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.

Excerpt from Sea Lamprey Spawning Runs in the Great Lakes in 1950 As the result of a special Congressional appropriation (public law 2h9-815t Congress) the Service's sea lamprey investigations were greatly expanded at the beginning of the 1950 calendar year. A per manent staff of seventeen individuals with an equal number of seasonal employees was assigned specifically to these investigations. Permission to occupy the former Hammond Bay Coast Guard Station on northern Lake Huron was obtained from that agency and the nine buildings and other properties involved are now known as the Hammond Bay Fishery Laboratory. Alterations and additions to provide office and laboratory space, rune ning-water aquaria and tank rooms, work shop, net-shop, boathouse, and raceway facilities have been completed or are in progress. Considerable time and energy have been expended to equip this field station and in training the permanent staff.

Most of the experimental lampreys were mature and rip after 14 to 18 months of parasitic life. They exhibited signs of irreversible physical degeneration which precedes death. Three specimens were immature at 14, 18, and 26 months in aquariums, thus indicating that under certain conditions, lampreys may extend their parasitic phase.
