Book (series)Review of the State of the World Fishery Resources: Inland Fisheries 2011
Also available in:
No results found.The fishery statistics reported to FAO by countries and maintained in the FishStat database are analysed for trends in quantity and composition of catches from 1950 to 2009. Catches have been increasing at a steady rate throughout the period. Fish from inland water capture fisheries are an important source of animal protein, especially in landlocked countries and for populations riparian to lakes and rivers. Finfish contribute about 90 percent of the catch together with some crustaceans and molluscs. The accuracy of reporting of catches by taxonomic group has improved with time and more groups are being reported in 2009 than in 1950. At the same time, the percentage of catches assigned to the generic “freshwater fishes NEI” category has declined. Trends in catches and taxonomic groups are analysed for subcontinental regions under a more general continental heading. The regions are divided mainly by geography, although in some cases economic and political consideration s are used. Catches in the various regions of Africa, Asia and South and Central America have risen steadily over the period of the review, although there are local exceptions to the general trend. There is clear evidence that such increases are real in some individual fisheries, but generally the increases are attributed to improvements in reporting, whereby catches that were already there but previously ignored are now being incorporated into the reports. Catches in North America, an d most of Europe, have declined in the same period, which is attributed to shifts in economic conditions that make fishing not longer financially viable, and a greater public demand for recreational fishing. Catches from eastern Europe and the Russian Federation declined from a maximum in the 1980s, but have shown some signs of recovery in the last decade. In general, the world’s inland fisheries still appear viable although environmental pressures, such as damming, water abstraction a nd overexploitation, pose a potential threat to the maintenance of present levels of reproduction and recruitment, and hence, ultimately catch. -

Also available in:
No results found.The objective of this review is to present a broad view of the state of inland capture fisheries as of 2001. Status and trends, are reported along with coverage of selected sections on the impacts of dams on fisheries, fisheries in rice-based ecosystems, database on African water resources, indices of human development and environmental sustainability, and new approaches to improving inland fishery information. -
Book (series)Review of the state of world fishery resources: inland fisheries 1999
Also available in:
No results found.The purpose of this review is to present a broad view of the state of inland capture fisheries. The review is organised in three main parts. The first part is an overview of inland capture. Overall, the trend is for an annual average increase in inland capture of about 138 000 t. The nominal inland capture amounted to about 7.7 million t in 1997. Actual inland capture is considerably greater than the amounts reported to FAO. The factor is at least two overall, but may be as high as thr ee in some instances. There is an urgent need for better data on inland fisheries that can be interpreted in both economic and ecological terms. Although the cost of improving inland fishery data collection may be high, failure to fully account for inland capture also is costly in terms of lessened, or lost, opportunities to increase food security and other economic and social benefits from inland fishery resources. The second part deals with trends in capture organised by continenta l regions, sub-regions and countries for the period 1984 to 1997. Asia produces a disproportionately large share of the global inland capture in relation to its continental land area and the water surface available there. The 14-year trends are for increases in inland capture in Asia, Africa and Latin America and for decreases in the Former USSR Region, North America and Europe while Oceania is stable. The third part sets out major issues, of which the environment is the salient conc ern, and future directions of inland fisheries, mainly towards increased uses of enhancements to increase outputs. Enhancements are characterised on a global basis according to type, species and geographical distribution. Rehabilitation and mitigation of inland systems are highlighted as is the importance of recreational inland fisheries.
