The case of the UK, Portugal and Spain are shown in the chart. Contrast that with those at the bottom of the table: Indians and South Africans consume less than 10 kilograms. Are you interested in testing our business solutions? In other words: while many stocks are still in a poor state, things are improving across many ecosystems. The European Mediterranean is not doing well. This mirrors the assessment of fisheries by the UN FAO. In 2018, capture fisheries produced a whopping 94.4 million tons of fish. When we cut down primary rainforest we are locking ourselves into a recovery period of many decades. Its the number of fish multiplied by their mass. Lets first understand the amount of wild fish that is used as feed. Al Roker with Danielle Blacklock, Director of NOAA's Office of Aquaculture. 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). These assessments have become the bedrock of fisheries management. In 2017 this ratio was 0.28: we get three fish back from one fish used as inputs.37 This improvement came from efficiency gains, as well as a switch to other plant-based feed blends. On the x-axis we have the depth into the ocean sediment that the trawl reaches. Also, the recreational charter/for-hire fishing industry was completely shut down in the spring with some phased reopenings in the early summer. You need at least a Starter Account to use this feature. The decline that Worm et al. Other surveys of trawling efforts across the region show similar declines. You can see these rates by region here. Is the global fishing industry sustainable? Again, we should be careful to not mistake this as the total feed conversion ratio (FCR). We just saw examples of this across Europe and Japan. While losses vary by sector, by region and by industry, data and information from this report may help businesses and communities assess losses and inform long-term recovery and resilience strategies. Back in 2009, it covered 166 of the worlds fish stocks which accounted for around 20% of global fish catch.15 Today it covers over 1,200 fish stocks, which is more than 50% of global catch. 90% was brought ashore and used for human food or animal feed. Hawaii sportfishing tournaments have been similarly impacted. In other words: if you view fish as a resource you probably want fish populations to be less than half the size of pre-fishing size. (2017). One option is therefore to ban specific types of gear rather than banning the practice completely. Impacts of biodiversity loss on ocean ecosystem services. Fish stocks are healthy across most of these regions. Stock B is unsustainable and were catching 20 tonnes from it. 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. In our Fish Stocks Data Explorer we present the key metrics on assessed fish stocks from the RAM Legacy Database.18 This provides a high-resolution breakdown of specific fish stocks across the world. This relationship is not as strong for seafood. 93% come from industrial fishing. We often hear that tuna are being overfished to extinction. Others lag behind, but theres no reason to think that they could not do the same. Hiddink, J. G., Jennings, S., & Kaiser, M. J. The new analysis contains, The report notes that some U.S. industry losses may be offset by the infusion of emergency federal relief funding. We will cover that in much more detail in a follow-up article. Get in touch with us. Trawling does not have the same impacts as cutting down a primary rainforest. Maximally sustainably fished: this has sometimes been termed fully fished or fully exploited in the past. Gillnets and longlines account for much less of global fish catch. Credit: NOAA Fisheries, NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION, Report a Stranded or Injured Marine Animal, Climate, Ecosystems & Fisheries Initiative. The health of tuna populations has been a concern for decades. Statistics show there were 2,098 Scottish-registered and . But this is one that simply wont die it has been repeated so many times that many believe it to be true. Internet Explorer lacks support for the features of this website. Stock assessments are used by fisheries across the world to understand the health of fish populations, and implement strategies to manage their fisheries. The COVID-19 pandemic has created an exceptional crisis for fishing communities and the fishing industry as a whole. For billions of people across the world, fish is an important source of nutrition. Hilborn, R., Amoroso, R. O., Anderson, C. M., Baum, J. K., Branch, T. A., Costello, C., & Ye, Y. In the chart we see the same metric as before fish stocks measured by biomass across different types. Nature, 405(6790), 1017-1024. Farmed salmon, trout, carp and catfish are also good choices. Five centuries of cod catches in Eastern Canada. There are also large differences in how variable emissions can be. When fishers go out to catch fish, it would be great if they only caught the fish that they needed. Statistics On the x-axis we have fishing pressure; as we move towards the right we catch a larger proportion of the fish stock each year. In the visualizations we see the change in aquaculture and capture fishery production from 1960 onwards. Over the last decade, there has been some variability but overfishing has hovered around one-third globally. This increased to 14 million tonnes in 1989. If aquaculture was putting pressure on fish production, its not obvious from the total catch. First as the global distribution, shown on the map. From the chart we see that most are above one: the maximum sustainable yield. Fish and Fisheries, 6(2): 134155. & Suuronen, P. 2003. As we see in the chart, aquaculture production increased by 250% between 2000 and 2015. Seaspiracy