Book Description
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.

Lampreys: Biology, Conservation and Control
Author: Margaret F. Docker
Publisher: Springer
ISBN: 9402416846
Category : Science
Languages : en
Pages : 577
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.

Jawless Fishes of the World
Author: Richard Beamish
Publisher: Cambridge Scholars Publishing
ISBN: 1443889644
Category : Science
Languages : en
Pages : 436
Book Description
Hagfishes and lampreys, both examples of jawless fishes, are elongated, eel-like animals lacking paired fins, and are the only living representatives of ancient creatures that gave rise to current species of fish and, eventually, humans. This volume provides an overview of the current status of knowledge on a variety of topics related to jawless fishes, including their taxonomy, zoogeography, phylogeny, molecular biology, evolution, life history, role in the ecosystem, and fisheries and management of hagfishes and lampreys worldwide. This is the first book dealing exclusively with the various aspects of jawless fish species throughout the world. It brings together a number of papers providing new data on jawless fishes, and offers readers a range of useful information within a single reference, reflecting the growing appreciation for hagfishes and lampreys worldwide.
