Sea lamprey (Petromyzon marinus) control with selective toxicants has reduced sea lamprey abundance in the Great Lakes to levels which permit survival of desirable fish species, but development of alternate and supplemental control methods is essential since chemicals cannot be used indefinitely. The Task Force addressed hypotheses which relate to regulation of sea lamprey numbers during different life history stages and why sea lampreys appear to affect fish stocks differently in various bodies of water. Examination of the information about the various factors that control sea lamprey abundance, both natural and man-made, permitted the Task Force to develop several hypotheses and to indicate areas where additional emphasis or research could produce new or supplementary control methods. Efforts to develop an integrated program of sea lamprey control should be accelerated by development of present promising areas as well as expansion in new directions. Sea lampreys when compared with teleosts exhibit many features of a prototype vertebrate and some unique specializations. Physiological, biochemical, or behavioral differences between lampreys and teleosts may be exploitable for developing control techniques specific to sea lampreys.Key words: sea lamprey, Great Lakes, population control, barrier dams, integrated pest management, buffer species, physiology, teleosts

St Lawrence River

Sea lamprey (Petromyzon marinus) are established in each of the several discrete areas in the St. Lawrence River system between Lake Huron and the Moses–Saunders Power Dam (160 km below Lake Ontario) except for the Niagara River between Niagara Falls and Lake Ontario. However, chemical lampricide treatments are being used to control these populations only in Lake Ontario. Experimental introductions of trout and salmon in Lake Ontario between 1968 and 1971 were not successful. Survival was limited and the number of sea lamprey attack marks on the fish that did mature was very high. After the first round of lampricide treatments of most sea lamprey producing tributaries in 1972, survival of fish improved and lamprey attacks declined. Studies are being completed to determine the desirability of including Oneida Lake in the treatment schedule to prevent recruitment of sea lampreys from this area to Lake Ontario and to improve the fish populations of Oneida Lake. Treatment of Lake Champlain also is being studied by management agencies concerned with its fisheries. Lake St. Clair and Lake Erie and connecting waters, the Finger Lakes, and the St. Lawrence River below Lake Ontario do not appear to have sea lampreys in the numbers necessary to cause unacceptable levels of predation on fish populations and are not being considered for inclusion in the Great Lakes Fishery Commission control program at this time.Key words: sea lamprey, predation, abundance, history, Erie, Ontario, Oneida, Finger Lakes, Champlain

Sea Lampreys

Criteria for the classification of marks inflicted by sea lamprey (Petromyzon marinus) into nine categories were developed from laboratory studies in an attempt to refine the classification system used in field assessment work. These criteria were based on characteristics of the attachment site that could be identified under field conditions by unaided visual means and by touching the attachment site. Healing of these marks was somewhat variable and was influenced by the size of lamprey, duration of attachment, severity of the wound at lamprey detachment, season and water temperature, and by other less obvious factors. Even under laboratory conditions staging of some wounds was difficult, especially at low water temperatures. If these criteria are to be used effectively and with precision in the field, close examination of individual fish may be required. If the feeding and density of specific year-classes of sea lampreys are to be accurately assessed on an annual basis, close attention to the wound size (as it reflects the size of the lamprey's oral disc) and character of wounds on fish will be required as well as consideration of the season of the year in which they are observed.Key words: sea lamprey, attack marks, lake trout, Great Lakes

Novel Strategy

Stream-finding behavior of adult sea lamprey ( Petromyzon marinus ), an anadromous fish that relies on pheromones to locate spawning streams, was documented in the vicinity of an important spawning river in the Great Lakes. Untreated and anosmic migrating sea lampreys were implanted with acoustic transmitters and then released outside the Ocqueoc River. Lampreys swam only at night and then actively. When outside of the river plume, lampreys pursued relatively straight bearings parallel to the shoreline while making frequent vertical excursions. In contrast, when within the plume, lampreys made large turns and exhibited a weak bias towards the river mouth, which one-third of them entered. The behavior of anosmic lampreys resembled that of untreated lampreys outside of the plume, except they pursued a more northerly compass bearing. To locate streams, sea lampreys appear to employ a three-phase odor-mediated strategy that involves an initial search along shorelines while casting vertically, followed by river-water-induced turning that brings them close to the river’s mouth, which they then enter using rheotaxis. This novel strategy differs from that of salmonids and appears to offer this poor swimmer adaptive flexibility and suggests ways that pheromonal odors might be used to manage this invasive species.

Laurentian Great Lakes fishery management agencies are seeking ways to identify natal origins of parasitic- and spawning-phase sea lamprey ( Petromyzon marinus ) so that efforts to control this invasive species can be prioritized. We developed laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) as a technique to quantify elemental concentrations in larval sea lamprey statoliths and explored the use of statolith microchemistry as a tool to discriminate among larval sea lamprey production streams. Our analyses demonstrate that (i) traversing across the statolith with the laser is preferable to drilling down through its apex, (ii) preserving specimens in 95% ethanol versus freezing them has minimal effects on elemental concentrations, (iii) a minimum of 15 individuals per stream should accurately depict stream-specific statolith elemental signatures, and (iv) LA-ICP-MS is preferable to particle-induced X-ray emission (PIXE) for statolith analysis, based on higher precision, lower cost, reduced sampling-time requirements, and wider availability. Using LA-ICP-MS, we could discriminate among larvae from 13 streams located in Lakes Michigan, Huron, and Superior with 82% classification accuracy, indicating that this tool holds promise for determining natal origins of sea lamprey in the Great Lakes.

