Behavioural response of Sea Lamprey (Petromyzon marinus) to acoustic stimuli in a small stream
Canadian Journal of Fisheries and Aquatic Sciences, 2020Co-Authors: Victoria L.s. Heath, Scott M. Miehls, Nicholas S Johnson, Dennis M. HiggsAbstract:Sea Lamprey are invasive in the Laurentian Great Lakes and parasitically feed on valued fishes. Migration barriers and selective pesticides are used to control Sea Lamprey, but there is a desire to develop additional control tools such as traps with non-physical deterrents. Sound has been used as a deterrent for other invasive species but its potential for manipulating Sea Lamprey behavior in natural stream conditions remains untested. Here, behavioral responses of upstream migrating adult Sea Lamprey in response to low frequency sounds of 70 or 90 Hz was tracked in a small stream (8 m wide) using passive integrated transponder (PIT) telemetry. The low frequency sounds shifted Sea Lamprey distribution with up to 30% more Sea Lamprey detected on PIT antennas without sound compared to PIT antennas with sound playing. Future studies could continue testing low frequency sounds in larger rivers with larger speakers for use as a natural deterrent at Sea Lamprey barriers to push Sea Lamprey toward traps.

a case study of Sea Lamprey petromyzon marinus control and ecology in a microcosm of the great lakes
Journal of Great Lakes Research, 2020Co-Authors: Nicholas S Johnson, Gale Bravener, Aaron K Jubar, David A Keffer, Peter J Hrodey, Lauren E Freitas, Jesse T Mccarter, Michael J SiefkesAbstract:Abstract The Cheboygan River, Michigan, is the only tributary to the upper Great Lakes where Sea Lamprey (Petromyzon marinus) are known to complete their entire life cycle. The Upper and Lower reaches are separated by the Cheboygan Lock and Dam located about 2 km from Lake Huron. In the Upper River, the Pigeon, Sturgeon, and Maple Rivers provide nursery habitat for larval Sea Lamprey. Burt and Mullett Lakes provide feeding grounds for juvenile Sea Lamprey. Low levels of immigration from Lake Huron occur when adult Sea Lamprey bypass the lock and dam. Lampricide treatment in the Pigeon, Sturgeon, and Maple Rivers began in 1966 and 15 treatments have been conducted to date at a combined cost of $435,000 USD per treatment. Treatments may become more difficult due to recent dam removals in the Pigeon (2016) and Maple Rivers (2018) that expanded habitat available to valued fishes and Sea Lamprey. At present, the landlocked population is less than 200 spawning adults, and those adults are generally smaller and may spawn earlier in the spring than adult Sea Lamprey from Lake Huron. Frequency of Sea Lamprey-induced wounding on steelhead (Oncorhynchus mykiss) and northern pike (Esox lucius) in Mullett Lake is less than 5%. Given increasing challenges of lampricide treatment, efforts to test other means of control such as sterile male release technique is on-going. The Cheboygan River represents a microcosm of the Great Lakes and is useful for learning about Sea Lamprey ecology and testing controls that supplement lampricides and barriers.

estimating age and growth of invasive Sea Lamprey a review of approaches and investigation of a new method
Journal of Great Lakes Research, 2020Co-Authors: Heather A. Dawson, Todd B Steeves, Courtney E Higginsweier, Nicholas S JohnsonAbstract:Abstract We review recent advances in age and growth estimation of invasive Sea Lamprey (Petromyzon marinus) in the Great Lakes and present a more accurate method for growth estimation. To forecast growth and prioritize streams for control actions, Sea Lamprey managers currently use an average daily growth model. Here, a new linear model that included stream and lake as contributing variables was investigated and found to outperform the currently used growth model (roughly a 10 mm difference at age 1). Length-at-age of larvae between ages 1 and 4 were also best forecasted by a linear model with the predictor variables including growing degree days, stream, lake, and larval Lamprey density. The model predicts that larval Sea Lamprey grow faster in warm streams with low densities of Lamprey larvae. More accurate growth models could allow Sea Lamprey control managers to improve decisions concerning how Sea Lamprey control effort is allocated among streams, and could help inform broader modeling efforts evaluating the population demographics of a lake-wide populations exposed to varying control and environmental scenarios. Priority areas for reSearch include investigating if temperatures have increased in Sea Lamprey-producing streams in response to climate change, using close-kin mark-recapture to mark family groups at age 1 to age large larvae and transformers years later, and determining if sex determination is environmentally mediated by larval growth and density.

