Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Asexual Sexual References: Simm M, Ojaveer H (1999) Occurrence of different morphological forms of Cercopagis in the Baltic Sea. Proceedings of the Estonian Academy of Sciences Biology Ecology, 48:169-170. MacIsaac, H. J., Grigorovich, I. A., Hoyle, J. A., Yan, N. D., & Panov, V. E. (1999). Invasion of Lake Ontario by the Ponto–Caspian predatory cladoceran Cercopagis pengoi. Canadian Journal of Fisheries and Aquatic Sciences, 56(1), 1-5. Comments: C. pengoi generally reproduce asexually throughout most of the summer season. Parthenogenic females of the first generation of C. pengoi that hatch from resting eggs are anatomically distinct from parthenogenic females of following generations. It occasionally reproduces sexually |
Developmental trait (?) | Brooding Resting stages References: Simm M, Ojaveer H (1999) Occurrence of different morphological forms of Cercopagis in the Baltic Sea. Proceedings of the Estonian Academy of Sciences Biology Ecology, 48:169-170. Comments: In addition, the “resting eggs” of this water flea can be transported over long distances, and can even survive cold winters on the sea bed. |

References (not structured): Mordukhai-Boltovskoi FD, Rivier IK(1987)Khishchnye Vetvistousye (Podonidae, Polyphemidae, Cercopagidae i Leptodoridae) Fauny Mira. Nauka, Leningrad. Comments: C. pengoi is a predatory cladoceran. The diet includes mainly small crustaceans, both micro- and meso-zooplankton |

Habitat modifying ability potential (?) | Autogenic ecosystem engineers Comments: Biofouling of fishing equipment and nets |
Toxicity / Life stage (?) | Not relevant Comments: Fishermen have complained of allergic reactions after removing C. pengoi from their nets. Might be poisonous. |

Losses in the Primorsky Ribak fishery farm, at the northern shore of the lower Neva estuary, averaged a minimum of USD 50,000 in 1996–1998 and were caused by the fouling of fishing equipment by this cladoceran (Leppäkoski and Olenin, 2000, and references within). |
