Introduction and establishment of the pikeperch Stizostedion lucioperca (L.) in Stanborough Lake (Hertfordshire) and its dispersal in the Thames catchment.

By G.H. Copp, K. Wesley, M. Ives and M.G. Carter.

European pikeperch (or zander) Stizostedion lucioperca (L.) were illegally introduced into Stanborough Lake (Hertfordshire, England) in 1985. We examined fisheries survey data, anglers’ reports and Environment Agency records to summarize the events surrounding the species’ introduction, its spread into the adjacent River Lee and down the river into the River Thames catchment. We also studied the species’ environmental biology (morphology, growth, reproduction) and establishment success in the lake. Our results are examined in light of available data from the UK and Continental Europe, and implications of the species’ invasion are discussed.