Registration and application of Sea Lamprey pheromones for Sea Lamprey control in the United States and Canada
Journal of Great Lakes Research, 2020Co-Authors: Kim T. Fredricks, Nicholas S Johnson, Terrance D. Hubert, Mike SiefkesAbstract:Abstract Since the identification of 3-trifluoromethyl-4-nitrophenol as a lampricide in the 1950s, control of Sea Lamprey populations in the Great Lakes has largely relied on lampricides, barriers, and traps. Lampricide treatments target larval Lampreys in tributaries of the Great Lakes. The Great Lakes Fishery Commission oversees Sea Lamprey control efforts and has invested in technologies that may target other life stages to provide a more integrated approach to Sea Lamprey control. One technology under development is the use of pheromones to alter behavior of spawning adults. Pheromones are considered biopesticides, which are substances made from naturally occurring products, or derived from living organisms, or a microorganism, that controls pests. We provide a review of Sea Lamprey management that led to the development of pheromone registration. We also describe the process used to register the first vertebrate pheromone, 3-ketopetromyzonal-24-sulfate (3kPZS) in the United States and Canada and its potential uses in Sea Lamprey control as a supplemental tool to chemical lampricides.

Where you trap matters: Implications for integrated Sea Lamprey management
Journal of Great Lakes Research, 2020Co-Authors: Scott M. Miehls, Nicholas S Johnson, Michael L. Jones, Heather A. Dawson, Alex C. Maguffee, Norine E. DobieszAbstract:Abstract Barriers and pesticides have been used in streams to control Sea Lamprey in the Laurentian Great Lakes for nearly 70 years. Considerable effort has been spent to develop additional control measures, but much less effort has gone toward identifying how or where additional control measures might be cost-effectively integrated into the Sea Lamprey control program. We use a management strategy evaluation model in Lake Michigan to identify the stream types that would be most suitable for deploying traps to remove adults prior to spawning and estimate the likely impact on adult Sea Lamprey abundance in subsequent years under several trapping scenarios relative to status quo abundance. The greatest reduction in lake-wide adult Sea Lamprey abundance predicted by the model resulted when removing adult Sea Lampreys from streams that are difficult for control program personnel to treat with lampricide because lampricide applications would be required less frequently. Additionally, targeting streams which experience regular Sea Lamprey recruitment and streams with low adult Sea Lamprey density should result in reduced lake-wide abundance if trapping costs are relatively low or removal is high. Our results provide direction on where to trap and why, and indicate that trapping may be a valuable part of an integrated Sea Lamprey control approach advancing the goals of the Great Lakes Fishery Commission.

potential changes to the biology and challenges to the management of invasive Sea Lamprey petromyzon marinus in the laurentian great lakes due to climate change
Global Change Biology, 2020Co-Authors: Robert J Lennox, Michael J Siefkes, Charles P Madenjian, Andrew M. Muir, Gale Bravener, Christina K Remucal, Kelly F Robinson, Andrew M Rous, Michael P Wilkie, Daniel P ZielinskiAbstract:: Control programs are implemented to mitigate the damage caused by invasive species worldwide. In the highly invaded Great Lakes, the climate is expected to become warmer with more extreme weather and variable precipitation, resulting in shorter iced-over periods and variable tributary flows as well as changes to pH and river hydrology and hydrogeomorphology. We review how climate change influences physiology, behaviour, and demography of a highly damaging invasive species, Sea Lamprey (Petromyzon marinus), in the Great Lakes, and the consequences for Sea Lamprey control efforts. Sea Lamprey control relies on surveys to monitor abundance of larval Sea Lamprey in Great Lakes tributaries. The abundance of parasitic, juvenile Sea Lampreys in the lakes are calculated by surveying wounding rates on lake trout (Salvelinus namaycush), and trap surveys are used to enumerate adult spawning runs. Chemical control using lampricides (i.e. Lamprey pesticides) to target larval Sea Lamprey, plus barriers to prevent adult Lamprey from reaching spawning grounds are the most important tools used for Sea Lamprey population control. We describe how climate change could affect larval survival in rivers, growth and maturation in lakes, phenology and the spawning migration as adults return to rivers, and the overall abundance and distribution of Sea Lamprey in the Great Lakes. Our review suggests that Great Lakes Sea Lamprey may l benefit from climate change with longer growing Seasons, more rapid growth, and greater access to spawning habitat, but uncertainties remain about the future availability and suitability of larval habitats. Consideration of the biology of invasive species and adaptation of the timing, intensity and frequency of control efforts are critical to the management of biological invasions in a changing world, such as Sea Lamprey in the Great Lakes.

