“…The sea lamprey Petromyzon marinus is a jawless vertebrate, one of the few surviving species of this ancient group of animals (Guo, Andreou, & Britton, 2017). Its complex life cycle comprises stages in fresh, brackish and saltwater.…”

“…Its complex life cycle comprises stages in fresh, brackish and saltwater. Mating occurs in freshwater in primitive nests built by males to attract females (Guo et al, 2017). Batches of eggs are deposited within the gravel substrate where they reside for an extended larval phase (∼5-6 years) until they emerge during the ontogenetic metamorphosis from larvae (ammocoetes) to young juveniles (transformers) which then drift downstream to deeper areas of low water velocity, before settling into areas of soft sediment (Pinder, Hopkins, Scott, & Britton, 2016).…”

“…In Europe threats to its conservation status include river fragmentation, habitat loss and declining water quality (Pinder et al, 2016), resulting in protected status through designation under Annex II of the EU Habitats Directive (Directive 92/43/EEC). Robust population monitoring is required to ensure that populations achieve the regulatory target of ‘favourable conservation status’, with monitoring strategies usually targeting the freshwater stages, especially nest counts during spawning activity or abundance estimates of ammocoetes in the sediment (Guo et al, 2017; Mateus, Rodríguez-Muñoz, Quintella, Alves, & Almeida, 2012). As ammocoetes remain in freshwater for several years, targeting sediment sites to infer ammocoete presence and / or abundance could provide evidence for the sustainability of sea lamprey populations within specific rivers and habitats.…”

Anthropogenic activities are increasingly threatening aquatic biodiversity, especially anadromous species. Monitoring and conservation measures are thus required to protect, maintain, and restore imperilled populations. While many species can be surveyed using traditional capture and visual census techniques, species that use riverine habitats in a less conspicuous manner, such as sea lamprey Petromyzon marinus, can be more challenging to monitor. Sea lamprey larvae (ammocoetes) can spend several years in freshwater burrowed within soft sediments, inhibiting their detection and assessment. Here we present an environmental DNA (eDNA) assay to detect ammocoetes burrowed in the sediment. We performed a battery of tests that ensured both species-specificity of the assay as well as the capacity to detect ammocoetes when abundances are low. Experiments on burrowing activity suggested that most of the DNA released into the sediment occurs during burrowing. Overall, we demonstrated this new molecular-based tool is an efficient and effective complement to traditional monitoring activities targeting larval stages of sea lampreys.

“…As adults, sea lamprey feed on the blood and tissues of host species, including species of commercial importance such as salmon and lake trout. Invasive sea lamprey impact native fish populations by wounding and often killing the host fishes that they parasitize 18,20 . Following their invasion in the late 1930s, sea lamprey contributed to the catastrophic loss of economically valuable commercial and recreational fisheries in Canada and the United States 21 .…”

Rapid resistance to pesticide control is predicted to evolve in an invasive fish

Xenobiotic resistance is commonly found in species with short generation times such as bacteria, 1 annual plants, and insects. Nevertheless, the fundamental evolutionary principles that govern the 2 spread of resistance alleles hold true for species with longer generation times. One such example 3 could occur with sea lamprey (Petromyzon marinus), a parasitic invasive species in the 4 Laurentian Great Lakes that decimated native fish populations prior to its control with the 5 pesticide 3-trifluoromethyl-4-nitrophenol (TFM). Since the 1950s, tributaries have been treated 6 annually with TFM, where treatments effectively remove most, but not all, larval sea lamprey. 7 We developed an eco-genetic model of sea lamprey to examine factors affecting the evolution of 8 resistance and found that resistance alleles rapidly rise to fixation after 40-80 years of treatment, 9 despite the species' relatively long generation time (4-7 years). The absence of natal homing 10 allows resistant individuals to spread quickly throughout the entire system, but also makes the 11 early detection of resistance challenging. High costs of resistance and density independent 12 reproduction can delay, but not prevent, the onset of resistance. These results illustrate that sea 13 lamprey have the potential to evolve resistance to their primary control agent in the near future, 14 highlighting the urgent need for alternative controls. 15

“…Conversely, as a control measure, light avoidance or attraction by juvenile Sea Lamprey could be capitalized upon by using light arrays in river environments to either curtail downstream movement or guide out‐migrants to collection or trapping facilities. Depending on the goal, manipulation of juvenile Sea Lamprey migration behavior with light cues could be useful for reducing the harmful effects of light pollution on out‐migration in native habitats and for enhancing trap entrainment where Sea Lamprey are invasive (Guo et al 2017).…”

Evaluation of Visible Light as a Cue for Guiding Downstream Migrant Juvenile Sea Lamprey

et al. 2020

Light can modify orientation and locomotory behaviors in fish and has been applied to attract or repel migrant fish by inducing positive or negative phototaxis. Here, recently metamorphosed downstream‐migrating Sea Lamprey Petromyzon marinus were exposed to light cues in several orientations and intensities at night under controlled flowing‐water conditions in a laboratory flume. Behaviors and rates of downstream movement were monitored with overhead cameras and nets. When exposed to low‐intensity white light, 16–23% more Sea Lamprey were captured in a net closest to the light cue array compared to a dark control condition, suggesting some degree of positive phototaxis at low light levels (100 lx at a distance of 1 m from the light source). An interaction with the side of the flume (possibly due to varying flow conditions) and light treatment was also observed. At higher light intensities (1,000 lx at 1 m from the source), Sea Lamprey progressed downstream at a lower rate than was observed during dark conditions. After high‐intensity light treatments, fewer Sea Lamprey were observed in the nets at the downstream end of the flume and more Sea Lamprey were observed in the flume or in the release channel compared to dark control trials. Therefore, some photonegative behavior may be expressed at light levels of 1,000 lx or greater, perhaps as an attempt to avoid detection by predators by remaining stationary or seeking shelter. Light may have utility as a cue used for guidance devices to control Sea Lamprey, but further research is needed to define how light intensity and the environment (turbidity, depth, water velocity, and natural habitat features) influence locomotion, changes in swimming depth, and other behavioral responses of downstream‐migrating juvenile Sea Lamprey.
