(Heckel,

Oxynoemacheilus germencicus
(Erk’akan,

et

1991);
Oxynoemacheilus hazarensis
Freyhof
et
Özuluğ,

Oxynoemacheilus insignis
(Heckel,
1843);
Oxynoemacheilus
kaynaki Erk’akan, Özeren et Nalbant, 2008; Oxynoemacheilus mediterraneus (Erk’akan, Nalbant et Özeren, 2007);
Oxynoemacheilus namiri (Krupp et Schneider, 1991); Oxynoemacheilus nasreddini Yoğurtçuoğlu, Kaya et Freyhof, 2021; Oxynoemacheilus
paucilepis (Erk’akan, Nalbant et Özeren, 2007); Oxynoemacheilus samanticus (Bănărescu et Nalbant, 1978); Oxynoe-
macheilus seyhanensis (Bănărescu, 1968); Oxynoemacheilus seyhanicola (Erk’akan, Nalbant et Özeren, 2007); Oxynoemacheilus
simavicus (Balik et Bănărescu, 1978); Oxynoemacheilus theophilii Stoumboudi, Kottelat et Barbieri, 2006; Oxynoemacheilus tigris
(Heckel, 1843); Oxynoemacheilus veyselorum Çiçek, Eagderi et Sungur, 2018. Based on the results, the growth coefficient values (b)
ranged from 2.770 (O. argyrogramma) to 3.285 (O. theophilii) with an R
2
estimate greater than 0.91. Fulton’s condition factor (K
)
of the studied fishes ranged from 0.598 (O. insignis) to 1.07 (O. nasreddini ). Relative conditions (K
) were found to have a narrow
distribution range (0.856–1.014 with a mean of 1.005). The form factors of these species were calculated between 0.006 and 0.14,
with a mean and median value of 0.01. This study represents the first reports of LWRs parameters for 22 species, new maximum total
length data were bigger than given in FishBase for 21 species, and first species listing for maximum total length for seven species.
The findings of this study provide useful information for further fisheries management and fish population dynamic studies.
