Parasitic Phase

The sea lamprey (Petromyzon marinus) is widely distributed in the Great Lakes but it is absent from or scarce in large parts of the watershed. Since 1957, larval sea lampreys have been detected in only 433 (7.5%) of the 5747 streams in the Great Lakes basin. Parasitic-phase sea lampreys range throughout the lakes, wherever suitable host fishes occur, but probably do not inhabit the western and central basins of Lake Erie to any great extent during summer. Many environmental conditions influence the distribution of sea lampreys. Streamflow and water temperature are of major importance in attracting spawning runs to streams. The dispersal of spawning adults within streams is influenced mainly by blockages, water temperature, current, bottom type, and the presence of inland lakes. Water temperature is probably the most important factor affecting the development and survival of embryos. The distribution of larval lampreys is limited primarily by barriers that block adult spawning runs, warm temperatures, low and unstable flows, hard stream bottom, and pollution; nonetheless, larvae have been found in a wide range of habitats exhibiting these conditions. Interconnecting waterways and attachment to fishes and boats are considered major factors in the lake movements of parasitic-phase lampreys.Key words: sea lamprey, Petromyzon marinus; Great Lakes, geographic distribution, influences, movement, spawning, larvae, parasitic, control

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

Host Mortality

Groups of sea lampreys (Petromyzon marinus) of 10–90 g initial weight were held at temperatures of 1–20 °C for 30 days and allowed to feed ad lib. on white suckers (Catostomus commersoni). Increases in water temperature and in lamprey size caused the rate of host mortality to increase in agreement with observations that mortality in the Great Lakes is seasonal. Instantaneous growth rates were maximal at 20 °C for lampreys of 10–30 g, the optimal temperature for growth shifting to 15 °C for larger lampreys of 30–90 g. Growth rates were intermediate at 10 °C and lowest at 4 °C for lampreys of all size. Accordingly, host mortality increased with temperature over the 4–20 °C range. At all experimental temperatures, increases in lamprey weight were accompanied by an exponential decline in instantaneous growth rates, a phenomenon also observed for teleosts. Laboratory growth rates at temperatures of 5–15 °C were comparable to rates observed for lampreys in Lake Huron between April and November and agree with the observation that lampreys feed in deeper waters between April and June before moving to warmer, shallower waters during the summer when growth rate increases.

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.

The Impact

A bioenergetics model for growth of lamprey during the parasitic phase was used to estimate food consumption by lampreys and the impact of lamprey feeding on host fishes. Estimates are evaluated by application to several Great Lakes case histories. Temperature and size-dependence of feeding and respiration were sufficient to account for growth dynamics. The model demonstrates that distribution of host fishes, by determining the thermal history of the lamprey, has important effects on lamprey life history and host mortality. Modeled lamprey growth and feeding rates, relative to size of the host, predict a strongly seasonal host mortality rate peaking in autumn. The predicted mortality pattern corresponds with that of independently derived data. Principles of optimal foraging theory applied to lamprey yield a hypothesis that predicts highest wounding and scarring frequencies at intermediate lamprey: host abundance ratios. A second component of the hypothesis predicts seasonal changes in these frequencies as lamprey size increases. Growth rates of lamprey and their host species plus wounding and scarring frequencies are more sensitive indicators of changing abundance ratios and lamprey effects than population changes resulting from predation by lamprey.Key words: sea lamprey, Petromyzon marinus; model, bioenergetics, growth, consumption, fish mortality, 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.

Spawning Behavior

Five species of lampreys are found in the upper three Great Lakes. All species require certain physical factors for successful spawning such as suitable bottom substrates, water velocities, and temperatures. Nest construction (usually started by males) and spawning behavior are similar although some differences exist. In sea lamprey an average spawning act lasts about 2–5 s and is repeated every 4–5 min; generally nesting is monogamous with little polyandrous nesting (1.2–5.0%); average egg production is about 60 000 eggs. An estimated 86% of the eggs of sea lamprey are not deposited in the nests; however, the fertilization and survival of eggs deposited in the nest is high and may approach 90%.Key words: Petromyzon marinus, Ichthyomyzon unicuspis, I. castaneus, I. fossor, Lampetra lamottei, spawning requirement, nest construction, fecundity, nest productivity, water temperature

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

First Time

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.
