• We assess larval and adult sea lamprey populations and control sea lamprey numbers with a variety of state of the art techniques. (msu.edu)
  • Manipulation of olfactory biology offers opportunities for management of populations in the Laurentian Great Lakes, where the sea lamprey is a destructive invader. (biomedcentral.com)
  • The largest European populations of sea lampreys are located throughout the southwestern areas of Europe (north-central Portugal, north-northwest of Spain, and west-southwest of France). (wikipedia.org)
  • The sea lamprey is a basal vertebrate with a complex life history comprised of distinct larval, juvenile, and adult stages. (biomedcentral.com)
  • Larval sea lamprey burrow into stream sediment and filter feed on organic material and microorganisms. (biomedcentral.com)
  • Following a larval stage of 3-5 years, sea lamprey undergo a drastic metamorphosis into the juvenile stage, migrate downstream into the Atlantic Ocean or a Laurentian Great Lake, and parasitize on large fish for approximately 1.5 years. (biomedcentral.com)
  • Olfaction is hypothesized to influence sea lamprey behavior throughout the larval, juvenile, and adult stages [ 9 - 11 ], but only during the terminal adult phase has the role of conspecific odors been evaluated. (biomedcentral.com)
  • Finally, adult sea lamprey migrate into streams during the spring, where a male will construct a nest and later be joined by one or more females, spawn intermittently for a number of days, and die [ 8 ]. (biomedcentral.com)
  • Schematic illustrating the hypothesized functions of migratory cues, alarm cues, and mating pheromones during reproduction in sea lamprey. (biomedcentral.com)
  • Sea lampreys parasitize other fishes for their diet, including elasmobranchs such as sharks and rays, which have naturally high levels of urea in their blood. (wikipedia.org)
  • After several years in freshwater habitats, the larvae undergo a metamorphosis that allows young, post-metamorphic lampreys to migrate to the sea or lakes, and start the adult hematophagous method of feeding. (wikipedia.org)
  • After one year of hematophagous feeding, lampreys return to the river to spawn and die, a year and a half after the completion of metamorphosis. (wikipedia.org)
  • PERM scientists have worked extensively with the commission's science program, particularly in the area of sea lamprey research, focusing on sea lamprey chemoreception, movement ecology and behavior, population dynamics, and assessment. (glfc.org)
  • Scientists at HBBS conduct research and provide technical support to the commission and its sea lamprey control agents: the U.S. Fish and Wildlife Service and Fisheries and Oceans Canada. (glfc.org)
  • Some individuals start hematophagous feeding in the river before migrating to the sea, where sea lampreys prey on a wide variety of fish. (wikipedia.org)
  • The lamprey uses its suction cup-like mouth to attach itself to the skin of a fish and rasps away tissue with its sharp, probing tongue and keratinized teeth. (wikipedia.org)
  • Lampreys are able to tolerate much higher concentrations than most other fish and excrete it at extremely high rates, obtained from ingested blood. (wikipedia.org)
  • Here, we provide a broad review of the chemical cues and pheromones used by the sea lamprey during reproduction, including overviews of the sea lamprey olfactory system, chemical cues and pheromones, and potential applications to population management. (biomedcentral.com)
  • Job Announcement # R3-17-10090659-KO-DE Opened 12/08/2017, closes 12/21/2017 The Marquette Biological Station delivers an integrated program of sea lamprey control in treaty with Canada to assist in restoration of the Great Lakes fishery. (msu.edu)
  • Sea Lamprey Research is important to the control program, including investigations into the sea lamprey's genome, pheromones and repellents, and development of innovative control techniques . (glfc.org)
  • The Science Transfer Program promotes uptake of science to fishery managers and sea lamprey control agents. (glfc.org)
  • Marquette is a community of about 25,000 people situated on the rugged shoreline of Lake Superior in the Upper Peninsula of Michigan. (msu.edu)
  • We suggest that the sea lamprey is a broadly useful organism with which to study vertebrate olfaction because of its simple but well-developed olfactory organ, the dominant role of olfaction in guiding behaviors during reproduction, and the direct implications for vertebrate pest management. (biomedcentral.com)
  • The critical role of olfaction in mediating the sea lamprey life cycle is evident by a well-developed olfactory system. (biomedcentral.com)
