dc.description.abstractDuring the early growth season of 1999 to 2001, Cercopagis abundance in offshore waters of Lake Ontario remained low (less than 30 individuals/m3). From late July, its abundance increased rapidly until it peaked during August. After first appearing in 1998, maximum offshore abundance in Lake Ontario decreased each year since 1999 (1999:1759/m3; 2000: 679/m3; 2001: 355/m3). Cercopagis appears not to migrate below the thermocline and is restricted to the epilimnion. A comparison of pre- and post-invasion average abundance of Daphnia retrocurva, Bosmina longirostris and Diacyclops thomasi suggests that Cercopagis is having a major effect on zooplankton composition and abundance in Lake Ontario. Abundance of all three species has decreased significantly in the offshore waters since the invasion of Cercopagis. Preliminary results also suggest that insertion of Cercopagis pengoi into the Lake Ontario food web will not elevate levels of hydrophobic organic compounds in salmonids through biomagnification.
