Assessing the impact of a recent predatory invader: The population dynamics, vertical distribution, and potential prey of Cercopagis pengoi in Lake Ontario. Baltic Sea Environment Proceedings. Fishhook water flea originated from the Caspian Sea in Eastern Europe and was discovered in Lake Ontario in August 1998. Olenin S; Leppäkoski E; Gollasch S; Gruszka P; Skora K; Hoppe K; Ojaveer H; Orlova M, 2002. The fishhook waterflea, Cercopagis pengoi, is a species of water flea native to the Ponto-Aralo-Caspian basin in South Eastern Europe at the meeting point of the Middle East, Europe, and Asia.This species is similar to Bythotrephes longimanus, and occurs in estuaries, lakes, marine habitats, water courses, and wetland areas. This puts them in direct competition with juvenile fish for food. It arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. Common Name fish-hook water flea Genus & Species Cercopagis pengoi Family Cercopagididae Order Cladocera Class Branchiopoda Diagnosis: The head is essentially composed of a large single eye, where the amount of black pigment makes less than one half of the diameter of the eye. It is not known, therefore, whether Cercopagis will ultimately be an energetic source or sink in the Great Lakes. Invasion of Lake Ontario by the Ponto-Caspian predatory cladoceran Cercopagis pengoi. Only about ¼ to ½ inches in length, individual waterfleas may go unnoticed. Journal of Great Lakes Research, 27:10-18. For a recent study of C. pengoi in the Gulf of Gdansk see Bielecka and Mudrak (2010). Gorokhova E; Hansson S; Höglander H; Andersen CM, 2005. The spiny and fishhook water fleas produce rapidly through parthenogenesis, commonly known as asexual reproduction, which means that no males are required and populations can explode in number. 91-102. They were first identified by Canadian scientists in 1998, and were reported via Internet by Dr. Hugh MacIsaac. 698-701. Cercopagis pengoi (Cladocera) conquered the southern Baltic Sea. New data on the non-indigenous cladoceran Cercopagis pengoi (Ostroumov 1891) in the Gulf of Gdansk (Baltic Sea). 95-96. Brood pouch and the egg development in Cladocera. 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. Canadian Journal of Fisheries and Aquatic Sciences, 59:1209-1228. Characteristics/species description The fishhook water flea is a predatory zooplankton. The invader is known as the fishhook water flea (Cercopagis pengoi). Cercopagis pengoi as a new prey item for alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax) in Lake Ontario. Spiny Waterfleas were the first to arrive via ballast water in the early eighties. The fishhook waterflea is a native of Eurasia. Common name: fishhook waterflea. What problems does it cause? Proceedings of the Estonian Academy of Sciences Biology Ecology, 51:91-102. Fact sheets on invasive alien species. Ojaveer H; Kuhns LA; Barbiero RP; Tuchman ML, 2001. Presence of the species results in economic losses at fish farms (intense clogging of nets). Bythotrephes, a water flea with a long, spiny tail, eats other zooplankton and competes with fish for food. The spiny water flea is similar to another introduced Cladoceran of the same family, the fishhook water flea Cercopagis pengoi, which, however, has a more slender spine featuring a prominent loop-like hook at its end (see figure). North European and Baltic Network on Invasive Alien Species, unpaginated. The fishhook water flea, an invasive crustacean named for its barbed spine, was first spotted in Lake Champlain in 2018. Reasons for success. Eats phytoplankton. 429 (1/3), 207-218. It is possible that the high population densities of the species will create significant predation pressure on smaller cladocerans to impact the size and composition of native phytoplankton communities. Range expansion of the exotic zooplankter Cercopagis pengoi (Ostroumov, 1891) into western Lake Erie and Muskegon Lake. The species tolerates a broad range of salinity, temperature and eutrophication conditions and is highly invasive. Distribution, fecundity, and genetics of Cercopagis pengoi (Ostroumov) (Crustacea, Cladocera) in Lake Ontario. The fishhook water flea was first found in the United States in 1998 in Lake Erie and Lake Ontario. They are unable to move upstream so they will not be introduced through the LaChute