Current taxonomy of western Eurasian trout leaves a number of questions open; it is not clear to what extent some species are distinct genetically and morphologically. The purpose of this paper was to explore phylogeography and species boundaries in freshwater and anadromous trout from the drainages of the Black and the Caspian Seas (Ponto-Caspian). We studied morphology and mitochondrial phylo...
Population genetic structure of stellate sturgeon (Acipenser stellatus) in 197 adult specimens from four fishery regions along the Iranian coastline of the southern Caspian Sea was investigated using microsatellite markers. Out of 15 microsatellite primers, 11 loci were produced, in which 10 of them were polymorphic and 1 was monomorph. Totally, 184 alleles were identified and on average 13.1 a...
Forecasting of sea level fluctuations is a suitable tool for comprehensive management of the sea and the protection of coastal areas. On the other hand, application of time series analysis for forecasting purposes has been evaluated to be very appropriate. Therefore, two time series consisting monthly measured sea level data were used in the present research. The data have been recorded at two ...
The aim of this study was to design and develop a three-dimensional numerical baroclinic model with the ability to accept complex bottom topography and variable wind in space and time to investigation wind-induced current at 10 layers in the south Caspian Sea. The finite difference method Was used for numerical solution of the primitive equation in spherical Sigma pressure coordinate system on ...

The present study was conducted on the comparison of morphometric and meristic factors among Alosa caspia (Eichwald, 1838) populations in the southern Caspian Sea basin. A total of 285 Alosa caspia specimens were caught from three localities, from west to the east of Caspian Sea including Guilan (Bandar Anzali), Mazandaran (Sari) and Golestan (Miankale) provinces. Thirty morphometric and ten me...
Background: Marine products, especially fish, play an increasingly significant role in human diets and health. This research evaluated the concentrations of cadmium, lead, chromium, and nickel in liver and muscle tissues of Rutilus frisii kutum along the Caspian Sea coasts of northern Iran. Methods: Thirty samples of fishes were taken from five stations (Astara, Rezvanshahr, Anazali, Ramsar, a...
The fouling barnacle Amphibalanus improvisus is a cosmopolitan biomonitor of trace metal bioavailability in coastal waters of reduced salinity such as estuaries or the Baltic Sea. Bioavailability of Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn to A. improvisus was investigated in July 2014 at 15 sites along the Iranian coast of the understudied, yet biologically unique, Caspian Sea. In gene...
Understanding the population structure and level of genetic diversity wild populations is fundamental for appropriate stock management species conservation. The common carp ( Cyprinus carpio ) one most important bony fish throughout Southern coastline Caspian Sea, but captures this have seen a dramatic reduction during last decade. As consequence, restocking program has been put in place to mai...
