Abstract:

Garra rufa is one of the 73 Garra species of the family Cyprinidae. Scales are used more commonly than any other structure in population dynamic studies, because of their transparency, ease of sampling, and the minimal in-juries caused to the fish during their removal. To discriminate fish from different rivers including Bashar, Behbahan, Gerdab, Kheirabad, Kooshk-e-Bahram, Mazoo, Palangan, Sendegan, Shoor-Abad, and Sirvan Rivers using geometric morphometric analyses of the scale shape, landmark based geometric morphometrics method was used. Seven landmark points were depicted on each scale using the software TpsDig2. After procrustes analyses, landmark data were exposed to principle component analysis (PCA), CVA, and cluster analyses using the past software. The results showed that th-ere were significant scale shape differences among some populations, but most of the samples showed overlapping sh-ape distribution and could not be separated robustly. Among the samples which were analyzed, only the Sendegan and Gerdab river samples did not show significant difference in scale shape compared to all other samples.

تحلیل ریخت سنجی هندسی فلس جهت شناسایی جمعیت های مختلف گونهء garra rufa heckel, ۱۸۴۳

garra rufa یکی از 73 گونۀ جنس garra متعلق به خانوادۀ کپورماهیان است، که عموماً با عنوان دکترماهی شناخته می­ شود. به ­دلیل شفافیت، سهولت نمونه­ برداری، و حداقل آسیب وارد به ماهی در اثر جداکردن فلس­ ها، از آنها بیشتر از دیگر ساختارها در مطالعات پویایی جمعیت استفاده می­ شود. در این مطالعه برای تفکیک نمونه­ های ماهی g. rufa (متعلق به خانوادۀ کپورماهیان) در رودخانه ­های بشار، بهبهان، گردآب، خیرآباد، ...

Diet and feeding indices of Garra rufa Heckel, 1843 in Gheshlagh River, Kurdistan Province

This study was conducted to survey the feeding indices of Garra rufa in Gheshlagh River, Kurdistan Province. Seasonal sampling carried out during spring, summer, autumn and winter of 2018 using electrofishing and cast net with 20 mm mesh size. For diet analysis, 40 number of Garra rufa was used.

Habitat effects on morphological variation of Garra rufa (Heckel, 1843) populations in Iran

Understanding the processes involved in evolution of organisms is a principal topic that has received much attention from the research community. A common way to achieve this is to study the ecological conditions and morphological relationships of taxa. Fish are widely regarded as notable animal models in studies of environmental influence on morphological features given their high environmenta...

تحلیل ریخت سنجی هندسی فلس ماهیان برای شناسایی جنس، گونه و جمعیت ها مطالعه موردی خانواده کپورماهیان (cyprinidae)

شناسایی گونه ها و جمعیت های ماهیان با استفاده از فلس روشی غیر مخرب، سریع و کم هزینه است. از اینرو، این مطالعه با هدف بررسی امکان به کارگیری روش ریخت سنجی هندسی بر پایه لندمارک بر روی فلس ماهیان برای شناسایی سریع گونه ها و جمعیت های ماهیان و مقایسه آن با روش مشابه محیط پیرامونی فلس با استفاده از لندمارک های کاذب به اجرا در آمد. برای این منظور، از فلس های یک جمعیت از سس ماهی بزرگ سر (luciobarbus ...
