dc.description.abstract | This study examines the responses of antioxidant parameters in the white muscle of four freshwater fish species: Rutilus rutilus (roach), Blicca bjoerkna (white bream), Carassius gibelio (Prussian carp) and Perca fluviatilis (European perch) after exposure to a bloom of Aphanizomenon flos-aquae (Cyanobacteria) in the Gruza Reservoir in Serbia. The set of analyzed biomarkers included the activities of antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and biotransformation phase II enzyme glutathione-S-transferase (GST), and the concentrations of total glutathione (GSH) and sulfhydryl (-SH) groups that were measured before and during the bloom. Our results show that SOD activity in C. gibelio and P. fluviatilis, GSH-Px and GST activities in all four fish, GR activity in R. rutilus and C. gibelio and the -SH group concentration in P. fluviatilis markedly decreased during the bloom. The activity of CAT in all four fish and the concentration of GSH in B. bjoerkna and P. fluviatilis significantly increased. The observed changes in nonspecific antioxidant biomarkers in fish muscle (especially CAT, GSH-Px and GST activities) suggest that these parameters could be useful tools in environmental monitoring programs of the freshwater ecosystems where cyanobacterial blooms occur. | en |
