Mensen hebben nog nooit zoveel vis gegeten en meer mensen dan ooit zijn werkzaam in de visserij of aanverwante sectoren. Vis voorziet meer dan drie miljard mensen in minstens 15 procent van hun inname van dierlijke eiwitten. Visvangst en aquacultuur zorgen bovendien voor bestaansmiddelen voor naar naar schatting 540 miljoen mensen.
Visserijproducten blijven ook de meest verhandelde voedingsmiddelen, met een waarde van 102 miljard dollar in 2008, negen procent meer dan het jaar voordien. De wereldwijde productie van vis en visproducten steeg van 140 miljoen ton in 2007 naar 145 miljoen ton in 2009, zo staat te lezen in het pas gepubliceerde State of the World's Fisheries and Aquaculture. Met een groei van zeven procent per jaar, wordt steeds meer vis gewonnen via aquacultuur.
Slechter nieuws is er wat de overexploitatie van visbestanden betreft. Die blijkt niet gedaald en is naar schatting zelfs lichtjes ernstiger dan in 2006. Ongeveer 32 procent van de wereldwijde visbestanden zou overbevist zijn en moet daar dringend van herstellen, stelt het FAO-rapport. Anderzijds wordt 15 procent van de stocks weinig (3%) of matig (12%) bevist zodat de FAO meent dat de visvangst in die gebieden kan worden opgedreven.
Om de overbevissing tegen te gaan, onderzoekt het rapport de inspanningen die van overheidswege geleverd worden om de controle op de sector te vergroten. Het gaat om handelsmaatregelen die illegale visproducten weren uit de internationale handel, maar ook om maatregelen die gericht zijn tegen illegale, niet vergunde visvangst. Alleen al de kost van dat laatste zou oplopen van 10 tot 24 milard dollar per jaar.
"De groeiende visconsumptie toont de nood aan voor een duurzaam management van de visbestanden", stelt de FAO. Het rapport beveelt een geïntegreerde aanpak van het ecosysteem aan. Daarbij worden sociale aspecten afgewogen tegen de toestand van de visbestanden en de omgeving. Het rapport verwijst als 'good practice' naar het beleid inzake aquacultuur dat in Zuidoost-Azië gevoerd wordt, waar vis een fundamenteel deel van het dieet van de bevolking is.
Fish consumption reaches all-time high
BeantwoordenVerwijderenNo improvement in level of global fish stocks – FAO report reviews latest data and trends
Rome, 31 January 2011 - The contribution of fish to global diets has reached a record of almost 17 kg per person on average, supplying over three billion people with at least 15 percent of their average animal protein intake. This increase is due mainly to the ever-growing production of aquaculture which is set to overtake capture fisheries as a source of food fish, according to the State of the World's Fisheries and Aquaculture, released today. The report also stressed that the status of global fish stocks has not improved.
Overall, fisheries and aquaculture support the livelihoods of an estimated 540 million people, or eight percent of the world population. People have never eaten as much fish and more people than ever are employed in or depend on the sector.
Fish products continue to be the most-traded of food commodities, worth a record $102 billion in 2008, up nine percent from 2007.
The overall percentage of overexploited, depleted or recovering fish stocks in the world's oceans has not dropped and is estimated to be slightly higher than in 2006. About 32 percent of world fish stocks are estimated to be overexploited, depleted or recovering and need to be urgently rebuilt, the report says.
On the other end of the scale, 15 percent of the stock groups monitored by FAO were estimated to be underexploited (three percent) or moderately exploited (12 percent) and therefore able to produce more than their current catches.
"That there has been no improvement in the status of stocks is a matter of great concern," said senior FAO fisheries expert Richard Grainger, one of the report's editors. "The percentage of overexploitation needs to go down although at least we seem to be reaching a plateau."
Tighter control
The report examines the growing legal efforts to enforce tighter controls on the fisheries sector, for example, through trade measures and against illegal, unreported and unregulated fishing.
The trade measures are meant to block entry of such fish and fish products from international trade in an effort to better manage the entire fisheries sector and reduce levels of overexploitation. A recent study estimates the cost of illegal and unreported fishing alone at $10-23.5 billion per year.
The report also notes increasing debate about a proposed global record of fishing vessels, which ideally would assign a unique vessel identifier to each vessel that would remain constant regardless of ownership or flag changes over time. Such transparency would make it easier to police vessels engaged in illegal fishing activities.
The increasing demand for fish highlights the need for the sustainable management of aquatic resources. The report recommends an ecosystem approach to fisheries, which is an integrated approach for balancing societal objectives with the state of the fishery and its natural and human environment.
Snapshot of the sector
BeantwoordenVerwijderenTotal world production of fish and fish products rose from 140 million tonnes in 2007 to 145 million tonnes in 2009, according to the FAO report. Much of the fish now comes from aquaculture, which is growing at the rate of almost seven percent a year.
The report held up aquaculture policies in Southeast Asia — where fish is a fundamental part of people's diets — as a good example of balanced management. The report praised continuously improving government interventions built on comparative advantages and economic incentives that lead to growth, food security and better living standards.
The report contains a special chapter on inland fisheries. Inland fisheries are often overlooked by policymakers and irrigation and hydroelectric schemes are at times planned without regard for the impact on inland fishers' livelihoods. However, inland fisheries supports 61 million people worldwide.
"Fish is a good quality and high protein food and the sector contributes in an important way to world food security," said Grainger.
