Length–weight relationship and condition factor for five fish species in Anzali Wetland and Talar River of the Caspian Sea Basin of Iran

Ali Reza Radkhah, Soheil Eagderi, Hadi Asadi

This study includes the Length-weight Relationship and Fulton’s Condition Factor of five species from the Caspian Sea basin. A total of 161 specimens were collected from the Anzali wetland and Talar River of the Caspian Sea basin in autumn, 2015 using electrofishing device. The specimens were ranged 4.55-23.04 cm in total length and 0.50-39.87 g in total weight. Based on the results, the values of ‘b’ ranged between 2.68 (C. auratus) and 3.14 (S. cephalus) with a average of 2.91 and the r2 values greater than 0.93 showing a highly significant relationship. The results revealed that the growth type of S. cephalus and H. leucisculus were positive allometry (b>3), and those of B. cyri, C. gracilis and C. auratus negative allometry (b<3). In the present study, the condition factor was found to be between 0.078±0.042 (Mean ± SD) to 1.041±0.112 (Mean ± SD). It was highest in H. leucisculus in and lowest for C. gracilis (0.078). This study provided some basic information of five studied species for fishery biologists in Iran.
