The bighead carp (Hypophthalmichthys nobilis) is a species of cyprinid freshwater fish native to East Asia, and is one of several Asian carps introduced into North America. It is one of the most intensively exploited fishes in fish farming, with an annual worldwide production of over three million tonnes in 2013, principally from China. [2] Unlike the omnivorous common carp, bighead carp are primarily filter-feeding algae eaters, preferentially consuming zooplankton but also phytoplankton and detritus.
Bighead carp, together with black carp, silver carp, and grass carp, make up the culturally important "four famous domestic fishes" used in polyculture in China for over a thousand years. It is widely farmed for food and chinese medicine. [3]
The bighead carp has a large, scaleless head, a large mouth, and eyes located very low on the head. Adults usually have a mottled silver-gray coloration. It is a large fish; a typical length is 60 cm (2 ft), and maximum observed size of 146 cm (4 ft 9 in) and 40 kg (88 lb). [4]
Bighead carp are native to large rivers and are associated with floodplain lakes of eastern Asia. Their range extends from southern China north to the Amur River system, which forms the border between China and Russia. [5] They have been introduced widely outside their native range, including in the United States, where they are considered invasive [4] as they out-compete native species (e.g. bigmouth buffalo). [6] They are also found in the Nile in North Africa.[ citation needed ]
The bighead carp has a very fast growth rate, which makes it a lucrative and important aquaculture fish, having the fifth-highest production (7.5%) of all cultured freshwater fish worldwide. [2] Its production grew from just 15,306 tonnes in 1950 to 3,059,555 tonnes in 2013, most of the growth being in China. [2]
The value of bighead carp as a food fish has caused it to be exported from its native China to more than 70 other countries, where it has invariably escaped or been intentionally released to the wild. Today, the bighead carp can be found in the wild in Europe, South America and North America. It also has been introduced into most of the Indian subcontinent (India, Pakistan, Bangladesh) and most Southeast Asian countries, as well as to lakes in western China where it is not native. Bighead carp are not always considered undesirable, invasive species where they are introduced outside their native range, and they continue to be stocked in some water bodies to support commercial fisheries. Stocking bighead carp or silver carp usually increases the total biomass of fish available for harvest, but can decrease the catch of native and sometimes more valuable fish. [5]
Bighead carp are considered a highly destructive invasive species in the United States. Bighead carp and the closely related silver carp (H. molitrix) were imported to the United States to remove excess or undesirable plankton, thus improve water quality in sewage treatment plants and aquaculture facilities. However, some fish escaped into the Mississippi River basin, where they are now firmly established. A national plan for the control of Asian carps, Archived 11 August 2020 at the Wayback Machine including bighead carp, was finalized in late 2007.[ citation needed ]
In the United States, a limited consumer market has developed for bighead carp, particularly in ethnic communities, and they are farmed in ponds for this purpose. The live or very freshly killed fish is most lucrative. Because of this, bighead carp are often transported live, and may be a high risk factor for the eventual spread of the fish, either through release by the end purchaser, or through escape during transport. Another potential avenue for unintentional spread of bighead carp is through use as live fishing bait. [5]
Communities are attempting to contain the spread of the extremely invasive bighead carp. New York state has banned the import and possession of live bighead carp, with the exception of New York City, where they still may be legally sold in live food markets (but they must be killed before they leave the premises). Possession of live bighead carp has been illegal in Illinois since 2005. Since February 2007, using live bighead carp as fishing bait has been illegal in Missouri. In December 2010, the U.S. Congress banned the importation of bighead carp. [8]
Live bighead carp are also banned from sale in Canada. Several Greater Toronto Area Asian supermarkets have been fined in the past for selling them. [9] The Ontario Ministry of Natural Resources banned the live sale and importation into Ontario in 2004. Fines are only CAD$3500.00 and have done little to deter the possession of this fish; underground selling continues to happen in several Chinese supermarkets in the region. One live carp was found in Toronto's Don River in 2003. [10]
Killed carp can still be sold in stores, but Asian retailers and consumers prefer live over killed fish. Killed carp is cut into pieces: head, fillet and tail.[ citation needed ]
