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. 

In this study, it was aimed to characterize the feeding and diet composition of the most common pelagic chaetognath Flaccisagitta enflata. Zooplankton samples were collected using a WP-2 zooplankton net (200 µm) at three stations in the İskenderun Bay in October 2016, December 2016 and March 2017. F. enflata was the most abundant chaetognath in all samples and its proportion varied from 42 to 94%. Younger stages (I and II) dominated the population of F. enflata. In total, 1663 specimens were examined, but only 185 contained prey in their guts. The total food-containing ratio and the number of prey items for this chaetognath species were 11% and 0.1, respectively. These values varied for different maturity stages. Most food items were unidentified due to digestion. Copepods were the main food resource (36.8%) for the species. Cannibalism was also observed.

This study is the first to describe F. enflata feeding behaviour in the coastal area of İskenderun Bay. The preliminary results show that the feeding ratios were within the ranges reported for other regions in the eastern Mediterranean Sea.
