Çanakkale boğazı ve Yöresinde İstilacı-Ekonomik bir gastropod Rapana venosa (Valenciennes, 1846): Biyoekolojisi ve avcılığı

Yayılmacı bir oluklu deniz salyangozu olan Rapana venosa (Valenciennes, 1846) Karadeniz'de Novorossiysky Körfezi'nden (Rusya) ilk kez 1946 yılında kaydedilmiştir. Yine (Gelibolu) Çanakkale Boğazı'nda 1994 yılından beri avcılığı yapılmaktadır. En yakın populasyonların olduğu Karadeniz'den hem gemicilik faaliyetleri hem de doğal yayılımcı olarak bu bölgeye girdiği muhtemeldir. R. venosa, Mytilus galloprovinciaiis (Lamarck, 1819) ve Pecten jacobaeus (Linnaeus, 1758) gibi ekonomik önemli çift kabuklu yumuşakçaların üzerinde beslenen bir predator tür olarak bilinir. Özellikle, bu bölgede midye yatakları üzerinde beslenmektedir. Avcılığı tüm yıl boyunca nargile ve tüplü dalışlar ile serbest bir şekilde yapılmaktadır.

An invader-economical gastropod Rapana venosa (Valenciennes,1846)in Çanakkale and adjacent regions

Abstract: An invader-economical gastropod Rapana venosa (Valenciennes, 1846) in Çanakkale and adjacent regions. An invasive commercial, veined whelk Rapana venosa (Valenciennes, 1846) is first recorded in 1946 around Novorossiysky Bay (Russia), Black Sea. This gastropod has been collecting since 1994 in front of Gelibolu (Çanakkale, Türkiye). It is possible that they enter this region from Black Sea where the nearest population survive through both shipping activities and natural dispersion. R. venosa is known as predatory gastropod which kill impotant commercial bivaves such Mytilus galloprovinciaiis (Lamarck, 1819) and Pecten jacobaeus (Linnaeus, 1758). R. venosa especially, feeds on the mussels beds in this region. They are freely hunted by scubadiving and air supply diving systems all year long.
