Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Biology and Ecology of Fishes Immerse yourself in the world of fish ecology with the newest edition of this essential introduction The study of fish ecology has traditionally proceeded along two tracks: the first is more basic, concerned with the anatomy, physiology and theoretical ecology of fish, and the second is more practical, concerning itself with fish populations, management, and habitats. Many fish researchers have come to view this distinction as artificial, and to develop a new study of fish that combines both tracks in a single holistic approach. It has never been more critical for introductory textbooks to represent this combined study in order to prepare the next generation of fish biologists and fishery scientists. Biology and Ecology of Fishes meets this need with a textbook that incorporates both biology and population management. Beginning with a general introduction to aquatic life and ecosystems, this book covers anatomical, environmental, and ethological topics to give a thoroughly rounded view of its subject, promising to serve as the fundamental introduction to multidisciplinary fish studies. Readers of the third edition of Biology and Ecology of Fishes will also find: Detailed coverage of subjects including growth and bioenergetics, feeding and predation, mortality and recruitment and more Increased attention to stressors of fish populations and communities New and revised chapters that introduce quantitative methods and present emerging issues facing fish populations and communities Biology and Ecology of Fishes is a useful overview for advanced undergraduate and graduate students studying fish ecology or fishery biology, as well as a reference for researchers and professionals in fish ecology, fish population management, and related fields.

The author spent much of 1989 and 1990 living within the Muscovite community and came into contact with people at all levels, from pimps to philosophers. He provides a portrait of a society which is struggling to survive the traumas and changes of the Gorbachev years. In some ways more medieval and Oriental than modern and Western, Moscow is a city in which tales of flying saucers and masonic conspiracies co-exist with endless queues, corruption, anti-semitism and a black market in guns. Durden-Smith also discovered in Moscow an intellectual passion and energy which puts most Western capitals to shame and which makes Moscow not only one of the most important, but also one of the most complex, contradictory and fascinating cities on earth.

This book introduces the ecology of fishes by describing the inter-relationships between fishes and the aquatic habitats they occupy. It can be read in complementary ways. A sequential reading, chapter by chapter, covers the main themes of ecology, including habitat use, species interactions, migration, feeding, population dynamics and reproduction in realtion to the major habitats occupied by fishes. An alternative reading selects a particular sort of habitat, such as rivers, and by skipping from chapter to chapter, builds up a picture of the ecology of fishes living in that habitat. "Fish Ecology" is written for students in marine ecology, freshwater ecology, fish biology, fisheries ecology and aquaculture.

Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 0.05%. These environments differ from marine conditions in many ways, the most obvious being the difference in levels of salinity. To survive fresh water, the fish need a range of physiological adaptations. 41.24% of all known species of fish are found in fresh water. A fish is defined as an aquatic or marine animal with vertebrae. All fish have vertebra, except sharks and rays that have cartilage. Cartilage is more flexible than bone, but strong enough to support the body. They usually possess gills in the adult stage and have limbs in the form of fins. Fishes also include the jawless vertebrates such as the lamprey and hagfish; and the shark, ray, chimaera, lungfish, and bony fishes. The bony fishes are the most common. A bony fish has jaws that are well developed, formed by true bone rather than cartilage. Fish are very different in appearance, size and shape. This all depends on the environment that it lives in. Fish are part of the ecosystem entering the flux of energy at different levels of the food chain. This book introduces the ecology of fishes by describing the inter-relationships between fishes and the aquatic habitats they occupy. Sequential reading, chapter by chapter, covers the main themes of ecology, including habitat use, species interactions, migration, feeding, population dynamics and reproduction in relation to the major habitats occupied by fishes.

Today, fishing is the main extractive utilize of wildlife in the world. In 2010, the annual capture, uniting both wild capture and aquaculture, was 149 million tons (FAO, 2012). As regards 94% of all freshwater fisheries occur in developing countries (FAO, 2007). They give food and a livelihood for millions of the world's poorest people, and also give to the overall economic security by earnings of export commodity trade, tourism and recreation. Even though freshwater fishes have a long history of human-induced introduction, recent globalization has enhanced worldwide introduction events even more, and those introduced fish species are now apparent to be a major risk to ecosystems. Over the last two decades, numerous studies have been published on introduced fish species; however, it has been demanding for researchers to understand the magnitude of the impact and the fundamental mechanism of offensive. Recently, new perspectives in understanding invasive freshwater fish biology have been presented in a number of studies, which can be largely attributed to advances in analytical techniques and also to a growing need for proactive analysis in management strategies. This book brings together the state of the art information contributed by renowned authors and field experts on varied aspects of fish and fisheries biology including the age, growth, length weight, fecundity, reproductive behavior feeding habits, and necessary environment for each freshwater species. The content covers on new ecological perspectives, the need for research, and/or management implications with emphasis on technological advances, including biochemical taxonomy and stock identification, genetics and genetic manipulation, physiology, functional morphology, behavior, ecology, fisheries assessment, development, exploitation and conservation. This guide is intended to act as a valuable information resource for advanced graduate students, environmental and fisheries professionals, naturalists, and educators on the use of fishes as biological indicators.
