placed in the same cluster, and Behesht-Abad and Afsarabad populations overlap with each other to some extent. It seems that the difference between different habitats in terms of flow intensity, river slope, nutritional conditions and water physics and chemistry is the reason for the difference in populations, which should be investigated in future studies. Considering that the species <i>G. galaxias</i> is native to the drainage basin of the Persian Gulf of Iran and the studies conducted on this species are very few and limited. Therefore, a comprehensive study of this species from different morphological aspects is necessary.</span></span></span><span dir="RTL" lang="AR-SA" style="font-size:11.0pt"><span style="line-height:105%"><span style="font-family:"Times New Roman",serif"></span></span></span></span></span></span></span></div> <div aria-label="Page Break" class="cke_pagebreak" data-cke-display-name="pagebreak" data-cke-pagebreak="1" style="page-break-after:always" title="Page Break" contenteditable="false"></div> ریخت سنجی سنتی, ریخت سنجی هندسی, سینه خراش Geometricmorphometric, Traditionalmethod, Glyptothorax 30 38 http://jair.gonbad.ac.ir/browse.php?a_code=A-10-1095-1&slc_lang=fa&sid=1 Masoomeh Saravani معصومه سراوانی masoomeh.saravani999@gmail.com 10031947532846008298 10031947532846008298 No Department of Fisheries, Faculty of Natural Resources, University of Guilan Sowmeh Sara, Guilan, Iran گروه شیلات، دانشکده منابع طبیعی دانشگاه گیلان، صومعه سرا، گیلان Hamed Mousavi-Sabet حامد موسوی ثابت mosavii.h@gmail.com 10031947532846008299 10031947532846008299 Yes Department of Fisheries, Faculty of Natural Resources, University of Guilan Sowmeh Sara, Guilan, Iran گروه شیلات، دانشکده منابع طبیعی دانشگاه گیلان، صومعه سرا، گیلان Soheil Eagderi سهیل ایگدری soheil.eagderi@ut.ac.ir 10031947532846008300 10031947532846008300 No Department of fisheries and aquaculture, Faculty of Natural Resources, University of Tehran, Karaj گروه شیلات، دانشکده منابع طبیعی، دانشگاه تهران، کرج Adeleh Heidari عادله حیدری adeleheidari14@yahoo.com 10031947532846008301 10031947532846008301 No Department of Fisheries, Faculty of Natural Resources, University of Guilan Sowmeh Sara, Guilan, Iran گروه شیلات، دانشکده منابع طبیعی دانشگاه گیلان، صومعه سرا، گیلان
