MUĞLA İLİ ULA GÖLETİ’NDE BIR TATLISU DENİZANASI: Craspedacusta sowerbii LANKESTER, 1880

Öz

Bir tatlısu hydrozoan olan Craspedacusta sowerbii Lankester, 1880 Muğla ili sınırları içerisinde yer alan Ula Göleti’nde tespit edilmiştir. Göletin üç farklı bölgesinden örneklenen bu türün bolluk değerleri sırası ile 1,8 birey/m³, 2,3 birey/m³ ve 3 birey/m³ olarak belirlenmiştir. C. sowerbii genellikle insan yapımı göl, gölet ve rezervuarlarda daha çok dağılım göstermektedir. C. sowerbii’nin Ula Göleti’nde daha önceleri var olup olmadığına dair bir veriye rastlanmamıştır. Gölette zaman zaman balıklandırma çalışmaları yapılmaktadır. Bu türün Ula Göleti’ne balıklandırma çalışmaları sırasında gelmiş olabileceği düşünülmektedir. Fakat bu konuda kesin bir bilgi bulunmamaktadır.

A FRESHWATER JELLYFISH IN POND ULA, MUĞLA: Craspedacusta sowerbii LANKESTER, 1880

Abstract

Craspedacusta sowerbii Lankester, 1880 is a freshwater hydrozoan, was determined in Pond Ula, which is located in Muğla province. This species was sampled from three different areas with 1,8 ind./m³, 2,3 ind./m³ and 3 ind./m³ abundances, respectively. C. sowerbii generally distributes in man-made ponds and reservoirs. There is no data about C. sowerbii is previously existed in this pond. Stockings are performed from time to time in the Pond Ula. Therefore, it is thought that this species could have come to the pond with stocking. But there is no precise information on this subject.
