Pheromones are chemical cues that pass between members of the same species that convey specific, adaptive information. These cues, and related chemicals whose function are less well defined, are especially important to fishes because of their aquatic environments and complex behaviors. Pheromones are also of increasing interest in both basic and applied aspects of fish biology because they can be used to manipulate fish behavior and may explain phenomena such as fishery collapse. Fish Pheromones and Related Cues provides a timely synthesis of this growing body of research in freshwater and marine species and explores everything from how these chemical signals evolved, are produced, released and then processed, and finally to potential applications in fish culture and conservation. Fish Pheromones and Related Cues opens with a useful overview on the theory of chemical communication and definitions. Chapters then progress by examining the biological importance of pheromones in inter- and intra-species communication, the role these chemical cues play in a variety biological functions from reproduction to predation, and then how they evolved and are detected and recognized by fish nervous systems. Final chapters provide valuable insight into how pheromones can be measured, how pheromonal disruption can explain effects of environmental pollution, and lastly how they pheromones are being applied in real-world efforts to culture fish species and to conserve our wild populations and control invasive species. With far-reaching economic, evolutionary and ecological implications, Fish Pheromones and Related Cues will be an essential volume for anyone working in the fields of chemical communication, fish biology, fisheries science, aquatic conservation, ecology, invasive species control, and aquaculture
This book concerns how estrogens are synthesized in the brain and their two modes of action on behavior: a slow process involving gene transcription and a faster action at the cell membrane. The significance of the regulation and distribution of the estrogen synthesizing enzyme aromatase in the brain is also highlighted.
This book addresses the growing needs in deciphering the biological processes associated with fish reproduction, in view of the growth of aquaculture and the dwindling natural stocks of commercially important fish. It presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. With this view in mind, the book includes chapters on oocyte development (oogenesis), hormonal regulation and hormone receptors, formation of the egg envelopes, growth, accumulation of nutrients and maternal transcripts, maturation, hydration, ovulation and fertilization. A special emphasis is placed on using state-of-the-art tools including electron microscopy for discerning the ultra-structure of the follicle and genomic/proteomic tools to fully understand biological basis of fish reproduction. Studies on promoting oocyte maturation, ovulation and spawning in farmed fish and preservation of fish oocytes at low temperatures are also included. The book will appeal to University lecturers, students, research scientists and those associated with culture of fish in freshwater or marine aquaculture.
Revised throughout, the 5th Edition presents a complete and up-to-date review and analysis of all aspects of endocrinology, diabetes, and bone metabolism. Readers will also find state-of-the-art information on genetics, proteinomics, and hormone signaling, and coverage of the field{19}s hottest topics in nearly 20 new chapters. Joined by an international team of leading experts (many new to this edition) Drs. Jameson and DeGroot provide guidance that integrates the basic science of endocrinology with clinical medicine and the practical management of endocrine disorders with a clinical focus emphasizes diagnosis and therapy. It organizes information into basic and clinical sections that makes reference quick and easy, and provides tables designed to summarize and organize information, presenting over 1,400 illustrations that clarify complex concepts.
`The book is important for those involved in aquaculture and those wishing to learn more about the effects of non-infectious disorders and the mechanisms of response within fish and is thoroughly recommended.' Journal of Fish Diseases --
