Abstract

This study involved the collection of random samples of fish from the Cyprinidae family in the Greater Zab River, Qandil Village, from July 2024 to February 2025. To examine and evaluate the morphometric and meristic parameters, a total of 374 fish specimens were gathered and documented, comprising 11 species, including Arabibarbus grypus (24 specimens), Capoeta damascina (36 specimens), C. umbla (21 specimens), Carasobarbus kosswigi (21 specimens), C. luteus (18 specimens), Cyprinion kais (63 specimens), C. macrostomus (63 specimens), Garra rufa (18 specimens), Luciobarbus barbulus (50 specimens), L. kersin (18 specimens), and Paracapoeta trutta (42 specimens). Two such fields, morphometrics and meristics, are basic disciplines used by researchers attempting to characterize fish morphology and taxonomy. The current study was undertaken to investigate several morphometrics, like total length (TL), standard length (SL), snout length (SnL), fork length (FL), head length (HL), eye diameter (ED), pre-dorsal length (PDL), dorsal fin length (DFL), dorsal fin height (DFH), anal fin height (AFH), anal fin length (AFL), pectoral fin height (Pc FH), pelvic fin height (PFH), caudal fin length (CFL), minimum body length (Mn BL), maximum body length (Mx BL), and some important meristic characteristics. Consequently, our current findings indicate a direct correlation between the total length of cyprinids and all morphometric characteristics. There was little to no variation among species for meristic metrics. Consequently, our current study may be beneficial in the systematic classification and management of Cyprindae species within the region.