is far from the first source to repeat this claim: Google empty oceans by 2048 and you will find hundreds of thousands of results. Modifying fishing gear to achieve ecosystem objectives. Some countries in the world eat close to 100 kilograms of seafood per person each year. In 2023, the market is forecast to decline by 0.9 percent to 11.4 billion U.S. dollars. Many more stocks have not been assessed and these are likely to be in regions where monitoring is poor; and illegal catch is poorly regulated. Are you interested in testing our business solutions? Nearly all of the growth in seafood production in recent decades has come from aquaculture; wild fish catch has changed very little. The other school of thought views fish as a resource. Get the best reports to understand your industry, Outdoor recreation market in the United Kingdom (UK). Whats the story here? For example, the doors on otter trawls are very destructive; newer designs now limit the amount of impact these doors have with the seafloor. Youre not going to generate the same unwanted catch using a fishing rod as you are from bottom trawling dragging a large net along the seafloor. Grocery prices finally dipped in March, falling for the first time since September 2020, according to data released Wednesday by the Bureau of Labor Statistics. Both figures are up from 2016, when vessels landed 5 million metric tons, earning fishers an estimated $11.3 billion dockside. More than double that of chicken. Globally, the share of fish stocks which are overexploited meaning we catch them faster than they can reproduce to sustain population levels has more than doubled since the 1980s and this means that current levels of wild fish catch are unsustainable. Its not the case that we put 12.6 million tonnes of feed in, and magically get 112 million tonnes of fish back. Again, we should be clear that the most effective way to reduce the impact of your diet is to eat less animal-sourced products overall. All the software and code that we write is open source and made available via GitHub under the permissive MIT license. Ocean Recovery: A sustainable future for global fisheries?. This balance can change from season-to-season, or even month-to-month as environmental factors change and affect the dynamics of the ecosystem. There was a strong start to the year, with a 3 percent increase in commercial fish landings revenue in January and February. Not all aquaculture species are fed from animal sources, but many are. When we view fish through different lenses, these debates dont get very far. They are carried out using the ABC method This is the collection of three key metrics: A = Abundance. The health of the worlds fish populations is one of our biggest concerns when it comes to the sustainability of fishing. Fisheries management impacts on target species status. So a ratio of 2 means you need two fish equivalents of fishmeal and oil to be able to produce one fish in return. Compared to other meats, seafood has a low environmental footprint when it comes to greenhouse gas emissions, land use, and nutrient pollution we looked at this in a related article. One of the biggest conflicts I see is not actually about technical discussions of how much fish we catch, or whether populations are increasing or decreasing, but a larger ethical conflict in how we view fish. This data is sourced from the Sea Around Us database published by Pauly, Zeller and Palomares, available at: http://www.seaaroundus.org/. Roberts, C. M.The Unnatural History of the Sea(Island Press, 2007). Historical records from the UK give us further understanding of the long-term trend in fisheries. It covered over 1690 fish farms, and 1000 records from fisheries. Show sources information Sometimes there are claims that seem so far-fetched that its hard to imagine they need to be addressed. For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. Rather than relying on reported data on fish catch, the scientists set out to build a database on global fish stocks. In Ghana, for example, purse seine recently became the most common form of catch. This is a positive sign. But it has not changed much since the 1990s. Fisheries that are not carrying out these assessments will struggle to maintain this balance. This growth in aquaculture has played an important role in increasing global seafood production without sacrificing fish stocks. Then 30% by 2037, and 50% by 2044. By the end of second quarter 2020, 78 percent of aquaculture, aquaponics, and allied businesses reported COVID-19 impacts with 74 percent experiencing lost sales. Fears that a growing aquaculture industry would put more and more pressure on wild fish stocks has not come true. 84% of this was used for direct human consumption. This project relies on multiple sources but primarily the FishStat database published by the Food and Agriculture Organization of the United Nations. Lets take a closer look at the impacts of specific types of seafood. Costello, M. J., Cheung, A., & De Hauwere, N. (2010). On the trade front, international markets were negatively affected by disruptions in harvesting, processing and shipping. Find your information in our database containing over 20,000 reports, most popular outdoor recreational activities in the United States, freshwater fishing attracted almost 43 million participants, women accounted for 36 percent of all fishing participants in the United States, fishing as a hobby is more prevalent with older generations, average number of people per fishing trip. Large-scale practices are almost non-existent. Say the word fishing and very different images come to mind. Compared to 2019, this is a slight increase in the quantity of sea fish landed and a. Theres