use of physiological knowledge to control the invasive Sea Lamprey petromyzon marinus in the laurentian great lakes
Conservation Physiology, 2017Co-Authors: Michael J SiefkesAbstract:Sea Lamprey (Petromyzon marinus) control in the Laurentian Great Lakes of North America is an example of using physiological knowledge to successfully control an invasive species and rehabilitate an ecosystem and valuable fishery. The parasitic Sea Lamprey contributed to the devastating collapse of native fish communities after invading the Great Lakes during the 1800s and early 1900s. Economic tragedy ensued with the loss of the fishery and severe impacts to property values and tourism resulting from Sea Lamprey-induced ecological changes. To control the Sea Lamprey and rehabilitate the once vibrant Great Lakes ecosystem and economy, the Great Lakes Fishery Commission (Commission) was formed by treaty between Canada and the United States in 1955. The Commission has developed a Sea Lamprey control programme based on their physiological vulnerabilities, which includes (i) the application of selective pesticides (lampricides), which successfully kill sedentary Sea Lamprey larvae in their natal streams; (ii) barriers to spawning migrations and associated traps to prevent infestations of upstream habitats and remove adult Sea Lamprey before they reproduce; and (iii) the release of sterilized males to reduce the reproductive potential of spawning populations in select streams. Since 1958, the application of the Sea Lamprey control programme has suppressed Sea Lamprey populations by ~90% from peak abundance. Great Lakes fish populations have rebounded and the economy is now thriving. In hopes of further enhancing the efficacy and selectivity of the Sea Lamprey control programme, the Commission is exploring the use of (i) Sea Lamprey chemosensory cues (pheromones and alarm cues) to manipulate behaviours and physiologies, and (ii) genetics to identify and manipulate genes associated with key physiological functions, for control purposes. Overall, the Commission capitalizes on the unique physiology of the Sea Lamprey and strives to develop a diverse integrated programme to successfully control a once devastating invasive species.

chemical cues and pheromones in the Sea Lamprey petromyzon marinus
Frontiers in Zoology, 2015Co-Authors: Tyler J. Buchinger, Michael J Siefkes, Barbara S Zielinski, Cory O Brant, Weiming LiAbstract:Chemical cues and pheromones guide decisions in organisms throughout the animal kingdom. The neurobiology, function, and evolution of olfaction are particularly well described in insects, and resulting concepts have driven novel approaches to pest control. However, aside from several exceptions, the olfactory biology of vertebrates remains poorly understood. One exception is the Sea Lamprey (Petromyzon marinus), which relies heavily upon olfaction during reproduction. 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. The critical role of olfaction in mediating the Sea Lamprey life cycle is evident by a well-developed olfactory system. Sea Lamprey use chemical cues and pheromones to identify productive spawning habitat, coordinate spawning behaviors, and avoid risk. Manipulation of olfactory biology offers opportunities for management of populations in the Laurentian Great Lakes, where the Sea Lamprey is a destructive invader. 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.

