Lake trout (Salvelinus namaycush) were discovered in Yellowstone Lake in 1994 and their population expanded dramatically despite intensive suppression. The lake is species-depauperate, with no major lake trout embryo predators. We hypothesized that without this predation threat, lake trout free embryo feeding and growth may be greater than in their...

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 tributa...

Passive integrated transponder (PIT) tags have been used to document and monitor the movement, behavior, or survival of numerous species of fishes. Data on short- 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 metamorphos...

Sea lamprey (Petromyzon marinus) research and control efforts regularly target larval and adult stages, but little focus has been placed on the metamorphosing juvenile (transformer) stage because of logistical challenges working through the winter. This study was designed to determine the spatial and temporal patterns of out-migrating transformers....

Passive Integrated Transponder (PIT) tags have been used to document and monitor the movement or behavior of numerous species of fishes. When initiating a study using PIT tags, it is important to document immediate and post-surgery survival, as well as tag retention. We evaluated PIT tag retention and survival of sea lamprey (Petromyzon marinus) tr...
