“…The sea lamprey is an extant agnathan (Smith et al, 2013) with a highly complex life cycle consisting of a filter-feeding larval (often referred to as an ammocoete) stage lasting 3-7 years, before undergoing a highly synchronized metamorphosis into a juvenile (Youson, 2003). With the exception of invasive sea lamprey populations in the Great Lakes (see Siefkes, 2017;Wilkie et al, 2019, for reviews), sea lampreys are anadromous spending their larval phase in FW and their blood-feeding adult phase in SW before returning to FW to spawn (Beamish & Potter, 1975). Stenohaline ammocoetes exhibit osmoregulatory strategies similar to FW teleost fishes (i.e., active ion uptake coupled with restriction of passive ion loss).…”

The role of lamprey epithelium tight junctions (TJs) in the regulation of salt and water balance is poorly understood. This study reported on claudin (Cldn) TJ protein transcripts of pre‐metamorphic larval and post‐metamorphic juvenile sea lamprey (Petromyzon marinus) and the transcriptional response of genes encoding Cldns to changed environmental ion levels. Transcripts encoding Cldn‐3b, ‐4, ‐5, ‐10, ‐14, ‐18 and ‐19 were identified, and mRNA expression profiles revealed the organ‐specific presence of cldn‐5 and ‐14, broad expression of cldn‐3b, ‐4, ‐10, ‐18 and ‐19 and spatial differences in the mRNA abundance of cldn‐4, ‐3b and ‐14 along the ammocoete intestine. Expression profiles were qualitatively similar in ammocoetes and juvenile fishes. Transcript abundance of genes encoding Cldns in osmoregulatory organs (gill, kidney, intestine and skin) was subsequently investigated after exposure of ammocoetes to ion‐poor water (IPW) and juveniles to hyperosmotic conditions [60% sea water (SW)]. IPW‐acclimated ammocoetes increased mRNA abundance of nearly all cldns in the gill. Simultaneously, cldn‐10 abundance increased in the skin, whereas cldn‐4, ‐14 and ‐18 decreased in the kidney. Ammocoete cldn mRNA abundance in the intestine was altered in a region‐specific manner. In contrast, cldn transcript abundance was mostly downregulated in osmoregulatory organs of juvenile fish acclimated to SW – cldn‐3b, ‐10 and ‐19 in the gill; cldn‐3b, ‐4, ‐10 and ‐19 in the skin; cldn‐3b in the kidney; and cldn‐3b and ‐14 in the intestine. Data support the idea that Cldn TJ proteins play an important role in the osmoregulatory physiology of pre‐ and post‐metamorphic sea lamprey and that Cldn participation can occur across organs, in an organ‐specific manner, as well as differ spatially within organs, which contributes to the regulation of salt and water balance in these fishes.

“…Sex pheromones to attract females are secreted by males, which precede females onto the gravel spawning grounds ( Figure 1; Johnson, Yun, Thompson, Brant, & Li, 2009). Although eradication of sea lamprey in the Great Lakes remains impractical, a program to control their populations has helped rehabilitate the fisheries in the Great Lakes and provides net benefits to the regional economy (Lupi, Hoehn, & Christie, 2003;Siefkes, 2017;Wilkie, Hubert, Boogaard, & Birceanu, 2019).…”

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, behavior, and demography of a 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 is 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 and 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 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 is critical to the management of biological invasions in a changing world, such as sea lamprey in the Great Lakes.

“…Larval sea lamprey are vulnerable to control measures as a result of their relatively sedentary nature in streambeds. Tributaries infested with larval sea lamprey are treated with selective pesticides (hereafter lampricides) that interfere with oxidative ATP production, essentially breaking the energy production cycle at the cellular level (Birceanu et al 2011; see Wilkie et al 2019 for synthesis of current lampricide control in the Great Lakes). The area of infestation is confined using barriers to limit the range of adult sea lamprey migrating upstream to spawn.…”

A major duty of the Great Lakes Fishery Commission (GLFC), created in 1955, was the development a program of eradication or management of sea lamprey populations in the Great Lakes for the protection of the Great Lakes fishery. Beginning in the 1980s the GLFC shifted sea lamprey control to an integrated pest management model seeking to deploy control measures which target multiple life stages. Currently control efforts focus on limiting the area of infestation using barriers to migratory adults and eradication of larvae from streams using selective pesticides. Feedback on program effectiveness is obtained by trapping migratory adult lamprey at a series of index sites around the basin. The GLFC continues to support multiple research initiatives to develop additional control, improve current control measures, and further advance the sea lamprey control program. During the past six decades sea lamprey control in the Great Lakes has evolved as the research program has identified technological advances. Here we summarize the current state and recent advancements for two of the sea lamprey control program’s core elements, barriers and traps, highlight challenges to be addressed to continue the advancement of these program elements, and provide a series of research questions to spur interest within the research community. Further, because considerable information about these program elements is scattered among grey literature and technical reports, we summarize the history of barriers and traps in sea lamprey control in the included appendices to provide relevant program background to anyone interested in pursuing these research topics.