The chemicals 3-trifluoromethyl-4-nitrophenol (TFM) or a combination of TFM and 2′,5-dichloro-4′-nitrosalicylanilide (Bayer 73) have been used to control the sea lamprey (Petromyzon marinus) in the Great Lakes for about 20 yr. These chemicals cause some mortalities of Oligochaeta and Hirudinea, immature forms of Ephemeroptera (Hexagenia sp.), and certain Trichoptera, Simuliidae, and Amphibia (Necturus sp.). The combination of TFM and Bayer 73 may affect some Pelecypoda and Gastropoda, but its overall effects on invertebrates are probably less than those of TFM alone. Granular Bayer 73 is likely to induce mortalities among oligochaetes, microcrustaceans, chironomids, and pelecypods. No evidence exists that the lampricides have caused the catastrophic decline or disappearance of any species. The overall impact of chemical control of sea lampreys on aquatic communities has been minor compared with the benefits derived.Key words: sea lamprey control, Great Lakes, TFM, Bayer 73, aquatic plants, invertebrates, amphibians

Sea Lampreys

Here we confirm a long-standing anecdotal observation; the sea lamprey ( Petromyzon marinus ) actively avoids the odor emitted by decaying conspecifics. We extracted the semiochemical mixture produced by the putrefying carcasses of sea lampreys via Soxhlet extraction in ethanol and exposed groups of 10 migratory-phase lampreys to either the putrefaction extract (N = 8) or an ethanol control (N = 8) in a laboratory raceway. Sea lampreys rapidly avoided the putrefaction odor while exhibiting no response to the ethanol control. This response was elicited with a diluted mixture (1:373 000) and was maintained for 40 min (the duration of exposure), after which the lampreys quickly returned to their nominal distribution. The ease with which this odor is obtained, and the rapid and consistent behavioral response, suggests the substance will prove useful as a repellent in the sea lamprey control program carried out in the Laurentian Great Lakes.

Sea lamprey (Petromyzon marinus) ammocoetes of known age were confined in three locations to determine the effects of temperature on the incidence of metamorphosis. Sixty ammocoetes were held in each of Lake Superior, the Big Garlic River, and in an aquarium at room temperature for each of 4 yr. The highest incidence of metamorphosis (75–100%) occurred at 20–21 °C (aquarium), an intermediate rate (46–76%) at 14–16 °C (Big Garlic River), and the lowest (5–10%) at 7–11 °C (Lake Superior). Density appeared to be the dominant factor in regulating the length of larval and transformed sea lampreys. Mean lengths of larval and transformed sea lampreys increased markedly after stream treatments with selective lampricides. Prediction of lengths at which metamorphosis occurs in re-established populations of sea lampreys is uncertain because of variability in growth rates. Initial metamorphosis in a year-class is dependent on growth rates of ammocoetes. Because of wide variation in growth rates, metamorphosis may begin at age III among fast-growing populations and not until age VII among slow-growing populations.Key words: Petromyzon marinus, sea lamprey; metamorphosis, age, length, Great Lakes

Seven hundred and fifteen adult sea lampreys (Petromyzon marinus von Linné) from four streams tributary to Lake Huron and five offshore samples from the Manitoulin Island – Bruce Peninsula area, were examined for parasites.Dissection and microscopic examination revealed the presence of eight parasite species. Cucullanus stelmioides Vessichelli, 1910 is recorded for the first time both as a parasite of P. marinus and from North American waters. Ergasilus caeruleus Wilson, 1911, Anodontoides ferussacianus Lea. 1834, Diplostomum huronense (La Rue 1927), Plagioporus lepomis Dobrovolny, 1939 are all recorded for the first time as parasites of P. marinus. Echinorhynchus salmonis Müller, 1784, Triaenophorus crassus Forel, 1868, and Proteocephalus sp. are redescribed as parasites of the sea lamprey.

Spawning Run

During lampricide treatment of a stream, sea lamprey, Petromyzon marinus, that will constitute the spawning run the following spring inhabit the Great Lakes and are not affected by the treatment. However, the number of adults captured at electrical barriers declined as much as 99% in some streams 1 year after chemical treatment. Large declines of adults were noted in streams which were treated late in the year. Streams in which significant populations of larval lampreys survived the chemical treatment, or contained lentic populations, continued to attract adults. Adult sea lampreys could be attracted to sea lamprey ammocoetes in streams or in offshore areas and hence use this as one of a number of clues to determine rivers suitable for spawning.Key words: sea lamprey, olfaction, orientation/homing, spawning migration, habitat alteration (chemical), Petromyzon marinus, lampricides
