- Аннотация: •Biodiversity conservation is one of the global concerns, so the comprehensive study of diversity and its possible risks are recognized as a tool for natural resource management. This study was carried out to investigate the diversity and abundance of fishes in the Masule River, the southern Caspian Sea basin. Samplings were carried out seasonally during 2021-2022 using an electrofishing device in 5 sampling sites from 7 km below Masule City to Chamesghal. A total of 20 fish species belonging to 11 families were identified, and the Leuciscidae and Cyprinidae families were the most diverse with 6 and 4 species, respectively. Of these, 15 native species and 5 exotic species were found, and in terms of habitats, 16 freshwater, 2 migratory, and 2 species with two forms living in the Sea and River were found in the studied area. The fish species abundance from upstream to downstream increased from 5 to 16 species. Also, their abundance fluctuated according to the sampling sites in different seasons and these fluctuations existed to a lesser extent between the sites in the whole period. Generally, Capoeta razii, Alburnoides samiii, and Ponticola iranicus accounted for the highest numbers, 31.3, 26.2, and 25.4%, respectively. In conclusion, this river has a small variety of migratory fish species, and it is suggested to make a fishway, especially on the Lulman Dam, so that the migratory fishes can regenerate their generation naturally.
