biomarkers are assigned as early warning systems regarding aquatic organisms exposed to pollutants. among which, however, measurement of esterase enzymes activity specially cholinesterase of fish tissues, is a marker for exposure to organophosphate pesticide and carbamates, and this biomarker has been used widely in broad range of investigations. a number of capoeta capoeta gracilis (:cyprinida...

Cobalt, which is commonly used in many fields, may present an environmental risk. In this study, effects of cobalt parahydroxybenzoate (CoPHB), a less known form of cobalt, on tissue histopathology and serum proteins of Capoeta capoeta capoeta were investigated. Fish obtained from Kars River, Turkey were placed for 10 days in 500 L-containers in which CoPHB was added at 1 or 2 mg/L of final con...

The concentrations of heavy metals (Ag, Cd, Co, Cu, Ni, Pb, Zn) were analyzed in muscle, skin and liver of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Çamlıgöze Dam Lake located at Central Anatolian region of Turkey. The heavy metal analysis of samples was carried out by using a flame atomic absorption spectrophotometer. Ag, Cd, Co, Pb and Zn were found in all of the examined tissues...
