Book Description
Peacock Bass: Diversity, Ecology, and Conservation is a unique scientific reference that describes not only the diversity and natural history of the various peacock bass species (fish in the genus Cichla) but also their geographic distributions, evolutionary relationships, ecology, and economic importance. Peacock bass are the most popular sport fish pursued by recreational anglers in tropical freshwaters, and they support important fisheries in rivers and lakes in their native South America as well as other regions of the world where they have been introduced. The book is written in clear prose that allows any reader to appreciate key features of the morphology, population genetics, and reproductive biology of these colorful tropical freshwater fish. Each chapter begins with a vignette introducing an aspect of peacock bass taxonomy, ecology, or conservation based on a personal account from one of the authors. Also included are color photographs of peacock bass, their habitats, other tropical fishes, and the diverse wildlife encountered in rivers and forests of the Neotropics. Photographic guides and detailed descriptions of coloration patterns are provided for species identification, along with distribution maps and essential information related to fisheries management and the economic importance of peacock bass. Biologists interested in zoogeography and the ecological role peacock bass play as major predators in biodiverse rivers and lakes will find summaries of the latest information. Peacock bass have grown in popularity among aquarists, and the book provides basic information about captive care and environmental conditions in their natural habitats. This book is essential reading for biologists, fisheries managers, anglers, naturalists, and aquarists interested in these remarkable fish and the diverse tropical rivers they inhabit. Includes beautiful color photographs taken during field research Presents research vignettes to engage both scientists and laypersons Discusses feeding, cannibalism and effects on food webs Provides field maps and diagrams

Book Description
Marine, coastal and wetland habitats are threatened, through exploitation, and also by climate change, as ocean currents change course, sea levels rise, and rainfall patterns change. This book gathers papers on the biodiversity conservation of these increasingly threatened habitats. The papers provide a snapshot of the problems they face, and offer numerous examples which render this volume valuable to educators in marine, freshwater and wetlands ecology, conservation and ecological restoration.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book Description
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.

Book Description
Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.
