Invasive Species We Study: Sea Lamprey

Active
By Biological Threats and Invasive Species Research Program July 8, 2024

The parasitic sea lamprey invaded the Great Lakes in the mid-20th Century devastating valuable native fisheries and coastal economies. The USGS’ Upper Midwest Environmental Sciences Center and the Great Lakes Science Center’s Hammond Bay Biological Station, in collaboration with the Great Lakes Fishery Commission, have been and continue to lead research on sea lamprey control, providing the science to keep sea lamprey populations at bay.

Red Swamp Crayfish used in CO2 deterrent study.

Evaluation of dissolved carbon dioxide (CO2) as a non-physical deterrent to invasive Red Swamp Crayfish (Procambarus clarkii) and Rusty Crayfish (Faxonius rusticus)

Red swamp crayfish ( Procambarus clarkii) and Rusty crayfish ( Faxonius rusticus) are invasive crayfish species in nearly all Great Lakes states (https://nas.er.usgs.gov/viewer/omap.aspx?SpeciesID=217). Both species are a concern in Michigan because they can displace native crayfish populations, their feeding behavior reduces habitat for amphibians, juvenile fish, invertebrates, and waterfowl...

Sea lamprey (Petromyzon marinus) density estimates using environmental DNA surveillance

Sea lampreys are a species that invaded the Great Lakes presumably following the improvements made to the Welland Canal in 1920. First reported in Lake Erie in 1921, sea lampreys subsequently spread rapidly to the upper Great Lakes and had an established spawning population in all of the upper Great Lakes by 1947 (Applegate 1950). Following their introduction, sea lamprey devastated the commercial...

Survival and metamorphosis of Sea Lamprey in Lake Erie tributaries

Adult sea lamprey abundance in Lake Erie increased during the past decade, exceeding pre-control levels and causing extensive mortality on some strains of stocked lake trout (Markham 2015). Control agents speculate that this increase may be due to an uncontrolled larval sea lamprey population in the St. Clair River because other known sources of larval sea lampreys are regularly treated with...

This study continues our investigations into the effects of lampricides on mussels by extending research into potential effects on behavioral and reproductive endpoints on the plain pocketbook mussel(Lampsilis cardium).

Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with of 4-Nitro-3-(trifluoromethyl)phenol (TFM, a lampricide) is essential to reducing the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries.

Operation of an electrical barrier to block sea lamprey in the Black Mallard, Michigan, detailing stream temperature, conductivity, discharge, electric field intensity, and animals trapped and killed during 2016, 2017, and 2018 Operation of an electrical barrier to block sea lamprey in the Black Mallard, Michigan, detailing stream temperature, conductivity, discharge, electric field intensity, and animals trapped and killed during 2016, 2017, and 2018

Sea lamprey (Petromyzon marinus) control is achieved in tributaries to the Laurentian Great Lakes by applying lamprey-specific pesticides (lampricide) to habitats containing larval sea lamprey. Lampricide treatments are cheaper and more effective in watersheds where dams block runs of adult sea lamprey and hence limit the distribution of sea lamprey larvae. However, dams impound water...

Pedigree analysis and estimates of effective breeding size characterize sea lamprey reproductive biology Pedigree analysis and estimates of effective breeding size characterize sea lamprey reproductive biology

The sea lamprey (Petromyzon marinus) is an invasive species in the Great Lakes and the focus of a large control and assessment program. Current assessment methods provide information on the census size of spawning adult sea lamprey in a small number of streams, but information characterizing reproductive success of spawning adults is rarely available. We used RAD-capture sequencing to...

Estimation of lake-scale stock-recruitment models for Great Lakes sea lampreys Estimation of lake-scale stock-recruitment models for Great Lakes sea lampreys

Understanding recruitment dynamics is an essential part of effective fisheries management, whether the focus is on conservation, harvest policy development, or invasive species control. We developed a model that estimates lake-wide Ricker stock-recruitment relations for invasive sea lampreys (Petromyzon marinus) in each of the five Laurentian Great Lakes to inform future control efforts...

Two orthologues of the gene encoding the Na+-Cl− cotransporter (NCC), termed ncca and nccb, were found in the sea lamprey genome. No gene encoding the Na+-K+-2Cl− cotransporter 2 (nkcc2) was identified. In a phylogenetic comparison among other vertebrate NCC and NKCC sequences, the sea lamprey NCCs occupied basal positions within the NCC clades. In freshwater, ncca mRNA was found only in...
