Freshwater fishes have great importance in freshwater ecosystems and play various roles in ecosystems. Measuring the biodiversity of these fish is a key focus in many ecological studies. The measurement of biodiversity depends on the type of data and the study objectives and various methods have been developed to calculate it. This study aimed to calculate the biodiversity of fish in the Lake Urmia basin using fractal analysis based on fish presence data. Additionally, the calculated fractal dimension was obtained with simulation, which determined the range of fractal dimension variations. The results indicated that the fractal dimension of freshwater fish in the Lake Urmia basin is at an average level. Considering the drying of Lake Urmia, these results suggest that the biodiversity of these fish is highly sensitive and may tend towards negative changes. The average level of biodiversity among fish in the basin can also indicate an average level of population connectivity and gene flow. The methodology used to study biodiversity and its changes can be applied to other aquatic ecosystems and watersheds. These findings highlight the importance of conservation efforts and further research to mitigate potential negative impacts on freshwater fish populations and their ecosystems.
