Diel activity of newly metamorphosed juvenile sea lamprey (Petromyzon marinus)
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...
Miehls, Scott M.; Holbrook, Christopher; Marsden, J. Ellen Lateral and vertical distribution of downstream migrating juvenile sea lamprey
Sea lamprey is considered an invasive and nuisance species in the Laurentian Great Lakes, Lake Champlain, and the Finger Lakes of New York and is a major focus of control efforts. Currently, management practices focus on limiting the area of infestation using barriers to block migratory adults, and lampricides to kill ammocoetes in infested...
Sotola, V. Alex; Miehls, Scott M.; Simard, Lee G.; Marsden, J. Ellen Assessment of PIT tag retention and post-tagging survival in metamorphosing juvenile Sea Lamprey
Background: Passive integrated transponder (PIT) tags have been used to document and monitor the movement or behavior of numerous species of fishes. Data on short-term and long-term survival and tag retention are needed before initiating studies using PIT tags on a new species or life stage. We evaluated the survival and tag retention of 153...
Simard, Lee G.; Sotola, V. Alex; Marsden, J. Ellen; Miehls, Scott M. Test of a non-physical barrier consisting of light, sound, and bubble screen to block upstream movement of sea lamprey in an experimental raceway
Control of the invasive Sea Lamprey Petromyzon marinus is critical for management of commercial and recreational fisheries in the Laurentian Great Lakes. Use of physical barriers to block Sea Lampreys from spawning habitat is a major component of the control program. However, the resulting interruption of natural streamflow and blockage...
Miehls, Scott M.; Johnson, Nicholas S.; Hrodey, Pete J. Assessment of pulsed DC electric field to guide downstream migrating sea lamprey in experimental flume at USGS Conte Anadromous Fish Lab, Turners Falls, MA (December 2013)
This is a tabular data set that contains records of water velocity, depth, temperature and trial information such as start and stop times and date for experimental trials testing the effect of an electric field on the movement patterns and distribution of juvenile sea lamprey moving downstream in an experimental flume. Distribution is recorded for...
Miehls, Scott M.; Johnson, Nicholas; Haro, Alexander J. Electrical guidance efficiency of downstream-migrating juvenile Sea Lamprey decreases with increasing water velocity
We tested the efficacy of a vertically oriented field of pulsed direct current (VEPDC) created by an array of vertical electrodes for guiding downstream-moving juvenile Sea Lampreys Petromyzon marinus to a bypass channel in an artificial flume at water velocities of 10–50 cm/s. Sea Lampreys were more likely to be captured in the bypass channel...
Miehls, Scott M.; Johnson, Nicholas S.; Haro, Alexander A portable trap with electric lead catches up to 75% of an invasive fish species
A novel system combining a trap and pulsed direct current electricity was able to catch up to 75% of tagged invasive sea lamprey Petromyzon marinus in free-flowing streams. Non-target mortality was rare and impacts to non-target migration were minimal; likely because pulsed direct current only needed to be activated at night (7 ...
Johnson, Nicholas S.; Miehls, Scott M.; O'Connor, Lisa M.; Bravener, Gale; Barber, Jessica; Thompson, Henry T.; Tix, John A.; Bruning, Tyler Evidence that sea lampreys (Petromyzon marinus) complete their life cycle within a tributary of the Laurentian Great Lakes by parasitizing fishes in inland lakes
The sea lamprey (Petromyzon marinus) invaded the upper Laurentian Great Lakes and feeds on valued fish. The Cheboygan River, Michigan, USA, is a large sea lamprey producing tributary to Lake Huron and despite having a renovated dam 2 km from the river mouth that presumably blocks sea lamprey spawning migrations, the watershed upstream of the dam...
Johnson, Nicholas S.; Twohey, Michael B.; Miehls, Scott M.; Cwalinski, Tim A; Godby, Neal A; Lochet, Aude; Slade, Jeffrey W.; Jubar, Aaron K.; Siefkes, Michael J. Guiding out-migrating juvenile sea lamprey (Petromyzon marinus) with pulsed direct current
Non-physical stimuli can deter or guide fish without affecting water flow or navigation and therefore have been investigated to improve fish passage at anthropogenic barriers and to control movement of invasive fish. Upstream fish migration can be blocked or guided without physical structure by electrifying the water, but directional downstream...
Johnson, Nicholas S.; Miehls, Scott M. Use of oviduct-inserted acoustic transmitters and positional telemetry to estimate timing and location of spawning: a feasibility study in lake trout, Salvelinus namaycush
Background Oviduct-inserted transmitters have shown promise for determining precise location of spawning in fishes. Use of traditional manual tracking to locate expelled oviduct transmitters is laborious and accurate estimates of time of transmitter expulsion require frequent surveys. We tested the feasibility of using oviduct-inserted...
