| effect of intestinal tapeworm clestobothrium crassiceps on concentrations of toxic elements and selenium in european hake merluccius merluccius from the gulf of lion (northwestern mediterranean sea). | the capacity for heavy metal bioaccumulation by some fish parasites has been demonstrated, and their contribution to decreasing metal concentrations in tissues of parasitized fish has been hypothesized. the present study evaluated the effect of the cestode clestobothrium crassiceps on the accumulation of trace elements in 30 european hake, merluccius merluccius, in spain (half of them infested by c. crassiceps). tissue samples from all m. merluccius and specimens of c. crassiceps from the infect ... | 2015 | 26434500 |
