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.

"Throughout the last century, specialisation and intensification were buzz words for farmers in the Western world. However, this approach has not resulted in sustainable development as evidenced by the fact that scientists now need to create technologies to reduce negative impacts. In this book we demonstrate that an alternative exists. Case studies from Bangladesh, Thailand, and Vietnam show that integration and diversification increase both farm productivity and farmers’ incomes. By adopting a participatory approach, farmers and scientists identified a range of technologies that strengthen the positive impacts of integrated aquaculture-agriculture systems for the environment.This book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters focus on nutrient cycling in such systems. Another chapter makes the case for breeding Nile tilapia for resource poor farmers and presents practical options to avoid the pitfalls that arise from natural tilapia mating in low-input ponds. The book contains chapters on livelihood and development aspects and ends with a general discussion completing the picture of the integrated aquaculture-agriculture systems. Overall it composes a review which addresses one of the key issues of the new century: how to sustainably produce food without compromising environmental integrity."

Loch Lomond has long held a special place in the hearts of all the people of Scotland not only for its historic significance but also for the beauty of its countryside. Less widely known is the ecological importance of the area. It is the largest stretch of freshwater in Britain and the only loch to be crossed by the Highland Boundary Fault, one of the country's most important geological features. The University of Glasgow has recognized the importance of this loch situated so near the main campus and has operated a field station on its shores since 1948. In the mid-1960s the field station was re-established at Rowardennan as an all-year-round facility with laboratory and living accommodation for resident research workers and visiting field courses. In 1992 a symposium was held to celebrate the 25th anniversary of the opening of the new station and this volume presents the proceedings of that symposium and gives the state of the present knowledge of Loch Lomond. After an introduction to Loch Lomond, the papers are divided into three sections. Section I: The physical and chemical environment of Loch Lomond and its catchment. Section II: The biology and ecology of Loch Lomond and its catchment, and Section III: Issues affecting Loch Lomond and its catchment.
