Temporal Variations of the Demersal Fish Community in the Shallow Waters of Çanakkale Strait, North Aegean Sea, during the Course of a Mucilage Event

Bu çalışmanın ana amacı, Çanakkale Boğazındaki sığ su demersal balık topluluğunun zamansal değişime müsilaj olayının etkisini belirlemektir. Eylül 2006 ile Ağustos 2009 yılları arasında ığrıp ile 61 bir farklı demersal balık türü toplanmıştır. Çanakkale sığ sularında musilaj olayı Eylül 2007 ile Temmuz 2008 (müsilaj periyodu) arasında gözlemlenmiştir. Tür bolluğu ve çeşitliliği sıcaklık değişimleri ile ilişkili olarak kış aylarında düşüş göstermekte, bahar ve yaz aylarında ise artış göstermektedir. Mevsimler arasında demersal balık türlerinin kompozisyonu önemli derecede farklılık göstermektedir. Fakat bu farklılık temelde su sıcaklığı değişimleri ile ilişkilidir. Farklı yıllardaki aynı mevsimlerdeki (musilaj öncesi, musilaj esnası ve musilaj sonrası) balık bolluğu ve çeşitliliğinde farklılık olmadığı tespit edilmiştir. Sonuç olarak, musilaj olayı sırasında sığ su örneklemelerimizden elde edilen balık topluluğu verileri Çanakkale Boğazı sığ sularındaki demersal balık topluluklarının tür zenginliği ve bolluğunda önemli bir değişiklik olmadığını göstermektedir

Kuzey Ege Denizi Çanakkale Boğazı Sığ Sularındaki Müsalaj Olayı Esnasında Demersal Balık Topluluğunun Zamansal Değişimi

The main aim of this study was to determine the mucilage event effect on the temporal variations of the shallow water demersal fish community in the Çanakkale Strait. Sixty-one different demersal fish species were collected with a beach seine between September 2006 and August 2009. Mucilage event was observed between September 2007 and July 2008 (mucilage period) in the shallow waters of Çanakkale Strait. Species abundance and richness decreased in winter and increased in spring and in summer and was related to water temperature variations. Demersal fish species composition was significantly different between seasons but these differences were mainly related to water temperature variations. For the same seasons in different years (pre-mucilage, during mucilage, and post-mucilage), no differences of fish abundance and species richness were evident. In conclusion, the fish community data from our shallow water samplings during the course of a mucilage event does not suggest any significant change in the abundance and species richness of the shallow water demersal fish assemblage in Çanakkale Strait