Using simulation to understand annual Sea Lamprey marking rates on lake trout
Journal of Great Lakes Research, 2020Co-Authors: Jean V. Adams, Michael L. Jones, James R. BenceAbstract:Abstract Sea Lampreys attack fish, killing some and leaving marks on others. Great Lakes fishery managers rely on observed marking rates to assess the success of the Sea Lamprey control program and estimate Sea Lamprey-induced mortality of lake trout. Because marking rates are only observed on survivors of Sea Lamprey attacks, they may not provide a reliable index of actual attack or mortality rates. To investigate the effect of survivor bias, we developed a simulation model representing a single Season (June–December) of Sea Lamprey attacks. Simulated attack rates varied with month and lake trout size; simulated pierce and lethality rates varied with month alone. Surveyed marking rates were represented by simulated survivors in October; true rates were calculated from all simulated lake trout (dead and alive) in December. Simulation results were subsetted to include only those within the range of marking rates actually observed in the Great Lakes. Type A (piercing) marking rates were a good index of the Sea Lamprey attack rate and the Sea Lamprey-induced mortality rate if annual lethality rates were relatively constant. Type B (non-piercing) marking rates were a good index of the Sea Lamprey attack rate and the Sea Lamprey-induced mortality rate if annual pierce rates were relatively constant. Due to the uncertainty surrounding the pierce and lethality rates, we recommend that Sea Lamprey abundance information be incorporated in existing lake trout statistical catch-at-age models via a functional response component relating Sea Lamprey feeding to lake trout abundance, if possible.

forecasting the response of great lakes Sea Lamprey petromyzon marinus to barrier removals
Canadian Journal of Fisheries and Aquatic Sciences, 2018Co-Authors: Alexander Jensen, Michael L. JonesAbstract:A key uncertainty surrounding barrier removals in the Great Lakes is the response of invasive Sea Lamprey populations to realized increases in available habitat for adfluvial species. We addressed this uncertainty by applying a management strategy evaluation model, originally developed to inform Sea Lamprey management in the Great Lakes, to forecast the effects of barrier removal on Lake Michigan Sea Lamprey abundances. We used this model to characterize the response to systematically increasing habitat availability and a specific proposed barrier removal. Our results suggest the removals allow novel production from newly opened habitat and, assuming a fixed budget for Sea Lamprey control, decrease the overall effectiveness of control, leading to disproportionate increases in abundance. The case study demonstrated that evaluating population effects only at the scale of watersheds directly affected by barrier removals would substantially underestimate effects at the scale of Lake Michigan. Similar populati...

rapid evolution meets invasive species control the potential for pesticide resistance in Sea Lamprey
Canadian Journal of Fisheries and Aquatic Sciences, 2018Co-Authors: Michael L. Jones, Jean V. Adams, Robert L. Mclaughlin, Erin S Dunlop, Oana Birceanu, Mark R Christie, Lori A Criger, Julia Mida L Hinderer, Robert M HollingworthAbstract:Rapid evolution of pest, pathogen, and wildlife populations can have undesirable effects, for example, when insects evolve resistance to pesticides or fishes evolve smaller body size in response to harvest. A destructive invasive species in the Laurentian Great Lakes, the Sea Lamprey (Petromyzon marinus) has been controlled with the pesticide 3-trifluoromethyl-4-nitrophenol (TFM) since the 1950s. We evaluated the likelihood of Sea Lamprey evolving resistance to TFM by (i) reviewing Sea Lamprey life history and control; (ii) identifying physiological and behavioural resistance strategies; (iii) estimating the strength of selection from TFM; (iv) assessing the timeline for evolution; and (v) analyzing historical toxicity data for evidence of resistance. The number of Sea Lamprey generations exposed to TFM was within the range observed for fish populations where rapid evolution has occurred. Mortality from TFM was estimated as 82%–90%, suggesting significant selective pressure. However, 57 years of toxicity ...

