To study of morphometric and determining meristic characteristics of Garra rufa in the Bashar River, Kohkiloyeh and Boyerahmad province, 36 specimens were collected using hand and throwing net and subsequently fixed in 10% Formalin solution. 28 morphometric characters of the specimens were measured using a digital caliper with a precision of 0.01 mm. Thereafter, eight countable characters including number of lateral line scales and fin rays (Dorsal, Caudal, anal, pectoral and pelvic fins) using a binocular loop, were studied. A survey of 36 specimens showed that the total length was in the range of 78.05 to 132.21 mm and the standard length in 69.52 to 115.51 mm. About the countable characteristics, the number of spines and soft rays of dorsal fin were in the range of 8 to 11, the number of spines and soft rays of caudal fin in the range 18 to 22, the number of spines and soft rays of anal fin in the range 6 to 8, the number of spines and soft rays of pelvic fins in the range 8 to 12, the number of spines and soft rays of pectoral fins in the range 6 to 9 and the number of scales on the lateral line was determined in the range of 31-37. These results showed high overlap with other studies in Iran. Garra rufa is mostly distributed in Iran rather than other species of Garra and population studies from different localities, can bring up new taxonomic records in association with this Garra and population studies from different localities, can bring
