Üstten girişli yuvarlak tel sepetlerin hayelet avcılık açısından incelenmesi

Hayalet avcılık, deniz ve iç sularda çeşitli nedenlerden dolayı kaybolan, uzatma ağları ve balık tuzakları gibi av araçlarının, avcılığa devam etmesi sonucunda ortaya çıkan istenmeyen balıkçılık durumudur. Bu çalışma, ticari yuvarlak balık sepetlerinin hayalet avcılık durumlarının incelenmesi için gerçekleştirilmiştir. Çalışmada, 4 adet üstten girişli yuvarlak tel sepet, Kasım 2002 -Mart 2003 tarihleri arasında, İzmir Körfezi Karantina adası mevkiinde, doğal bir resif alanına yerleştirilmiştir. Tuzakların avcılık durumu dalış gözlemleri ile izlenmiştir. Denemelerde, tuzağın içine giren balıkların, yoğunluğa bağlı olarak 10. günden sonra kaçmayı öğrendikleri bulunmuştur. Bir aylık dönemden sonra sepetler içinde herhangi bir avcılık gözlenmemiştir.

An investigation on ghost fishing of circular fish traps used in Turkey

An investigation on ghost fishing of circular fish traps used in Turkey. Ghost fishing is an unwanted fishing situation which arises from the continuity of catching fish by the set net and fish traps after being lost in the marine and fresh water. This study was carried out to determine the ghost fishing situation of commercial circle fish traps. In this study, four circular traps were deployed near to a reef area, Karantina Island, Izmir Bay. between November 2002 and March 2003. Traps were observed by daily diving surveys. Depending on fish density, fish learned to escape from the traps' openings or from the bar gaps after the 10th day. Ghost fishing was not observed after the first mount.
