Abstrakt: The goal of this study was to determine the primary cause of reproductive disturbances in salmonids from the Tichá Orlice river. Three sites at the Tichá Orlice river were monitored during 2000-2003. Samples of fish muscle, bile and bottom sediment were collected on monitored sites for chemical analyses of PCB, HCB, DDT and its metabolites, HCH, OCS, 1 - OHPY (bile) and PAH (bottom sediment) concentrations. Vitellogenin (Vtg) concentration in brown trout (Salmo trutta fario) blood plasma was assessed using ELISA (Rainbow trout vitellogenin EIA kit). In comparison with the control site, locality at the source of pollution and on another locality downstream were found considerably polluted. This contamination was manifested also by repetitious findings of high Vtg concentrations in blood plasma, resulting in adverse effects on fish reproduction. [ABSTRACT FROM AUTHOR]
