Value can be added to projects for restoring the aesthetic appeal of modified waterways at very little extra cost if the needs of the living components of the system are taken into account. This manual was prepared by the European Inland Fisheries Advisory Commission (EIFAC) to provide guidelines and techniques for the rehabilitation of rivers for fish. It is intended for the use of fisheries managers, fisheries and wildlife biologists, land and water use planners, and civil engineers working on projects involving the protection and rehabilitation of inland running waters. While the primary orientation of the manual is towards rivers of the temperate zone, the techniques described can be applied to the restoration of rivers of similar dimensions in other climatic areas.

The best and most expensive caviar uses eggs from sturgeons caught in the Caspian Sea. But eggs from many other fish species have been used to develop products imitating original caviar. By utilizing processes appropriate for each kind of fish, it is possible to make a similar, though imitation, product. This publication presents an overview of the production of lumpfish eggs as a model for developing fish caviar. It describes fishing methods, preservation and storage of the eggs, as well as details on the caviar production process itself to obtain the final product. Production and marketing statistics demonstrate the extent of the global lumpfish caviar business. The publication draws heavily on source material from Iceland.

Many rivers, lakes and other inland waters have been modified and degraded by human activities. Rehabilitation of degraded systems and mitigation of impacts of ongoing stresses are needed to preserve ecosystem services and fisheries and are of a high priority if the aquatic biodiversity of inland waters is to be conserved. A number of technical solutions for rehabilitation and mitigation are available to restore habitat diversity, provide for environmental flows and ensure longitudinal and lateral connectivity within such systems. It is recommended that such methods are applied on a basin-wide scale but it is recognized that more restricted sections of waterbodies may have to be targeted. Planning for rehabilitation projects needs to be carefully conceived with clear objectives of the rehabilitation and selection methods to be used. Selecting appropriate methods for any particular waterbody depends on local, social and economic conditions and priorities. Land tenure, local laws and the interests of other local stakeholders in the resource also need to be incorporated into rehabilitation plans. In international rivers and lakes, rehabilitation plans may need negotiation and cooperation by all riparian states. After execution, rehabilitation projects should be carefully monitored in order to meet the objectives.

The fish habitat restoration procedures presented in this guide provide the technical basis for a suite of integrated restorative measures to accelerate natural recovery processes in forested watersheds impacted by past practices that would otherwise require decades to recover naturally. An introductory section contains chapters on planning fish habitat rehabilitation, watershed geomorphology and fish habitat, salmonid biostandards for estimating production benefits of rehabilitation techniques, and screening criteria for restoration projects. Sections on the application of rehabilitation techniques cover such topics as fish access and spawning sites, stream banks, off-channel habitat, using large woody debris, log-jam habitats, juvenile salmonid habitat, mainstem holding and rearing habitat, nutrient replacement, habitats in channelized or uniform streams, augmenting streamflows, and managing beaver habitat for salmonids. Includes glossary.

The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly. Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

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.

The review presents the strong business case for inland food fisheries in developing countries to be either a co-benefit, or very often the main benefit, of ecosystem restoration. In view of the current state of inland water aquatic habitats the potential for restoration is high. Realizing this potential requires concerted action to overcome current challenges, foremost of which is the invisibility of inland fisheries in many policy arenas as well as technical and scientific fora. The drivers of ecosystem degradation, ecosystem services valuation frameworks and the main technical tools for implementing interventions are presented. Experiences in developed countries dominate the literature but are not necessarily applicable to developing country inland food fisheries. Local communities that have high dependency on inland fisheries and live in close association with inland water fisheries habitats not only provide much higher fisheries values but a management asset that is unavailable in developed countries and the mainstay of many successful restoration programmes. Ten case studies, representing effective restoration of food fisheries from local to basin scale are used to illustrate what can be achieved. The prospects of inland fisheries benefiting from, or contributing to, the UN Decade on Ecosystem Restoration (2021–2030) are good but upscaling the existing progress will require increased and sustained efforts to mainstream the values of inland fisheries including their co-benefits for biodiversity conservation.