one key metric that we need to understand the efficiency of fish feed: the FIFO ratio. Overall we see that seafood has a relatively low environmental impact among animal protein sources. Released 2021-05-27. The trend looks worse for those in the Indian Ocean. Particularly since the late 1980s, annual production has increased rapidly. How much of the worlds fish is caught sustainably? The statistic shows the gross value of production of fisheries and aquaculture in China between 2011 and 2021. A value below one is not good: fish stocks as lower than wed like and while we might catch more fish in the short-term we will miss out in the longer-term. Marine protected areas (MPAs) are areas of ocean which includes the water column and seafloor that have been reserved by law or other effective means to protect part or all of the enclosed environment. Overall, aquaculture is an important solution to meet growing demand for seafood. How much of the worlds ocean is protected today? In 1974, just 10% were overexploited. Reducing discards is a good thing. The fisheries sector is a direct source of livelihoods for more than 20 million fishers and fish farmers; contributes INR 1.75 lakh crore annually to the gross value added to India's economy; and is a major export earner, with fish being one of the most important agricultural commodities to be exported from India. This is reflected in the fact that the Black Sea is very overfished. These matter because they depend on what fish we want to catch; affect how much fish we can catch (and ultimately, the amount of fish we have to eat; and the income fishers get); and what the ecological impacts are. Employment in harvesting processing and aquaculture is found across the country except for Alberta, Nunavut and the Yukon. We see that much more of the worlds national waters are protected than international ones. This is because fish tend to be more efficient than chickens in converting feed into meat: that means they need less feed per kilogram. Our comparison on greenhouse gas emissions includes both wild-caught seafood, and seafood from fish farms. Lets first look at the question of how much of the seafloor is affected by trawling. That is, essentially, the amount of wild fish there. But, since the millennium, better management of fisheries and reduced overfishing means that many of these stocks are recovering. In this realm, our end goal is often to restore wild animal populations to as close to their pre-human levels as possible. (Statista) #2. Effect of netting direction and number of meshes around on size selection in the codend for Baltic cod (Gadus morhua). But dredging sometimes referred to as bottom trawling has the largest negative impact. Its possible to get all of the protein we need from plant sources. American Sportfishing Association These results look at the impacts on-farm and off-farm, up to the farmgate. Unfortunately there are key regions where we have very little data. Small-scale fisheries contribute very little. 633. When a fish stock is at its maximum sustainable yield its around half of its original, virgin biomass.9 This level can vary between fish populations but is typically in the range of 37% to 50% of its pre-fishing levels. IBISWorld. How much fish do people across the world eat, and how much of our nutrition does it provide? 2009. The other two-thirds, though, are sustainable and not in decline. The remaining 16% was turned into fishmeal and oils to use as animal feed. To their credit, these two sides soon joined forces, working collaboratively to get a much larger and rigorous overview of the status of the worlds fish populations. But we also want to know how seafood compares to other protein foods. We cannot take endless numbers of wild fish from our oceans, so if we want more fish, were going to have to produce our own. Whether a fish stock is doing well or not is mainly determined by its fishing intensity: what fraction of the population is being caught each year. But with wild fish populations we have another dimension to consider: whats happening to their population numbers. The distinction between farmed fish and wild catch is similar to the difference between raising livestock rather than hunting wild animals. Importantly, this metric treats each fish stock as being equal, regardless of how big each stock is. Proceedings of the National Academy of Sciences, 114(31), 8301-8306. In a new study published in Nature, Jessica Gephart and colleagues conducted a meta-analysis of the impacts of fish and seafood across multiple environmental metrics.19 To do this they combined life-cycle analysis data from studies of wild-caught and farmed seafood products. The number of fishers across Europe has more than halved since its peak in 2000 [you can view these trends by region using the blue Change region button]. 2020 (a paper we covered here) as a sign that biomass and fishing pressure are both moving in the right direction in assessed stocks. American Sportfishing Association | All Rights Reserved. This suggests the reduction in catch has been driven by a decline in the availability of bottom-living fish, rather than changes in fishing effort. The U.S. fishing and seafood sector generated more than $200 billion in annual sales and supported 1.7 million jobs in recent years. Around 11% of fish catch is used as feed for aquaculture today. To better serve retailers and the trade, ASA conducted a survey of tackle retailers in January 2022 inquiring about their January-December 2021 business experience. Science, 325(5940), 578-585. Proceedings of the National Academy of Sciences, 114(1), 178-183. "Market size of the fishing industry in the United States from 2013 to 2022 with a forecast for 