|  Marine capture fisheries and marine aquaculture together produce about just below 100 million tonnes of fish (in round weight equivalent), or about 80 % of the total quantity of fish produced by the inland and marine aquatic ecosystems. Ocean fisheries provide directly and indirectly livelihoods to a large proportion of the 140 million people who, globally, are estimated to depend on fisheries and aquaculture for a living. Recreational fisheries contribute also substantially to the global economy, tourism development, and quality of life. Fish and fish products provide a variable but significant proportion of humanity's animal protein needs. For many of the world's most vulnerable people living on coastal zones or islands it is a particularly important and often vital source of protein and of many micronutrients necessary for a healthy life. | | |  The intrinsic value of marine life and the socio-economic importance of the fishery sector underpin the necessity for governments, to establish effective management systems in their exclusive economic zones and in the high seas. The available information on the state of the fishery resources indicate that, in 2000, about 50% of marine fish stocks are close to their maximum biological production level (or maximum sustainable yield), about 25% are overfished, and about 25% could possibly sustain higher exploitation rates. However, those stocks being fished at their maximum level of production could rapidly become overfished if fishing pressure is not effectively controlled. Historical data indicate that the proportion of stocks being overfished has increased significantly since the early seventies, underlining the need for an improvement in fisheries governance. Additional stress on the fisheries production system is added by pollution and environmental degradation from non-fisheries developments, including land-based ones, with long-lasting and possibly irreversible consequences for fisheries.The contribution of aquaculture and coastal aquaculture is increasing rapidly, filling the gap between supply and demand of fishery products. This development meets with problems related inter alia to water use rights ; pollution; diseases; invasive species; and modification of wild genetic pools. An excellent review of the present global status of aquaculture is available courtesy of Dr. Albert G.J. Tacon of the Hawaiian Institute of Marine Biology. A very large PDF file (10 MB) with pictures and a smaller (2 MB) PDF file without pictures, but with complete graphics, are available. | | |  Careful and thoughtful improvement in the governance of fishing and aquaculture, and its integration with other sectors'management (e.g. in the coastal areas) could bring about greater reliability of supply, improved economic viability and the generation of increased benefits for fishers and for society as a whole. Failure to establish effective governance in fisheries and in coastal areas could result in a further deterioration in food security, particularly for the most vulnerable people in the developing world; increasing impoverishment of fishers; and destabilization of social structures in remote coastal areas. New forms of governance are being tested, including various forms of fishing rights as well as precautionary and ecosystem-based approaches. | | | | |
 | | | | | Fishery Statistics: Reliability and policy implications
by FAO, FAO 01 February 2002 | |
| | 12 February 2002 A recent scientific article in Nature indicated that China?s marine capture fishery production for 1995-1999 has been overstated in Chinese statistics submitted to and published by FAO. The paper states that a consequence of this is that global marine capture fishery production - excluding Peruvian anchoveta - has probably been declining since 1988 rather than remaining fairly constant as indicated by the statistics. According to the authors from the University of British Columbia (UBC), this would have led to understating the degradation of world fisheries and wrong policy and investment decisions. The issue has been subsequently taken up in a number of newspapers and web media including The Economist. While usefully drawing attention of the wider public on the importance of reliable statistics for fisheries management and monitoring, the articles also reflected a number of misconceptions about: (1) FAO?s understanding of Chinese statistics; (2) FAO?s role in global fisheries statistics; and (3) the possible consequences of an over-estimate of China?s fisheries production on global fisheries management advice, policy and contribution to food security. | |
