There is a growing recognition of the need to conserve biodiversity that has been conceptualised in the Convention of Biological Diversity. Maintenance of fish species richness is particularly important, because habitat degradation in inland waters continues to accelerate on a global scale. Here we develop empirical models for predicting fish species(More)
O of the world’s fisheries is the subject of much recent concern (FAO 2002, Pauly et al. 2002, Hilborn et al. 2003). Although the global production of fish and fishery products continues to grow, the harvest from capture fisheries has stagnated over the last decade. Today numerous fish stocks and species have declined since their historical peaks, and some(More)
The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community(More)
The past decade has seen increased international recognition of the importance of the services provided by natural ecosystems. It is unclear however whether such international awareness will lead to improved environmental management in many regions. We explore this issue by examining the specific case of fish migration and dams on the Mekong river. We(More)
A model is developed which describes the way in which the fish populations of African rivers and their fisheries are influenced by the different types of flood Regime. Ichthyomass and fish catch are dependent on both the extent of flooding during high water and the amount of water remaining in the system during the dry season. The relative number and(More)
At present, inland fisheries are not often a national or regional governance priority and as a result, inland capture fisheries are undervalued and largely overlooked. As such they are threatened in both developing and developed countries. Indeed, due to lack of reliable data, inland fisheries have never been part of any high profile global fisheries(More)
O environmental degradation, and redistribution of surface water have placed great stress on inland fisheries throughout the world. Human activities usually shift the balance among fish species, causing the extirpation of many indigenous species and the dominance of a reduced set of often introduced fish species. The result has been a massive reshaping of(More)
In view of the dearth of books on tropical river fisheries, it is a pleasure to be able to review two books dealing with the fish and fisheries of that largest of rivers, the Amazon. With two books having such similar titles and subject matter, it is tempting to make direct comparisons between them. However, the diverse backgrounds of the two authors have(More)
