Abstract

Invasive sea lamprey ( Petromyzon marinus ) are controlled in the Great Lakes with 4-nitro-3-(trifluoromethyl)phenol (commonly 3-trifluoromethyl-4-nitrophenol or TFM). The proper amount of TFM must be applied during treatments to effectively kill larval sea lamprey while minimizing impacts to non-target species. In this study, bioassay tests were conducted in May, July, and September in a portable test trailer at six larval sea lamprey infested rivers in Michigan to determine potential seasonal changes in sensitivity of larval sea lamprey to TFM. Larvae greater than 60 mm were collected from each stream and exposed for 12 h in TFM-treated stream water using two independent continuous-flow diluter systems. A suite of water chemistries and larval physiological parameters were collected during the tests and modeled as potential predictors of seasonal changes in the sensitivity of larval sea lamprey to TFM. The observed minimum lethal concentrations to larval sea lamprey were 0–40% lower (May), 8% lower–59% higher (July), and 49–117% higher (September) than sea lamprey control personnel treatment prediction charts. Water temperature, liver glycogen content, and time of year were strongly associated with seasonal differences in TFM sensitivity, offering sea lamprey control personnel more exact predictions to limit potential residual lamprey surviving future treatments.

Groundwater nutrient contributions to surface water in the upper Maumee River basin

Harmful algal blooms triggered by nutrient loading have negatively affected Lake Erie water quality for decades, but the role groundwater plays in transporting nutrients to tributary streams is unclear. Here, we apply a multi-scale approach to investigate groundwater nitrogen (N) and phosphorus (P) dynamics at the field scale, along a groundwater flow path, and at the Maumee River basin scale. Unsaturated zone monitoring indicates that macropore flow is the primary mechanism for N and P leaching with nitrate and orthophosphate (OP) concentrations from macropore samplers more than double those from soil-matrix samplers. Shallow (< 4.5 m) groundwater nitrate concentrations indicate the timing of saturated-zone nitrate fluxes is crop dependent with more nitrate mobilized during the maize growing season whereas concentrations below soybeans can remain elevated (> 3 mg/L) through winter months. A three-end-member hydrograph analysis for the upper Maumee River basin indicates that tile drains transport most subsurface N and P with greater than 15,000 kg per day of nitrate transported between January and May. Orthophosphate concentrations in tile drainage at an edge-of-field site correlate well with concentrations in a nearby tributary of the Maumee River. While runoff is the dominant source of OP loading, tile drainage and groundwater discharge contributed an estimated 36% of OP load during a 2018–2022 analysis period with most subsurface loading occurring between January and March. These findings highlight how best management practices (such as cover crops and tile drainage control structures) can be used to help limit leaching and tile effluent during the nongrowing season.

Low recapture rates preclude survival estimates of larval and juvenile sea lamprey in the Lake Erie basin

Our goal was to estimate survival of non-native larval and juvenile sea lamprey ( Petromyzon marinus ) in the Lake Erie basin and compare estimates with those from Lakes Huron and Michigan. Accomplishing the goal would inform decisions about allocating limited control resources among the Laurentian Great Lakes to protect valued fish stocks. Between 2012 and 2018, coded-wire tagged (CWT) larvae and juveniles were released in three Lake Erie tributaries where they were unlikely to experience control program-induced mortality. Adult sea lamprey returning to tributaries to spawn were captured and scanned for CWTs, with the objectives being to determine (1) if survival differed between the Saint Clair River and other sea lamprey-producing tributaries of Lake Erie, and (2) if survival in Lake Erie differed from estimates in Lakes Huron and Michigan. No tagged larvae were recaptured as adults, preventing survival estimation. Recovery probability of tagged juveniles released in the Saint Clair River in the adult stage was about half that of other streams, but statistical comparisons were limited due to low recovery (Objective 1). Estimated lake-wide adult sea lamprey abundance was at record lows when tagged larvae were expected to return as adults. Simulations suggest that survival estimates of larval and juvenile sea lamprey in Lake Erie may be less than survival estimated in Lakes Huron and Michigan (Objective 2). Understanding survival rates of sea lamprey across the Great Lakes and individual streams could guide control effort allocation, although alternative methods for quantifying survival may be needed given the challenges encountered here.

Short-term outcomes of juvenile sea lamprey feeding on lake trout vary among parasite–host number combinations in a controlled laboratory setting

The parasitic juvenile stage of the invasive sea lamprey ( Petromyzon marinus ) causes host injury and mortality in the Laurentian Great Lakes, yet laboratory feeding studies have generally used single-host or simple host-choice designs. We conducted controlled 7-d trials to quantify lake trout ( Salvelinus namaycush ) wounding, sea lamprey recovery, positive net mass change, growth, and wound location across four lamprey–host number combinations: 1:3, 6:6, 6:3, and 18:9. Candidate models evaluated whether outcomes were better explained by number combination, lamprey abundance, lamprey:host ratio, or separate lamprey and host effects. Across 27 trials, 70 of 135 lake trout (51.9%) were wounded, producing 113 wounds. Wounding was lowest in 1:3 (sea lamprey:host) and highest in 18:9, where 72.2% of hosts were wounded, and wound intensity was 1.33 wounds per host. In pooled descriptive models, each additional stocked sea lamprey was associated with a 13% increase in the odds that an exposed lake trout was wounded and an 8.3% increase in wound intensity per host. Among 173 recovered sea lamprey, 104 (60.1%) exhibited positive net mass change. This probability varied among number combinations, whereas candidate predictors provided little improvement over constant-mean models for continuous growth. Among lamprey exhibiting positive net mass change, intercept-only models were best supported, indicating little evidence that growth magnitude varied systematically among combinations. Wounds were distributed non-randomly among host body regions relative to proportional surface area. Short-term outcomes, therefore, varied among the tested parasite–host number combinations.
