【 摘 要 】

The aim of this study is to record the length-weight relationship, relative condition factor (Krel) and relative weight (Wr) for three fish species in Iranian coastal waters of the Caspian Sea. Fish sampling was carried out in the beach seine fishing grounds in autumn and winter seasons for two years (2007 and 2009). 14104 specimens were measured and weighed. The values of the exponent b in the length-weight relationships (LWRs) were 2.8449 forCyprinus carpio,2.8844 forLiza aurataand2.9077 forRutilus frisii kutum. Relative condition factor (Krel) valueswereranged from 1.017±0.002 to 1.071±0.002. In addition, Relative weight (Wr) ranged from0.929±0.002to1.740±0.004.
