The USSR has about 26 million ha of lakes, 7 million ha of reservoirs and 500 000 km of running waters on which inland fisheries can be practised. The principal characteristics of these water bodies are presented here, together with a survey of the most important species of fish, both indigenous and exotic, inhabiting the lakes and reservoirs. Details of inter-specific fish relationships are also discussed. Annual fish production from all inland waters, including aquaculture, had reached 988 000 tons by 1987. In addition anglers probably landed another 200 000 tons per year. Lake catches accounted for approximately 40-44% of the commercial catches, while the reservoir and riverine cataches contributed 28-34% and 23-30% respectively. Methods of fishery management are discussed, with emphasis on intensification practices. These include the establishment of highly productive fish farms and hatcheris, the conversion of reservoir shallows and small lakes into fish farms, the use of warmed effluent water from power stations, and the problems of introducing and acclimataing new species particularly Coregonidae and Chinese carps. The basic technical designs of fish passes and barriers are described, also details, design and operation of active and passive fishing equipment. Mention is made of legislation which governs fishing in the USSR, and some account is given of the development and current status of fisheries in the Aral and Caspian seas.

While almost every aspect of society-nature interactions can be treated as an environmental security issue, the threats to human societies originating from inadequate freshwater management constitute one of the most wi- spread and pressing problems. For thousands of years rivers and river valleys have been the cradle of human civilizations. Rivers have provided not only food and freshwater, but also shelter and means of transportation, and they are still an essential component in every national and regional economy. In turn, growing needs of human societies, accompanied by growing abilities, have caused significant river alterations and ecosystem changes that have resulted in river contamination, biodiversity loss and general riverine ecosystem degradation. The extinction of sturgeon species is one of the most eloquent examples of the negative and irreversible influence of human society on river e- systems. The sturgeon, sometimes called the “living fossil” or living “dinosaur” of the fish world, is known to have lived since the time of the dinosaurs, for at least 250 million years, and is currently on the verge of extinction solely due to anthropogenic impacts.

The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.

This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.

This report explores the potential for mitigating the impacts of climate change by improved management and protection of marine ecosystems and especially the vegetated coastal habitat, or blue carbon sinks. The objective of this report is to highlight the critical role of the oceans and ocean ecosystems in maintaining our climate and in assisting policy makers to mainstream an oceans agenda into national and international climate change initiatives. While emissions' reductions are currently at the centre of the climate change discussions, the critical role of the oceans and ocean ecosystems has been vastly overlooked.

The author shows that the way information and knowledge are made available can either limit or enlarge the ways people create and express themselves. He describes the range of legal and policy choices that confront.

Aquaculture is developing, expanding and intensifying in almost all regions of the world, except in sub-Saharan Africa. Although the sector appears to be capable of meeting the gap between future demand and supply for aquatic food, there are many constraints and challenges which must be addressed in order to at least maintain the present level of per capita consumption at the global level. Key issues are the need for enhanced enforcement of regulation and better governance of the sector, as well as greater producer participation in the decision-making and regulation process. This publication examines past trends in aquaculture development as well as the current global status, drawing on a number of national and regional reviews.
