First Occurrence of Cercopagis pengoi in Lake Michigan

Temporal and spatial separation allow coexistence of predatory cladocerans: Leptodora kindtii, Bythotrephes longimanus and Cercopagis pengoi, in southeastern Lake Michigan

“…The initial years following the introduction of Bythotrephes, Leptodora densities declined substantially, thought to be a result of competition and predation by the newly invaded predator (Lehman, 1991;Branstrator, 1995). Cercopagis' invasion was originally discovered in two localized areas of Lake Michigan in 1999 (Charlebois et al, 2001), and by 2000, it was abundant at our study area in the southeastern part of the lake (Vanderploeg et al, 2002).…”

Measures of larval lake whitefish length and abundance as early predictors of year-class strength in Lake Michigan

“…Cercopagis pengoi, the fishhook water flea, was first recorded in Lake Michigan in 1999 (Charlebois et al 2001). Like Bythotrephes longimanus, its relative, this invasive predatory cladoceran from the Ponto-Caspian region feeds on zooplankton.…”

Invasion biology of Ponto-Caspian onychopod cladocerans (Crustacea: Cladocera: Onychopoda)

“…A recent genetic study by Cristescu et al (2001) demonstrated that the population of C. pengoi in the North American Great Lakes is most likely to have originated from the Baltic Sea source population, namely the Neva Estuary (eastern Gulf of Finland). From Lake Ontario, C. pengoi has spread in only a few years to Lake Michigan, western Lake Erie and some adjacent inland lakes (Charlebois et al, 2001;Therriault et al, 2002).…”
