2 Abstract: Length-weight and length-length relationships were derived for Capoeta capoeta intermedia (Osteichthyes: Cyprinidae), in Dalaki River Bushehr, in South of Iran. Sampling was done throughout one Season from October to December 2011 using electrofishing (D.C. at 200-300 V., 50 Hertz frequencies and one anode). Total length and weight ranged from 75.67 to 215 mm and 3.31 g to 90g, respectively. The Length-weight (LWR) and length-length relationships (LLR) were determined according to the power regression model. The b value in the length-weight relationship was significant difference between males and females (t-test, P?0.05). Length-weight relationship showed positive allometric for males as: W=0.07×L (r2=0.93) and negative 3.79