2023 (in billion U.S. We can see these two schools of thought emerge in the typical diagram of sustainable fishing. Others are trawled over and over. For the best experience, please use a modern browser such as Chrome, Firefox, or Edge. Fish and Fisheries, 19(1), 30-39. NOAA Fisheries estimates that in the Southeast, charter revenues relative to the preceding 3-year period fell 72 percent in March through April due to local and state COVID-related closures and protocols. It might even be lower than farmed salmon. In the chart here we see the per capita protein intake from different sources across the world.Globally, 7% of total protein intake comes from seafood.7. UK sea fisheries annual statistics reports MMO experimental statistics reports Data The publications include information on: the structure and activity of the UK fishing industry landings. In a paper published in Nature, Enric Sala and colleagues estimate that around 5 million square kilometers (km2) of seabed is trawled each year.24 In the chart below Ive put this into context of the global seabed area as a whole. Wild-caught fish such as salmon or tuna can have a lower or higher footprint depending on where and how its caught. Prez Roda, M.A. C = Catch. In addition, the European Commission banned bottom trawling in deep waters those below 800m in depth in 2016. That matters for where you source wild-caught fish from: sourcing from European or American fisheries might be a safer choice if you want to ensure they are sustainable. This is available here: http://www.fao.org/fishery/statistics/software/fishstatj/en. The share that is overexploited has been relatively stable in recent decades. They use very tiny amounts of fishmeal as inputs. Environmental impact can mean very different things: greenhouse gas emissions, land use, water use or chemical pollution. Maintaining sustainable fish stocks relies on us understanding how quickly fish populations regenerate, and balancing this with how much fish we catch. Pelagic (midwater) trawling accounts for an additional 10%. How much of the worlds ocean is protected? One innovation has helped to alleviate some of the pressure on wild fish catch: aquaculture, the practice of fish and seafood farming. Rebuilding global fisheries. It shows a more stable trend in collapse stocks over the last few decades. projected in their earlier paper has not come true. Please create an employee account to be able to mark statistics as favorites. Across most of the main fish groups tunas, shrimp, cod, and perch stocks are at or above one the sweet-spot where we catch as many fish as possible while keeping populations stable. Researchers gather data on how much catch is discarded when different types of fishing gear are used. Research suggests that where stocks are healthy, a net only passes over the same spot once in a period of 3 to 10 years. Like any type of animal farming, we need to feed them. In the chart we see global fish catch since 1950.34 It is broken down by whether it is used for direct human consumption, animal feed, or other uses (which are mainly industrial uses of oils). If you catch too little then youre sacrificing food and income for the current generation. In 2018, this was 8.6 million tonnes of animals. 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. Due to varying update cycles, statistics can display more up-to-date Its not the case that more and more aquaculture puts more and more pressure on wild fish. Clicking on the following button will update the content below. If you choose wild-caught salmon you could be picking a low-carbon, or a high-carbon protein source. Trawling rates were very high across Europe in the 1950s, 60 and 70s. But they can hide the variability among a given species, based on where and how its produced. 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. As a Premium user you get access to the detailed source references and background information about this statistic. We can catch them in the wild, or grow them in fish farms. Whats even more concerning is that this only tells us about assessed shark populations. Effective fisheries management instrumental in improving fish stock status. There are several methods we use to better-understand the health of fish stocks. Naylor, R. L., Goldburg, R. J., Primavera, J. H., Kautsky, N., Beveridge, M. C., Clay, J., & Troell, M. (2000). The original source is FishStat, the database maintained by the Food and Agriculture Organization of the United Nations. Killing for no reason. This inter-war decline was due to a couple of factors: fishing became much more dangerous; and vessels were redirected from fishing towards military and other uses.3 Even after the World Wars, fish catch began to dramatically decline over the second half of the 20th century. Globally, employment in the industry has increased by 60%, but with much faster growth in aquaculture. A third assessment of global marine fisheries discards. That means that even if bycatch did not decline, the amount of discards would. Catch tells us how many were taking out. In the charts here we see the share of territorial waters that are protected in each country. Rome. Its interesting to see how common methods are across different countries. First, the feed conversion and efficiency of fish farms has improved. It, as wed expect, is a stock variable. In their analysis, Hiddink and colleagues found average recovery times (where recovery means getting back to 95% of pre-trawling biomass levels) in the range of 1.9 to 6.4 years. 11% went to aquaculture as feed for farmed fish. In 2020, global capture fisheries production was 90.3 million tonnes - a fall of 4.0 percent compared with the average over the previous three years.
