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. Our 5 million km2 of trawled seabed shown as the bottom bar is therefore equal to around 13.5% of the explorable seabed. Unfortunately this is not the case. Since then, stocks have not been able to recover due to the reopening of fisheries and their overexploitation afterwards. 90% was brought ashore and used for human food or animal feed. How much fish do we catch from each method? Tunas in the Atlantic and Pacific are managed close to their maximum sustainable yield. Nature, 591(7851), 551-563. Mar 19, 2020 -- by Thomas Gomersall For such a relatively small place, Hong Kong has a truly spectacular array of marine life. Chang cites pollution, boat traffic collisions, fishing net entanglement and coastal development as some of the major threats to these species. 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. You have permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. Only landings the fish brought back to land are recorded in most databases, such as those of the UN fisheries. How much fish do people across the world eat, and how much of our nutrition does it provide? We can catch them in the wild, or grow them in fish farms. Some fishing methods generate much more discards than others. The issue of wild fish stock depletion is not an issue for farmed seafood. Reducing discards is a good thing. But can we say anything about how they might be doing? If theyre over the limit, they will have to throw some fish back. 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. This is often measured in terms of fish stocks. It peaked in 1968, before a collapse in fish stocks led to a dramatic decline. Intensive trawling activities in Hong Kong coastal waters, which formerly constituted about 80% of the total fishing effort (Morton, 2011), had greatly depleted fish and crustacean resources. 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. Environmental performance of blue foods. This is what is called the maximum sustainable yield. This means that countries that have been successful so far tend to be those with strong fisheries policies. In many countries such as the UK, Spain and Portugal bottom trawling was intense throughout the 1950s, 60s and 70s but has since declined significantly. We see this across other species too: see shrimp, for example. Taison Chang, Chairman of the Hong Kong Dolphin Conservation Society, says that the white dolphin population dropped by more than 75% from 2003-2018 (from 188 to 32), albeit with a slight rebound to 52 in 2019numbers so low that they seriously compromise population viability. Many of the tuna stocks that were the biggest concern have managed to turn things around. This has been confirmed from some smaller scientific surveys in the region. Production has continued to grow while the output of wild fisheries has slowed, or even plateaued. From the chart we see that most are above one: the maximum sustainable yield. The same is true in our comparison to chicken. Human activity, such as overfishing, puts our oceans at risks and could deplete entire populations of marine life A marine ecologist gives tips on how to make changes in your diet and be sure the. The sustainability of wild fish stocks is not something that we discuss here, but is a crucial metric to consider. At the time there was a lack of high-quality data on fish abundance, so there was only catch data to go on. Licenses: All visualizations, data, and articles produced by Our World in Data are open access under the Creative Commons BY license. Available at: www.protectedplanet.net. Proceedings of the National Academy of Sciences, 114(1), 178-183. Unfortunately there are key regions where we have very little data. Its stocks have now fallen below one, and look to be continuing downwards. Many countries have reduced the use of trawling. Those from Ethiopia and Pakistan eat only a few. . Naylor, R. L., Hardy, R. W., Buschmann, A. H., Bush, S. R., Cao, L., Klinger, D. H., & Troell, M. (2021). But, of course, fishing is an industry that dates back much further. For example, the doors on otter trawls are very destructive; newer designs now limit the amount of impact these doors have with the seafloor. 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. Rome, FAO. Overall, two-thirds of fisheries are sustainable, providing four-fifths of our seafood. Many of our most popular stocks are well-managed and have healthy populations. Not all aquaculture species are fed from animal sources, but many are. Many types have a lower carbon footprint than chicken (those that are higher are around 20-30% higher). Some countries in the world eat close to 100 kilograms of seafood per person each year. Schijns, R., Froese, R., Hutchings, J. Fisheries that are not carrying out these assessments will struggle to maintain this balance. By looking at Hong Kong you can get a good snapshot for who is exporting shark fin," Andy points out. Its where fish catch is equal to the reproduction rate. In addition, the European Commission banned bottom trawling in deep waters those below 800m in depth in 2016. We see a steep rise in fish catch over the first half of the 20th century. Hong Kongs soul was shaped by the sea now its our turn to take care of it. Conservation biology, 12(6), 1180-1197. Fish are killed needlessly; and the fact that these fish are not sold or eaten means that no one benefits from more income or food. In their paper, published in Nature, researchers Ruth Thurstan and colleagues reconstruct UK fisheries trends dating back more than a century.2 This measures catch of bottom-dwelling fish excluding shellfish. Fishers also catch marine life that they dont want. You can see these rates by region here. 