Length-weight and length-length relationships and condition factor of six cyprinid fish species of Zarrineh River (Urmia Lake basin, Iran)

This research was conducted to study the length-weight and length-length relationships and condition factor of six cyprinid fish species viz. Alburnus atropatena , Barbus lacerta , Capoeta capoeta , Carrasius gibelio , Romanogobio macropterus and Pseudorasbora parva from Zarrineh River (Urmia Lake basin, Iran). A total of 188 specimens ranging from 2.9 to 21.4cm in total length and 0.22 to 176g in total weight were collected. Based on the results, the values of b varied between 2.59 for C. capoeta , to 3.26 for A. atropatenae . All length-weight relationships were significant (P 0.98). All linear regressions were highly significant (P<0.05). The result of this study may be useful for biologists and fishery managers.
