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...
This study evaluated the possibility of VNN occurrence and the effects of Chlorella vulgaris on immune parameters before and after exposure to Viral Nervous Necrosis virus in Caspian Sea salmon (Salmo trutta caspius). Fish were divided into 4 treatments with three replicates. Treatments included one control group and three experimental groups (T1, T2 and T3). Fish in control group, T1, T2 and ...
Remote measurements of different environmental parameters received during last 30 years are used for the synthesis of a Complex Simulation Model (CSM) describing the combined water regimes of the Aral-Caspian System (ACS) including the consideration of aquatic and climatic natural processes. The problem of stabilizing the sea levels of these two water bodies is modelled and a solution obtained ...
This memo addresses the general prospects for Russia's policy in the Caspian Sea, particularly in light of the ongoing financial crisis and domestic political turmoil. After touching on uncertainties regarding the Caspian's significance as a source of hydrocarbon reserves, I will consider Russia's evolving policy preferences and diplomatic relations, environmental issues, and the broader politi...
The Caspian Sea is the world’s largest inland sea. Physiographically it is unique. It is the most productive body of water in the world1 and the only one that preserves the geno-fund of the sturgeon, the source of almost all the black caviar produced. About 10 million people live around the Caspian Sea and the occupations of many of them are connected with the sea, and first of all with fishing...
Background: Amylin and Salmon Calcitonin belong to the calcitonin family of peptides and have high affinity binding sites in the rat spinal cord. The aim of this study was to characterize receptors for Amylin and Salmon Calcitonin functionally in the spinal cord of rats. We assessed the expression of c-Fos in response to intraplantar formalin in the lumbar regions of the spinal cord in consciou...
Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
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...
Kouraev et al. 2003: Polar Research 22(1), 43–50 A stable and strong ice cover forms during winter months in the Aral Sea and northern part of the Caspian Sea. 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 ...
