'''Seafood''' is any form of [[Marine life|sea life]] regarded as food by humans, prominently including [[Fish as food|fish]] and [[shellfish]]. Shellfish include various species of [[Mollusca|mollusc]]s (e.g., bivalve molluscs such as [[clam]]s, [[oyster]]s, and [[mussel]]s, and [[cephalopod]]s such as octopus and squid), [[crustacean]]s (e.g. shrimp, crabs, and lobster), and [[echinoderm]]s (e.g. sea cucumbers and sea urchins). Historically, [[marine mammal]]s such as [[cetacean]]s ([[whale]]s and [[dolphin]]s) as well as [[Pinniped|seals]] have been eaten as food, though that happens to a lesser extent in modern times. Edible sea plants such as some [[Edible seaweed|seaweeds]] and [[microalgae]] are widely eaten as [[:Category:edible seaweeds|sea vegetables]] around the world, especially in Asia. 

Seafood is an important source of (animal) [[protein]] in many [[Diet (nutrition)|diets]] around the world, especially in coastal areas. [[Semi-vegetarianism|Semi-vegetarians]] who consume seafood as the only source of meat are said to adhere to [[pescetarianism]].

The harvesting of [[Wild fisheries|wild seafood]] is usually known as [[fishing]] or [[hunting]], while the cultivation and farming of seafood is known as [[aquaculture]] and [[fish farming]] (in the case of fish). Most of the seafood harvest is consumed by humans, but a significant proportion is used as [[fish food]] to farm other fish or rear [[farm animals]]. Some seafoods (i.e. [[kelp]]) are used as food for other plants (a [[fertilizer]]). In these ways, seafoods are used to produce further food for human consumption. Also, products such as [[fish oil]], [[spirulina (dietary supplement)|spirulina]] tablets, fish collagen, and [[chitin]] are made from seafoods. Some seafood is fed to [[aquarium]] fish, or used to feed domestic pets such as [[cat]]s. A small proportion is used in medicine or is used industrially for nonfood purposes (e.g. [[leather]]).

Fishing scenes are rarely represented in [[ancient Greek]] culture, a reflection of the low social status of fishing. However, [[Oppian|Oppian of Corycus]], a Greek author wrote a major treatise on sea fishing, the ''Halieulica'' or ''Halieutika'', composed between 177 and 180. This is the earliest such work to have survived to the modern day. The consumption of fish varied by the wealth and location of the household. In the Greek islands and on the coast, fresh fish and seafood ([[Squid as food|squid]], [[Octopus as food|octopus]], and [[shellfish]]) were common. They were eaten locally but more often transported inland. [[Sardines as food|Sardines]] and [[Anchovies as food|anchovies]] were regular fare for the citizens of Athens. They were sometimes sold fresh, but more frequently salted. A [[stele]] of the late 3rd century BCE from the small Boeotian city of [[Akraiphia]], on [[Lake Copais]], provides us with a list of fish prices. The cheapest was ''skaren'' (probably [[parrotfish]]) whereas [[Atlantic bluefin tuna]] was three times as expensive.<ref>Dalby, p.67.</ref> Common salt water fish were [[yellowfin tuna]], [[red mullet]], [[Batoidea|ray]], [[swordfish]], or [[sturgeon]], a delicacy that was eaten salted. Lake Copais itself was famous in all of Greece for its [[Eel as food|eels]], celebrated by the hero of ''[[The Acharnians]]''. Other freshwater fish were [[esox|pike fish]], [[carp]], and the less appreciated [[catfish]].

