58-535: Traditional Bhavanarayana Temple is a temple in Bapatla of Bapatla district in the Indian state of Andhra Pradesh . The temple is dedicated to Lord Bhavanarayana and because of this temple the town of Bapatla got its name. It is one of the centrally protected monuments of national importance . The temple was constructed by a Choda king named Krimikantha Chola and was later restored. Bapatla Bapatla

116-448: A body of water (inshore aquaculture), where the cultivated species are subjected to relatively more naturalistic environments; or on fenced/enclosed sections of open water away from the shore (offshore aquaculture), where the species are either cultured in cages, racks or bags and are exposed to more diverse natural conditions such as water currents (such as ocean currents ), diel vertical migration and nutrient cycles . According to

174-600: A blend of ancient structures and modern development, reflecting the evolution of Bapatla over the centuries. The Clock Tower, built in 1948, was demolished for road extension and started to be rebuilt in December 2017. The Suryalanka Beach connected by the Beach Road of the town hosts the Bhavapuri Beach Festival every year. The Edward Coronation Memorial Town Hall was built in 1905 in coronation of

232-469: A growing demand for high-quality protein, encouraged aquaculturists to domesticate other marine species. At the outset of modern aquaculture, many were optimistic that a " Blue Revolution " could take place in aquaculture, just as the Green Revolution of the 20th century had revolutionized agriculture. Although land animals had long been domesticated, most seafood species were still caught from

290-422: A large scale and are most often taken in the wild. In 2016, aquaculture was the source of 96.5 percent by volume of the total 31.2 million tonnes of wild-collected and cultivated aquatic plants combined. Global production of farmed aquatic plants, overwhelmingly dominated by seaweeds, grew in output volume from 13.5 million tonnes in 1995 to just over 30 million tonnes in 2016. Seaweed farming or kelp farming

348-629: A large toll in human lives. Most major human diseases originated in domesticated animals, including diseases such as smallpox and diphtheria , that like most infectious diseases, move to humans from animals. No human pathogens of comparable virulence have yet emerged from marine species. Biological control methods to manage parasites are already being used, such as cleaner fish (e.g. lumpsuckers and wrasse) to control sea lice populations in salmon farming. Models are being used to help with spatial planning and siting of fish farms in order to minimize impact. The decline in wild fish stocks has increased

406-423: A population of 100300 with 98,216 households. The total population constituted 54,385 males and 56,392 females —a sex ratio of 1058 females per 1000 males, higher than the national average of 940 per 1000. 6,182 children were in the age group of 0–6 years, of which 3,156 were boys and 3,026 were girls—a ratio of 959 per 1000. The average literacy rate stood at 80.67% with 52,106 literates, significantly higher than

464-418: A total output which is double that of the rest of the world put together. However, there are some historical issues with the accuracy of China's returns. In 2001, scientists Reg Watson and Daniel Pauly expressed concerns that China was over reporting its catch from wild fisheries in the 1990s. They said that made it appear that the global catch since 1988 was increasing annually by 300,000 tonnes, whereas it

522-468: Is a town and district headquarters of Bapatla district in the Indian state of Andhra Pradesh . It is a municipality and the mandal headquarters of Bapatla mandal of Bapatla revenue division . The nearest towns and cities to Bapatla are Chirala , Ponnur , Tenali and Guntur of 17 km, 22 km, 50 km and 53 km respectively. The name Bapatla is derived from the presiding deity of

580-543: Is an especially important economic activity in China. Between 1980 and 1997, the Chinese Bureau of Fisheries reports, aquaculture harvests grew at an annual rate of 16.7%, jumping from 1.9 million tonnes to nearly 23 million tonnes. In 2005, China accounted for 70% of world production. Aquaculture is also currently one of the fastest-growing areas of food production in the U.S. About 90% of all U.S. shrimp consumption

