “Fener köpekbalığı” olarak anılmaktadırlar. Kuzey Kıbrıs derin denizlerinde 13 adet trol operasyonu yapılarak, dip trolü yöntemi ile toplam 11 adet kadife fener köpekbalığı, Etmopterus spinax (Linnaeus, 1758) yakalanmıştır. Yakalanan örnekler %4’lük formalin içerisine konularak; Mersin Üniversitesi, Su Ürünleri Fakültesi, Sistematik Müzesine (Katalog numarası: MEUFC-18-11-082) yerleştirilmiştir. Örnekleme alanı olarak 274 ve 641 m arasındaki derinlikler seçilmiştir. Örneklemeler sırasında E. spinax haricinde yakalanan diğer kıkırdaklı balıklar Galeus melastomus (1 birey), Squalus acanthias (4 birey), Scyliorhinus canicula (85 birey) şeklindedir. E. spinax yakalanmış olan tüm kıkırdaklı balıkların %10.89’luk bir bölümünü oluşturmaktadır. Yakalanan tüm balıklar için tür teşhisi morfolojik özellikler yardımı ile yapılmıştır.

New Record of the Velvet Belly Lanternshark Etmopterus spinax (Linnaeus, 1758) in the Deep Seas of Northern Cyprus

Abstract

Lantern sharks are small shark species that can be seen at depths between 70 and 2000 meters.  Due to their luminescent characteristics, they have been called “Lantern shark”. In total eleven specimens of the velvet belly lantern shark, Etmopterus spinax (Linnaeus, 1758), were caught in the deep seas of Northern Cyprus by using a bottom trawl. Sampling was carried out using 13 trawling operations. The collected samples were placed in 4% formalin and stored at  the Museum of the Systematic, Faculty of Fisheries, Mersin University, (catalogue number: MEUFC-18-11-082). As a sampling area, the depths between 274 and 641 m were selected. Other cartilaginous fish caught during sampling except E. spinax were Galeus melastomus (1 individual), Squalus acanthias (4 individuals), Scyliorhinus canicula (85 individuals). E. spinax made up 10.89% of all cartilaginous fishes which were caught. Species identification for all fishes caught is made with the help of morphological features.
