"This document describes sampling activities and summarizes results from 2011 to 2021 trapping surveys of Morison Creek Lamprey, a unique population of Western Brook Lamprey (Lampetra richardsoni). Morrison Creek Lamprey is an endangered species at risk, present only in the Morrison Creek watershed in Courtenay, British Columbia. The trapping activities reported here not only help to monitor the population, but have also provided an opportunity to identify conservation concerns and protect the species and its habitat. The data provided in this document shows persistence of the population within its range, and should not be used as an indicator of population abundance or relative abundance"--Abstract, page vi.

"Passive downstream traps were placed in the main stem and headwaters of Morrison Creek, Courtenay, BC as a part of ongoing monitoring of Morrison Creek Lamprey, a federally-listed endangered lamprey species found only in the Morrison Creek watershed. The total numbers of lamprey trapped were low; however, they are comparable to the results of other trapping studies since 2011. Although methods are the same, catches remain much lower than those reported in the late 1970s and 1980s when the population was discovered. The causes of this decline in catch are unknown. Recommendations are to continue monitoring the population both in the main stem and headwaters through trapping studies and, using our best knowledge, ensure the habitat is maintained in a manner which supports the functions of the population and mitigates the effects of harm"--Abstract, page v.

"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.

"The Western Brook Lamprey - Morrison Creek Population (Lampetra richardsoni), hereafter referred to as Morrison Creek Lamprey, was assessed by COSEWIC as Threatened in April 1999. In May 2000, the species' status was re-examined by COSEWIC and designated Endangered, and subsequently listed under the Species at Risk Act as Endangered in June 2003. In July of 2007 the final Recovery Strategy for the Morrison Creek Lamprey (Lampetra richardsoni var. marifuga) in Canada (NRTMCL 2007) was posted to the Species at Risk Public Registry. An updated COSEWIC assessment in 2010 confirmed the species' status as Endangered. The recovery goal as identified in the Recovery Strategy for this species is to "secure its long-term viability within its natural range." This report documents the progress of Recovery Strategy implementation for Morrison Creek Lamprey. It summarizes progress that Fisheries and Oceans Canada, the Province of British Columbia's Ministry of Environment, and other interested parties have made towards achieving the goal and objectives set out in the Recovery Strategy including: conducting new research and monitoring activities (including advancing studies to support the identification of critical habitat); and completing management activities that help Canadians reduce impacts on, and better understand the threats to, Morrison Creek Lamprey"--Executive summary.

The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.

This book, published in two volumes, provides the most comprehensive review of lamprey biology since Hardisty and Potter’s “The Biology of Lampreys” published more than 30 years ago. This second volume offers a synthesis of topics related to the lamprey gonad (e.g., lamprey sex ratios, sex determination and sex differentiation, sexual maturation, and sex steroids), the artifical propagation of lampreys, post-metamorphic feeding and the evolution of alternative feeding and migratory types, the history and status of sea lamprey control in the Laurentian Great Lakes and Lake Champlain, and an overview of contributions of lamprey developmental studies for understanding vertebrate evolution.

Global Change in Marine Systems analyses and appraises societal and governing responses to change affecting marine social and ecological systems around the world. Acknowledging the stakes – local societies that depend on marine systems for food, livelihoods and wellbeing can suffer great hardship – this book highlights and explains similarities and distinctions between successful and unsuccessful responses. The book presents an analytical framework (‘I-ADApT’) that enables decision-makers to consider possible responses to global change based on experiences elsewhere. Here an international group of researchers from the natural and social sciences apply the ‘I-ADApT’ framework to twenty enlightening case studies, covering a wide range of marine systems challenged by critical global change issues around the world. The innovative research presented here guides marine system researchers, policymakers, decision-makers and practitioners in responding to global change in a timely and appropriate manner. It will appeal to students and researchers interested in environmental studies, natural resources, marine resources, environmental sociology, sustainability, and climate change.
