BACKGROUND Knowledge about the amphistomid fauna in Iranian domestic ruminants depends on the studies conducted almost 30 years ago. The last situation in cattle is introduced here in the provinces in south coast of Caspian Sea. METHODS Amphistomid species were collected from cattle at slaughter houses of the provinces Gilan and Mazanderan in 2010. Median sagittal sections were prepared by th...

we estimated the genetic diversity and population structure of persian sturgeon across six regions of caspian sea along the coast of iran using eight dna microsatellite loci. full genotypes were obtained for 195 individuals of persian sturgeon. significant differences were detected between a. persicus specimens collected from sefidrud river (p≤0.0001) and those collected from the southern fishe...

The invasion of the zebra mussel, Dreissena polymorpha, into North American waters has resulted in profound ecological disturbances and large monetary losses. This study examined the invasion history and patterns of genetic diversity among endemic and invading populations of zebra mussels using DNA sequences from the mitochondrial cytochrome oxidase I (COI) gene. Patterns of haplotype frequency...

The presence of ice cover negatively affects navigation and fi shery condi tions and endangers facilities located on the coast as well as on the shelf, such as oil rigs that have recently been installed in the northern Caspian by Russia ...

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...
