Condition factor and length-weight relationships evaluation of 15 Oxynoemacheilus species (Cypriniformes: Nemacheilidae) from Iran

This study was conducted to determine the relationship between length and weight (LWR) of 15 Oxynoemacheilus species i.e. bergianus, O. brandtii, chomanicus, euphraticus, elsae, frenatus, karunensis, kiabii, kurdistanicus, longipinnis, parvinae, persa, marunensis, zagrosensis, zarzianus from Iranian inland waters. LWRs with high coefficients determination were calculated for all species. The values slope parameter (b) ranged 2.225 in brandtii 3.575 euphraticus. Fulton's condition factor (K$_{F}$) 0.673 persa 1.407 kiabili. Relative conditions had a narrow distribution range 0.988-1.009 mean 1.001 ± 0.028. presents first data waters that can be used future studies fisheries stock managements.
