Book Description
What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

Book Description
Sustainable Fish Production and Processing is a unique resource that bridges the gap between academia and industry by analyzing new, state-of-the-art fish production, processing and waste management. The book explores general valorization methods, focusing on the extraction of high added-value compounds and their reutilization in different fields of the food and nutraceuticals industry. Sections take a comprehensive approach to understanding the most recent advances in the field, while also analyzing the potentiality and sustainability of already commercialized processes and products. This resource could be utilized as a handbook for anyone dealing with sustainability issues within the fish industry.Emphasis of fish production is given to food security issues, large marine ecosystems, aquaculture genomics, epigenetics and breeding, proteomics for quality and safety in fishery products, post-harvest practices in small scale fisheries, and lifecycle impact of industrial aquaculture systems. Emphasis of fish processing and by-products is given to industrial thawing of fish blocks, sources and functional properties of fish protein hydrolysates, recovery technologies and applications, potential biomedical applications, ready-to-eat products, fish waste for bacterial protease production, fish waste for feeding as well as lipid extraction from fish processing for biofuels. - Covers recent advances in the field of fish production and processing over the last decade, following sustainability principles - Discusses the advantages and disadvantages of relevant processes from various perspectives to improve sustainability - Offers practical success stories and solutions to ensure the sustainable management of fish processing by-products

Book Description
The percid fishes (or perch family) comprise many species including the perch, pikeperch, yellow perch, walleye and the darters. These species are of great ecological and economic importance, being important components of the freshwater ecosystem and recreational and commercial fisheries. Percid Fishes covers aspects such as systematics, morphology, biology, ecology, diseases and parasites and the economic importance of percid fisheries. Special emphasis is placed within the book on the complex relationship between this family of fishes and their environment and how they respond to perturbations, especially those induced by humans. The author, John Craig who has a great deal of experience working on these fishes in many of the countries in which they occur, has drawn together an extremely important book which provides a unique, comprehensive and indispensable review of this most significant group of fish.

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
Lakes of Africa: Microbial Diversity and Sustainability examines microbial ecosystems in African lakes, including the history and formation of African lakes. The book describes how environmental stressors—including seasonal variations, climate change, and anthropogenic activities—affect microbial ecosystem dynamics in African lakes and the microbial responses to these stressors. The book explores and evaluates extremophiles in African lakes, including industrial biotechnology applications. The book highlights challenges facing microbial ecology in African lakes, as well as the design of models for solving these problems and predicting the future of lake microbial ecosystem sustainability. - Includes unique case studies on both African lakes and brine lakes, providing real life examples of the topics discussed - Provides a foundational background to the topic - Presents definitions throughout, whenever a new term is introduced, for a seamless reading experience and background information

Book Description
A considerable quantity of data and information were collected on many aspects of the systems of the three reservoirs, including hydrological, biophysical and limnological features, primary production, and fish and fisheries data. This information was condensed and synthesized with the aim of providing a baseline against which the ecological changes that have taken place since impoundment can be described and analysed. Efforts are made to explain changes in fish catch in relation to climatic variations, ecological succession and fishing effort. The review shows that biological data and information are generally available. However, as is also common elsewhere, all three cases suffer from the general tendency to isolate and compartmentalize research into separate disciplines.