Defining Economic Injury Levels for Sea Lamprey Control in the Great Lakes Basin
North American Journal of Fisheries Management, 2012Co-Authors: Brian J. Irwin, James R. Bence, Weihai Liu, Michael L. JonesAbstract:Abstract We estimated economic injury levels (EILs) and associated optimal control budgets for Sea Lamprey Petromyzon marinus for each of the Great Lakes using common assumptions and consistent methods. The lake-specific EILs are defined as equilibrium Sea Lamprey abundances below which incremental increases in control expenditures do not pay for themselves in terms of benefits (in the form of increased harvest of desired host species). We assume that Sea Lamprey control efforts result in an increase in the availability of adult hosts for fishery harvest, which provides economic value to society. We used a stochastic population model to simulate the Sea Lamprey life cycle as well as management actions (e.g., treatment of streams with lampricide) over a range of potential control budgets. Prior to running simulations, the model was calibrated for each Great Lake so that resulting forecasts were consistent with recent observed adult (spawning-phase) Sea Lamprey abundance levels given recent control budgets....

waterborne pheromones modulate gonadotropin inhibitory hormone levels in Sea Lamprey petromyzon marinus
General and Comparative Endocrinology, 2020Co-Authors: Yu Wen Chungdavidson, Skye D Fissette, Belinda Huerta, Ugo Bussy, Weiming LiAbstract:Abstract The relationships between pheromone stimuli and neuropeptides are not well established in vertebrates due to the limited number of unequivocally identified pheromone molecules. The Sea Lamprey (Petromyzon marinus) is an advantageous vertebrate model to study the effects of pheromone exposure on neuropeptides since many pheromone molecules and neuropeptides have been identified in this species. Sexually mature male Sea Lamprey release pheromones 7α, 12α, 24-trihydroxy-5α-cholan-3-one 24-sulfate (3 keto-petromyzonol sulfate, 3kPZS) and 7α, 12α-dihydroxy-5α-cholan-3-one-24-oic acid (3-keto allocholic acid, 3kACA) that differentially regulate gonadotropin-releasing hormone (lGnRH) and steroid levels in sexually immature Sea Lamprey. However, the effects of these pheromones on gonadotropin-inhibitory hormones (GnIHs), hypothalamic neuropeptides that regulate lGnRH release, are still elusive. In this report, we sought to examine the effects of waterborne pheromones on Lamprey GnIH-related neuropeptide levels in sexually immature Sea Lamprey. Ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) analyses revealed sex differences in GnIH-related neuropeptide levels in the brain and plasma of immature Sea Lamprey. Exposure to 3kPZS and 3kACA exerted differential effects on GnIH-related neuropeptide levels in both sexes, but the effects were more prominent in female brains. We conclude that Sea Lamprey pheromones regulate GnIH-related neuropeptide levels in a sexually dimorphic manner.

Three Novel Bile Alcohols of Mature Male Sea Lamprey (Petromyzon marinus) Act as Chemical Cues for Conspecifics
Journal of Chemical Ecology, 2017Co-Authors: Ke Li, Anne M. Scott, Joseph J. Riedy, Skye Fissette, Zoe E. Middleton, Weiming LiAbstract:Sea Lamprey, Petromyzon marinus , rely heavily on chemical cues that mediate their life history events, such as migration and reproduction. Here, we describe petromyzone A–C ( 1 – 3 ), three novel bile alcohols that are highly oxidized and sulfated, isolated from water conditioned with spermiated male Sea Lamprey. Structures of these compounds were unequivocally established by spectroscopic analyses and by comparison with spectra of known compounds. Electro-olfactogram recordings showed that 1 at 10^−11 M was stimulatory to the adult Sea Lamprey olfactory epithelium, while 2 and 3 were stimulatory at 10^−13 M. Behavioral assays indicated that 1 is attractive, 2 is not attractive or repulsive, and 3 is repulsive to ovulated female Sea Lamprey. The results suggest that 1 and 2 may be putative pheromones that mediate chemical communication in Sea Lamprey. The identification of these three components enhances our understanding of the structures and functions of sex pheromone components in this species and may provide useful behavioral manipulation tools for the integrated management of Sea Lamprey, a destructive invader in the Laurentian Great Lakes.

