Abstract

In this study, a traditional longline set used in the lower Sakarya River wasinvestigated. Technical characteristics and usage of the longline set weredetermined. Approximately 25-30% of the fishermen in the lower Sakarya Riveruse this method. Fishermen use the longline set with 30-40 baited hooks bypositioning them between the two banks of the river (30-60 m). Fishermen targetrelatively big individuals, especially, Silurus glanis. However, Esox lucius andsome Cyprinidae species are also caught. The average daily catch is between 5-10 kg and captured S. glanis individuals are between 1-20 kg. To ensuresustainability, catch per unit efforts of this traditional method, and spawning stockbiomass should be monitored.

Özet

Bu çalışmada, Aşağı Sakarya Nehri’nde kullanılan geleneksel bir paraketa takımı incelenmiştir. Paraketa takımının teknik özellikleri ve kullanım şekli belirlenmiştir. Aşağı Sakarya Nehri’nde yaklaşık balıkçıların %25-30’u bu yöntemi kullanmaktadır. Balıkçılar 30-40 adet yemlenmiş kancaya sahip paraketa takımını, nehrin iki kıyısı arasına (30-60 m) konumlandırarak kullanmaktadırlar. Balıkçılar özellikle Silurus glanis olmak üzere nispeten büyük balıkları hedeflemektedirler. Ancak Esox lucius ve bazı Cyprinidae türleri de yakalanmaktadır. Günlük ortalama toplam av 5-10 kg ve yakalanan S. glanis bireylerinin ağırlıkları 1- 20 kg arasındadır. Sürdürülebilirliğin sağlanması için bu geleneksel yöntemin birim çabaya düşen av miktarı ve üreyen biyokütlenin izlenmesi gerekmektedir.
