Abstract

Monitoring studies in a particular area after a long period of time can provide opportunities to understand environmental, physical and biological events that have occurred over time. From this point of view, we aimed to reveal ichthyoplankton assemblages in the Çanakkale Strait after 10 year period. Our findings indicated a 3 oC difference in sea surface termperature in the late spring and early winter compared to earlier studies. As expected, the highest mean abundance and biodiversity of ichthyoplankton were found in the late spring-early summer period but they showed rapid fluctuations even in consecutive weeks. Coastal resident species such as Diplodus annularis, Gobius niger, and Spicara maena were found to be abundant. In Çanakale Strait, larvae of mesopelagic species were sampled for the first time in this study. The occurrence of mesopelagic species far from their natal habitat in the northern Aegean deep sea trench may indicate a change in the region's hydrodynamics.

Çanakkale Boğazı’nda İhtiyoplankton Topluluklarının Zamansal Değişimi

Abstract

Belirli bir bölgede uzun süre aradan sonra yapılan izleme çalışmaları zamanla gerçekleşen çevresel, fiziksel ve biyolojik olayları anlama fırsatı sunar. Bu amaçla, 10 yıl aradan sonra Çanakkale Boğazı ihtiyoplankton topluluğunun ortaya konması amaçlanmıştır. Deniz suyunun beklenenden yaklaşık 3 derece geç ısındığı ve geç soğuduğu belirlenmiş, ancak bu durumun ihtiyoplankton kompozisyonuna etki etmediği tespit edilmiştir. Beklendiği gibi en yüksek ihtiyoplankton bolluk ve biyoçeşitliliği ilkbahar sonu-yaz başı döneminde görülmüş ancak birbirini takip eden haftalarda bile önemli dalgalanmalar tespit edilmiştir. Diplodus annularis, Gobius niger ve Spicara maena gibi kıyısal yerleşik türlerin daha baskın hale geldiği belirlenmiştir. Mezopelajik Derinsu larvaları ilk kez bu çalışmada Çanakkale Boğzı’nda örneklenmiştir. Bu türlerin varoluş alanı olan Kuzey Ege derin deniz çukurundan bu kadar sürüklenmiş olmaları, bölge hidrdinamiğinin değiştiğini göstermektedir.
