Fethiye yöresinde (Akdeniz) pelajik Kılıç balığı paraketalarının av verimini arttırmak için kullanılan ışık çubukları üzerine denemeler

Öz

Bu çalışmada, kılıç balıklarının pelajik paraketalar ile avcılığında ışık çubuklarının av verimi üzerine etkisi araştırılmıştır. 20 Eylül 2012 – 31 Aralık 2012 tarihleri arasında Fethiye bölgesinde toplamda on operasyona çıkılmış ve ölçümler tekne üzerinde yapılmıştır. Yakalanan kılıç balıklarının (n=50) genel, ışıklı bölge ve ışıksız bölge olarak ayrı ayrı birim çaba başına düşen av verimleri (CPUE) elde edilmiş ve karşılaştırılmıştır. Genel CPUE 131±22.72 kg/1000 iğne, ışıklı kısımda CPUE 352±61.32 kg/1000 iğne ve ışıksız kısımda CPUE 20±4.76 kg/1000 iğne olarak elde edilmiştir. Operasyonlar süresince paraketada 9 farklı tür yakalanmıştır. Birey sayısı bakımından Xiphias gladius (%81) en yüksek orana sahiptir ve bunu Muraena helena>Coryphaena hippurus≥Ruvettus pretiosus>Carcharhinus plumbeus≥ Lobotes surinamensis>Prionace glauca≥Alopias vulpinus ≥ Isurus oxyrinchus takip etmiştir
