Türkiye'de Hirfanlı Baraj Gölü'ndeki Sazanlarda (Cyprinus carpio) Bir Vakada Parazitolojik, Bakteriyolojik ve Virolojik Araştırma

Öz

Bu çalışmanın amacı, 2021 yılının ilkbaharında Türkiye’de Hirfanlı Baraj Gölünde yaşayan sazanlarda görülen ölüm olayının altında yatan hastalık etkenlerine ışık tutmaktı. Bunun için çeşitli parazitolojik, bakteriyolojik ve virolojik araştırma teknikleri kullanıldı. Beş parazit cinsi, Dactylogyrus spp., Myxobolus spp., Eimeria spp., Trichodina spp., Diplostomum spp. 13 adet sazandan izole edildi. Tatlı su balıklarında fırsatçı bakteriyel patojeni olan Aeromonas hydrophila da lezyonlu balıklardan izole edildi. Virüsler tespit edilmedi. Sazanlardaki deri lezyonlarında mantar enfeksiyonlarına rastlandı. İncelenen sazanlardaki hastalık ve ölüm tablosunun kaynağı, bu balıklarda parazitik, bakteriyel ve mantar etkenlerinin birleşik etkisine işaret etmektedir. Hirfanlı Baraj Gölü'ndeki sazanların konaklık ettiği parazitlerin ekolojisindeki dinamikleri daha iyi anlamak için göldeki parazit faunasının mevsimsel değişimleri hakkında daha fazla araştırmaya ihtiyaç vardır.

Parasitological, Bacteriological and Virological Research of Carp (Cyprinus carpio) in a Case in Hirfanlı Dam Lake in Türkiye

Öz

The aim of the present study was shedding light on the disease factors underlying mortality event among common carps inhabiting Hirfanlı Dam Lake in Türkiye in spring of the year 2021. For this purpose various parasitological, bacteriological and virological research techniques were employed. Five parasite genera, Dactylogyrus spp., Myxobolus spp., Eimeria spp., Trichodina spp., Diplostomum spp. were isolated from 13 common carps. The opportunistic bacterial pathogen of fresh water fishes Aeromonas hydrophila was also isolated from wounded fish. No viruses were detected. Fungal infections were encountered in the skin lesions of carps. The source of the encountered morbidity and mortality picture among the studied carps points to the combined action of parasitic, bacterial and fungal agents in these fish. Further investigations on seasonal variations of parasitofauna on the lake are needed for better understanding the dynamics in the ecology of the parasites which are hosted by carps in the Hirfanlı Dam Lake.
