Fishes were captured by fixed fishing net and transferred to laboratory of veterinary medicine of Islamic Azad University, Kazerun Branch and identified by key identification after biometry. The results showed that 13 species belonging to four families existing in the Beshar River which including: Garra rufa, Cyprinion macrostomum, Barbus barbulus, Capoeta damascina, Capoeta barroisi, Capoeta trutta, Capoeta capoeta, Alburnus atropatenae, and Chondrostoma regium from cyprinidae, Oncorhynchus mykiss from salmonidae, Glyptothorax silviae from sisoridae and two species Turcinoemacheilus kosswigi and Paracobitis malapterura from nemacheilidae. The frequency of fishes showed that G. rufa had highest percentage of frequency (23.49) and T. kosswigi and P. malapterura had lowest percentage of frequency (0.13). Cyprinidae including 9 species and 96.99 frequencies had highest percentage of frequency among the captured fish. There was no significant relationship between fish frequency and season sampling (p>0.05). The result is that in all fresh waters of the country, the predominant population of fish belonging to cyprinid fish.
