Özet

Monitoring studies, inventory programs, and distribution data are needed to manage invasive species and to develop quantitative ecologic, economic, and social impact assessment which would provide valuable insights that can help direct efforts to contain invasive species and prevent their distribution. In this study, carried out within the scope of the EU funded IASON Project (detection and monitoring of alien and invasive species in the Black Sea Delta protected areas), the presence of invasive fish species in the Kızılırmak Deltaic Area, which is the largest wetland and Ramsar area of the Black Sea Region of Turkey, was investigated. Fish populations in three lakes, located in the Kızılırmak Deltaic Area, were sampled by gillnets and electrofishing in Spring and Summer. Sampled fish were genetically identified at species level by analyzing COI gene region of mtDNA. In total, 17 different fish taxa were identified at species level. Among which, four invasive species; Carassius gibelio, Syngnathus abaster, Pseudorasbora parva, and Gambusia holbrooki were identified and their presence were confirmed in all of the sampled lakes.
