Abstract Pacific lamprey (Entosphenus tridentatus) is a First Food of Native Americans. Declines in lamprey abundance due to dam construction and habitat loss have curtailed traditional harvest opportunities. Artificial propagation is an emerging recovery tool for this imperiled species, and other lamprey species in Finland and Japan. To manage disease risk at prospective lamprey hatcheries, it is critical to understand the pathogens and parasites most likely to affect lamprey and other fish, both in culture and in the wild. We assembled data from regional fish health laboratories to assess pathogen prevalence in Pacific lamprey sampled from various sources (518 adults, 275 larvae, and one juvenile). In adults,...

Sexually immature, adult river lamprey Lampetra fluviatilis in the upstream migratory phase, were shown to be attracted to water conditioned with ammocoete larvae when tested using a two-choice flume. Although preliminary, the data suggest that migrating adult river lamprey may be attracted to larval putative pheromone as recorded in sea lamprey Petromyzon marinus.
