Book Description
The stuff of nightmares in both their looks and the wounds inflicted on their victims, sea lampreys (Petromyzon marinus) are perhaps the deadliest invasive species to ever enter the Great Lakes. At the invasion’s apex in the mid-20th century, harvests of lake trout (Salvelinus namaycush), the lampreys’ preferred host fish in the Great Lakes, plummeted from peak annual catches of 15 million pounds to just a few hundred thousand pounds per year—a drop of 98% in only a few decades. Threatening the complete collapse of the fishery, the sea lamprey invasion triggered an environmental awakening in the region and prompted an international treaty that secured unprecedented cooperation across political boundaries to protect the Great Lakes. Fueled by a pioneering scientific spirit, the war on Great Lakes sea lampreys led to discoveries that are the backbone of the program that eventually brought the creature under control and still protects the largest freshwater ecosystem in the world to this day. Great Lakes Sea Lamprey draws on extensive interviews with individuals who experienced the invasion firsthand as well as a trove of unexplored archival materials to tell the incredible story of sea lamprey in the Great Lakes—what started the invasion, how it was halted, and what this history can teach us about the response to biological invaders in the present and future. Richly illustrated with color and black & white photographs, the book will interest readers concerned with the health of the Great Lakes, the history of the conservation movement, and the ongoing threat of invasive species.

Book Description
New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

Book Description
This document augments the dichotomous key crated by Ebener et al. (2003) with photographs taken during the 2002 and 2003 workshops, and it is intended to help fishery agencies implement the King and Edsall (1979) protocol for classifying sea lamprey marks. Their illustrations represented the "idealized" types and stages of sea lamprey marks in comparison with the more complicated marks often observed in the field. We combined the original King and Edsall (1979) photographic illustrations with photographs made at the five workshops to create this sequel to the 1979 field guide.

Book Description
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.

Book Description
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.

Book Description
This volume, cataloging and analyzing the current science on the state of Lake Michigan, is an important part of Great Lakes recovering science. It carries forward the singular contribution that the binational Great Lakes scientific community has made not only to restoring the Great Lakes but also to the world's body of knowledge about large lake ecology, the long-range transport of pollutants, and the importance of habitat in ensuring ecosystem health.

Book Description
To maintain thriving, sustainable fisheries in the Laurentian Great Lakes, an understanding of the numerous and complex ecological, societal, economic, management, and policy issues surrounding them is critical. This incisive study provides a collaborative, interjurisdictional, and multi-use perspective that is shaped by the United states and Canada together as part of their shared governance of these waters. This book offers an informed look at the Great Lakes fisheries and their ecosystems, as the contributors examine both the threats they have faced and the valuable opportunities they provide for basin citizens and industries. Divided into four sections--the Great Lakes region, Great Lakes Fisheries, Fisheries case studies, and outlook for the Future--this is a valuable and up-to-date tool for students, researchers, policymakers, and managers alike.
