This study aims to identify the current fish species of Lake Çıldır. Fish sampling was conducted at three stations with high representativeness of the lake, in May 2024, using gill nets with the assistance of local fishermen. The results of the sampling and reviewing literature the presence of 17 species (Acanthobrama marmid, Alburnoides eichwaldii, Alburnus filippii, Barbus cyri, Capoeta capoeta, Carassius carassius, C. gibelio, Chondrostoma cyri, Cyprinus carpio (both native and introduced forms), Leuciscus aspius, Luciobarbus capito, L. mursa, Oncorhynchus mykiss, Oxynoemacheilus brandtii, Pseudorasbora parva, Salmo murathani and Squalius turcicus) were revealed in the lake. Lake Çıldır is a significant freshwater ecosystem with considerable ecological, economic, and cultural importance for Anatolia. However, given the various threats to the lake, urgent and effective measures are needed for its conservation. This study presents the updated fish fauna of Lake Çıldır and discusses recommendations for the health and conservation of the lake. By compiling existing information on the lake's ecosystem, the study aims to highlight the biodiversity of the lake and the environmental factors impacting it.

Çıldır Gölü'ndeki Balıkların Güncellenmiş Değerlendirmesi: Kapsamlı Bir Çalışma ve Koruma Önerileri

Öz

Bu çalışma, Çıldır Gölü'nün mevcut balık türlerini belirlemeyi amaçlamaktadır. Balık örneklemesi, yerel balıkçıların yardımıyla Mayıs 2024'te, gölü yüksek düzeyde temsil eden üç istasyonda, ağlar kullanılarak gerçekleştirilmiştir. Örnekleme ve literatür incelemeleri sonucunda gölde 17 türün (Acanthobrama marmid, Alburnoides eichwaldii, Alburnus filippii, Barbus cyri, Capoeta capoeta, Carassius carassius, C. gibelio, Chondrostoma cyri, Cyprinus carpio (hem yerli hem de ithal formlar), Leuciscus aspius, Luciobarbus capito, L. mursa, Oncorhynchus mykiss, Oxynoemacheilus brandtii, Pseudorasbora parva, Salmo murathani ve Squalius turcicus) varlığı ortaya çıkarılmıştır. Çıldır Gölü, Anadolu için önemli bir tatlı su ekosistemi olup, ekolojik, ekonomik ve kültürel açıdan büyük bir öneme sahiptir. Ancak, göle yönelik çeşitli tehditler göz önüne alındığında, acil ve etkili koruma önlemlerine ihtiyaç duyulmaktadır. Bu çalışma, Çıldır Gölü'nün güncellenmiş balık faunasını sunmakta ve gölün sağlığı ve korunması için önerileri tartışmaktadır. Çalışma, gölün ekosistemi hakkındaki mevcut bilgileri derleyerek, gölün biyolojik çeşitliliğini ve onu etkileyen çevresel faktörleri vurgulamayı amaçlamaktadır.
