Post-Soviet legal governance regime of Caspian Sea e the largest inland body of water on earth e remains a source of conflict among the five coastal states of Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. Although different division methods have been suggested for sharing the sea and its valuable resources, the actual gain of the countries is unclear as the proposed methods focus eith...

The search for renewable energy supplies today’s global demand, particularly ocean wave coastal areas, has become undeniably widespread in the last two decades. Caspian Sea represents an immense opportunity using energy, especially considering its long shoreline. In this study, locations with maximum potential were chosen central, eastern, and western zones of Sea’s southern coasts. Accordingly...

This paper focuses on heavy metal distribution patterns in sediments of central Guilan (CG) and east Mazandaran (EM) in the south Caspian Sea coasts, north of Iran. Sediment sub-samples were retrieved from core and surficial samples in different environments of marine and coastal lagoons as well as coastal outcrops. Inductively Coupled Plasma Mass Spectrometry and Atomic Emission Spectrometry (...

The sturgeon stock assessment was performed to aim at estimation of absolute and relative abundance and determination of species composition at lower 10 m depths using the Si-Sara2 RV vessel in the Iranian coasts of the Caspian Sea in Guilan, Mazandaran and Golestan provinces during 6-30 September 2011-2012. In this study, 40 stations were selected on the basis of stratified random sampling des...

INTRODUCTION The sturgeons of the Caspian Sea are considered highly valuable species. The Caspian Sea has traditionally been regarded as the sea of sturgeon since it produces more than 90 percent of the world’s caviar. Despite a remarkable decline of sturgeon numbers over recent years, the Caspian Sea still continues to be of considerable importance in sturgeon fisheries. In 1997, the global la...

Legally certified sturgeon fisheries require population protection and conservation methods, including DNA tests to identify the source of valuable sturgeon roe. However, the available genetic data are insufficient to distinguish between different sturgeon populations, and are even unable to distinguish between some species. We performed high-throughput single-nucleotide polymorphism (SNP)-geno...

concentration levels of 16 polycyclic aromatic hydrocarbons (pahs) consisting of naphthalene, acenaphthylene, acenaphthene, fluorine, phenantherene, anthracene, fluor?anthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)p?yrene, dibenzo(a,h)ant?hracene, indeno(1,2,3-cd) pyrene and benzo(g,h,i)perylene were measured in water and sediment samples coll...

a 15-landmark morphometric truss network system was used to investigate the hypothesis of population fragmentation of shad fish alosa braschnicowi borodin, 1904 along the southern caspian sea. a total of 181 a. braschnicowi specimens were caught from six localities, respectively from the west to the east including; astara, rezvanshahr, anzali, tonekabon, sari and miankale. principal component a...
