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...

This study evaluated the feasibility of a drowning intervention package in northern Islamic Republic of Iran. A quasi-experimental design used pre- and post-observations among residents and tourists in water-recreation beach areas of intervention and control regions by the Caspian Sea and in residents near the Caspian Sea coastline. The fatal drowning rate in the studied resident population in ...

The ecology of the Sea are being endangered due to several issues such as petroleum extraction, river and sea pollutions, water level rise, biological...

The Ponto-Caspian amphipod Obesogammarus obesus (Sars, 1894) was first recorded in the Rhine River near Koblenz, Germany in October 2004. Additional records of small numbers of O. obesus from the same location in 2005 and 2006 indicate that this alien species may have become established in the central section of the Rhine River. Ship transport via the Main-Danube Canal, connecting the Danube ba...

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...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

alburnus chalcoides , caspian shemaya, is found in the river systems of the aral, black and caspian sea basins and is an economically valuable cyprinid from the southern caspian sea. this species has been reported as near threatened species in this basin due to damming, over and illegal fishing, destruction of its spawning grounds and water pollution. the caspian shemaya is an important species...
