Tributyltin and copper effects on encystment and in vitro excystment of Parorchis acanthus larvae
Abstract Effects of tributyltin (TBT) and copper (Cu) on cercariae and metacercariae of the trematode Parorchis acanthus (Digenea: Philophthalmidae) were investigated. Cercariae released by the dogwhelk, Nucella lapillus were maintained in natural seawater (SW) or solutions of TBT or Cu ranging from...