Pictorial evidence of [[Ancient Rome|Roman]] fishing comes from [[mosaic]]s.<ref>[http://museum.agropolis.fr/english/pages/expos/aliments/poissons/images/mosaique.htm Image of fishing illustrated in a Roman mosaic] {{Webarchive|url=https://web.archive.org/web/20110717033618/http://museum.agropolis.fr/english/pages/expos/aliments/poissons/images/mosaique.htm |date=17 July 2011 }}.</ref> At a certain time, the [[goatfish]] was considered the epitome of luxury, above all because its scales exhibit a bright red colour when it dies out of water. For this reason, these fish were occasionally allowed to die slowly at the table. There even was a recipe where this would take place ''in Garo'', in the [[Garum|sauce]]. At the beginning of the Imperial era, however, this custom suddenly came to an end, which is why ''mullus'' in the feast of [[Trimalchio]] (see ''the [[Satyricon]]'') could be shown as a characteristic of the ''[[parvenu]]'', who bores his guests with an unfashionable display of dying fish.

In [[medieval]] times, seafood was less prestigious than other animal meats, and was often seen as merely an alternative to meat on fast days. Still, seafood was the mainstay of many coastal populations. [[Kipper]]s made from herring caught in the [[North Sea]] could be found in markets as far away as [[Constantinople]].<ref>Adamson (2002), p. 11.</ref> While large quantities of fish were eaten fresh, a large proportion was salted, dried, and, to a lesser extent, smoked. [[Stockfish]] - cod that was split down the middle, fixed to a pole, and dried - was very common, though preparation could be time-consuming, and meant beating the dried fish with a mallet before soaking it in water. A wide range of [[Mollusca|mollusk]]s (including [[oyster]]s, [[Mussel#As food|mussel]]s and [[scallop]]s) were eaten by coastal and river-dwelling populations, and freshwater [[Crayfish as food|crayfish]] were seen as a desirable alternative to meat during fish days. Compared to meat, fish was much more expensive for inland populations, especially in Central Europe, and therefore not an option for most.<ref>Adamson (2004), pp. 45–39.</ref>

Modern knowledge of the reproductive cycles of aquatic species has led to the development of [[Fish hatchery|hatcheries]] and improved techniques of [[fish farming]] and [[aquaculture]]. A better understanding of the [[shellfish poisoning|hazards]] of eating raw and undercooked fish and shellfish has led to improved preservation methods and processing.

The main seafood groups can be divided into larger [[predator fish]] ([[Shark meat|sharks]], [[Tuna as food|tuna]], [[billfish]], [[mahi-mahi]], [[Mackerel as food|mackerel]], [[Salmon as food|salmon]]) and smaller [[forage fish]] ([[Herring as food|herring]], [[Sardines as food|sardines]], [[sprat]]s, [[Anchovies as food|anchovies]], [[menhaden]]). The smaller forage fish feed on plankton, and can accumulate toxins to a degree. The larger predator fish feed on the forage fish, and accumulate toxins to a much higher degree than the forage fish.

| valign= top | [[Bivalve]]s, sometimes referred to as [[clam]]s, have a protective shell in two hinged parts. A [[Valve (mollusc)|valve]] is the name used for the protective shell of a bivalve, so bivalve literally means ''two shells''. Important seafood bivalves include [[oyster]]s, [[scallop]]s, [[mussel]]s and [[cockle (bivalve)|cockle]]s. Most of these are [[filter feeder]]s which bury themselves in sediment on the [[seabed]] where they are safe from [[predation]]. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some, such as scallops, can [[nekton|swim]]. Bivalves have long been a part of the diet of coastal communities. Oysters were [[oyster farming|cultured]] in ponds by the Romans and [[mariculture]] has more recently become an important source of bivalves for food.

| valign= top | Cephalopods, except for [[nautilus]], are not protected by an external shell. Cephalopod literally means ''head-foots'', because they have limbs which appear to issue from their head. They have excellent vision and high intelligence. Cephalopods propel themselves with a water jet and lay down "smoke screens" with [[Cephalopod ink|ink]]. Examples are [[octopus]], [[squid]] and [[cuttlefish]]. They are eaten in many cultures. Depending on the species, the arms and sometimes other body parts are prepared in various ways. Octopus must be boiled properly to rid it of slime, smell, and residual ink. Squid are popular in Japan. In Mediterranean countries and in English-speaking countries squid are often referred to as [[calamari]].<ref name="MW">{{cite dictionary|url=http://m-w.com/dictionary/calamari|title=Definition of calamari|date=18 August 2023 |dictionary=[[Merriam-Webster|Merriam-Webster's]] Online Dictionary}}</ref> Cuttlefish is less eaten than squid, though it is popular in Italy and [[Dried shredded squid|dried, shredded cuttlefish]] is a snack food in East Asia.

