The results indicated that the Tonekabon river fishes belong to 5 families as Salmonidae, Cyprinidae, Athenrinidae, Cobitidae and Gobiidae. The most frequency (89.4 % ) and distrubution of Salmonidae situated in upstream of the rivers belong to salmo trutta fario. From Cyprinidae, Alburnoides bipunctaus with 26.4%, Capoeta capotea with 19.9% and Barbus lacerta with 5.9% had the maximum frequency and distribution along the rivers comparing to other species. From Gobiidae, Neogobius melanostomus with 8.3% and from Cobitidae, Cobitis taenia with 7.3% had the maximum frequency.
