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
The existing literature on limnology and fisheries of Indian reservoirs has been reviewed by covering more than 100 reservoirs located in various parts of the country. An assessment of environment-mediated production functions of reservoirs has been attempted. Since the ecosystem processes in reservoirs belonging to different geo-climatic regions exhibit wide variations depending on meteorological, morphometric and hydro-edaphic features of the impoundments, an effort has been made to gauge the influence of these abiotic variables on the production dynamics. Authentic information on water areas under different categories of reservoirs has been collected and interpreted in respect of all the Indian States. An attempt has also been made to resolve the anomalies pertaining to classification and nomenclature to the extent possible. Various fisheries management norms followed in the reservoirs of the country including the selection of species for stocking, stocking rate and introduction of exotic species have been reviewed. Indian reservoirs have been stocked with the Indo-Gangetic carps for many decades and the impact of this stocking has been assessed in terms of fish production and the indigenous faunistic diversity.

Book Description
Small pelagic fish species found in lakes and introduced to reservoirs dominate by volume and contribute some of the most important inland fisheries in Africa with steadily increasing catches and additional potential. This circular reviews the status and importance of the pelagic fish and fisheries, together with small fish in general, for sustainable and healthy livelihoods in Africa. It reviews the biology and biological production of the most important pelagic species in lakes and reservoirs as well as the impacts of environmental and climatic variation on the stocks of these species. It examines and discuss the various capture techniques together with potential of improvements in the fisheries and associated processing and national and regional trade within Africa. The knowledge generated by the circular will be useful for policy makers and development practitioners to design and implement more effective policies, strategies and programs that will contribute to reducing the food insecurity and conflicts that currently affect the people in sub-Saharan Africa.

Book Description
Community Based Fisheries Management: A Global Perspective unravels the different aspects of CBFM from different continents and countries. At a time when the population is significantly increasing, with resources decreasing, this resource is directly relevant to helping communities understand and improve fishery production management in a sustainably way. Sections explore various scientific literature on the impact of community-based fishing, participatory management of water bodies, methodologies for studies on community-based fisheries management, and interviews of workers working on community-based fisheries. This information will be most useful to fish farmers, aquaculturists, fish and fishery scientists, research scholars and anyone else interested in this field. Based on 30 years of scientific research, this resource emphasizes the need for the management of resources through the involvement of the local community while also providing a framework for participatory collaboration. Provides methods of data collection and statistical tools for data analysis Presents the basic procedures necessary to conduct a CBFM study Includes information on the impacts of climate change and economics

Book Description
Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development. Published with IWMI.

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.
