Within species, Capoeta damascina and Squalius lepidus have most and least frequency with 46.3 and 0.2 percent form total number of fish specimens. The results indicating Bazoft river ecology in addition to the provision canvas species possess valuable fish such as Brown trout and other species of economic value. Due to a variety of ecological conditions in Bazoft River, the results indicating existence of three endemic fish species in this river with some valuable species like Salmo trutta and some other commercially valuable species.
