Bucephaloides gracilescens is a common parasite in the intestine of the angler fish Lophius piscatorius, and the metacercariae have been recorded from a number of gadoid intermediate hosts. In a toxicokinetic study of lindane (g-hexachlorocyclohexane) in bullrout Myoxocephalus scorpius, metacercariae of B. gracilescens were found in the central nervous system (CNS). Furthermore, the metacercariae accumulated concentrations of lindane that were higher than in the surrounding CNS tissue. This is the first report of metacercariae of B. gracilescens in bullrout. In addition the present results contribute knowledge of the disposition of an important environmental contaminant in the metacercarial stage of a trematode that has been pointed out as a promising sentinel species of pollution in the marine environment.
