Marked pollution events can also occur following shipping incidents (Carls, Marty & Hose 2002), or chronically from low‐level continuous waste disposal, particularly involving persistent or physiologically active compounds (Matthiessen & Law 2002). Fisheries Exploitation by Albatross Quantified With Lipid Analysis. The role of industrial fisheries and oceanographic change in the decline of North Sea black‐legged kittiwakes. Current Issues in Aquaculture: Lessons from Malaysia. Use the link below to share a full-text version of this article with your friends and colleagues. In setting the scene for this ‘special profile’, this introduction overviews the context in which major papers on the applied ecology of aquatic systems are emerging, and it identifies scope for further contributions. Two ocean currents meet in the Grand Banks, the cold Labrador Current and the warm Gulf Stream. Symptoms of excessive exploitation also affect fishes in freshwaters, where fishery resources in general are considered important but under‐valued (Pauly et al. Interspecific effects of artificially propagated fish: an additional conservation risk for salmon, Life after death in Lake Erie: nutrient controls drive fish species richness, rehabilitation, Testing large‐scale hypotheses using surveys: the effects of land use on the habitats, invertebrates and birds of Himalayan rivers, Contaminants and their effects on estuarine and coastal organisms in the United Kingdom in the late twentieth century, Movements and foraging areas of grey seals in the North Sea, Upstream movement of residual hatchery steelhead into areas containing bull trout and cutthroat trout, Eutrophication, fisheries, and consumer‐resource dynamics in marine pelagic ecosystems, Introductions and extinction of fish in the African Great‐Lakes, Effects of habitat fragmentation by damming on the persistence of stream‐dwelling charr populations, Ecosystem recovery in restored headwater streams: the role of enhanced leaf retention, Effect of aquaculture on world fish supplies, Favorable foraging locations for young Atlantic salmon: application to habitat and population restoration, On the decline of Pacific salmon and speculative links to salmon farming in British Columbia, Coral reef disturbance and resilience in a human‐dominated environment, Global scale patterns of fish species richness in rivers, Three challenges for the science of river conservation, Applied issues with predators and predation: editor's introduction, Restoration in applied ecology: editor's introduction, Towards sustainability in world fisheries, Long‐term indirect effects of mechanical cockle‐dredging on intertidal bivalve stocks in the Wadden Sea, Long‐term changes in the trophic level of the Celtic Sea fish community and fish market price distribution, Trophic cascades in benthic marine ecosystems: lessons for fisheries and protected‐area management, Fisheries managed to rebuild ecosystems? Prediction to allow adaptive management in anticipation of future global change is still in need of considerable development (Hall 2002; Jurado‐Molina & Livingston 2002). Although the five papers that follow are apparently disparate – the benefit of aquatic reserves, river restoration for fish, the accumulation of contaminants, interactions with predators, and the fitness of salmonids from nurseries – they illustrate significant contributions from our authors on themes whose diversity matches today's most topical aquatic management issues. By Meryl J. Williams. 2000; Hogg et al. The international trade in fish products in this sample year, of $US 55 billion (FAO 2002), was greater than the individual gross domestic product of over 70% of the world's nations. 2001). Issues contain features, essays, AFS news, current events, book reviews, editorials, letters, job notices, chapter activities, and a calendar of events. 2002; Van Parijs, Smith & Corkeron 2002). Previously widespread problems from organic effluents and some industrial discharges have been largely controlled, at least in economically richer countries, although some substances continue to cause concern (Hall 2002; Mason 2002). In freshwaters, flow regulation and obstruction by dams, fragmentation, catchment management, pollution, habitat alterations, exotic fish introductions and nursery‐reared fish … Current Problems in the Management of Marine Fisheries. The management problems that result include predatory, competitive or deplacement effects on indigenous fishes (Levin et al. 5. Spearfishing Regulation Benefits Artisanal Fisheries: The ReGS Indicator and Its Application to a Multiple-Use Mediterranean Marine Protected Area. Increasingly, research efforts are turning to methods of controlling or eradicating exotic fish species, but the difficulties are substantial. Further substantial implications will arise with implementation of the European Union directive on integrated river basin management with its strong emphasis on ecological quality (2000/60/EC). Watson, J.W., et al., Fishing methods to reduce sea turtle mortality associated with pelagic longlines. The impacts of climate change interact with the existing problems of overfishing and habitat destruction, driven largely by excess fishing fleets, coastal development and market expansion. This paper provides an overview of the intersection between oceans and fisheries issues, and trade policy. Power et al. Interaction between bottlenose dolphin (Tursiops truncatus) and trammel nets in the Archipelago de La Maddalena, Italy. Downloadable (with restrictions)! The principal ethical issues in fisheries relate broadly to human and ecosystem well-being (see Box, below). Many fisheries will be in decline as a result of climate change, ocean acidification, overfishing and destruction of marine ecosystems, noted Nereus Program researchers. This is emphasised particularly by the growing legislative drive in Europe and elsewhere to return systems to ‘good ecological status’ (2000/60/EC). These attempts have not, by and large, successfully met the challenge of balancing current and future use of fisheries. All rights reserved. Their work reveals only negligible beneficial effects from physical manipulations alone, hinting at the potential importance of other limits on fish recovery such as connectivity, water quality or ecological attributes in the target species, all of which should ideally be addressed in aquatic restoration. In providing a badly needed systematic and replicated study of rehabilitation, Pretty et al. But this need is now being highlighted more than ever as aquatic systems are simultaneously viewed not only as the source of major goods and services, but also as systems whose use depends on long‐term viability, integrity, sustainability and conservation (Pitcher 2001; Jackson et al. Fisheries of the United States compiles key statistics into a snapshot of fishing’s importance to the nation. This overview outlines the current context in which papers on the applied ecology of fish and fisheries are emerging, and it identifies scope for further contributions. Many have distributions that reflect the richness and productivity of fish distributions – exactly the features sought also for commercial fishing activity. Any future fisheries management arrangements within the UK must continue to respect the current terms of devolution. This section provides a short overview of some of the most important ones: poverty; the right to food; and overfishing and ecosystem degradation. Inadequate government capacity and cooperation to manage, regulate, and control fisheries and fisheries trade, especially in developing nations and on the high seas, are key factors contributing to the current problems in oceanic fisheries. In this paper we identify the critical issues which Caribbean Community (CARICOM) countries must address in defining their approach to fisheries governance. 2008. Bulletin of Environmental Contamination and Toxicology. 2. In this issue of the Journal of Applied Ecology, Sundbom et al. The English Channel stock of Sepia officinalis: Modelling variability in abundance and impact of the fishery. Finally, as in all the Journal's ‘special profiles’, the papers collected and reviewed here illustrate the substantial contributions being made by ecologists in addressing real and present environmental problems (Ormerod et al. var switchTo5x=true; The last of these is still a minority approach, with surface waters considerably under‐represented in reserve networks by comparison with terrestrial ecosystems. Additionally, with over 25 000 known species, the biodiversity and ecological roles of fishes are being increasingly recognised in aquatic conservation, ecosystem management, restoration and aquatic environmental regulation. Power of monitoring programmes to detect decline and recovery of rare and vulnerable fish. Variation in the abundance of sandeels Ammodytes marinus off southeast Scotland: an evaluation of area-closure fisheries management and stock abundance assessment methods. // ]]>//
