The impact of environmental stress on chub (Leuciscus cephalus) and their parasites
Original language description
he main aim of this study was to monitor effects of aquatic pollution on parasites and their hosts and to find reliable indicators of environmental stress. As a model host was chosen freshwater fish chub (Leuciscus cephalus (L.)), collected at two modelsites with different level of pollution in Vlára and Bílina Rivers (Czech Republic). Polycyclic aromatic hydrocarbons (PAH) appeared to be predominant organic pollutants at both sites, and their levels were elevated particularly in Bilina River. By contrast, the concentrations of polychlorinated biphenyls (PCB) were very low at both sites. Concentrations of PAH metabolite 1-hydroxynapthol (1-OH-Nap) in fish bile, PCB congeners and heavy metals in fish muscle were measured. EROD activity was used as a specific biomarker of dioxin like compounds (PAH, PCB, dioxins).
