“…Scales of all the nine studied Garra species demonstrated a specific sectioned form, that is, “tetra‐sectioned” type, due to the presence of radii in all four fields of scales (anterior, posterior, and laterals). The “tetra‐sectioned” type has also been reported for the scales of G. shamal (Al Jufaili et al, 2022), G. sharq (Echreshavi, Al Jufaili, et al, 2022), G. rossica (Esmaeili et al, 2012), and G. rufa , G. persica , and G. hormuzensis (Zareian et al, 2021). In addition to these typical characteristics, some morphological variations in the scales of the examined fishes were observed in the overall shape and the focus shape.…”

To evaluate scale morphological variability (shape, size, topological macro‐ and microstructures, ornamentation patterns) of cyprinid fishes, nine species of the genus Garra were selected and their scales from five different body regions were studied by using light and scanning electron microscopy. The scales of the examined species were thin with a central or antero–centrally positioned focus, with no cteni in the posterior part. In addition to these typical characteristics, some morphological variation was observed in the overall shape (irregular round, true oval, round‐triangular, irregular pentagonal, hexagonal, irregular hexagonal, pentagonal, ovoid), and the focus shape. These variations were mainly dependent on the fish lengths and the flank region. Morphological analysis clustered the examined species into two distinct groups. Group I consisted of G. amirhosseini and G. gymnothorax, while Group II has three subgroups, which include G. persica and G. mondica (subgroup I), G. meymehensis, G. rossica, G. nudiventris, G. hormuzensis (subgroup II), and G. rufa (subgroup III). The grouping of the studied Garra species based on the current scale morphological characters and the molecular data was only consistent for G. rossica and G. nudiventris. In addition, in the phylogenetic tree, G. persica, G. mondica, G. amirhosseini, and G. hormuzensis formed a distinct clade. However, these species did not represent close relationships in the dendrogram obtained from the scale morphology. A possible explanation why the grouping of the studied Garra species based on their scale morphological characters does not match their phylogenetic relationships is that most of the scale morphological traits vary depending on the fish size and the location of the scales on the flank. Therefore, except for some traits, that is, central or antero–centrally positioned focus, having no cteni, a specific sectioned form so called “tetra‐sectioned” type, the other examined variables are not useful enough to be used in the taxonomic study of the examined cyprinid fishes. Therefore, scale morphological characters should be used carefully for taxonomic purposes.Research Highlights Shape, size, topological macro‐ and microstructures, and ornamentation patterns of nine species of the genus Garra were studied by using light and scanning electron microscopy.

This study investigate investigated the length-weight, length-length relationships and condition factor of eight fish species collected from Bashar River, Tigris drainage by sampling 341 specimens of Alburnus sellal (Heckel, 1843), Barbus karunensis (Khaefi, Esmaeili, Geiger & Eagderi, 2017), Capoeta aculeate (Valenciennes, 1844), Capoeta coadi (Alwan, Zareian & Esmaeili, 2016), Chondrostoma regium (Heckel, 1843), Garra gymnothorax (Berg, 1949), Glyptothorax galaxias (Mousavi-Sabet, Eagderi, Vatandoust & Freyhof, 2021) and Turcinoemacheilus hafezi (Golzarianpour, Abdoli, Patimar & Freyhof, 2013). The results showed that the b parameter was form 2.41 (in C. aculeate) to 3.88 (in A. sellal) and condition factors ranged from 0.74 (in A. sellal and B. karunensis) to 1.35 (in C. aculeate). The coefficient of determination (r2) in the length-weight and length-length relationships was > 0.83. In conclusion, allometric growth patterns for A. sellal, B. karunensis, G. gymnothorax, and G. galaxias were positive while for C. aculata, C. regium and T. hafezi, and C. coadi presented negative patterns. This study represents the first data for G. galaxias.
