But aquaculture production has grown quickly. On the flip-side, a ratio of 0.5 means you get 2 fish back from every fish you put in. Vietnam uses the aquaculture technique to increase the production of Basa Fish to meet global demand. But Im often asked the question: What about fish and seafood? Overall we see that seafood has a relatively low environmental impact among animal protein sources. 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. This is the median impact of chicken raised in the US or Europe. For example, not allowing trawling in areas with coral reefs, or important biodiverse habitat such as seagrasses. You can see these rates by region here. (Editors), 2020. Not only does it provide an important source of protein, fish also contains other nutrients and vitamins that are important for overall health, such as vitamin A, calcium, iron and omega-3 fatty acids.5. This policy is implemented by the European Union, and was a core part of its Common Fisheries Policy reform in 2013. 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. Most fisheries across Asia do not. hotels, restaurants and catering facilities, including school and work canteens).1. Likewise, in many cases, surveys at sea stopped entirely, jeopardizing the collection of crucial data for stocks assessment across space and time. Importantly, this metric treats each fish stock as being equal, regardless of how big each stock is. Egypt: annual fish production by fish group | Statista Its an incredibly efficient way to catch seafood. Aquacultures reliance on wild fish has been weakening. On the basis of total protein and calories, plant-based foods such as legumes and soy still have a much lower impact. If we take this black trend line and continue extrapolating it into the future, it will cross 100% in 2048. Duarte, C. M., Agusti, S., Barbier, E., Britten, G. L., Castilla, J. C., Gattuso, J. P., & Worm, B. Data expressed in live weight equivalent. The list of members that have submitted their acceptance of the agreement is available here. That means, up to the point that harvested or caught fish are brought back to land. 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. Some are much more damaging than others. Sustainable fishing, by its fisheries definition, is catching just the right amount. Many of the effective solutions to reduce discards relies on effective monitoring and enforcement of fishery policies. How did they reach this conclusion? It doesnt tell us about what fish we might want to buy or avoid. If youre doing the latter, youre going to end up with lots of unwanted animals in your net. But many tuna populations are now well-managed. Kinds of frozen prepared seafood and fish consumed in the U.S. 2020. Its not the case that we put 12.6 million tonnes of feed in, and magically get 112 million tonnes of fish back. Maybe even longer. When we adjust for the different amounts of catch from each stock, we find that almost four-fifths (79%) of fish catch is sourced sustainably. Of course, it wont apply to all fisheries across these regions. Ecuador benefitted greatly from expanded production, further cementing its position as the top global exporter. However, there are a few species that are still of concern. Overall, aquaculture is an important solution to meet growing demand for seafood. One-fifth (21%) of catch from bottom trawls is discarded. Eliminating by-catch completely might be unrealistic. Food and Agriculture Organization. Schwab Foundation for Social Entrepreneurship, Centre for the Fourth Industrial Revolution. physical distancing between crew members at sea) or lack of necessary supplies (e.g. Thats part of the explanation for why feed inputs in the 1960s, 70s, 80s and 90s were higher than aquaculture production. Both of these developments have decreased upward pressure on fish prices.In September 2022, the Norwegian government announced plans to introduce a 40 percent tax on most salmon farming companies. In this case animal sources of protein can be vitally important for human health. Obviously this is not an optimal place to be in, whether you care about the fish or you care about the fishers. Over time, gear has been adapted to reduce by-catch. This is partly a result of the fact that they achieve less catch per landing than methods such as trawling or purse seine. Scientists use acoustics and other methods to monitor and estimate the abundance of fish at any given time. Most eaten brands of tuna (can or pouch) in the U.S. 2020. It shows a more stable trend in collapse stocks over the last few decades. It covers many of the worlds key fishing regions: the United States, Canada, Norway, Iceland, Europe, Peru, Chile, Argentina, high seas tuna fisheries, New Zealand, and Japan, plus most of the major fisheries of South Africa and Australia. Around 10% of the worlds seabed is shallower than 1000 meters this threshold includes all of the worlds continental shelves and areas that wed fish in. When fishers go out to catch fish, it would be great if they only caught the fish that they needed. At the same time, China will participate in the second phase of negotiations in a positive and constructive manner and look forward to an early outcome of the negotiations.. Production has continued to grow while the output of wild fisheries has slowed, or even plateaued. 