In Singapore, it is known by the Chinese name 松鱼 (sōng yú). The head of the bighead carp is particularly prized in Singapore, and is usually steamed whole.[ citation needed ]
Although the bighead carp is enjoyed in many parts of the world, it has not become a popular food fish in North America. Acceptance there has been hindered in part by the name "carp", thus popular association with the common carp, which is not a generally favored foodfish in North America. The flesh of the bighead carp is white and firm, and not similar to that of the common carp, which is darker and richer. Bighead carp flesh does share one unfortunate similarity with common carp flesh - both have intramuscular bones within the filet. However, bighead carp captured from the wild in the United States tend to be much larger than common carp, so the intramuscular bones are also larger and less problematic. The Louisiana State University Agricultural Research and Extension Center has a series of videos showing how to prepare the fish and deal with these bones.[ citation needed ]
Although bighead carp reach large size, they are difficult to capture with a rod and reel because of their filter-feeding habits. They may be captured by the "suspension method" used to catch silver carp, or where legal, by snagging with a weighted treble hook through the water. When bowfishing, Bighead carp cannot be shot in the air like silver carp, because they do not jump out of the water when startled by moving boats like the silver carp do. However, they often feed near the surface, where they can be shot by bowfishers, for whom they are popular targets.[ citation needed ]
The term carp is a generic common name for numerous species of freshwater fish from the family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued as both food and ornamental fish in many parts of the Old World, they are considered trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
The common carp, also known as European carp or Eurasian carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia. The native wild populations are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been domesticated and introduced into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family, Cyprinidae.
Asian carp is an informal grouping of several species of cyprinid freshwater fishes native to Eurasia, commonly referring to the four East Asian species silver carp, bighead carp, grass carp and black carp, which were introduced to North America during the 1970s and now regarded as invasive in the United States. These four species, now also known commercially as copi in the United States, are staple food fish in their native China, where they are collectively known as qing cao lian yong (青草鲢鳙) or si da jia yu and are farmed extensively.
The black carp or Chinese black roach is a species of cyprinid freshwater fish and the sole extant species of the genus Mylopharyngodon. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam. One of the largest cyprinids in the world, the black carp has a typical length of 60–120 cm (23.5–47 in), though it can reach up to 1.9 m in length and 109 kg (240 lb) in weight. It is carnivorous and generally feeds on invertebrates such as snails, clams and mussels.
The grass carp is a species of large herbivorous freshwater fish in the family Cyprinidae, native to the Pacific Far East, with a native range stretching from northern Vietnam to the Amur River on the Sino-Russian border. This Asian carp is the only species of the genus Ctenopharyngodon.
Catla, also known as the major South Asian carp, is an economically important South Asian freshwater fish in the carp family Cyprinidae. It is native to rivers and lakes in northern India, Bangladesh, Myanmar, Nepal, and Pakistan, but has also been introduced elsewhere in South Asia and is commonly farmed.
Agriculture and aquaculture in Hong Kong are considered sunset industries. Most agricultural produce is directly imported from the neighbouring mainland China. In 2006 the industry accounts for less than 0.3% of the labour sector. Geographically Hong Kong consists largely of steep, unproductive hillside. The local aquaculture industry is also facing challenges from competition with imported aquatic food products and concern of fish and seafood safety.
Bowfishing is a fishing technique that uses specialized archery equipment to impale and retrieve fish. A bowfisher will use a bow or crossbow to shoot fish through the water surface with a barbed arrow tethered to a line, and then manually retrieve the line and arrow back, in modern times usually with a reel mounted on the bow. Unlike other popular forms of fishing where baiting and exploiting the fish's instinctual behaviors are important, bowfishing is similar to spearfishing and relies purely on the fisherman's own visual perception and marksmanship, and usually do not involve using other tools such as hand net.
