AbstractIntrodouction: In this study we investigated morphological structure of Cyprinidae fish, kutum(Rutilus frisii kutum Kamenskii, 1901) in Caspian Sea using truss network system.Methods: Samples were collected from two beach seine and gill net fisheries cooperations located intwo main fishing areas of this species in the western (Bandare-Astara) and the eastern (Bandare-Kiyashahr) shore of Guilan province. Truss distance as well as eye diameter, interorbital, total length,fork length width of 23 samples were measured in ichthyological research laboratory.Findings: Our results by using Statistical analysis (One-way ANOVA) for morphologicalcharacteristics revealed that 14 morphological traits showed significant differences that showedrelatively high phenotypic diversity among samples in the two kutum populations. Morphologicalcharacters including: total length, standard length, eye diameter and landmark distances including:dorsal first spine and pectoral fin, snout and pelvic fin, the upper branch of caudal fin and the lowerbranch of caudal fin, the first upper branch of caudal fin and the last soft branch of pelvic fin, the lastsoft branch of dorsal fin and the first spin of pelvic fin, the last soft branch of dorsal fin and the upperbranch of caudal fin, the first lower branch of caudal fin and the last soft branch of pelvic fin, theposterior part of pelvic fin and the last soft branch of dorsal fin, the first upper branch of caudal finand the first spin of pelvic fin, snout and basement membrane gill and the first spin of dorsal fin andbasement membrane gill. In principle, any measured distances between landmarks may serve ascharacters for morphometric analyses. We described methodologically a geometric protocol forcyprinid fish species morphological character measurements, the truss network system, which1- MSc in Fisheries Science, Fisheries Department, Gorgan University of Agricultural Sciences and NaturalResources.
