Abstract

In this study, the starting time of ghost fishing in baited fish traps were determined. Two separate trials using 4 different types of fish traps (foldable, conical, “O” shaped Round and cylindrical) were carried out in the Çanakkale Strait at a depth of 5m between July - December 2013. A total of 12 fish traps (3 for each trap type) were used in the study. Each trial lasted a period of 45 days. Major features of the traps were as follows: the foldable fish trap had “V” shaped inclined funnel; the conical fish trap had a conical entrance from the top; The “O” shaped fish trap had a “V” shaped entrance on the base; the cylindrical trap had a conical entrance on the side. In all trials fresh sardine, black mussel and bread placed in a net bag were used as bait and fixed in the traps. Underwater observations showed that fish entrapped in all trap types escaped from the traps within 8-10 days. Fish mortality was due to accidental entanglement of fish on the mesh material covering the traps or due to predation. Molluscs such as octopuses and squids escaped within 4-7 days whereas crabs suffered from cannibalism or starvation due to their lower escape rates. In conclusion, in the present study while trap ghost fishing for fish and cephalopods were not observed, ghost fishing for crabs were observed and was a factor of entrance design and location on traps.

Abstract

Bu çalışmada, yemli balık tuzaklarında hayalet avcılığına başlama zamanının belirlenmesi amaçlanmıştır. Bu amaçla, Çanakkale Boğazı’nda katlanabilir ve tabandan bağımsız “V” şekilli, üstten konik girişli konik sepet, “O” şekilli sepete tabandan “V” şekilli ve silindirik sepete yandan konik girişli olmak üzere 4 farklı tuzak, 5 m su derinliğinde, Temmuz – Aralık 2013 tarihleri arasında iki farklı deneme gerçekleştirilmiştir. Çalışmada her bir sepet modelinde 3 adet olmak üzere toplamda 12 adet sepet kullanılmıştır. Her bir deneme 45 gün sürmüştür. Denemelerde yem olarak, sardalye eti, kara midye ve ekmek kullanılmış ve bu yemler ağdan yapılmış bir filenin içine konularak sepetlerin içine sabitlenmiştir. Denemeler sonucunda tuzağa düşen balıkların 8-10 gün içinde tuzaktan kaçtığı sonucuna varıldı. Sepetlerde meydana gelen balık ölümleri tuzakların kaplama malzemelerine dolanmalarından ya da predatör saldırıları sonucu meydana geldiği gözlenmiştir. Kafadanbacaklılardan ahtapot ve mürekkep balıklarının 4-7 gün arasında kaçtığı, yengeç gibi kabukluların kaçmayı başaramadığı ve kanibalizmden veya açlıktan öldükleri tespit edilmiştir. Sonuç olarak, denemelerde kullanılan tuzakların balıklar ve kafadanbacaklılar üzerinde hayalet avcılık etkisi olmadığı belirlenmiş, yengeçlerde ise giriş tipine göre ciddi bir hayalet avcılık etkisi olduğu belirlenmiştir.
