Description 196-200
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.