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. We see that in the chart below, which shows the impact of four types: otter trawling; beam trawling; towed dregs; and hydraulic dredging. Even under the best-case scenario - with moderate ocean-warming caused by climate change and a 50 per cent decline in fishing activity, the South China Sea is projected to lose US$6.5 billion of . Lets first understand the amount of wild fish that is used as feed. We see the same in Japan, where catch peaked in 1972 at 4 million tonnes, and has since fallen by around 90% to 400,000 tonnes. Or in the content of the total seabed area, its 1.4%. The bahaba is valuable because its swimming bladder is a traditional Chinese medicine, says Chan, explaining that one dried catty [600g] of bahaba swimming bladder can fetch up to HK$1 million. We will look at whats happening to global fish stocks in a follow-up article. This is reflected in the fact that the Black Sea is very overfished. Discards can be dead or alive, but the survival rate is low. Hiddink, J. G., Jennings, S., Sciberras, M., Szostek, C. L., Hughes, K. M., Ellis, N., & Kaiser, M. J. Trawling rates were very high across Europe in the 1950s, 60 and 70s. Over fishing: Hong Kong's fishing crisis finally arrives 10.1016/j.marpolbul.2005.07.008 Source PubMed Authors: Brian Morton University of Hong Kong Request full-text Discover the world's. Managing bycatch and discards: how much progress are we making and how can we do better? December 2, 2013 Japan, China, the U.S., Indonesia, Chinese Taipei and South Korea have been named by Pew Charitable Trusts on a "shame list" of countries responsible for overfishing tuna in the Pacific. Depleting fisheries faster than they can replenish endangers key species in oceanic food chains, which can lead to the system's collapse. 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. Costello, M. J., Cheung, A., & De Hauwere, N. (2010). Their web platform Sea Around Us is an excellent resource to understand global fisheries. Many thanks to Ray Hilborn, Michael Melnychuk, Max Mossler and Daniel Hively from RAM Legacy Stock Assessment Database for the provision of data and feedback for this project. In other words, if we assume taxa continued to collapse at a constant rate, it would reach zero by mid-century. We catch between 25 and 30 million tonnes each year. This gives us insights on how modern-day fishing compares to the more distant past. A study in 2017 found that despite making up just 0.03% of China's. Almost 10 tonnes of shark fin worth HK$10 million (US$1.3 million) were seized by Hong Kong customs in October 2021 as part of a record HK$210 million haul of luxury goods destined for the mainland. Single-use plastics pose a serious threat to marine-life at every level of the food chain. If you choose wild-caught salmon you could be picking a low-carbon, or a high-carbon protein source. In the 1960s, Portugal was catching around 1 million tonnes each year. PHOTOGRAPH BY CARON WONG @ 114E HONG KONG REEF FISH SURVEY. 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. Others lag behind, but theres no reason to think that they could not do the same. December 31, 2021. Finally, we can ban trawling in specific locations where the habitat is particularly sensitive. Whats even more concerning is that this only tells us about assessed shark populations. One-quarter of the shelf in the Irish Sea was. In some countries, seafood dominates. How much of our protein comes from seafood? Catch may be low because populations have been depleted. 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. Thankfully, aquacultures reliance on wild fish has declined over the last few decades. Sampled fish are taken to assess the age and population growth rate of the population. This has been another major factor in the territorys dwindling fish numbers and the citys impact on fisheries elsewhere. and Baum, J.K. (2012) Evaluating the knowledge base and status of commercially exploited marine species with the RAM Legacy Stock Assessment Database. The average results across different fishing methods is shown in the chart. All rights reserved, Do Not Sell or Share My Personal Information. How much of the worlds protein comes from fish? Small-scale fisheries contribute very little. 21% of catch comes from overfished populations. This is back to levels in the late 1950s. Hong Kong's story is an early example of overfishing causing local shark and ray extinctions, a pattern that has repeated itself many times around the world. Fishers sometimes bring by-catch back to land, to eat or sell. Most farmed seafood needs less land and freshwater, and causes less nitrogen and phosphorus pollution. One option is therefore to ban specific types of gear rather than banning the practice completely. "Hong Kong is the largest trading centre for shark fin; 40% of the global supply of shark fin passes through or is consumed here. In Hong Kong there are approximately 3700 fishing vessels, most are sampans and small fishing boats engaged in inshore fishing, but the real damage is caused by the 1100 or so large commercial trawlers. Disturbance of the seabed by mobile fishing gear: a comparison to forest clearcutting. These results look at the impacts on-farm and off-farm, up to the farmgate. Here were looking at five key metrics: greenhouse gas emissions, land use, freshwater use, and nitrogen and phosphorus pollution. That is partly why they have such low emissions; and they need no additional land either. We can limit the use of trawling and, in fact, many countries have. This ratio tells us about fish inputs, which is only one part of their total diet. Hilborn, R., Amoroso, R. O., Anderson, C. M., Baum, J. K., Branch, T. A., Costello, C., & Ye, Y. Sustainable consumption and fishing practices are key to protecting Hong Kongs marine ecosystem, says National Geographic Explorer Stanley Shea. 