Abstract: Bioaccumulations of Zn and Cuin liver and intestinal tissue of the fish Chasar bathybius (Gobiidae) and its nematode parasite Dichelyne minutus (Rudolphi, 1819) were studied and compared. Concentrations of Zn and Cu were measured using Inductively Coupled Plasma (ICP-OES). Concentrations of Zn and Cu in Dichelyne minutus were markedly higher than in the liver and intestinal tissues of the specimens. Zn concentration in the fish liver increased with an increased density of the parasite. Bioconcentration Factor for intestinal tissue (BF=C parasite /C host intestine) reached to 42-194 for Cu and 25-65 for Zn. BF in the liver tissue ranged from 19 to 88 for Cu and 48 to 96 for Zn. Nematode parasites may have a beneficial influence on the health of the host fish and enable the survival of their hosts from heavy metal absorption.
