Determination of the Ectoparasite Fauna in Siraz (Capoeta antalyensis) Fish Sampled from the Antalya Region

Abstract

This study was conducted to determine the ectoparasite fauna of Capoeta antalyensis, an endemic fish species native to Antalya region. A total of 360 C. antalyensis specimens were collected from Köprüçay, Aksu Çayı, and Boğaçayı regions between November 2024 and May 2025 and examined thoroughly in the laboratory. Three distinct ectoparasite species were identified: Trichodina spp., Gyrodactylus spp., and Diplozoon spp. The distribution and intensity of the parasites showed significant variation between the sampling regions and periods. Trichodina spp. was more prevalent in Köprüçay and Aksu Çayı, while Gyrodactylus spp. was found at high intensity in Köprüçay and Boğaçayı, especially during the second period. Diplozoon spp. was detected in Köprüçay and Boğaçayı but was absent in Aksu Çayı. These regional and seasonal differences highlight the influence of specific ecological conditions and potential environmental factors on parasite dynamics. This study provides crucial baseline data on the health status of the vulnerable endemic fish C. antalyensis in its natural habitat, which is essential for future conservation strategies and sustainable aquatic health management.

Antalya Bölgesi'nden Örneklenen Siraz (Capoeta antalyensis) Balıklarında Ektoparazit Faunasının Belirlenmesi

Öz

Bu çalışma, Antalya bölgesine özgü endemik bir balık türü olan Capoeta antalyensis'in ektoparazit faunasını belirlemek amacıyla yapılmıştır. Kasım 2024-Mayıs 2025 tarihleri arasında Köprüçay, Aksu çayı ve Boğaçayı'ndan toplanan toplam 360 adet C. antalyensis örneği laboratuvarda detaylıca incelenmiştir. Üç farklı ektoparazit türü tespit edilmiştir: Trichodina spp., Gyrodactylus spp. ve Diplozoon spp. Parazitlerin dağılımı ve yoğunluğu, örnekleme bölgeleri ve dönemleri arasında belirgin farklılıklar göstermiştir. Trichodina spp.'ye daha çok Köprüçay ve Aksu Çayı'nda rastlanırken, Gyrodactylus spp. özellikle 2. dönemde Köprüçay ve Boğaçayı'nda yüksek yoğunlukta bulunmuştur. Diplozoon spp. ise Köprüçay ve Boğaçayı'nda tespit edilmiş, ancak Aksu Çayı'nda hiç görülmemiştir. Bu bölgesel ve mevsimsel farklılıklar, spesifik ekolojik koşulların ve potansiyel çevresel faktörlerin parazit dinamiği üzerindeki etkisini vurgulamaktadır. Bu çalışma, doğal yaşam alanındaki hassas endemik balık C. antalyensis'in sağlık durumu hakkında, gelecekteki koruma stratejileri ve sürdürülebilir sucul sağlık yönetimi için gerekli olan temel verileri sağlamaktadır
