Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.

The success of the first volume of The Biology of Sea Turtles revealed a need for broad but comprehensive reviews of major recent advances in sea turtle biology. Biology of Sea Turtles, Volume II emphasizes practical aspects of biology that relate to sea turtle management and to changes in marine and coastal ecosystems. These topics include the interactions of humans and sea turtles, an introduction to sea turtle anatomy, sensory and reproductive biology, sea turtle habitat use and ecology, stress and health, and the maintenance of captured animals. This volume provides both historical and up-to-date information.

The spotted seatrout is an important species not only for recreational and commercial fisheries, but also as an integral part of many estuarine ecosystems. As one of the few fishes that live its entire life within an estuarine system, the species has tremendous potential as a monitor or sentinel for estuarine conditions. Prepared by the foremost authorities in their respective fields, Biology of the Spotted Seatrout presents an up-to-date summary of what is known about the basic biology of this important species.This innovative reference provides current life history information on this species for the expressed purpose of beginning the task of assessing differences in estuarine restricted sub-populations of spotted seatrout. It serves as a model of a biological summary directed toward determining which of the life history parameters will most aptly serve as bioindicators to meet overall environmental management needs. It integrates estuarine specific life history features into the overall management of both estuaries and an estuarine dependent fishery.Biology of the Spotted Seatrout includes a classic systematic approach to studying the relationships between seatrout genera as well as a more modern approach to investigating intra- and inter-estuarine differences in genetic structure. Ecologists, fisheries biologists and managers, and environmental scientists worldwide will be able to use the information presented in this book as a model on which to establish a database of information to be used to assess and compare estuarine conditions and environmental health. This valuable book serves as a blueprint for bringing together the biological criteria necessary to begin landscape scale comparisons of estuaries based on the biological information of totally estuarine dependent species, such as the spotted seatrout.

Highlighting the growing importance of the sticklebacks as a model species in emerging fields such as molecular genetics, genomics, and environmental toxicology, Biology of the Three-Spined Stickleback examines data from researchers who use studies of the stickleback to address a wide range of biological issues. This state-of-the-art volume is the first comprehensive review of the biological research on this important fish in more than a decade.The book presents current knowledge on the geographic and genetic variation of the ubiquitous three-spined stickleback and explores the possibility of any subdivision within currently recognized stickleback species. It provides a summary of important new molecular tools available, and how these tools can be used to study the genetic architecture and molecular basis of evolutionary change in different stickleback populations around the world. The book also lays out their physiology, historical factors, geographic distribution, and describes the features of their biology that seem to promote rapid speciation. It covers reproductive behavior in chronological order, and the mechanisms and selection pressures behind the activities that sticklebacks perform during the different phases of the breeding season. Full of cutting-edge data, the book discusses the umwelt of the three-spine stickleback, with particular reference to how that world interacts with and shapes intraspecific communication during the breeding season. It covers developments in stickleback reproductive physiology from 1991 onward and summarizes studies performed — mainly within the fields of behavioral ecology and physiology — on some of the less-studied stickleback species. The book touches on the biology, in particular the behavioral ecology, of the 15-spined stickleback. Emphasizing the importance of the sticklebacks to a variety of disciplines, this book presents information that is both extensive and authoritative.

The large amount of information on fish reproduction available is not always readily accessible to all interested parties. Written to appeal to aquaculturalists, conservation managers, and scientific researchers, Methods in Reproductive Aquaculture provides an overview of available techniques and addresses ways to improve depleted stocks of endangered fish and other species.The book focuses on gamete quality and management, exploring new objectives and areas of application and research, and new tools to deal with some aspects in reproduction of aquatic species. It begins with an examination of basic methods and techniques for gamete extraction, mainly sperm collection and egg stripping in different species, then describes techniques of spawning stimulation in males and females. The volume then highlights sperm and egg quality evaluation and considers sperm analysis from a practical broodstock management point of view and in the selection of appropriate breeders. The book goes on to discuss techniques used for artificial fertilization and the procedures for obtaining modified offspring. It introduces cryopreservation procedures for sperm, oocytes, and embryos, then discusses the materials and facilities required for gamete preparation and freezing-thawing procedures. The book concludes with an extensive section detailing sperm cryopreservation protocols for fifty-six marine and freshwater species. Unique in its focus on both marine and freshwater aquaculture of fishes, the book provides information on endangered, highly profitable species for aquaculture or fisheries and species with high potential in laboratory research. Presenting the available information in an easily understandable way, this is not merely a techniques book, but also a complete guide to fish reproduction, gamete quality, and management.

Chapters include discussions of satellite-linked tags, used to track whale shark movements; genetic sequencing, to examine evolutionary adaptations; even the use of underwater ultrasound units to investigate the species’ reproduction. The editors hope that by collating what is known, they can make it easier for future researchers, conservationists, and resource managers to fill some of the remaining knowledge gaps, and provide the information they need to join the team.As you work your way through this book, we hope that you will develop a sense of awe and marvel at all of our good fortune to share the ocean, and the planet, with this utterly extraordinary species.

Suppose you were designing a marine mammal. What would they need to live in the ocean? How would you keep them warm? What design features would allow them to dive for very long periods to extreme depths? Do they need water to drink? How would they minimize the cost of swimming, and how would they find their prey in the deep and dark? These questions and more are examined in detail throughout Marine Mammal Physiology, which explores how marine mammals live in the sea from a physiological point of view. This undergraduate textbook considers the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. It focuses on the physiological and biochemical traits that have allowed this group of mammals to effectively exploit the marine environment that is so hostile to humans. The content of this book is organised around common student questions, taking the undergraduate's point of view as the starting point. Each chapter provides a set of PowerPoint slides for instructors to use in teaching and students to use as study guides. New "Study Questions" and "Critical Thinking Points" conclude each chapter, which are each motivated by a "Driving Question" such as "How do mammals stay warm in a cold ocean?" or "How do mammals survive the crushing pressures of the deep sea?" Full-colour images and comprehensive, accessible content make this the definitive textbook for marine mammal physiology.