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. This is because fish tend to be more efficient than chickens in converting feed into meat: that means they need less feed per kilogram. Thats why its so common: one-quarter of the worlds fish are caught this way. In fact, several species have been downgraded on the IUCNs Extinction Red List. But to get all of the amino acids (the building blocks of protein) from a plant-based diet, it needs to have the right variety of foods. These challenges were not homogeneous among countries or even within the same country, as some had better institutional, financial, technological and digital capacities to develop solutions. That means 37 million km2 of seabed is within our scope. How much of our total protein, from plant and animal sources comes from seafood? There are lots of types of seafood: not only different species, but also ways of producing them. Many have reported that Boris Worms 2006 paper has since been retracted. Previously we looked at the aggregate of tuna stocks; we can zoom in further and look at particular regional stocks. This raises the important question of what the authors meant by the term collapse and how it was calculated. Over half of the worlds fish catch. Many of our most popular stocks are well-managed and have healthy populations. But this will come at the cost of catch and income for communities that rely on it. Thats most of the fisheries across Asia, Africa and South America. Regulations in marine protected areas can vary but includes interventions such as no fishing zones; restrictions on fishing such as the type of gear that can be used; bans or restrictions on activities such as mining; and regulations on inputs to the ocean from rivers and industrial effluents. It, as wed expect, is a stock variable. It has absorbed almost all of the growth in global demand in recent decades and will continue to play a critical role in protecting wild fish populations as demand for seafood continues to rise. If it is partly fed by wild fish, perhaps more fish farms means more pressure on wild fish stocks? This has improved massively in the decades since then. In this chart we see levels of fishing intensity across the same regions. Some countries have implemented a no-discard policy a ban on discards at sea.40 This is sometimes called a landing obligation, which means that fishers must keep all of their caught fish on board and bring them back to land to declare as landings. facts. Oxford University Press. Maintaining sustainable fish stocks relies on us understanding how quickly fish populations regenerate, and balancing this with how much fish we catch. Unfortunately many in poorer countries are heavily reliant on cereals and lack this dietary diversity. In the 1960s, aquaculture was relatively niche, with an output of a few million tonnes per year. Sometimes there are claims that seem so far-fetched that its hard to imagine they need to be addressed. For example, the doors on otter trawls are very destructive; newer designs now limit the amount of impact these doors have with the seafloor. Well, they plotted the historical decline in collapsed taxa, as shown in the chart. Rebuilding marine life. Fisheries of the United States | NOAA Fisheries In an analysis published in PNAS, Jan Geert Hiddink and colleagues brought these experiments together to build a complete picture.30. If we push beyond the limits of how quickly fish populations recover, this becomes unsustainable. Lets first look at the question of how much of the seafloor is affected by trawling. Purse seine is the second most common method, accounting for just over 20% of catch. Fish How much fish do we catch from each method? The total ocean seabed spans 361 million km2.25 Thats the top bar in the chart. This mirrors the assessment of fisheries by the UN FAO. On the y-axis we have fish biomass, given as two variables. In 1995, fish farming was a very small industry, but it has grown rapidly in the last few decades. Catch tells us how many were taking out. China, Worlds Largest Seafood Producer, Ratifies WTO Deal on The Agreement on Fisheries Subsidies is the second multilateral agreement reached by the WTO since its establishment in 1995, and the first WTO agreement aimed at achieving the goal of environmental sustainable development, said Minister Wang. 