There is little experimental data on growth, production, feeding and ecosystem effects of C. pengoi. Both waterfleas entered the Great Lakes in ship ballast water from Europe – the spiny waterflea arrived in the 1980’s, followed in the 1990’s by the fishhook water flea. Reproduction of the cercopagids (Cladocera, Polyphemidae) in the Caspian Sea. C. pengoi interferes with fisheries by clogging nets and fishing gears. It is believed to have arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. Põllumäe A; Kotta J, 2007.

Fishhook Water Flea Distribution The species is from Eurasia. Spiny water fleas eat zooplankton that are an important food for native fishes. Both in the Caspian Sea (Rivier, 1998) and Lake Ontario (Ojaveer et al. They have a single long tail with one to four spines and have one large, distinctive black eyespot. C. pengoi is greyish white and almost transparent. Absence of data does not necessarily mean absence of the species at that site, but that it has not been reported there. The “resting eggs” of this water flea can be transported long distances, and can even survive cold winters on the sea bed, hatching only when the water is warmer and food is available. The fishhook water-flea is hard to see because its body is clear to milky-white, but it does have a large black eye making it more visible, especially when individuals are clumped together in large groups. The fishhook waterflea is a native of Eurasia. Fishhook water flea was first found in North America in 1998 in Lake Ontario; Characteristics. C. pengoi competes with a number of nectobenthic mysids and fish larvae for food (Kotta et al., 2004, 2006). During the summer when the water is warm, spiny water fleas reproduce rapidly, with each spiny water flea able to produce up to 10 new ones in just two weeks. Other major predators of Water Fleas are the Backswimmer, Water Boatman and the larvae of the Phantom Midge. Abstracts. It is believed to have arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. Canadian Journal of Fisheries and Aquatic Science, 56:1-5. Cercopagis is distinguished from Bythotrephes by the presence of the loop on the caudal process whereas Bythotrephes does not have such a loop. It arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. Eats phytoplankton. Fishhook waterfleas collect in gelatinous globs on fishing equipment and lines. They are unable to move upstream so they will not be introduced through the LaChute River. Species Profile: Spiny Water Flea. Gorokhova E; Hansson S; Höglander H; Andersen CM, 2005.

Fishhook water flea. ICES Journal of Marine Science, 56:49-57. The Lake Champlain Research Institute confirmed that organisms collected off of fishing lines of boats exiting the lake this week were fishhook waterfleas and a small number of spiny waterfleas. It arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. It belongs to the same family as Bythotrephes (Cercopagididae), and, like Bythotrephes, has a long caudal process (“tail”) with up to three pairs of barbs near its end. Parthenogenic females of the first generation of C. pengoi that hatch from resting eggs are anatomically distinct from parthenogenic females of following generations. Only about ¼ to ½ inches in length, individual waterfleas may go unnoticed.

In addition, the spiny water flea has a dark black eye that can easily be seen against its contrasting light body. Reasons for success. Range expansion of the exotic zooplankter Cercopagis pengoi (Ostroumov, 1891) into western Lake Erie and Muskegon Lake.

Resting eggs are also resistant to desiccation, freeze-drying and ingestion by predators (such as other fish). Invasion of Lake Ontario by the Ponto-Caspian predatory cladoceran Cercopagis pengoi. However, there is no evidence of diurnal migrations of C. pengoi in the Baltic Sea (Krylov et al., 1999). Introductions occur either due the construction of canals between river water basins (mainly those in Russia and the Ukraine), ballast water discharge (Baltic Sea and the Great Lakes) or boat traffic (within the region of the Great Lakes). Limnology and Oceanography, 47:626-635. Control and Management Problems for Anglers: Cercopagis can achieve very high population densities in lakes dur- ing the summer. In: Guides to the identification of the micro-invertebrates of the continental waters of the world [ed. However, population densities of the fishhook water flea increase with distance from shore (IUCN 2010), suggesting that this species may be able to occupy the entire region, including the deeper waters of Lake Superior, given sufficient time (USEPA 2008).” 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing Effects of the non-indigenous cladoceran Cercopagis pengoi on the lower food web of Lake Ontario.

They can spread to inland waters when fishing gear is contaminated with egg-laden females. Lake Superior. It likely arrived in Lake Champlain by hitchhiking overland on recreational boats, trailers, fishing lines, and other equipment. Its most probable route of introduction to the Great Lakes was via the ballast water of ocean cross- ing ships. C. pengoi is native to the Ponto-Aralo-Caspian Basin. Eggs produced in the early part of the season are delicate and very susceptible to damage, with low recruitment rates. ICES, 2005.
