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.

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.
