Petromyzon marinus   Linnaeus 1758

Common Name: sea lamprey

Taxonomy: available through ITIS logo

Identification: Becker (1983); Page and Burr (1991); Jenkins and Burkhead (1994); Vladykov and Kott (1980) provided a key to the ammocoetes of lampreys found in the Great Lakes region. Eel-like in appearance, but not an eel. Sea lamprey is a cartilaginous fish without jaws. This species has two close dorsal fins, no paired fins, seven gill openings, and a large round mouth with sharp, curved teeth. (Page and Burr 1991; Jenkins and Burkhead 1994).

Size: 120 cm anadromous; 64 cm landlocked.

Native Range: Generally marine but ascends freshwater rivers to spawn. Atlantic Coast from Labrador to Gulf of Mexico, Florida; landlocked in Great Lakes and several New York lakes. Also along Atlantic coast of Europe and Mediterranean Sea (Page and Burr 1991).

Nonindigenous Occurrences: Lampreys were first discovered in Lake Ontario in 1835, Lake Erie in 1921, Lake Michigan in 1936, Lake Huron in 1937, and Lake Superior in 1946 (Applegate 1950; Lawrie 1970; Smith 1979; Smith and Tibbles 1980; Smith 1985). Its distribution in all five Great Lakes and selected tributaries includes the states Illinois (Smith 1979; Emery 1985); Indiana (Gerking 1955; Emery 1985); Michigan (Applegate 1950; Smith 1979; Cudmore-Vokey and Crossman 2000); Minnesota (Eddy and Underhill 1974; Phillips et al. 1982; Emery 1985); New York (Smith 1985); Ohio (Trautman 1981; Emery 1985; USFWS 2005); Pennsylvania (Emery 1985); and Wisconsin (Becker 1983; Emery 1985). This species is also present in Apostle Islands National Lakeshore, Wisconsin; Indiana Dunes National Lakeshore, Indiana; Isle Royale National Park, Pictured Rocks National Lakeshore, and Sleeping Bear Dunes National Lakeshore, Michigan (Tilmant 1999); and Walnut Creek, Pennsylvania (Phillips et al. 2003).

This species was formerly believed to be introduced into the Finger Lakes and Lake Champlain in  New York and Vermont (Lee et al. 1980 et seq.).  However recent genetic evidence shows it is native to these areas (Bryan et al. 2005).

Means of Introduction: Controversy exists as to whether the sea lamprey is native to Lake Ontario. Several believe it is native (e.g., Lawrie 1970; Smith 1985), suggesting that sea lampreys found in Lake Ontario and its tributaries, the Finger Lakes, and Lake Champlain represent relict populations from the last Pleistocene glaciation. Those contending that it is not native believe that this species, unknown in Lake Ontario prior to the 1830s, had most likely entered the inland lake from Atlantic coastal drainages via the artificially created Erie Canal (e.g., Emery 1985). Whether or not the sea lamprey is native to Lake Ontario, this species is not native to the other Great Lakes and tributaries where it is now readily found. The sea lamprey was previously prevented from spreading into Lake Erie and the rest of the Great Lakes basin by Niagara Falls. The Welland Canal, opened in 1829, bypassed Niagara Falls providing a route to Lake Erie from Lake Ontario (Aron and Smith 1971). From the opening of the Welland Canal (1829) to the discovery of sea lamprey in Lake Erie (1921), there is almost a century difference. Yet sea lampreys were found throughout the Great Lakes to the farthest Great Lake, Lake Superior, within twenty-five years of their arrival to Lake Erie. The improvements done to the Welland Canal in 1919 are likely the change that facilitated sea lamprey immigration into Lake Erie (1921) (Great Lakes Fishery Commission, on-line resource). 

Status: Established throughout the Great Lakes region. This species was common in lakes Michigan and Huron by the 1930s and in eastern Lake Superior by the 1940s; it never became very abundant in Lake Ontario (Applegate 1950; Emery 1985) or Lake Erie (Smith 1985).

