Abstract:

In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were  investigated using  several  biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepatosomatic index, condition factor and lipid peroxidation (LPO) level and also the activities of superoxide dismutase  (SOD) and catalase (CAT) were measured. These results indicated that  there was significant lower condition factor in fish exposed to the highest concentration of Pb (p

Biochemical changes of antioxidant enzymes in common carp (Cyprinus carpio L.) after heavy metal exposure

Accidental industrial spills may lead to a high concentration of toxic metals in the aquatic environment, as well as affecting freshwater ecosystems with acute and chronic toxicity. Of all aquatic species, fish are particularly sensitive to waterborne contamination and are recognized as bioindicators for water quality monitoring. The objective of the present study was to evaluate the biochemica...

Histological and biochemical changes in liver of common carp (Cyprinus carpio L.) under metal exposure

In the present study our major aim was to evaluate the up-to-date contamination status of the Topolnitsa reservoir. It is located in a region with intensive copper mining, which has been constantly contaminated with metals in the last few decades. Thus, we measured As, Cd, Cu, Ni, Pb, and Zn concentrations in surface water samples, as well as, in liver of сommon carp in three different seasons ...

Common Carp, Cyprinus carpio

The common carp (Cyprinus carpio) belongs to the family Cyprinidae. In nature, carp live in the middle or lower reaches of a river with slow currents, or in marshes. Their habitats are usually weedy areas with a muddy bottom. Carp fry feed on zooplankton such as rotifers and copepods, but as they grow up they become benthic feeders, feeding on animals and other organic material. The cyprinids h...

Common carp - Cyprinus carpio

Distribution ! e common carp [Cyprinus carpio Linnaeus (1758)] has been one of the oldest domesticated species of fi sh for food. Culture of carp in China dates back to at least the 5th century BC, although domestication began much later. ! e European races of carp derived from wild carp of the Danube; the earliest attempts date back to the Roman Empire and spread of Christianity in Europe, fro...

Recovery ability of common carp (Cyprinus carpio) after a short-term exposure to terbuthylazine.

Effects of a high terbuthylazine concentration (3.3 mg/1) on Cyprinus carpio were studied using a commercial herbicide formulation Click 500 SC (terbuthylazine 500 g/l). The fish were exposed to the pesticide for 24 h and allowed to recover for 6 days. Biometric parameters, plasma biochemical parameters and biomarkers of oxidative stress as well as histopathological changes in selected tissues ...

Blood biochemical changes in common carp (Cyprinus carpio) upon co-exposure to titanium dioxide nanoparticles and paraquat

Research on eliminating organic pollutants in water by using heterogeneous photocatalysts such as nano-TiO2 abound. However, the question is whether metabolites, resulting from optical dispersion of environmental pollutants, are still toxic to aquatic organisms. Therefore, this study was designed to evaluate the effect of a co-exposure to paraquat and TiO2-NPs on blood biochemical indices of co...
