Preliminary Results on the Feeding and Gut Content of Flaccisagitta enflata in Coastal Areas of İskenderun Bay (Northeastern Mediterranean Sea)

Öz:
In this study, it was aimed to characterize the feeding and dietcomposition of the most common pelagic chaetognath Flaccisagittaenflata . Zooplankton samples were collected using a WP-2zooplankton net (200 μm) at three stations in the İskenderun Bay inOctober 2016, December 2016 and March 2017. F. enflata was themost abundant chaetognath in all samples and its proportion variedfrom 42 to 94%. Younger stages (I and II) dominated the populationof F. enflata. In total, 1663 specimens were examined, but only 185contained prey in their guts. The total food-containing ratio and thenumber of prey items for this chaetognath species were 11% and 0.1,respectively. These values varied for different maturity stages. Mostfood items were unidentified due to digestion. Copepods were themain food resource (36.8%) for the species. Cannibalism was alsoobserved.This study is the first to describe F. enflata feeding behaviour in thecoastal area of İskenderun Bay. The preliminary results show thatthe feeding ratios were within the ranges reported for other regionsin the eastern Mediterranean Sea.

İskenderun Körfezi (Kuzeydoğu Akdeniz) Kıyısal Sularında Flaccisagitta enflata (Grassi, 1881)’nın Beslenmesi ve Bağırsak İçeriği Üzerine İlk Gözlemler

Öz:
Mevcut çalışmada, en yaygın pelajik ketognat olan Flaccisagitta enflata ’nın beslenmesi ve besin kompozisyonu karakterize edilmeye çalışılmıştır. Zooplankton örnekleri, İskenderun Körfezi’nde Ekim ve Aralık 2016, Mart, 2017 periyotlarında 3 istasyonda WP-2 zooplankton kepçesi (200 μm) ile toplanmıştır. Ketognatlar içinde, F. enflata, tüm periyotlarda baskın tür olarak gözlenmiş olup, oranı %42–94 arasında değişim göstermiştir. Erken olgunluk aşamaları (I ve II) F. enflata populasyonunda baskın olarak gözlenmiştir. Toplam 1663 birey incelenmiş olup, bunlardan sadece 185 bireyin bağırsağında besine rastlanmıştır. Bu tür için toplam besin içerme oranı (FCR) ve ketognat başına düşen besin miktarı (NPC) sırasıyla %11 ve 0.1 olarak bulunmuştur. Bu değerler olgunluk aşamalarına göre farklılık göstermiştir. Çoğu besin sindirilmiş olduğundan dolayı tanımlanamamıştır. Tanımlanan besin canlılar arasında kopepodlar ana besin kaynağını oluşturmuştur (%36.8). Bununla birlikte kannibalizm’de gözlenmiştir. Bu çalışmada ilk kez İskenderun Körfezi’nin kıyısal alanında F. enflata ’nın beslenmesi ile ilgili bilgiler elde edilmiş ve ilk gözlemler beslenme oranlarının Doğu Akdeniz’in diğer alanlarından elde edilen sonuçlar ile benzer olduğunu göstermiştir.
