How much of the worlds fish is managed sustainably? On the y-axis we have the share of organisms that are removed or killed by a single pass of a trawl over the seabed. Some of us might picture a lone fisherman with a wooden fishing rod. (1998). Learn more about how Statista can support your business. UNEP-WCMC and IUCN (2021), Protected Planet: The World Database on Protected Areas (WDPA) and World Database on Other Effective Area-based Conservation Measures (WD-OECM) [Online], September 2021, Cambridge, UK: UNEP-WCMC and IUCN. Fish stocks and fishing intensity for each region on one chart, Fish stocks and fishing intensity for each type on one chart. But if you pick farmed salmon you are almost guaranteed that it will be relatively low-carbon. NOAA Fisheries' Marine Recreational Information Program is the state-regional-federal partnership that develops, improves, and implements a national network of recreational fishing surveys to estimate total recreational catch. The world has set long-term targets on the extent of marine protected areas. This data is sourced fromPauly D., Zeller D., Palomares M.L.D. Ask local experts about the state of fish stocks and most have a similar take: they are in poor condition.17. It doesnt tell us about what fish we might want to buy or avoid. Discards are not reported. Thats part of the explanation for why feed inputs in the 1960s, 70s, 80s and 90s were higher than aquaculture production. In the second bar we see global aquaculture production. We are happy to help. If it is partly fed by wild fish, perhaps more fish farms means more pressure on wild fish stocks? Please consult our full legal disclaimer. The data are collected using internationally agreed concepts and definitions developed by the Coordinating Working Party on Fishery Statistics, comprising Eurostat and several other international organisations with responsibilities in fishery statistics. We produce around 112 million tonnes of farmed seafood a year. But with massive improvements in efficiency, it is now a net producer of seafood. 84% of this was used for direct human consumption. The UN Fisheries Division did an independent assessment of discards and found a similar result.39 It estimated that annual discards (averaged over 2010 to 2014) was around 9.1 million tonnes. Except that for land-based animals, farming is many thousand years old while it was very uncommon for seafood until just over 50 years ago. The other two-thirds, though, are sustainable and not in decline. But this does not tell us how much fish was sourced sustainably. This gives us a static view of global fisheries, but how has this been changing over time? It has been growing rapidly in China and India since the 1980s. For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. Furthermore, in September, the Secretary of Agriculture made $530 million available through the Seafood Trade Relief Program to support fishermen and industries impacted by retaliatory tariffs from foreign governments. That is, essentially, the amount of wild fish there. In our related article we look at which are managing well, and which are doing poorly. Although these rates have stabilized or even declined in the last few years. Farmed salmon only ranges from 4.1 to 6.2 kg CO2e: a 50% difference between the minimum and maximum. The report provides landings totals for both domestic recreational and commercial fisheries by species and allows us to track important indicators such as annual seafood consumption and the productivity of top fishing ports. The U.S. fishing and seafood sector generated more than $200 billion in annual sales and supported 1.7 million jobs in recent years. Scientific surveys have periodically monitored stocks in the Gulf of Thailand for decades. Golden, C. D., Koehn, J. This doesnt really inform us about what type of fish to eat. They published their results in 2009 in the journal Science.11 They concluded that although around two-thirds of assessed fisheries are below the biomass that would give us the maximum sustainable yield, catch is now within or even below sustainable levels in 7 of the 10 studied ecosystems. Again, this is measured relative to the intensity at the maximum sustainable yield. It shows us first, in red, the observations in the Worm et al. In the chart we see the spread of greenhouse gas emissions among the different types of seafood. Restaurant closures, social distancing protocols, and other safety measures also contributed to losses in other sectors of the seafood economy.