The bigmouth buffalo is a fish native to North America that is in decline. It is the largest North American species in the Catostomidae or "sucker" family, and is one of the longest-lived and latest-maturing freshwater fishes, capable of living 127 years and reproducing infrequently. Even at a century old they show no age-related declines, but instead improvements relative to younger individuals, making this species a biological marvel. It is commonly called the gourdhead, marblehead, redmouth buffalo, buffalofish, bernard buffalo, roundhead, or brown buffalo. The bigmouth buffalo is not a carp, nor is any other fish in the sucker family. Although they share the same order, each belong to different suborders and are native to separate continents.
The silver carp or silverfin is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia, from the Amur River drainage in the north to the Xi Jiang River drainage in the south. Although a threatened species in its natural habitat, it has long been cultivated in China as one of the "Four Famous Domestic Fish" (四大家鱼) together with Bighead carp, Black carp and Grass carp. By weight, more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other shark species.
Hypophthalmichthys is a genus of large cyprinid fish consisting of three species. The name comes from Greek ὑπό, ὀφθαλμός, and ἰχθῦς, thus 'fish with eyes below', referring to the fact that the fish has its eyes below the mouth line. Members of this genus are native to fresh water in East Asia, ranging from Siberia to Vietnam, but have been widely introduced outside their native range, where often considered invasive. Big head and silver carps have been reaching the Illinois River system outside of Lake Michigan but have grown concerns of them likely being established in the Great Lakes. The reason is that stakeholders, such as fisheries, recreationists, and the fishing industry can be impacted economically and potentially decrease biodiversity or even extinction of these or other species. Environmental DNA has been used to monitor these species and look for positive eDNA detections and the presence of live organisms. The genus is also known as Bighead carp, though that term is also used for individual species, particularly Hypophthalmichthys nobilis. The Russian language has a special word for the genus - tolstolób(ik).
Rough fish is a term used by some United States state agencies and anglers to describe fish that are less desirable to sport anglers within a defined region. The term usually refers to larger game fish species that are not commonly eaten, are too rare to be commonly encountered, or are not favorably sought by anglers for sporting purposes. Many of these species are actually very important in the commercial fishing industry, where they make up the bulk of commercial food fish catches in inland freshwater bodies.
The fishing industry in the land-locked country of Laos is a major source of sustenance and food security to its people dwelling near rivers, reservoirs and ponds. Apart from wild capture fisheries, which is a major component of fish production, aquaculture and stocking are significant developments in the country. Historically, fishing activity was recorded in writings on the gate and walls of the Wat Xieng Thong in Luang Prabang dated 1560. For many Laotians, freshwater fish are the principal source of protein. The percentage of people involved in regular fishing activity is very small, only near major rivers or reservoirs, as for most of the fishers it is a part-time activity.
China has one-fifth of the world's population and accounts for one-third of the world's reported fish production as well as two-thirds of the world's reported aquaculture production. It is also a major importer of seafood and the country's seafood market is estimated to grow to a market size worth US$53.5 Billion by 2027.
China, with one-fifth of the world's population, accounts for two-thirds of the world's reported aquaculture production.
The mrigal carp, also known as the white carp, is a species of ray-finned fish in the carp family. Native to streams and rivers in India, the only surviving wild population is in the Cauvery River, leading to its IUCN rating as vulnerable. It is widely aquafarmed, and introduced populations exist outside its native range. It reaches a maximum length of 1 m (3.3 ft). This species and Cirrhinus mrigala are considered distinct.
Cirrhinus molitorella is a species of ray-finned fish in the genus Cirrhinus found mainly in southern China and Vietnam.
The Chinese Academy of Fishery Sciences (CAFS) is a large fisheries research institute. It was founded in 1978 under the Ministry of Agriculture in the People's Republic of China. It is a leading research institution in China, active in almost all research areas to do with aquaculture and marine and freshwater fisheries.
Asian carp, a group of invasive species of fish introduced into North America, pose a major threat to the ecology, environment, economy, and way of life in the Upper Midwest and Great Lakes region of the United States and Canada. The term refers to a group of cyprinid fish species originally native to East Asia, of which include several are known to be invasive in the United States, and represent the most urgent potential danger to the ecology of the Great Lakes.