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. But this is one that simply wont die it has been repeated so many times that many believe it to be true. But lets first look at total production, from the sum of these two methods. The other school of thought views fish as a resource. They dont necessarily need fishmeal and oils in their diets, but fish farmers often use them because they provide an almost perfect balance of essential nutrients such as omega-3 fatty acids. Lets first look at the stock line. Yet, compared with 2019, total production of aquatic animals in 2020 declined by 3 percent for African countries and 5 percent for countries in Oceania, most probably as a result of COVID-19. The Maximum Sustainable Yield is the sweet-spot where we can catch as much fish as possible without reducing that fish population below the most productive level. We can limit the use of trawling and, in fact, many countries have. Ocean Recovery: A sustainable future for global fisheries?. World Economic Forum, public.affairs@weforum.org. NOTES: Excluding aquatic mammals, crocodiles, alligators and caimans. All the software and code that we write is open source and made available via GitHub under the permissive MIT license. Market Reports | GLOBEFISH - Information and Analysis Farmed salmon only ranges from 4.1 to 6.2 kg CO2e: a 50% difference between the minimum and maximum. But overall, the majority in regions where we have high-quality data are at least stable, if not improving.13. Whats striking is that global wild fish catch has not increased since the early 1990s and instead remained relatively constant at around 90 to 95 million tonnes per year. Regions that manage fisheries well are constantly monitoring, and changing catch limits when necessary. Then 30% by 2037, and 50% by 2044. When we look at the amount of fish caught per unit of fishing power (the number of fishing vessels multiplied by the fishing effort per vessel) we also see a dramatic decline. The agreement prohibits support for illegal, unreported and unregulated (IUU) fishing, bans support for fishing overfished stocks and ends subsidies for fishing on the unregulated high seas. This has been good news for the health of global fish stocks. Environmental performance of blue foods. 2022 These results look at the impacts on-farm and off-farm, up to the farmgate. Global marine fisheries discards: A synthesis of reconstructed data. But their subsequent work has put forward very different conclusions from the original claims. 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). Most of the fishing methods we use have some kind of environmental impact whether its burning fuel in fishing boats; unintentionally catching fish or marine animals we dont want (bycatch); or leaving behind remnants of fishing gear. By consumption here we mean the amount thats available for consumers at the retail level. In fact, fisheries were forced to close 24 years later, in the early 1990s. 42% of the North Sea was trawled. Production reached over 1 million tonnes in 2021, and projections indicate a 30 to 35 percent increase for 2022. International salmon prices hit a ten-year high in May, which together with high prices for groundfish, pushed Norwegian export revenues up by 18 percent. Disturbance of the seabed by mobile fishing gear: a comparison to forest clearcutting. How much of the worlds ocean is protected? In the chart we see the health of fish stocks across three oceans: the Atlantic, Pacific and Indian Ocean. Like any type of animal farming, we need to feed them. The World Economic Forum, through the Friends of Ocean Action, has been a long-term supporter of the global agreement along with businesses, ocean experts and civil society organizations. Otter trawls have the lowest impact: it digs just 2.4 centimeters into the sediment, and around 6% of organisms are lost. More people are employed in wild catch than fish farming: a difference of 39 million to 21 million. These are critical questions, but to answer them we need to first agree on what sustainability actually means when it comes to fishing. So, its not just feed for fish farms. The Canadian East Coast has seen a large decline in recent years. Many fisheries are in a stable position, and not following the projected curve of collapse. Overall, COVID-19 brought a new set of challenges to national statistics systems and operations. The optimal outcome is completely different. June 29, 2022. 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. They are carried out using the ABC method This is the collection of three key metrics: A = Abundance. This means they have a much lower impact than foods such as beef or lamb. Fish and Fisheries, 6(2): 134155. The start and end year of this monitoring varied, but was around the year 2010 across each region. The balance of these two gives us an estimate of how many there really are. In countries where most fishing is subsistent Bangladesh is one example its small-scale fishing practices that dominate. We see this again in the chart here. The State of World Fisheries and Aquaculture - Publications Sea Around Us Concepts, Design and Data (seaaroundus.org). Some regions are fishing much more sustainably than others. Bottom trawling has been growing elsewhere, though. Both Albacore tunas and Yellowfin tunas moved from Near threatened to Least concern. Z., Shepon, A., Passarelli, S., Free, C. M., Viana, D. F., & Thilsted, S. H. (2021). Others lag behind, but theres no reason to think that they could not do the same. 