| valign= top | [[Jellyfish]] are soft and gelatinous, with a body shaped like an umbrella or bell which pulsates for locomotion. They have long, trailing tentacles with stings for capturing prey. They are found free-swimming in the [[water column]] in all oceans, and are occasionally found in freshwater. Jellyfish must be dried within hours to prevent spoiling. In Japan they are regarded as a delicacy. Traditional processing methods are carried out by a jellyfish master. This involve a 20 to 40-day multi-phase procedure which starts with removing the gonads and [[mucous membrane]]s. The umbrella and oral arms are then treated with a mixture of [[Edible salt|table salt]] and [[alum]], and compressed. Processing reduces liquefaction, odor, the growth of spoilage organisms, and makes the jellyfish drier and more acidic, producing a crisp and crunchy texture. Only [[scyphozoan]] jellyfish belonging to the order [[Rhizostomeae]] are harvested for food; about 12 of the approximately 85 species. Most of the harvest takes place in southeast Asia.<ref>{{cite journal | doi = 10.1023/A:1011879821323 | last1 = Omori | first1 = M. | last2 = Nakano | first2 = E. | name-list-style =vanc | date = 2001 | title = Jellyfish fisheries in southeast Asia | journal = Hydrobiologia | volume = 451 | issue = 1–3 | pages = 19–26 | bibcode = 2001HyBio.451...19O | s2cid = 6518460 }}</ref><ref>{{cite journal | last1 = Hsieh | first1 = Yun-Hwa P | last2 = Leong | first2 = F-M | last3 = Rudloe | first3 = J | date = 2001 | title = Jellyfish as food | journal = Hydrobiologia | volume = 451 | issue = 1–3| pages = 11–17 | doi = 10.1023/A:1011875720415 | bibcode = 2001HyBio.451...11P | s2cid = 20719121 }}</ref><ref>{{cite journal | last1 = Li | first1 = Jian-rong | last2 = Hsieh | first2 = Yun-Hwa P | date = 2004 | title = Traditional Chinese food technology and cuisine | url = http://apjcn.nhri.org.tw/server/APJCN/13/2/147.pdf | journal = Asia Pacific J Clin Nutr | volume = 13 | issue = 2| pages = 147–155 | pmid = 15228981 }}</ref>

Fish is a highly [[Decomposition|perishable]] product: the "fishy" smell of dead fish is due to the breakdown of [[amino acid]]s into [[Polyamine|biogenic amines]] and [[ammonia]].<ref>N. Narain and Nunes, M.L. Marine Animal and Plant Products. ''In:'' Handbook of Meat, Poultry and Seafood Quality, L.M.L. Nollet and T. Boylston, eds. Blackwell Publishing 2007, p 247.</ref>

Live [[food fish]] are often transported in tanks at high expense for an [[live food fish trade|international market]] that prefers its seafood killed immediately before it is cooked. Delivery of live fish without water is also being explored.<ref>{{Cite web |title=WO2005039280 - PROCESS FOR TRANSPORT OF LIVE FISH WITHOUT WATER |url=https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2005039280 |access-date=15 May 2025 |website=patentscope.wipo.int}}</ref> While some seafood [[restaurant]]s keep live fish in [[aquarium|aquaria]] for display purposes or cultural beliefs, the majority of live fish are kept for dining customers. The live food fish trade in [[Hong Kong]], for example, is estimated to have driven imports of live food fish to more than 15,000 [[tonne]]s in 2000. Worldwide sales that year were estimated at US$400&nbsp;million, according to the World Resources Institute.<ref>[http://marine.wri.org/pubs_content_text.cfm?ContentID=645 The World Resources Institute, The live reef fish trade] {{webarchive|url=https://web.archive.org/web/20070207183454/http://marine.wri.org/pubs_content_text.cfm?ContentID=645 |date=7 February 2007 }}</ref>