River. Clean all gear and equipment with either hot water (140°F/60°C), or salt water, OR let boats and equipment dry thoroughly for at least five days before entering a new water body. It is believed to have arrived in the Great Lakes in ballast water in the 1980s and spread to other water bodies. Fishhook water flea was first found in North America in 1998 in Lake Ontario; Characteristics. C. pengoi interferes with fisheries by clogging nets and fishing gears. Body: The spiny water flea has a 1/4"-1/2" long, translucent body, making it hard to spot unless gathered in a large cluster. Some results of the observations on the crustacean and rotifer plankton of the Neva Bay and the Gulf of Finland. Fishhook Waterflea Select Another Location: Total Locations: 1 Total Lakes and Rivers: 1 * Disclaimer: Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. Distribution of the non-indigenous Cercopagis pengoi in the coastal waters of the eastern Gulf of Finland. They have a single long tail with one to four spines and have one large, distinctive black eyespot. This species has also been found in Grand Traverse Bay and southern Lake Michigan and in western Lake Erie and the Detroit River. Krylov PI; Bychenkov DE; Panov VE; Rodionova NV; Telesh IV, 1999. An invasion history for Cercopagis pengoi based on mitochondrial gene sequences. Trick or Treat Food Web The fishhook water flea's position in the food web is nothing since it has no predators. Spiny and fishhook waterfleas are small aquatic predators native to Eurasia. The fishhook waterflea has a slender spine and prominent S-shaped loop on the tail. The fishhook water flea is known to make up a portion of the adult alewife diet in Lakes Ontario, Erie, and Michigan, but this contribution does not appear significant relative to Bythotrephes longimanus, another nonindigenous spined cladoceran, when these species co-occur (Pothoven et al. ICES Journal of Marine Science. Noxious Weed: Priority 2A Aquatic Invasive Species Non-native Species. Rivier IK, 1998. Põllumäe A; Kotta J, 2007. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. To differentiate these two water fleas apart compare their body sizes and the terminal shape of their tail spines. The contribution of nonindigenous Cercopagis pengoi (Ostroumov) in the mesozooplankton community and its population structure in the Gulf of Riga. In these inland lakes, Cercopagis now dominates the offshore zooplankton community during the summer and fall. Ecological consequences of biological invasions: three invertebrate case studies in the north-eastern Baltic Sea. What problems does it cause? 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. Fishhook Water Flea Cercopagis pengoi How it was introduced it Ontario? In these new habitats the species has established quickly and increased in range and abundance. Wallingford, UK: CABI, CABI, Undated a. CABI Compendium: Status as determined by CABI editor.

All introductions are accidental. Kotta J; Simm M; Kotta I; Kano?ina I; Kallaste K; Raid T, 2004. 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 Dispersal and emerging ecological impacts of Ponto-Caspian species in the Laurentian Great Lakes. http://el.erdc.usace.army.mil/ansrp/cercopagis_pengoi. The species is also characterized by a long spine that extends from its abdomen, giving the reason for its name. Crosier DM; Molloy DP, 2007. When several references are cited, they may give conflicting information on the status. It is a member of a large group of organisms called crustaceans and is a relative of the invasive species, the spiny In: Guides to the identification of the micro-invertebrates of the continental waters of the world [ed. 2001) the abundance of C. pengoi increases with distance from shore suggesting that this is a typical pelagic species. There is little experimental data on growth, production, feeding and ecosystem effects of C. pengoi. It likely arrived in Lake Champlain by hitchhiking overland on recreational boats, trailers, fishing lines, and other equipment. Since its first discovery in Lake Ontario in August 1998, copagis spread inland to six of New York’s Finger Lakes (Seneca, Cayuga, Otisco, Canandaigua, Owasco and Keuka) within a year, possibly on fishery sampling gear, in bait buckets, or on recreational angling equipment.
