Study of Spirlin fish populations (Alburnoides eichwaldii) using morphological traits in rivers of Golestan province

The aim of this study was to investigate the possibility of isolating study stocks of spirlin populations (Alburnoides eichwaldii) using morphometric traits in rivers of Golestan province, between three regions of Zarrin Gol, Mobarakabad and Dasht in spring 2016. For this purpose, first 45 samples of tailoring fish were caught, then Morphological traits were measured using a caliper with an accuracy of 0.01 mm. In morphological traits, the possibility of separating the two reserves was studied from the principal component analysis method. The present study showed that the samples were separated in three areas, which could be due to habitat conditions and bed material. In general, similar studies for rational and efficient management of fisheries and protection of biological resources and genetic resources, identification of storage structure a species of fish native to each region is recommended.