If the [[cool chain]] has not been adhered to correctly, food products generally decay and become harmful before the [[Shelf life|validity date]] printed on the package. As the potential harm for a consumer when eating rotten fish is much larger than for example with dairy products, the [[Food and Drug Administration (United States)|U.S. Food and Drug Administration]] (FDA) has introduced regulation in the USA requiring the use of a [[time temperature indicator]] on certain fresh chilled seafood products.<ref>{{cite web|url=https://www.fda.gov/ICECI/EnforcementActions/WarningLetters/2003/ucm147270.htm |title=La Rosa Logistics Inc 14-Jan-03 |publisher=Fda.gov |access-date=2012-04-02}}</ref>

Because fresh fish is highly perishable, it must be eaten promptly or discarded; it can be kept for only a short time. In many countries, fresh fish are [[Fish fillet|filleted]] and displayed for sale on a bed of [[crushed ice]] or [[refrigeration|refrigerated]]. Fresh fish is most commonly found near bodies of water, but the advent of refrigerated [[Refrigerator car|train]] and [[Refrigerator truck|truck]] [[transportation]] has made fresh fish more widely available inland.<ref>{{Cite journal |last=Hicks |first=Doris T. |date=2016-10-28 |title=Seafood Safety and Quality: The Consumer's Role |journal=Foods |volume=5 |issue=4 |pages=71 |doi=10.3390/foods5040071 |issn=2304-8158 |pmc=5302431 |pmid=28231165 |doi-access=free }}</ref>

Long term [[Food preservation|preservation]] of fish is accomplished in a variety of ways. The oldest and still most widely used techniques are [[Stockfish|drying]] and [[salting (food)|salting]]. [[Desiccation]] (complete drying) is commonly used to preserve fish such as [[cod]]. Partial drying and salting are popular for the preservation of fish like [[herring]] and [[mackerel]]. Fish such as [[salmon]], [[tuna]], and [[herring]] are cooked and [[canning|canned]]. Most fish are filleted before canning, but some small fish (e.g. [[sardine]]s) are only [[decapitation|decapitated]] and gutted before canning.<ref>{{Cite journal |last1=Messina |first1=Concetta Maria |last2=Arena |first2=Rosaria |last3=Ficano |first3=Giovanna |last4=Randazzo |first4=Mariano |last5=Morghese |first5=Maria |last6=La Barbera |first6=Laura |last7=Sadok |first7=Saloua |last8=Santulli |first8=Andrea |date=2021-10-21 |title=Effect of Cold Smoking and Natural Antioxidants on Quality Traits, Safety and Shelf Life of Farmed Meagre (Argyrosomus regius) Fillets, as a Strategy to Diversify Aquaculture Products |journal=Foods |volume=10 |issue=11 |pages=2522 |doi=10.3390/foods10112522 |issn=2304-8158 |pmc=8619432 |pmid=34828803 |doi-access=free }}</ref>

Seafood is consumed all over the world; it provides the world's prime source of high-quality [[protein]]: 14–16% of the animal protein consumed worldwide; over one billion people rely on seafood as their primary source of animal protein.<ref>World Health Organization [https://web.archive.org/web/20061122184857/http://www.who.int/nutrition/topics/3_foodconsumption/en/index5.html].</ref><ref>{{cite journal | last1 = Tidwell | first1 = James H. | last2 = Allan | first2 = Geoff L. | date = 2001 | title = Fish as food: aquaculture's contribution Ecological and economic impacts and contributions of fish farming and capture fisheries | journal = EMBO Reports | volume = 2 | issue = 11| pages = 958–963 | doi = 10.1093/embo-reports/kve236 | pmc=1084135 | pmid=11713181}}</ref> Fish is among the most common [[food allergy|food allergens]].

