Lagocephalus sceleratus (Gmelin, 1789) (Osteichthyes: Tetraodontidae)’un Yağ Asidi Bileşimi

Akdeniz’in en istilacı türlerinden biri olan Lagocephalus sceleratus Kızıl Deniz’den göç etmiş ve bölgede hızla yayılmaya devam etmektedir. Bu çalışmanın amacı, bu türün beslenme açısından olası kullanılabilirliğini belirlemektir. Uzun zincirli aşırı doymamış yağ asitleri; docosahexaenoic asit (DHA) ve eicosapentaenoic asit (EPA) insan sağlığı için faydalıdır. Bu yağ asitlerinin en iyi doğal kaynağı başlıca balık olmak üzere deniz ürünleridir. Bu çalışmada L. sceleratus’un toplam lipid miktarı ve yağ asidi bileşimi tespit edilmiştir. Dorsal kasta toplam lipid miktarı %1,82 olarak belirlenmiştir. EPA (%6,08) ve DHA (%15,68) yüzdeleri yüksek bulunmuştur. Elde edilen sonuçlar, L. sceleratus’un iyi bir besin değerine sahip olduğu anlamına gelebileceğini göstermiştir. L. sceleratus’un zehir etkisinin giderilmesinden sonra, bu türün besin maddesi olarak tüketilmesi, ekosistemi bu istilacı türden korumak konusunda yardımcı olabilir. 

Fatty Acid Composition of Lagocephalus sceleratus (Gmelin, 1789) (Osteichthyes: Tetraodontidae)

Lagocephalus sceleratus is one of the worst invasive species in the Mediterranean Sea migrated from Red Sea and has been spreading throughout the area. The aim of this study is focusing on the potential nutritional use of this species. The long-chain polyunsaturated fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are beneficial for health of humans. A good natural source of these fatty acids is seafood, especially fish. In this study, total lipid content and fatty acid composition of L. sceleratus were determined. Total lipid content of dorsal muscle was found as 1,82 %. Levels of EPA (6,08%) and DHA (15,68%) were found high. These results may mean that muscle of L. sceleratus has good nutritional value. After solving the toxicity problem of L. sceleratus, consuming this species as a food source may help to prevent the ecosystem againts this invasive species.