638-714: Is farmed and imported. In recent years, salmon aquaculture has become a major export in southern Chile, especially in Puerto Montt , Chile's fastest-growing city. A United Nations report titled The State of the World Fisheries and Aquaculture released in May 2014 maintained fisheries and aquaculture support the livelihoods of some 60 million people in Asia and Africa. FAO estimates that in 2016, overall, women accounted for nearly 14 percent of all people directly engaged in

696-758: Is farmed for agar ; the rest are eaten after limited processing. Seaweeds are different from mangroves and seagrasses , as they are photosynthetic algal organisms and are non-flowering. The largest seaweed-producing countries as of 2022 are China (58.62%) and Indonesia (28.6%); followed by South Korea (5.09%) and the Philippines (4.19%). Other notable producers include North Korea (1.6%), Japan (1.15%), Malaysia (0.53%), Zanzibar ( Tanzania , 0.5%), and Chile (0.3%). Seaweed farming has frequently been developed to improve economic conditions and to reduce fishing pressure. The Food and Agriculture Organization (FAO) reported that world production in 2019

754-536: Is generally perceived as benign or even beneficial. Depending on the species and local conditions, bivalve molluscs are either grown on the beach, on longlines, or suspended from rafts and harvested by hand or by dredging. In May 2017 a Belgian consortium installed the first of two trial mussel farms on a wind farm in the North Sea . Abalone farming began in the late 1950s and early 1960s in Japan and China. Since

812-494: Is highly probable that future developments in this field will rely on microorganisms, but greater funding and further research is needed to overcome the lack of knowledge in this field. Microalgae , also referred to as phytoplankton , microphytes , or planktonic algae , constitute the majority of cultivated algae . Macroalgae commonly known as seaweed also have many commercial and industrial uses, but due to their size and specific requirements, they are not easily cultivated on

870-844: Is imparted by government, aided and private schools, under the School Education Department of the state. The mediums of instruction followed by different schools are English and Telugu. The town has many schools, colleges and universities. The Agricultural College was established on 11 July 1945 by Government of Composite Madras State . It is the oldest of all the colleges under Acharya N. G. Ranga Agricultural University . Bapatla Engineering College , College of Agricultural Engineering under Acharya N. G. Ranga Agricultural University, College of Food Science and Technology, Bapatla Polytechnic College, and Bapatla College of Arts & Sciences are other prominent ones. An automatic weather station of India Meteorological Department

928-512: Is located in the town which records the temperatures. BPT 5204 (rice variety of Sona Masuri ), BPT 2270 (Bhavapuri Sannalu) and BPT 2231 (Akshaya) were developed at this rice research unit. There are also a number of research institutes of this agricultural university, such as the AICRP on Betelvine, and a cashew research station. Suryalanka Indian Air Force base on the shore of the Bay of Bengal

986-408: Is located near Bapatla. The base carries out activities such as testing missiles and guided weapon firing range . Aquaculture Aquaculture can also be defined as the breeding, growing, and harvesting of fish and other aquatic plants, also known as farming in water. It is an environmental source of food and commercial products that help to improve healthier habitats and are used to reconstruct

1044-498: Is not easily derived due to lack of data. Another recent issue following the banning in 2008 of organotins by the International Maritime Organization is the need to find environmentally friendly, but still effective, compounds with antifouling effects. Many new natural compounds are discovered every year, but producing them on a large enough scale for commercial purposes is almost impossible. It

1102-588: Is produced in Asia, in particular in China and Thailand. The other 25% is produced mainly in Latin America, where Brazil is the largest producer. Thailand is the largest exporter. Shrimp farming has changed from its traditional, small-scale form in Southeast Asia into a global industry. Technological advances have led to ever higher densities per unit area, and broodstock is shipped worldwide. Virtually all farmed shrimp are penaeids (i.e., shrimp of

1160-462: Is seeded with young abalone from an onshore hatchery. The abalone feed on seaweed that has grown naturally on the habitats, with the ecosystem enrichment of the bay also resulting in growing numbers of dhufish, pink snapper, wrasse, and Samson fish, among other species. Brad Adams, from the company, has emphasised the similarity to wild abalone and the difference from shore-based aquaculture. "We're not aquaculture, we're ranching, because once they're in