Since 1960, annual global seafood consumption has more than doubled to over 20&nbsp;kg per capita. Among the top consumers are Korea (78.5&nbsp;kg per head), Norway (66.6&nbsp;kg) and Portugal (61.5&nbsp;kg).<ref>[https://ec.europa.eu/jrc/en/news/how-much-fish-do-we-consume-first-global-seafood-consumption-footprint-published How much fish do we consume? First global seafood consumption footprint published] ''European Commission science and knowledge service''. Last update: 27/ September 2018.</ref>

The UK [[Food Standards Agency]] recommends that at least two portions of seafood should be consumed each week, one of which should be oil-rich. There are over 100 different types of seafood available around the coast of the UK.

Oil-rich fish such as [[mackerel]] or [[herring]] are rich in long chain [[Omega-3]] oils. These oils are found in every cell of the human body, and are required for human biological functions such as brain functionality.

Whitefish such as haddock and cod are very low in fat and calories which, combined with oily fish rich in [[Omega-3]] such as [[mackerel]], [[sardine]]s, fresh [[tuna]], [[salmon]] and [[trout]], can help to protect against [[coronary heart disease]], as well as helping to develop strong bones and teeth.

[[Shellfish]] are particularly rich in [[zinc]], which is essential for healthy skin and muscles as well as fertility. [[Casanova]] reputedly ate 50 [[oyster]]s a day.<ref>Slovenko R (2001) [http://heinonline.org/HOL/LandingPage?collection=journals&handle=hein.journals/jpsych29&div=12&id=&page= "Aphrodisiacs-Then and Now"] ''Journal of Psychiatry and Law'', '''29''': 103f.</ref><ref>{{cite book|author=Patrick McMurray|title=Consider the Oyster: A Shucker's Field Guide|url=https://books.google.com/books?id=MJHU67VwJ9kC|year=2007|publisher=St. Martin's Press|isbn=978-0-312-37736-6|page=15}}</ref>

==Texture and taste==
Over 33,000 [[species]] of fish and many more marine invertebrate species have been identified.<ref>[[FishBase]]: [http://www.fishbase.org/search.php October 2017 update.] Retrieved 30 December 2017.</ref> Bromophenols, which are produced by marine algae, give marine animals an odor and taste that is absent from freshwater fish and invertebrates. Also, a chemical substance called dimethylsulfoniopropionate (DMSP) that is found in red and green algae is transferred into animals in the marine food chain. When broken down, dimethyl sulfide (DMS) is produced, and is often released during food preparation when fresh fish and shellfish are heated. In small quantities it creates a specific smell one associates with the ocean, but in larger quantities gives the impression of rotten seaweed and old fish.<ref>{{cite web| url = https://www.americanscientist.org/article/the-science-of-seaweeds| title = The Science of Seaweeds {{!}} American Scientist| date = 6 February 2017}}</ref> Another molecule known as [[Trimethylamine N-oxide|TMAO]] occurs in fishes and gives them a distinct smell. It also exists in freshwater species, but becomes more numerous in the cells of an animal the deeper it lives, so fish from the deeper parts of the ocean have a stronger taste than species that live in shallow water.<ref>{{cite web| url = http://www.bbc.com/earth/story/20150129-life-at-the-bottom-of-the-ocean| title = BBC – Earth – What does it take to live at the bottom of the ocean?}}</ref> Eggs from seaweed contain sex pheromones called dictyopterenes, which are meant to attract the sperm.

[[File:Barracuda with prey.jpg|thumb|[[Barracuda]] found in Florida are avoided due to a high risk of ciguatera.

[[Scombroid food poisoning]], is also a seafood illness.