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). Other surveys of trawling efforts across the region show similar declines. This is incompatible with restoring populations to their historical levels, because we cant do that and catch lots of fish at the same time. If you have a FIFO greater than 1, you need more fish inputs than you get back from your fish farm. When we cut down primary rainforest we are locking ourselves into a recovery period of many decades. Endemic to China, the bahaba was once commonly found in the Pearl River estuary, with spawning grounds in Hong Kong, but is today critically endangered. This gives us what is called the discard rate what percentage of the total catch is thrown back into the water. In the chart here we see five centuries of cod catch in Eastern Canada.1 These fishing records date back to the year 1500. Second, this is an issue that is often hidden from official statistics. Many types of seafood have a lower impact than chicken. But we can go even further and look at specific tuna species, such as bluefin or yellowfin. If intensity is greater than one then were overfishing. Thankfully we are not completely blind. Please consult our full legal disclaimer. On the other hand, farmed salmon, trout, and eel still have unfavourable ratios. The world produces around 200 million tonnes of fish and seafood every year. Again, this is measured relative to the intensity at the maximum sustainable yield. 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. In fact, several species have been downgraded on the IUCNs Extinction Red List. At the industry, national or global level we want to know this so we can take action on the stocks that are not doing well. Particularly since the late 1980s, annual production has increased rapidly. Combined, underfished and maximally fished would be considered to be sustainable because fish stocks are not declining. It includes all of the inputs into production, such as fish feed, or fuel use on fisheries. There are several methods we use to better-understand the health of fish stocks. Twenty-four countries have closed, or attempted to close their sea . Nearly all of the growth in seafood production in recent decades has come from aquaculture; wild fish catch has changed very little. For the best Barrons.com experience, please update to a modern browser. 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. Catch that is not the species were targeting is called by-catch. We see this in the previous chart, where they lie below the optimal level of one. Naylor, R. L., Goldburg, R. J., Primavera, J. H., Kautsky, N., Beveridge, M. C., Clay, J., & Troell, M. (2000). For the ecosystem to get back to its pre-trawling state takes a few years, if its left alone. 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. HONG KONG (AFP) - Experts said on Tuesday (Nov 3) that some fish species are close to extinction in the South China Sea due to overfishing fuelled by a growing appetite for seafood. Nature, 405(6790), 1017-1024. 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. For billions of people across the world, fish is an important source of nutrition. Ultimately, however, he says that this strategy can only be successful if enough people participate to make it scalable, and thus economically attractiveand that businesses have to help by making sustainable options more readily available to the public. In the chart we see the spread of greenhouse gas emissions among the different types of seafood. Portuguese catch from bottom trawling has fallen by 90% since the 1960s.32 In 2016, the European Commission also banned bottom trawling in deeper water, below 800 meters. Its useful to look at all of these impacts in case there are large trade-offs between them. A 20-year retrospective review of global aquaculture. This mirrors the assessment of fisheries by the UN FAO. This policy is implemented by the European Union, and was a core part of its Common Fisheries Policy reform in 2013. & Mainprize, B.M. That was 10.8% of the total catch. Bottom trawling drags a structure along the seabed at various depths in the sediment depending on the specific method to dislodge organisms such as crustaceans. Diversity in DangerOne such species is the Bahaba taipingensis, also known as the giant yellow croaker or yellow-lipped croaker. If youre not familiar with this research, it can be difficult to understand exactly what each method looks like, and what it entails. National Geographic Explorer and Marine Programme Director at oceanic-conservation NGO Bloom Association Hong Kong, Stan Shea illustrates the extent of the problem: Records show that, decades ago, Hong Kong had such high yields of seafood that it supported 90% of local demand. This is why I dont find the comparison between dredging and rainforest clearing to be a particularly helpful one. Worm, B., Barbier, E. B., Beaumont, N., Duffy, J. E., Folke, C., Halpern, B. S., & Watson, R. (2006). Pole-and-line, longline, and gillnet methods are more common in lower-income countries where much of the fishing activity is subsistence or small-scale. This is based on summary visuals from the Marine Stewardship Council. Lets then turn towards the health of fish across the regions we do have good assessments for. The case of the UK, Portugal and Spain are shown in the chart. Purse seine is the second most common method, accounting for just over 20% of catch. Lets look at a few of these species in more detail: tuna, which is doing surprisingly well, and sharks which are not. This 1998 paper, for example, compares trawling to Amazonian forest clearcutting.Watling, L., & Norse, E. A. How Does Overfishing Impact Hong Kong from a Socio-Economic Perspective? The chart here show the distribution of wild fish catch by country. Which fishing methods are responsible for the most discards? Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). Second, as the regional breakdown, where you can also add and compare countries using the If aquaculture was putting pressure on fish production, its not obvious from the total catch. But, this is not reflected in the data on fishing activity. The tension between these two schools becomes obvious. In the chart we see the same metric as before fish stocks measured by biomass across different types. Hong Kong-based Avant Meats offered . This is followed by Indonesia, India, Vietnam and the United States. We see that much more of the worlds national waters are protected than international ones. As we will see later, this prediction has not played out in reality. We've detected you are on Internet Explorer. Underfished: this is when fish catch is less than the reproduction rate of fish populations. That is shown by the second bar. As of 2021, 7.7% of the total ocean is protected. More than two hundred . The original source is FishStat, the database maintained by the Food and Agriculture Organization of the United Nations. This is because fish tend to be more efficient than chickens in converting feed into meat: that means they need less feed per kilogram. Beam trawls lose 14%. 633. The other chart shows us how employment has changed since 1995. Most of the research, industry, and policymaking is geared towards the second school: viewing fish as a resource. It shows us first, in red, the observations in the Worm et al. But, based on what we know (and especially, the fact that we dont know a lot), the consensus is that many of these fish stocks are not in a healthy place. Where did this claim come from, and is it true? How are populations of tuna, cod, mackerel or sharks holding up? As these fish tend to also have a low carbon and land footprint, farmed fish can be a low-impact source of protein. This project relies on multiple sources but primarily the FishStat database published by the Food and Agriculture Organization of the United Nations. But they can hide the variability among a given species, based on where and how its produced. But this is one that simply wont die it has been repeated so many times that many believe it to be true. The impacts across the seafood products are shown in the charts. Whats the story here? That means 37 million km2 of seabed is within our scope. Effective fisheries management instrumental in improving fish stock status. Without significant action, Chang says that both species may disappear from the HKSAR in the foreseeable future, and that, as they are at the top of the food chain, their decline reflects a systemic failure in the marine ecosystem.. Thats why its so common: one-quarter of the worlds fish are caught this way. According to Pew, the "Pacific 6" are responsible for 80 percent 111,482 metric tons in 2011 of the annual catch of bigeye tuna. Well, first, the very fact that we dont have good data is itself bad news. Is it becoming more or less common? But, of course, they do only recover if we leave them alone. Over half of the worlds fish catch. Eliminating by-catch completely might be unrealistic. Most fisheries are aiming for this sweet spot: catching not too much; not too little; just right. Now that we have some understanding of what each of these methods mean, lets look at how common each is. This gear is used across the world, but there are some general patterns to where certain methods are more widely used. Unsurprisingly, Asia is home to most of the worlds fishers and fish farmers, employing 50 million of the 59 million globally. Marine scientists do reconstruct and estimate discards. (2006). We saw previously that shark stocks were now below the maximum sustainable yield, and continue to decline. Overfishing is the reason: a common problem around the world. Abundance and biology tell us how many fish we would otherwise expect to be there before we remove any. Theres one key metric that we need to understand the efficiency of fish feed: the FIFO ratio. The effects of 118 years of industrial fishing on UK bottom trawl fisheries. Many have reported that Boris Worms 2006 paper has since been retracted. Chang says that the governments banning of trawling vessels in 2012, expansion of marine protected areas, and provision of training programs for the fishing industry, among other measures, are all steps in the right direction, but he estimates that it would require a complete ban on all commercial fishing in Hong Kong waters for two to three years to allow fish populations to meaningfully recovera measure that seems unlikely at present. Regions that manage fisheries well are constantly monitoring, and changing catch limits when necessary. Proceedings of the National Academy of Sciences, 114(31), 8301-8306. Of course, it wont apply to all fisheries across these regions. The breakdown of employment by region, and the split between fisheries and fish farming is shown in the chart.
