Abstract

Abstract: : This study was carried out between September 2007 and April 2008 in the Aegean Sea with an experimental longline. Traditional baits such as Sardina pilchardus and Solen vagina were used with Sepietta sp. which is a discarded species from Aegean Sea demersal trawl fishery. 438 individuals belonging to 6 families were obtained and they totally weighed 43.1 kg. It was determined that almost half of the specimens were captured by Sepietta sp. Furthermore individuals caught by this alternative bait composed 45% of the total catch in terms of weight. Results showed that Sepietta sp. was the most efficient bait among all baits used in the study. The use of this species as a bait in longline fishery has also another importance from the perspective of evaluating a trawl discarded species.

Keywords: Longline, bait, Sepietta sp., small scale fishery

Abstract

Bu çalışma Eylül 2007-Nisan 2008 tarihleri arasında deneysel amaçlı hazırlanmış bir paragat takımıyla Ege Denizi’nde gerçekleştirilmiştir. Geleneksel yemler olan Sardina pilchardus ve Solen vagina, Ege Denizi demersal trol avcılığında ıskarta edilen bir yem olan Sepietta sp. ile birlikte kullanılmıştır. Altı familyaya ait toplam 438 birey yakalanmış ve toplam ağırlıkları 43,1 kg olarak bulunmuştur. Yakalanan bireylerin yarısına yakın kısmı Sepietta sp. ile yakalanmıştır. Bununla beraber bu alternatif yem ile yakalanan bireyler toplam avın ağırlık olarak %45’ini oluşturmuşlardır. Sonuçlar Sepietta sp.’nin tüm yemler içinde en etkili yem olduğunu göstermiştir. Bu türün paragat balıkçılığında yem olarak kullanımının, trol avcılığından ıskarta edilen bir türün değerlendirilmesi açısından ayrı bir önemi bulunmaktadır