[[Fish]] and [[shellfish]] have a natural tendency to concentrate inorganic and organic toxins and pollutants in their bodies, including [[methylmercury]], a highly toxic organic compound of mercury, polychlorinated biphenyls (PCBs), and microplastics. Species of fish that are high on the [[food chain]], such as [[Shark meat|shark]], [[swordfish]], [[king mackerel]], [[albacore tuna]], and [[tilefish]] contain higher concentrations of these bioaccumulates. This is because bioaccumulates are stored in the muscle tissues of fish, and when a predatory fish eats another fish, it assumes the entire body burden of bioaccumulates in the consumed fish. Thus species that are high on the [[food chain]] amass body burdens of bioaccumulates that can be ten times higher than the species they consume. This process is called [[biomagnification]].<ref>{{Cite journal |last1=Smith |first1=Madeleine |last2=Love |first2=David C. |last3=Rochman |first3=Chelsea M. |last4=Neff |first4=Roni A. |date=2018 |title=Microplastics in Seafood and the Implications for Human Health |journal=Current Environmental Health Reports |volume=5 |issue=3 |pages=375–386 |doi=10.1007/s40572-018-0206-z |issn=2196-5412 |pmc=6132564 |pmid=30116998|bibcode=2018CEHR....5..375S }}</ref>

Man-made disasters can cause localized hazards in seafood which may spread widely via piscine food chains. The first occurrence of widespread [[mercury poisoning]] in humans occurred this way in the 1950s in [[Minamata, Kumamoto|Minamata]], [[Japan]]. Wastewater from a nearby chemical factory released methylmercury that accumulated in fish which were consumed by humans. Severe mercury poisoning is now known as [[Minamata disease]].<ref>{{Cite journal|last=Osiander|first=A.|date=2002-10-01|title=Minamata: Pollution and the Struggle for Democracy in Postwar Japan, by Timothy S.

A widely cited study in [[JAMA (journal)|JAMA]] which synthesized government and [[MEDLINE]] reports, and meta-analyses to evaluate risks from methylmercury, dioxins, and polychlorinated biphenyls to cardiovascular health and links between fish consumption and neurologic outcomes concluded that: <blockquote>"The benefits of modest fish consumption (1-2 servings/wk) outweigh the risks among adults and, excepting a few selected fish species, among women of childbearing age.

==Sustainability==

Research into population trends of various species of seafood is pointing to a global collapse of seafood species by 2048. Such a collapse would occur due to pollution and [[overfishing]], threatening oceanic ecosystems, according to some researchers.<ref>[http://www.boston.com/news/nation/washington/articles/2006/11/03/world_seafood_supply_could_run_out_by_2048_researchers_warn/ World Seafood Supply Could Run Out by 2048 Researchers Warn] boston.com.

A major international scientific study released in November 2006 in the journal ''[[Science (journal)|Science]]'' found that about one-third of all fishing stocks worldwide have collapsed (with a collapse being defined as a decline to less than 10% of their maximum observed abundance), and that if current trends continue all fish stocks worldwide will collapse within fifty years.<ref>"[http://news.bbc.co.uk/2/hi/science/nature/6108414.stm 'Only 50 years left' for sea fish]", BBC News. 2 November 2006.</ref> In July 2009, [[Boris Worm]] of [[Dalhousie University]], the author of the November 2006 study in ''[[Science (journal)|Science]]'', co-authored an update on the state of the world's fisheries with one of the original study's critics, [[Ray Hilborn]] of the [[University of Washington]] at Seattle.

The [[FAO]] State of World Fisheries and Aquaculture 2004 report estimates that in 2003, of the main fish stocks or groups of resources for which assessment information is available, "approximately one-quarter were [[overexploited]], depleted or recovering from depletion (16%, 7% and 1% respectively) and needed rebuilding."<ref>{{cite web|url=http://www.fao.org/3/y5600e/y5600e05.htm|title=The Status of the Fishing Fleet|publisher=Food and Agriculture Organization|work=The State of World Fisheries and Aquaculture: 2004|archive-url=https://web.archive.org/web/20180119111602/http://www.fao.org/docrep/007/y5600e/y5600e05.htm|archive-date=19 January 2018|url-status=live|access-date=22 May 2020}}</ref>

The [[National Fisheries Institute]], a trade advocacy group representing the United States seafood industry, disagree. They claim that currently observed declines in fish populations are due to natural fluctuations and that enhanced technologies will eventually alleviate whatever impact humanity is having on oceanic life.<ref>[https://www.nbcnews.com/id/wbna15532333 Seafood Could Collapse by 2050, Experts Warn], NBC News.
