Abstract In this study, in order to identify the fish fauna of Beshar River located in Kohgiluyeh and Boyer-Ahmad province, sampling was performed in summer and winter seasons during 2014. 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.

In order to study and identify macrobenthic invertebrates’ fauna of Dadin Spring in Kezerun, Fars south-west, Iran was conducted from April, 2014 to March, 2015. Benthic samples were collected from five different stations of spring including: center, north, south, west and east. Sediment was performed by using Van Veen Grab. After washing the sediment to avoid spoilage, organisms were fixed with 1% formalin and then macrobenthic invertebrates were identified based on key identification. The results showed that three phyla of macrobenthic invertebrates were diagnosed in the Dadin spring which these three phyla including Arthropoda, represented by seven genera: Epitheca sp., Argia sp., Chironomus sp., Chysops sp., Hydropsyche sp., Potamon sp., Caridina sp.. Annelida represented by two genera, Uncinais sp. and Lumbriculus sp. and Mollusca represented by four genera of gastropods including Theodoxus sp., Monacha sp., Melanopsis sp. and Melanoides sp.. Mollusca dominated the macrobenthic invertebrates with a total abundance of 48% and Annelida were the least abundant, 15.5% by number. Although the abundant of Arthropoda was less than Mollusca (36.75%),but the diversity of Arthropoda was more than others. One-way Aonwa showed that there was significant relationship between collected samples and season (P≤0.05) while this relationship was not seen between collected samples and sampling station(P>0.05).
