Abstract

Zooplanktonic organisms play a key role in shaping the pelagic food web and realizing of biochemical cycles. It is important to have knowledge about zooplankton biomass and its distribution in predicting their contributions to the organic matter and energy flow in the ecosystem. In this context, zooplankton samples were collected in April and October 2008 withWP-2 plankton net (200µm) at the stations identified along the single line in the Turkish Straits System. The spatial and vertical distribution of the biomass values from these samples was determined in the epipelagic region and the lack of information about this issue in the region was tried to be eliminatedThe mean standing stock of mesozooplankton in TBS differed spatially and vertically. Mesozooplankton biomass was generally concentrated in the surface mix layer in spring and decreased with depth. In the autumn, the transition layer was found to be higher in terms of mean mesozooplankton biomass values. These values, which are generally high in the straits, decreased considerably in the inner regions of the Marmara Sea, especially in the northwest. Although the station depth, depth layers and the amount of dissolved oxygen affected the biomass distribution in the region, it is thought that the musilage event reported during the sampling period largely masked the important parameters such as temperature and salinity.

Özet

Zooplanktonik organizmalar pelajik besin ağının şekillenmesinde ve biyokimyasal döngülerin gerçekleşmesinde anahtar rol oynamaktadır. Zooplankton biyokütlesi ve dağılımı hakkında bilgi sahibi olmak, bu canlıların ekosistemdeki organik madde ve enerji akışına katkılarını tahmin etmek için önem arzetmektedir. Bu bağlamda, 2008 yılının Nisan ve Ekim aylarında Türk Boğazlar Sistemi’nde tek hat boyunca belirlenen istasyonlardan WP-2 plankton kepçesi (ağ göz açıklığı 200µm) ile zooplankton örnekleri toplanmıştır. Bu örneklerden ölçülen biyokütle değerlerinin epipelajik bölgedeki alansal ve dikey dağılımı belirlenerek bölgedeki bu konuyla ilgili bilgi eksikliği giderilmeye çalışılmıştır. TBS’de ortalama mesozooplankton mevcut stoğu alansal ve dikey olarak farklılık göstermiştir. Mesozooplankton biyokütlesi genel itibariyle ilkbaharda yüzey karışım tabakasında yoğunlaşmış, derinlik ile birlikte azalmıştır. Sonbahar periyodunda ise geçiş tabakası ortalama mesozooplankton biyokütle değerleri bakımından daha yüksek bulunmuştur. Genel olarak boğazlarda yüksek olan bu değerler, Marmara Denizi’nin iç bölgelerinde özellikle kuzey batısında oldukça düşmüştür. Bölgedeki biyokütle dağılımında istasyon derinliği, derinlik tabakaları ve oksijenin miktarı etkili olmakla birlikte, örnekleme periyodu boyunca gerçekleştiği bildirilen musilaj olayının sıcaklık ve tuzluluk gibi önemli parametrelerin etkisini büyük ölçüde maskelediği düşünülmektedir.
