Reviews advances in the understanding of the biology, ecology and management of the Atlantic salmon throughout its geographical range, and examines the effects on salmon of afforestation, pollution, acid rain, water abstraction and changing agricultural methods. The rapid escalation of salmon farming with its impact on wild stocks is analyzed as is the increasing threat of over-exploitation on both the open seas and in home waters.

The cichlid fishes are an important group, being widely used in scientific research and as popular fish with aquarists. This group contains mainly small species which adjust quickly to captivity, exhibiting a readiness to breed and long periods of parental care for the young. This books comprehensive volume describes the current knowledge on the behaviour and ecology of the cichlid fishes.

Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold Antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air breathing in catfish and...

This book covers in detail the development and use of the electric sense in fishes. Contents include coverage of taxonomy of the species involved, electric organs and electroreception, hormones and behaviour and the role of other sensory systems in conjunction with the electric sense. The book will be of great value to fish biologists, physiologists, evolutionary scientists, animal behaviourists and aquatic scientists.

The Alantic salmon (Salmo salar) is a fish of major biological interest and economic importance. Recent years have witnessed major advances in the understanding of the many facets of the biology, ecology and management of this fish. The author, Dr Derek Mills, covers all major aspects of the atlantic salmon throughout its geographical range in the northern hemisphere.

Provides a thorough introduction to the biology of fishes, covering basic diversity, biology and physiology. Detailed coverage of environmental aspects relating to fish biology is a key feature of this book which will be of great use to students and individuals in fish biology, fisheries, aquaculture and environmental sciences.

The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options', ' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a...

This dictionary lists the English, German, French and Italian names of amphibians occurring in Europe, North America, Canada, Central and Southern Africa, Australia and New Zealand, the Indian Subcontinent, South East Asia, Virgin Islands and Puerto Rico and the islands of the West Indies. It lists 5,367 scientific names of orders, families, genera, species and subspecies. The relevant order and family are shown for each term. The taxonomy is that used by the different authors of the sources.

This second volume in the series covers such topics as DNA fingerprinting of fishes, the cytochromes P450 in fish, the molecular biology of bacterial fish diseases, and new insights into the origins of the diversity and distribution of fish antifreeze proteins. The book will be of great value to fisheries scientists, animal biochemists, physiologists and endocrinologists, and aquaculturists. It will provide researchers and students alike with a pertinent information source from theoretical and experimental angles.

The hard clam, Mercenaria mercenaria, is an important commercial, recreational and ecological inhabitant of coastal bays along the east and gulf coasts of the United States. This title represents the first state of the art summary of existing knowledge of the hard clam by experts in various disciplines.

Containing a compendium of literature on the hard clam, comprehensive chapters on various aspects of its biology as well as summaries of knowledge including the gray literature on this economically important species, this volume represents a comprehensive source of biological information...

The definitive guide to the study of fish

In this second edition of Ichthyology, readers will find a comprehensive resource. Starting with the basic definition of what fish are, where they live, and how they live, this in-depth text provides an ordered approach covering this branch of science in its entirety. Readers will discover the major groups of fishes, learn about basic fish anatomy, be introduced to issues of nutrition and growth, gain an understanding of fish locomotion, and much more. For those interested in the advancing in the field, the book also discusses...

This guide to maintaining seawater fish in aquariums describes water chemistry, technology and the biological and physical processes of the aquarium ecosystem. Additionally, it presents fish physiology, nutrition, diseases and health maintenance. It is designed as a practical book, providing usable methods and specific protocols for keeping marine fish, with the emphasis on professional approaches for public aquariums.

Presents aquatic chemistry in a way that is truly useful to those with diverse backgrounds in the sciences. Major improvements to this edition include a complete rewrite of the first three background chapters making them user-friendly. There is less emphasis on mathematics and concepts are illustrated with actual examples to facilitate understanding.

Engagingly written, with both learning and humor, Fish bridges the gap between purely pictorial books and scholarly texts, and provides a succinct summary of fish biology and conservation for students and fish enthusiasts.

This guide is the only complete reference to the sharks, rays, and chimaeras found in California's waters from the intertidal zone to 500 miles offshore.
Species accounts give information on habitat and range, natural history, interactions with humans, nomenclature, and further references
68 beautiful color illustrations show each shark, ray, and chimaera; accompanying line drawings highlight differences in teeth, underside of the head, and egg cases
Includes information on the California marine environment, ecology and conservation, and shark biology"

This book gives a concise account of the physiology and form of the fish circulatory system. The emphasis is primarily on function, but details of structure have been included. Following a revision of ideas on hemodynamics, attention is focused on the heart as the primary pump in the fish circulatory system. The fine structure and the electrical and ionic events of cardiac myocytes are described and the major events of the cardiac cycle are outlined. The structure of the peripheral vessels then follow and attention is devoted to the circulation in certain special areas such as the gills, the...

This important title encompasses features of genetic processes in complexly organised population systems of salmonids, one of the most commercially valuable families of fish worldwide. Translated from the original work in Russian, the authors have taken the opportunity to update and revise the work, much of it appearing in the English language for the first time.

Covering such important concepts as optimal gene diversity and the unfavourable influence of fishery and hatchery reproduction on the genetic structure of salmon populations, the authors have drawn together a huge wealth of...

Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource.