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. Actual consumption will be a little lower due to consumer food waste. (2021). Collection of data from aquaculture facilities was also seriously affected. We see this in the other chart which plots discards since 1950. Global fish economy: Production and trade to grow in NOTES: Excluding aquatic mammals, crocodiles, alligators and caimans and algae. More than double that of chicken. So, weve included chicken for comparison.22 Chicken tends to have the lowest environmental impact of meat and dairy products much less than beef and lamb, and a bit better than pork. The State of World Fisheries and Aquaculture 2020. If that were true, within 5 years almost all of the shallow seabed would be trawled. Aquaculture is Thurstan, R. H., Brockington, S., & Roberts, C. M. (2010). Most eaten types of tuna (can or pouch) in the U.S. 2020. Those from Ethiopia and Pakistan eat only a few. WebDefinition ofAquaculture production.

In addition to the 178 million tonnes of aquatic animals, 36 million tonnes (wet weight) of algae were produced in 2020, of which 97 percent originated from aquaculture. One-quarter of the shelf in the Irish Sea was. 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. These terms might be interpreted negatively by some, but actually this is the sweet spot that fisheries are aiming for. That means that even if bycatch did not decline, the amount of discards would. Most fisheries across Europe and the Americas have good coverage. The median emissions for farmed and wild-caught salmon are similar; farmed has a slightly lower footprint of 5.1 versus 6.9 kg CO2e per kg. 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. Fish stocks are healthy across most of these regions. Several years might seem like a long time, but its actually pretty fast for an ecosystem to recover. Fisheries Research, 109(1): 8088.Valdemarsen, J.W. Some fishing methods generate much more discards than others. In the chart here we see five centuries of cod catch in Eastern Canada.1 These fishing records date back to the year 1500. The research community had previously been divided: one camp had a more optimistic take on the status of the worlds fisheries and prospects for the future; one had a more pessimistic take. First as the global distribution, shown on the map. Two-thirds were biologically sustainable, where 60% were maximally fished, and 6% were underfished. Research suggests that where stocks are healthy, a net only passes over the same spot once in a period of 3 to 10 years. Trawling, dredging and pole-and-line: what methods do we use to catch fish? A stock where we catch 1000 tonnes is counted the same as a stock where we catch 10 tonnes. 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). Tuna from the Indian Ocean has less guarantee of being from a sustainable source. How much of our animal protein comes from seafood? Although these rates have stabilized or even declined in the last few years. Its possible to get all of the protein we need from plant sources. The UN Food and Agriculture Organization (FAO) estimates that 59.5 million people globally were employed as fishers (catching wild fish) or fish farming (aquaculture) in 2018. 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. However, it increased by only 2 percent in 2020 compared with 2019. If fishers have a quota or limit on how much fish they can catch, they have to be much more careful about by-catch these unwanted fish will still count towards their quota for the day. But it does not mean an empty ocean. We can see these two schools of thought emerge in the typical diagram of sustainable fishing. Discards are not reported. That would massively overstate the efficiency of fish farms. China is the worlds largest seafood producer, producing more than 60 million tonnes in 2019. You can explore this data for any country using the + Change country button on the interactive charts. In contrast, bottom trawling is becoming less common across Europe. In this article we look at how much of the seafloor is trawled; what the consequences are; and what we can do to reduce its impacts. 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. Or, substituting lower-impact meats such as chicken and pork for beef and lamb. Restoring ocean health enables people everywhere to thrive and ensures we leave a liveable planet for generations to come. 5% went to land-based livestock such as cows, pigs and chickens. This, again, is a flow variable. This represented almost 98.1 percent of the total fish production. data than referenced in the text. Some hardy shellfish might survive, but most discarded fish are dead. Which fishing methods are responsible for the most discards? Fisheries and aquaculture production relying on export markets was more impacted than that serving domestic markets due to market closures, increased freight costs, flight cancellations and border restrictions.
