the heavy metals concentrations including zinc, copper, lead and cadmium (zn, cu, pb and cd) in water and sediments in gorgan bay and their accumulation in rutilus frisii kutum, acipenser persicus, rutilus rutilus caspicus and cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. there was substantial increase in concentration of heavy metals ingoing from the water to the ...

Some haematological variables including Red Blood Cells (RBC), White Blood Cells (WBC) differential counts, Haemoglobin (Hb), Haematorite (HCT), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were measured in 90 stellate sturgeon juveniles Acipenser stellatus (1-2 years old) and 90 Persian sturgeons Acipenser persicus (1-2...

This study was carried out to find any relative concentrations of the trace metals (Cu, Cd, Zn and Pb) in the liver and the kidney of Acipenser persicus and in the surficial sediments of the west coast of The Southern Caspian Sea. Twenty five samples of the Acipenser persicus (Persian sturgeon) and ten samples of the sediments were taken from five fishing stations in autumn 2001. The tissues we...

Abstract The eastern part of the Black Sea and its tributaries are suitable habitats for several sturgeon species, among which Acipenser gueldenstaedtii , A. stellatus nudiventris persicus sturio H. huso well documented. However, different threats have led these species to a dramatic decline, all them currently listed as Critically Endangered some Locally Extinct in that area. We tested 94 wild...