Impact of Introduction: Attack and parasitic feeding on other fishes by adult lampreys often results in death of the prey, either directly from the loss of fluids and tissues or indirectly from secondary infection of the wound (Phillips et al. 1982). Of the fish that survived attacks by lampreys, 85% of various species had been attacked up to five times (Scott and Crossman 1973). The species' introduction to the Great Lakes and its later abundance, combined with water pollution and overfishing, resulted in the decline of several large native species, including several ciscoes Coregonus spp., lake trout Salvelinus namaycush, and walleye Stizostedion vitreum, among others. Consequently, there was a collapse in the commercial fisheries during the 1940s and 1950s in many parts of the Great Lakes, particularly in lakes Huron and Michigan, and in eastern Lake Superior (e.g., Lawrie 1970; Scott and Crossman 1973; Christie 1974; Lee et al. 1980 et seq.; Smith and Tibbles 1980; Becker 1983; Emery 1985; Courtenay 1993). Lake trout catch in Lake Huron fell from 3.4 million pounds in 1937 to virtual failure in 1947. In Lake Michigan, U.S. catch fell from 5.5 million pounds in 1946 to 402 pounds in 1953. In Lake Superior, catch dropped from an average of 4.5 million pounds to 368 thousand pounds in 1961 (Scott and Crossman 1973). In freshwater, sea lampreys are also known to attack white sucker Catostomus commersoni, longnose sucker Catostomus catostomus, redhorse Moxostoma spp., yellow perch Perca flavescens, rainbow trout Oncorhynchus mykiss, burbot Lota lota, channel catfish Ictalurus punctatus, northern pike Esox lucius, and common carp Cyprinus carpio (Scott and Crossman 1973). Sea lamprey predation, in combination with other factors (i.e., overfishing and hybridization with more common cisco species), led to the extinction of three endemics in the Great Lakes; the longjaw cisco Coregonus alpenae, the deepwater cisco C. johannae, and the blackfin cisco C. nigripinnis (Miller et al. 1989). During the late 1940s, the alewife Alosa pseudoharengus invaded the Great Lakes from the Atlantic Ocean. Because the sea lamprey had greatly reduced the population of large predators, alewife populations exploded and were followed by tremendous die-offs, resulting in additional changes to fish species composition in the lakes (Smith and Tibbles 1980). Sea lampreys also took a toll on the introduced salmon in the Great Lakes, much to the dismay of anglers and state fish agencies. Although the number of sea lamprey in the Great Lakes has been reduced, they still kill substantial numbers of lake trout in some areas and thus are impeding the rebuilding of established populations (Schneider et al. 1996, and references therein).

Remarks: Early methods to control this species included mechanical weirs and electrical barriers (Scott and Crossman 1973; Smith and Tibbles 1980). Beginning in the late 1950s, sea lampreys began to be successfully controlled by use of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM), a chemical agent that kills larval lampreys in their stream habitats (Smith and Tibbles 1980). The lampricide has reduced the population by over 90% of the 1961 peak (Scott and Crossman 1973). As a result, commercial fisheries reportedly have shown some recovery (Smith 1985; Page and Laird 1993) and the sea lamprey's impact on native fishes has been reduced (Page and Laird 1993). However, continued use of TFM is apparently required to keep sea lamprey populations under control (Scott and Crossman 1973; Becker 1983). TFM is sometimes harmful to other fish (e.g., walleye) (Becker 1983), as well as to the larvae of nonparasitic lamprey species.

Results of an international symposium on the sea lamprey were published in the Canadian Journal of Fisheries and Aquatic Sciences in 1980. The demise of lake trout led to development of the splake, a hybrid between lake trout and brook trout. It was hoped that the hybrid would better avoid lampreys and mature faster, hence spawn at least once before becoming parasitized (Scott and Crossman 1973).

As of 1991, it was estimated that the U.S. and Canada were spending $8 million per year on lamprey control and another $12 million per year on lake trout restoration (Newman 1991). The Sea Lamprey is one of the most important invasive species in the Great Lakes. Although perhaps the first invader to the Great Lakes, having migrated out of Lake Ontario in the 1830's and into the other Great Lakes through the Welland Canal, it was not until the 1950's that impacts on fisheries were so great as to prompt serious management efforts. It was then that the Great Lakes Fisheries Investigations, the progenitor of the present day USGS Great Lakes Science Center in Ann Arbor was charged with discovering a lampricide targeting the larval stage. The Great Lakes Fisheries Commission was also formed at this time, an organization primarily concerned with Sea Lamprey management. Successful application of lampricide ensued, reducing the Lamprey population dramatically.However, decimation by Sea Lamprey of predatory fish representing the top trophic levels of the Great Lakes food web had already caused another invader, the Alewife, to proliferate. The Alewife population exploded, causing fish kills that washed up on shore. Thus the Sea Lamprey created the need to control Alewife. Due also tothe decimation of native predatory fish populations by sea lamprey, a Great Lakes sport fishery was created with the stocking of Chinook Salmon in the 1960's.
