Opportunistic observations of nest building and spawning of the endangered western brook lamprey, Morrison Creek population (Lampetra richardsoni) / by Joy Wade and Paul Grant. : Fs97-4/3251E-PDF

"Western Brook Lamprey (Lampetra richardsoni), Morrison Creek population is an endangered species, endemic to the Morrison Creek watershed in Courtenay, British Columbia. Despite the risk of extinction the species is currently facing, many knowledge gaps still exist which may limit recovery or conservation efforts. Therefore, basic habitat and biological data were collected in 2021 from lamprey actively spawning in Morrison Creek to help better inform the habitat requirements for nest building and spawning. Specifically, this report documents the conditions under which lamprey were observed nest building or spawning and provides recommendations for future research"--Abstract, page v.