Behavioural response of Sea Lamprey (Petromyzon marinus) to acoustic stimuli in a small stream
Canadian Journal of Fisheries and Aquatic Sciences, 2020Co-Authors: Victoria L.s. Heath, Scott M. Miehls, Nicholas S Johnson, Dennis M. HiggsAbstract:Sea Lamprey are invasive in the Laurentian Great Lakes and parasitically feed on valued fishes. Migration barriers and selective pesticides are used to control Sea Lamprey, but there is a desire to develop additional control tools such as traps with non-physical deterrents. Sound has been used as a deterrent for other invasive species but its potential for manipulating Sea Lamprey behavior in natural stream conditions remains untested. Here, behavioral responses of upstream migrating adult Sea Lamprey in response to low frequency sounds of 70 or 90 Hz was tracked in a small stream (8 m wide) using passive integrated transponder (PIT) telemetry. The low frequency sounds shifted Sea Lamprey distribution with up to 30% more Sea Lamprey detected on PIT antennas without sound compared to PIT antennas with sound playing. Future studies could continue testing low frequency sounds in larger rivers with larger speakers for use as a natural deterrent at Sea Lamprey barriers to push Sea Lamprey toward traps.

diel activity of newly metamorphosed juvenile Sea Lamprey petromyzon marinus
PLOS ONE, 2019Co-Authors: Scott M. Miehls, Christopher M Holbrook, Ellen J MarsdenAbstract:Timing of activity, especially for juvenile anadromous fishes undertaking long migrations can be critical for survival. River-resident larval Sea Lamprey metamorphose into juveniles and migrate from their larval stream habitats in fall through spring, but diel timing of this migratory behavior is not well understood. Diel activity was determined for newly metamorphosed Sea Lamprey using day/night net sampling and passive integrated transponder (PIT) telemetry in two natural streams and PIT telemetry in an artificial stream. Downstream migration was primarily nocturnal in all studies. All but one of 372 Sea Lamprey were captured during night sampling in the day/night net collections and all detections (N = 56) for the in-stream PIT telemetry occurred within a few hours after sunset. Most (81% of 48) tagged Lamprey moved downstream during the first night following release and moved at speeds consistent with observed water velocities. During long-term observation of behavior in the artificial stream most Sea Lamprey movement occurred during the night with limited occurrence of movement during daylight hours. Understanding Seasonal and diel timing of downstream migration behavior may allow more effective management of Sea Lamprey for both conservation and control.

Push and pull of downstream moving juvenile Sea Lamprey (Petromyzon marinus) exposed to chemosensory and light cues
Conservation Physiology, 2019Co-Authors: Nicholas S Johnson, Scott M. Miehls, Alex Haro, Michael WagnerAbstract:Visual and olfactory stimuli induce behavioural responses in fishes when applied independently, but little is known about how simultaneous exposure influences behaviour, especially in downstream migrating fishes. Here, downstream moving juvenile Sea Lamprey (Petromyzon marinus) were exposed to light and a conspecific chemosensory alarm cue in a flume and movement were monitored with overhead cameras and nets. When exposed to light, Sea Lamprey were more likely to be captured in a net closest to the light array. When exposed to the alarm cue, Sea Lamprey transit rate through the flume increased, but Sea Lamprey did not avoid the alarm cue plume by moving perpendicular to flow. When the alarm cue and light were applied simultaneously in a push and pull configuration, the alarm cue still triggered enhanced downstream movement (push downstream) and more Sea Lamprey was still captured in the net nearest the light (pull to the side), resulting in twice as many Sea Lamprey being captured in the lighted net relative to controls. To our knowledge, this is the first study using multiple sensory cues in a push-pull configuration to modulate fish outmigration. Push and pull of juvenile Sea Lamprey with sensory cues could be useful to reduce turbine entrainment where native and enhance trap catch where invasive.

Study I: Diel sampling for downstream migrating juvenile Sea Lamprey.
2019Co-Authors: Scott M. Miehls, Christopher M Holbrook, Ellen J MarsdenAbstract:Newly metamorphosed juvenile Sea Lamprey were captured using fyke nets at the mouth of Little Carp River, Michigan, fished from sunrise to sunset (grey bars) and sunset to sunrise (black bars) during November 1, 2011 –November 9, 2011. A total of 372 Sea Lamprey was captured of which 371 were captured during nighttime and one was captured during daytime (asterisk; 11/4/2011). Mean daily water temperature (grey line; secondary y-axis) recorded at 15 min intervals and averaged for each 24-hr period beginning at 00:00 hr.
