This book provides the first synthesis of quantitative information on brown trout ecology. By comparing the brown trout to closely related species such as the Atlantic salmon, the Pacific salmon, and the rainbow trout, the author illuminates key issues regarding animal ecology in general. Topics include the global success of the brown trout, long-term case studies of the dynamics of one brown trout population, ecological differences between brown trout populations, natural selection and genetic differences between brown trout, and the mechanisms responsible for population regulation in juvenile trout. The book ends with conclusions that can be drawn about brown trout ecology, a discussion of how those conclusions can aid in conservation and management, and an effort to identify areas in need of further research. The book emphasizes the development, testing, and use of realistic mathematical models that have proven so effective in the preservation of valuable species. Students and professional ecologists, fish biologists, and fisheries managers will welcome this incisive resource.

This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This new edition: contains a new chapter on Plankton in the Classroom has greatly expanded coverage of coastal and marine phytoplankton explains the role of plankton in aquatic ecosystems and its usefulness as a water quality indicator updates and details best practice in methodology for plankton sampling and monitoring programs brings together widely-scattered information on freshwater and coastal phytoplankton and zooplankton and provides a list of up-to-date references. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.

The farming of the freshwater prawn "Macrobrachium rosenbergii" has developed rapidly during recent years. Advances in techniques, and the huge expansion of world demand for this species, continue to stimulate the growth of a multi-million dollar industry.

This landmark publication is a compendium of information on every aspect of the farming of "M. rosenbergii." A comprehensive review of the status of freshwater prawn farming research, development and commercial practice, the book is intended to stimulate further advances in the knowledge and understanding of this important field.

An extremely well-known and internationally-respected team of contributing authors have written cutting edge chapters covering all major aspects of the subject. Coverage includes biology, hatchery and grow-out culture systems, feeds and feeding, up-to-date information on the status of freshwater prawn farming around the world, post-harvest handling and processing, markets, and economics and business management. Further chapters are devoted to the culture of other prawn species, prawn capture fisheries and the sustainability of freshwater prawn culture. Contributions to the book have been brought together and edited by Michael New and Wagner Valenti, themselves widely known for their work in this area.

The comprehensive information in "Freshwater Prawn Culture" will give an important commercial edge to anyone involved in the culture and trade of freshwater prawns. Readership should include prawn farm personnel, business managers and researchers, and invertebrate, freshwater and crustacean biologists. Copies of the book should be available on the shelves of all libraries in research establishments and universities where aquaculture and fisheries are studied and taught.
