| چکیده [English] | ||
| The morphological comparison of five populations of Mosul bleak (Alburnus mossulensis Heckel, 1843) was done using Elliptic Fourier analysis. For this porpose a total of 219 specimens were caught from Tigris basin (Gamasiab, Karoon, Kashkan, Khersan and Sepidbarg Rivers) using electrofishing. The fish were photographed from left sides using a digital camera and the outline curve was digitized using TpsDig2 software and resampled to 150 equal distanced landmarks. The outline curveswere converted to a readable file format for EPA analysis using EFAWIN software and EFA analysis was done opting 17 shape harmonics with 2 constants and four coefficients per harmonic and non-shapeddata were removed usin general Procrustes analysis. The principal component analysis (PCA) and Manova/CVA were used for morphological comparison in PAST software. The results showed significant shape differences between populations but Sepidbarg population (pand Sepidbarg populations were distinguishable having a fusiform shapedbody and the other three other populationswere distinguishable based on a shorter caudal peduncles. The present study proved the potential of the geometric morphometrics (outline curves) for recognizing various populations of the Mosul bleak. | ||