1218-492: Is the practice of cultivating and harvesting seaweed . In its simplest form farmers gather from natural beds, while at the other extreme farmers fully control the crop's life cycle . The seven most cultivated taxa are Eucheuma spp., Kappaphycus alvarezii , Gracilaria spp., Saccharina japonica , Undaria pinnatifida , Pyropia spp., and Sargassum fusiforme . Eucheuma and K. alvarezii are attractive for carrageenan (a gelling agent ); Gracilaria

1276-698: The Aquaculture Stewardship Council with the Dutch Sustainable Trade Initiative to manage the global standards and certification programs. After trials in 2012, a commercial "sea ranch" was set up in Flinders Bay , Western Australia, to raise abalone. The ranch is based on an artificial reef made up of 5000 (As of April 2016 ) separate concrete units called abitats (abalone habitats). The 900 kg abitats can host 400 abalone each. The reef

1334-534: The Food and Agriculture Organization (FAO), aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking , feeding , protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated." The reported output from global aquaculture operations in 2019

1392-406: The ecosystem . Some traditional polyculture systems may, in fact, incorporate a greater diversity of species, occupying several niches , as extensive cultures (low intensity, low management) within the same pond. A working IMTA system can result in greater total production based on mutual benefits to the co-cultured species and improved ecosystem health , even if the production of individual species

1450-511: The family Penaeidae ), and just two species of shrimp, the Pacific white shrimp and the giant tiger prawn , account for about 80% of all farmed shrimp. These industrial monocultures are very susceptible to disease, which has decimated shrimp populations across entire regions. Increasing ecological problems, repeated disease outbreaks, and pressure and criticism from both nongovernmental organizations and consumer countries led to changes in

1508-432: The 1980s and 1990s. In 2012, the total world production of fisheries was 158 million tonnes , of which aquaculture contributed 66.6 million tonnes, about 42%. The growth rate of worldwide aquaculture has been sustained and rapid, averaging about 8% per year for over 30 years, while the take from wild fisheries has been essentially flat for the last decade. The aquaculture market reached $ 86 billion in 2009. Aquaculture

1566-940: The Agriculture Ministry's Bureau of Fisheries, as saying that China's figures were "basically correct". However, the FAO accepted there were issues with the reliability of China's statistical returns, and for a period treated data from China, including the aquaculture data, apart from the rest of the world. Mariculture is the cultivation of marine organisms in seawater , variously in sheltered coastal waters ("inshore"), open ocean ("offshore"), and on land ("onshore"). Farmed species include algae (from microalgae (such as phytoplankton ) to macroalgae (such as seaweed ); shellfish (such as shrimp ), lobster , oysters ), and clams , and marine finfish . Channel catfish ( Ictalurus punctatus ), hard clams ( Mercenaria mercenaria ) and Atlantic salmon ( Salmo salar ) are prominent in

1624-678: The Bhavanarayana Temple, which is believed to date back to the Mauryan period. Historically, the town was known as Bhavapuri during the time of the Mauryan Empire, reflecting its connection to the temple and the deity worshipped there. The town has also been referred to as Bhavapattana, Bhavapattu and Bhavapatta. These names were derived from the temple, which was constructed in 1465 by a Chola king named Krimikantha Chola and later restored. Over time, these names evolved into

1682-476: The Caribbean (2%). The contribution of aquaculture to the global production of capture fisheries and aquaculture combined has risen continuously, reaching 46.8 percent in 2016, up from 25.7 percent in 2000. With 5.8 percent annual growth rate during the period 2001–2016, aquaculture continues to grow faster than other major food production sectors, but it no longer has the high annual growth rates experienced in

