Length-weight and length-length relationships of four species ( Barbus lacerta Heckel, 1843), Oxynoemacheilus angorae ( Steindachner, 1897), Squalius lepidus ( Heckel, 1843) and Pseudorasbora parva ( Temminck & Schlegel, 1846) from the Sirwan River (western Iran)

The study describes the length-weight and length-length relationships for three cyprinid species, namely Barbus lacerta, Squalius lepidus and Pseudorasbora parva, and a balitorid species, Oxynoemacheilus angorae from the Sirwan River (located in Kurdistan and Kermanshah provinces, Iran. This study presents the first reference on LWR for most of the species in their distribution range. [ABSTRACT FROM AUTHOR]
