“…These factors include where lamprey occur when they detach from their final marine host (Spice et al, 2012), behavioural cuing to river flow (Meckley et al, 2014, 2017; Vrieze et al, 2011) and the presence of migratory pheromones (i.e. bile acids) released by larval lamprey occupying freshwater streams (Robinson et al, 2009; Yun et al, 2011; see also reviews in Buchinger et al, 2015 and Fissette et al, 2021). The mechanisms for how, when, where and why adult Pacific lamprey select tributaries during their spawning migrations are thought to be like the above cues for lamprey with respect to attraction to flow and pheromones (Moser et al, 2015).…”

Artificial obstructions such as dams are a key limiting factor or threat to adult Pacific lamprey (Entosphenus tridentatus) attempting to access upstream spawning habitats. Nevertheless, lamprey counted during dam passage (dam counts) is useful for monitoring abundance trends of these fish. We describe the trends in lamprey dam counts during 2005–2020 at Leaburg Dam (6.7 m height) on the McKenzie River (Oregon, USA). Despite similar flow volumes at each of two fish ladders, most lampreys in most years passed Leaburg Dam via the right bank fish ladder (vertical slot design) rather than the left bank fish ladder (half Ice Harbor). Counts ranged between 32 and 176 lampreys per year (median = 71.5 individuals). Akaike Information Criterion revealed the best fit General Additive Model (GAM) that described the cumulative proportion of lamprey passage included ‘year’, ‘day of the year’ and ‘river flow’, as opposed to other GAMs that included fewer of these variables or that included ‘water temperature’. Lamprey generally began passing during consecutive days of decreasing river flows, with most passing during annual low flows during June–August each year. In addition, total annual dam counts were strongly correlated with the sum of mean daily river flows. Thus, higher annual river flows correlate with earlier and more lamprey passage, but peak passage occurs at annual low flows. Mean daily water temperature ranged between 7.8 and 14.9°C during lamprey passage.

“…After two (Morkert et al, 1998 ) to seven years (Manion & Smith, 1978 ) in the larval stage, larvae undergo metamorphosis, migrate to the Great Lakes, and feed on fishes for 12–18 months. Adult sea lampreys do not return to natal streams to spawn (Bergstedt & Seelye, 1995 ), but instead, stream selection is guided by chemosensory cues released by larval sea lamprey (Fissette et al, 2021 ). Therefore, population structure of sea lamprey is weak relative to homing fishes (Bryan et al, 2005 ).…”

The sea lamprey (Petromyzon marinus) is an invasive species in the Great Lakes and the focus of a large control and assessment program. Current assessment methods provide information on the census size of spawning adult sea lamprey in a small number of streams, but information characterizing reproductive success of spawning adults is rarely available. We used RAD‐capture sequencing to genotype single nucleotide polymorphism (SNP) loci for ~1600 sea lamprey larvae collected from three streams in northern Michigan (Black Mallard, Pigeon, and Ocqueoc Rivers). Larval genotypes were used to reconstruct family pedigrees, which were combined with Gaussian mixture analyses to identify larval age classes for estimation of spawning population size. Two complementary estimates of effective breeding size (Nb), as well as the extrapolated minimum number of spawners (Ns), were also generated for each cohort. Reconstructed pedigrees highlighted inaccuracies of cohort assignments from traditionally used mixture analyses. However, combining genotype‐based pedigree information with length‐at‐age assignment of cohort membership greatly improved cohort identification accuracy. Population estimates across all three streams sampled in this study indicate a small number of successfully spawning adults when barriers were in operation, implying that barriers limited adult spawning numbers but were not completely effective at blocking access to spawning habitats. Thus, the large numbers of larvae present in sampled systems were a poor indicator of spawning adult abundance. Overall, pedigree‐based Nb and Ns estimates provide a promising and rapid assessment tool for sea lamprey and other species.

Fish use odor to avoid exposure to predation and disease. Harnessing these odors as repellents is proving useful for management initiatives that conserve native species or control invasive populations. Here, we evaluated the behavioral response of invasive sea lamprey to putrescine, a decay molecule that many prey organisms avoid. Putrescine is found in tissue extracts that contain sea lamprey alarm cue, and human saliva, two mixtures known to elicit flight and avoidance responses in migratory sea lamprey. We used two behavioral assays to evaluate metrics of repellency: behavioral preference (space use) and change in activity rates and found context-dependent results. In smaller assays with individual fish, we found that putrescine had no effect on sea lamprey activity but did induce avoidance. In larger assays with multiple animals, sea lamprey did not avoid putrescine. Our results also showed consistent changes in activity and avoidance behavior in sea lamprey exposed to alarm cue in the smaller assay, concluding that this design could prove useful as a high-throughput screening tool. We also investigated a novel odor identified in sea lamprey skin, petromyzonacil, and found no behavioral effects to this odor on its own or in synergy with putrescine. Our results show limited evidence that putrescine acts as robust repellent for sea lamprey and highlight the importance of environmental context when interpreting avoidance behavior in laboratory settings.