1740-509: The Legislative Assembly – Vegesana Narendra Varma Aquaculture and agriculture are the main occupations of the coastal areas of the town. Aquaculture involves pisciculture and the farming is dominant with paddy cultivation. The Cairn India have conducted oil drilling onshore of Bapatla which is a part of KG basin stretch. Tourism also plays a role in generating revenue with the presence of Suryalanka Beach near

1798-412: The U.S. mariculture. Mariculture may consist of raising the organisms on or in artificial enclosures such as in floating netted enclosures for salmon, and on racks or in floating cages for oysters. In the case of enclosed salmon, they are fed by the operators; oysters on racks filter feed on naturally available food. Abalone have been farmed on an artificial reef consuming seaweed which grows naturally on

The precipitation is very high with an annual rainfall of about 854 millimetres (34 in) and the month of October receives a maximum rainfall of 197 millimetres (8 in). It is most affected by the cyclonic storms that occur on the east coast. As of 2011 Census of India , the town had

1914-548: The cultivation of ornamental fish . Particular methods include aquaponics and integrated multi-trophic aquaculture , both of which integrate fish farming and aquatic plant farming. The FAO describes aquaculture as one of the industries most directly affected by climate change and its impacts. Some forms of aquaculture have negative impacts on the environment, such as through nutrient pollution or disease transfer to wild populations. Harvest stagnation in wild fisheries and overexploitation of popular marine species, combined with

1972-439: The decade to 2007. Given the long-term importance of agriculture, to date, only 0.08% of known land plant species and 0.0002% of known land animal species have been domesticated, compared with 0.17% of known marine plant species and 0.13% of known marine animal species. Domestication typically involves about a decade of scientific research. Domesticating aquatic species involves fewer risks to humans than do land animals, which took

2030-446: The demand for farmed fish. However, finding alternative sources of protein and oil for fish feed is necessary so the aquaculture industry can grow sustainably; otherwise, it represents a great risk for the over-exploitation of forage fish. Aquaculture production now exceeds capture fishery production and together the relative GDP contribution has ranged from 0.01 to 10%. Singling out aquaculture's relative contribution to GDP, however,

2088-709: The developmental lifecycle of the main species, the giant river prawn . The global annual production of freshwater prawns (excluding crayfish and crabs ) in 2007 was about 460,000 tonnes , exceeding 1.86 billion dollars. Additionally, China produced about 370,000 tonnes of Chinese river crab . In addition astaciculture is the freshwater farming of crayfish (mostly in the US, Australia, and Europe). Aquacultured shellfish include various oyster , mussel , and clam species. These bivalves are filter and/or deposit feeders, which rely on ambient primary production rather than inputs of fish or other feed. As such, shellfish aquaculture

2146-416: The fisheries and aquaculture primary sector. In 2021, global fish production reached 182 million tonnes, with approximately equal amounts coming from capture (91.2 million tonnes) and aquaculture (90.9 million tonnes). Aquaculture has experienced rapid growth in recent decades, increasing almost sevenfold from 1990 to 2021. China overwhelmingly dominates the world in reported aquaculture output, reporting

2204-451: The incorporation of species from different trophic or nutritional levels in the same system. This is one potential distinction from the age-old practice of aquatic polyculture , which could simply be the co-culture of different fish species from the same trophic level. In this case, these organisms may all share the same biological and chemical processes, with few synergistic benefits, which could potentially lead to significant shifts in

2262-487: The industry in the late 1990s and generally stronger regulations. In 1999, governments, industry representatives, and environmental organizations initiated a program aimed at developing and promoting more sustainable farming practices through the Seafood Watch program. Freshwater prawn farming shares many characteristics with, including many problems with, marine shrimp farming. Unique problems are introduced by

2320-415: The industry. Sea ranching involves raising fish in a hatchery for a brief time and then releasing them into marine waters for further development, whereupon the fish are recaptured when they have matured. Commercial shrimp farming began in the 1970s, and production grew steeply thereafter. Global production reached more than 1.6 million tonnes in 2003, worth about US$ 9 billion. About 75% of farmed shrimp

