Undoubtedly, during the post-Cold War era, the fields of political competition changed and with the change in the political geography of the Caspian Sea, the Caucasus and Central Asia, as the Soviet Union collapsed and new countries emerged, the field of competition for a change in power balance not only expanded but took on a new form. Economic benefits, diversification of fossil fuels and new...

BACKGROUND AND OBJECTIVES The US Environmental Protection Agency has suggested faecal enterococci as the primary bacterial indicators. Of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. In contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the Caspian Sea possess its o...

Kutum is considered as one of the anadramous species of the Caspian Sea. Due to continuous population decline of the fish since 1975, Iranian fisheries organization started to restock this species. Nowadays, there is growing concern over the effects of restocking on natural populations. For this purpose, population structure and genetic variation of this species in the Iranian coastline of Casp...

Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...

Thousands of Caspian seals (Phoca caspica) died in the Caspian Sea from April to August 2000. Lesions characteristic of morbillivirus infection were found in tissue specimens from dead seals. Canine distemper virus infection was identified by serologic examination, reverse transcriptase- polymerase chain reaction, and sequencing of selected P gene fragments. These results implicate canine diste...

A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon.

The Caspian seal (Pusa caspica) has declined by more than 90% since 1900 and is listed as endangered by IUCN. We made the first quantitative assessment of Caspian seal by-catch mortality in fisheries in the north Caspian Sea by conducting semi-structured interviews in fishing communities along the coasts of Russia (Kalmykia, Dagestan), Kazakhstan and Turkmenistan. We recorded a documented minim...

demonstration of the geomorphological factors in setting the legal regime of the caspian seaintroduction:the caspian sea is the largest water basin which enclosed by land within eurasia continent. the caspian sea is unique in many reasons: the large deposits of oil and gas, valuable fishery resources; including 90% of the world’s stock of sturgeon, important transportation routes; connecting th...