But the fact that discards have been falling means that we can do something about it. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). Often its a species of fish in a given location. Only landings the fish brought back to land are recorded in most databases, such as those of the UN fisheries. Profit from the additional features of your individual account. In blue we see the more recent data from Worm and Hilborns collaboration of fish stock (abundance) data. Thankfully thats not the case.The extent of trawling varies a lot from region-to-region. In the chart we see the breakdown of global fish catch in 2017.33 The world caught around 109 million tonnes of fish. Therefore much of our work on fish on Our World in Data will explore these concepts, and explain what the research and data tells us about fish stocks, catch and the sustainability of fishing across the world. Several years might seem like a long time, but its actually pretty fast for an ecosystem to recover. This is a key concept in fishery research and industry. Sampled fish are taken to assess the age and population growth rate of the population. on August 25, 2022, Stay informed of all the latest regional news around NOAA Fisheries, U.S. A review of the data from 2000-2017 found that 791 commercial fishermen died while fishing in the United States. Whats also important to note is that the same areas are often trawled again and again.27 What this means is that its not a different 5 million km2 thats trawled every year. Many of the effective solutions to reduce discards relies on effective monitoring and enforcement of fishery policies. Stock A is sustainable and were catching 80 tonnes of fish per year. Scientists use acoustics and other methods to monitor and estimate the abundance of fish at any given time. This gear is used across the world, but there are some general patterns to where certain methods are more widely used. Lets say we have two fish stocks. Fish stocks tend to be a lagging indicator to fishing intensity. Fishery Technology, 55: 118.Wienbeck, H., Herrmann, B., Moderhak, W. & Stepputtis, D. 2011. But this will come at the cost of catch and income for communities that rely on it. Fishers might also have strict quota restrictions on how much they can bring back each day. So a ratio of 2 means you need two fish equivalents of fishmeal and oil to be able to produce one fish in return. Ricard, D., Minto, C., Jensen, O.P. In 2006, the fisheries researcher Boris Worm and his colleagues published a paper in Science on the trends in biodiversity loss in the worlds oceans.10 The year 2048 and prospects for global collapse, was only mentioned once, and featured in the conclusion of the article: Our data highlight the societal consequences of an ongoing erosion of diversity that appears to be accelerating on a global scale. Charter operations were completely shut down in most coastal states beginning in mid-March, with phased re-openings starting in May. The State of World Fisheries and Aquaculture 2020. The impact of trawling really depends on the type of method and gear thats used. Lets then turn towards the health of fish across the regions we do have good assessments for. When we look at the breakdown we also see that the amount that is allocated to fishmeal and oil (animal feed) has also not changed much since 1990. A few groups are not faring so well. The chart here show the distribution of wild fish catch by country. If you get greedy and catch more than this, then you deplete populations for future generations. How did they reach this conclusion? ICES Journal of Marine Science. The New York Times ran the headline Study Sees Global Collapse of Fish Species, and coverage snowballed from there.

This decline is seen even more clearly in this chart, which shows the amount of wild fish used as animal feed (in blue) and aquaculture production (in red).35 As we will see later, in its infancy, the aquaculture industry was inefficient. Scientists can do this through a combination of sonar acoustic methods (which lets them build a picture of the number and density of fish) and fishing (which lets them identify specific species in the ecosystem). Help us do this work by making a donation. Our recreational fisheries statistics help scientists and managers assess and maintain sustainable fish stocks. Internet Explorer lacks support for the features of this website. Although exploitation rates varied year-to-year, this generally increased through the 1980s, 1990s and early 2000s. Abundance and biology tell us how many fish we would otherwise expect to be there before we remove any. Nature, 1-6. If we cant or dont want to eliminate it completely, there are still things we can do to limit its impacts. As of 2021, 7.7% of the total ocean is protected. Science, 314(5800), 787-790. Many have questioned whether aquaculture is really the solution that it seems. But the big difference comes from the spread of emissions: wild-caught can range anywhere from 1.7 to 17 kg CO2e. This is why I dont find the comparison between dredging and rainforest clearing to be a particularly helpful one. However, growing concern about the depletion of wild fish stocks has led to a significant reduction in recent decades, to allow populations to recover. This is shown in the map here. If we cut down the Amazon rainforest, it is decades if not centuries before it gets back to its previous state (if it gets there at all).

If theyre over the limit, they will have to throw some fish back. As these fish tend to also have a low carbon and land footprint, farmed fish can be a low-impact source of protein. Here were looking at the median across all of the assessed studies.21 These impacts are shown per kilogram of edible weight. A 20-year retrospective review of global aquaculture. But often they will throw these unwanted fish back into the water. Many are in trouble and are at risk of collapse if we do not take action. Disturbance of the seabed by mobile fishing gear: a comparison to forest clearcutting. U.S. seafood exports declined 18 percent in value in the January to June period, when compared to the past five years. This is often measured in terms of fish stocks. Licenses: All visualizations, data, and articles produced by Our World in Data are open access under the Creative Commons BY license. Hawaii is estimated to have lost 99 percentof charter trips between April and July. Nature communications,1(1), 1-6. The animals they throw back are called discards. There are several methods we use to better-understand the health of fish stocks. . This 1998 paper, for example, compares trawling to Amazonian forest clearcutting.Watling, L., & Norse, E. A. Today, this ratio for the most common species carp, tilapia, and catfishes, shown at the top is incredibly low. (Statista) #11. For example, they might be used to set catch limits at levels that are sustainable given the dynamics and health of the fish population. In some countries it accounts for a much larger share: more than one-third in the Maldives; one-fifth in Japan, Iceland and Cambodia; and 14% in Hong Kong. This is incompatible with restoring populations to their historical levels, because we cant do that and catch lots of fish at the same time. Many types have a lower carbon footprint than chicken (those that are higher are around 20-30% higher). In some cases, they eliminate this contact completely. The width of the bar shows us how variable this can be: it tells us what the largest and smallest impact can be for each species. Sustainability in action. In the coming months and years, scientists and economists will work to obtain a more complete picture of COVID-19s impact on U.S. seafood and the Blue Economy. Our World in Data is free and accessible for everyone. But with wild fish populations we have another dimension to consider: whats happening to their population numbers. Both Albacore tunas and Yellowfin tunas moved from Near threatened to Least concern. The figureheads on both sides of the debate Ray Hilborn and Boris Worm both featured on a debate on National Public Radio.