2378-541: The market. In 2009, researchers in Australia managed for the first time to coax southern bluefin tuna to breed in landlocked tanks. Southern bluefin tuna are also caught in the wild and fattened in grow-out sea cages in southern Spencer Gulf , South Australia . A similar process is used in the salmon-farming section of this industry; juveniles are taken from hatcheries and a variety of methods are used to aid them in their maturation. For example, as stated above, some of

2436-550: The mid-1990s, this industry has become increasingly successful. Overfishing and poaching have reduced wild populations to the extent that farmed abalone now supplies most abalone meat. Sustainably farmed molluscs can be certified by Seafood Watch and other organizations, including the World Wildlife Fund (WWF). WWF initiated the "Aquaculture Dialogues" in 2004 to develop measurable and performance-based standards for responsibly farmed seafood. In 2009, WWF co-founded

2494-434: The most important fish species in the industry, salmon, can be grown using a cage system. This is done by having netted cages, preferably in open water that has a strong flow, and feeding the salmon a special food mixture that aids their growth. This process allows for year-round growth of the fish, thus a higher harvest during the correct seasons. An additional method, known sometimes as sea ranching, has also been used within

It oversees the civic needs of the town like, water supply, sewage, and garbage collection. It is a Grade–I municipality which has an extent of 17.92 km (6.92 sq mi) with 34 wards. Kommamuru and Poondla channels of the Krishna Western Delta system provide irrigation water to Bapatla and

2610-530: The population of endangered aquatic species. Technology has increased the growth of fish in coastal marine waters and open oceans due to the increased demand for seafood. Aquaculture can be conducted in completely artificial facilities built on land (onshore aquaculture), as in the case of fish tank , ponds , aquaponics or raceways , where the living conditions rely on human control such as water quality (oxygen), feed, temperature. Alternatively, they can be conducted on well-sheltered shallow waters nearshore of

The town experiences tropical climate with the average annual temperatures records at 28.4 °C (83.1 °F). Hot summers and cool winters are observed due to its proximity to

2726-571: The reef units. Integrated multi-trophic aquaculture (IMTA) is a practice in which the byproducts (wastes) from one species are recycled to become inputs ( fertilizers , food ) for another. Fed aquaculture (for example, fish , shrimp ) is combined with inorganic extractive and organic extractive (for example, shellfish ) aquaculture to create balanced systems for environmental sustainability (biomitigation), economic stability (product diversification and risk reduction) and social acceptability (better management practices). "Multi-trophic" refers to

2784-581: The reported output from global aquaculture operations was over 120 million tonnes valued at US$ 274 billion and by 2022 it had reached 130.9 million tonnes, valued at USD 312.8 billion. For the first time, aquaculture surpassed capture fisheries in aquatic animal production with 94.4 million tonnes, representing 51 percent of the world total and a record 57 percent of the production destined for human consumption. In 2022 most aquaculture workers were in Asia (95%), followed by Africa (3%) and Latin America and

They are separately graphed at the top right of this section, since they do not contribute enough volume to show clearly on the main graph. Commercially harvested echinoderms include sea cucumbers and sea urchins . In China, sea cucumbers are farmed in artificial ponds as large as 400 hectares (1,000 acres). Global fish production peaked at about 171 million tonnes in 2016, with aquaculture representing 47 percent of

3132-527: The wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery . Worldwide, the most important fish species used in fish farming are, in order, carp , salmon , tilapia , and catfish . In the Mediterranean, young bluefin tuna are netted at sea and towed slowly towards the shore. They are then interned in offshore pens (sometimes made from floating HDPE pipe) where they are further grown for

However, there are issues with the reliability of the reported figures. Further, in current aquaculture practice, products from several kilograms of wild fish are used to produce one kilogram of a piscivorous fish like salmon . Plant and insect-based feeds are also being developed to help reduce wild fish been used for aquaculture feed. Particular kinds of aquaculture include fish farming , shrimp farming , oyster farming , mariculture, pisciculture , algaculture (such as seaweed farming ), and
