Main Article Content


The length-weight relationships, (LWRs) were calculated for 14 fish species belonging to five families (Cyprinidae, Cobitidae, Nemacheilidae, Salmonidae, and Gobiidae) collected from the Tajan River, north of Iran. Significant length-weight relationships with high correlation coefficients were found for all species.
