Six species of sturgeons are native to the Danube River Basin. The need for conservation action is urgent, given that recent observations in the Lower Danube indicate that all sturgeon populations are near extinction. Due to the high commercial value of sturgeon products, in particular caviar, the pressure from proaching and illegal trade remains intense. These species will not survive unless fishing practices are greatly addressed, and both migration routes and habitats for all life-cycle stages are protected. Through national action and international co-ordination, this action plan aims to secure viable populations of all Danube sturgeon species by sustainable management and restoration of their natural habitats and migratory corridors
Inland waterway management is complex and faces unique challenges as inland waterways have a variety of users. The mixture and overlap of local, regional, national and at times international regulations exacerbate the problem of managing inland waterways. In this context, the regional conference ‘River habitat restoration for inland fisheries in the Danube River basin and adjacent Black Sea areas’ was held on 13-15 November 2018 in Bucharest, Romania. This event was organised by the FAO Regional office for Europe and Central Asia in partnership with the International Organisation for the Development of Fisheries and Aquaculture in Europe (EUROFISH) and EIFAAC and hosted by the Ministry of Agriculture and Rural Development and the Ministry of Waters and Forests of Romania. This event offered a unique opportunity for stakeholders to share their experience of the issues affecting the sustainability of the Danube river and Black Sea regions. Over 100 attendees from local community level fisherman and farmers to academics, and national and EU level representatives interacted with to 27 invited speakers. Each speaker focused on one of four session subjects ‘Valuing Inland Fisheries Resources’, ‘Conservation and Management’, ‘Regulatory Framework’ and ‘Shared Country Experiences’. A round table discussion concluded the conference, with all participants invited to express their thoughts and discuss the issues affecting sustainability and inland fisheries in the Danube river basin and the Black Sea. The key findings from this concluding discussion have been complied into a list of conference recommendations included in this publication.
Watersheds, supplying crucial ecosystem services to humans, seem to be a logical territorial unit to integrate societal benefits and environmental needs in order to evaluate the sustainability of natural resource use patterns. Based on this belief the book is an attempt to initiate a comprehensive environmental security assessment in the basin of the Azov Sea, shared by Russia and Ukraine. Though the region provides a variety of essential services and plays a strategic role in national and international development plans, it has been excluded from most regional environmental discussions. At the same time there is an alarming degradation rate of basin freshwater ecosystems that has occurred due to overutilization of certain prioritized services (e.g. transportation). The collapse of neglected services (e.g. fishery and freshwater supply) poses serious threats to the national economies as well as the local population, and to mitigate these threats priority in water management should be given to securing sustainability of the regional freshwater ecosystems. In addition to the review of the current status of Azov ecosystem services, the authors analyze likely future availability and challenges. The relevant experience derived from basin management of the Black Sea and other similar basins is also discussed.
Based on the bestselling book, Rivers of North America, this new guide stands as the only primary source of complete and comparative baseline data on the biological and hydrological characteristics of more than 180 of the highest profile rivers in Europe. With numerous full-color photographs and maps, Rivers of Europe includes conservation information on current patterns of river use and the extent to which human society has exploited and impacted them. Rivers of Europe provides the information ecologists and conservation managers need to better assess their management and meet the EU legislative good governance targets. - Coverage on more than 180 European rivers - Summarizes biological, ecological and biodiversity characteristics - Provides conservation managers with information to resolve conflicts between recreational use of rivers, their use as a water supply, and the need to conserve natural habitats - Data on river hydrology (maximum , minimum and average flow rates), seasonal variation in water flow - Numerous full-color photographs - Information on the underlying geology and its affect on river behaviour
The second-longest European river after the Volga, the Danube is one of the world’s most important rivers in terms of its geographical and historical significance. In recent history, it has served as a major international waterway and numerous cities, including four capitals, have been founded on its banks. The 2826km-long Danube has a watershed measuring 801,093 km2 that is now shared between 19 countries, from its source in the Black Forest to the Black Sea, into which it pumps an average of 827 km3 of water a year. This book describes and explains key landscape values interactions (geographical, cultural and natural heritage). It also identifies the threats and various types of human impact affecting this system in all the countries of the Danube River Basin, based on the investigations and perspectives of a team of experienced naturalists, and in the context of the early 21st century, in which the human-nature relationship is still far from balanced. These studies demonstrate how biodiversity, conservation and ecological studies can help us successfully promote mutual cooperation and combine our efforts to address problems as a responsible continent.
A fishery is an area with an associated fish or aquatic population which is harvested for its value (commercial, recreational, subsistence). It can be saltwater or freshwater, wild or farmed. Examples are the salmon fishery of Alaska, the cod fishery off the Lofoten islands or the tuna fishery of the Eastern Pacific. Most fisheries are marine, rather than freshwater; most marine fisheries are based near the coast. This is not only because harvesting from relatively shallow waters is easier than in the open ocean, but also because fish are much more abundant near the coastal shelf, due to coastal upwelling and the abundance of nutrients available there. However, productive wild fisheries also exist in open oceans, particularly by seamounts, and inland in lakes and rivers. Most fisheries are wild fisheries, but increasingly fisheries are farmed. Farming can occur in coastal areas, such as with oyster farms, but more typically occur inland, in lakes, ponds, tanks and other enclosures. This book is devoted to the management, economics and perspectives of fisheries.
