Identifying invasive fish species threats to RAMSAR wetland sites in the Caspian Sea region—A case study of the Anzali Wetland Complex (Iran)

摘要: Risk screening tools play a crucial role in identifying potential high‐risk non‐native (NN) fish species. In this study, potentially invasive NN species the Anzali Wetland Complex (AWC), which is located on south coast of Caspian Sea (Iran), were identified using Aquatic Species Invasiveness Screening Kit (AS‐ISK). Twenty‐nine freshwater screened 13 exist AWC and 16 close proximity to it (“horizon” species). Receiver operating characteristic curve analysis showed that AS‐ISK could discriminate reliably between non‐invasive for AWC. Mean threshold scores 3.25 Basic Assessment (BRA) 11.75 BRA + CCA (BRA + Climate Change Assessment), these, respectively, classified 89.7% 86.2% as high risk. The CCA resulted an increase BRA species, suggesting need account future management likely increased invasiveness those under climate conditions. These results suggest prove effective tool fishes other wetlands basin.
