Raipur Fish Hatchery And Training Centre
Raipur Fish Hatchery and Training Centre is a fish hatchery in Raipur Upazila, Lakshmipur District, Bangladesh. One of the six main fish hatcheries in Bangladesh, it was the largest hatchery in the district during the Noakhali Rural Development Project implemented during 1978-1992 by DANIDA, a Danish development agency. One of the three Principal Scientific Officers (PSO) of the Department of Fisheries of Bangladesh governments is assigned to Raipur Hatchery. It also is one of three training centers directly governed by the Director General of the Department, along with Fisheries Training Institute ( Chandpur) and Fisheries Training Academy in (Dhaka). The Raipur Upazila has 8 fish farms, 14 dairy farms, 72 poultry farms and this one hatchery. As of 2004, the government-owned hatchery was able to produce 504 kilograms of hatchlings a year, which mostly consisted of endemic species like ''Catla catla'' (katla), '' Labeo rohita'' (rui), '' Cirrhinus cirrhosus'' (mrigal), '' Labeo ...

Catla Catla
Catla (''Labeo catla''), ( bn, কাতলা, translit=kātlā) 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. In Nepal and neighbouring regions of India, up to Odisha, it is called Bhakura. Catla is a fish with large and broad head, a large protruding lower jaw, and upturned mouth. It has large, greyish scales on its dorsal side and whitish on its belly. It reaches up to in length and in weight. Catla is a surface and midwater feeder. Adults feed on zooplankton using large gill rakers, but young ones on both zooplankton and phytoplankton. Catla attains sexual maturity at an average age of two years and an average weight of 2 kg. Taxonomy The catla was formerly listed as the only species in the genus ''Catla'', but t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing In Bangladesh
Bangladesh being a first line littoral state of the Indian Ocean has a very good source of marine resources in the Bay of Bengal. The country has an exclusive economic zone of , which is 73% of the country's land area. On the other hand, Bangladesh is a small and developing country overloaded with almost unbearable pressure of human population. In the past, people of Bangladesh were mostly dependent upon land-based proteins. But, the continuous process of industrialisation and urbanisation consumes the limited land area. Now there is no other way than to harvest the vast under water protein from the Bay of Bengal, which can meet the country's demand. More than 80 percent of the animal protein in the Bangladeshi diet comes from fish. Fish accounted for 6 percent of GDP in the fiscal year of 1970, nearly 50 percent more than modern industrial manufacturing at that time. Most commercial fishermen are low-caste Hindus who eke out the barest subsistence working under primitive and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Spawning
Artificiality (the state of being artificial or manmade) is the state of being the product of intentional human manufacture, rather than occurring naturally through processes not involving or requiring human activity. Connotations Artificiality often carries with it the implication of being false, counterfeit, or deceptive. The philosopher Aristotle wrote in his ''Rhetoric'': However, artificiality does not necessarily have a negative connotation, as it may also reflect the ability of humans to replicate forms or functions arising in nature, as with an artificial heart or artificial intelligence. Political scientist and artificial intelligence expert Herbert A. Simon observes that "some artificial things are imitations of things in nature, and the imitation may use either the same basic materials as those in the natural object or quite different materials. Herbert A. Simon, ''The Sciences of the Artificial'' (1996), p. 4. Simon distinguishes between the artificial and the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinus Carpio
The Eurasian carp or European carp (''Cyprinus carpio''), widely known as the common carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia.Fishbase''Cyprinus carpio'' Linnaeus, 1758/ref>Arkive The native wild populations are considered Vulnerable species, vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been Domestication, domesticated and Introduced species, introduced (see aquaculture) 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. Taxonomy The two subspecies are: * ''Cyprinus carpio carpio'', native to much of Europe (notably the Danube and Volga rivers)Jian Feng Zhou, Qing Jiang Wu, Yu Zhen Ye & Jin Gou Tong (2003).

Channa Striata
''Channa striata'', the striped snakehead, is a species of snakehead fish. It is also known as the common snakehead, chevron snakehead, or snakehead murrel and generally referred simply as mudfish. It is native to South and Southeast Asia, and has been introduced to some Pacific Islands. Reports from Madagascar and Hawaii are misidentifications of '' C. maculata''.USGS, Southeast Ecological Science Center: Channa striata.' Retrieved 27 June 2014. A genetic study published in 2017 indicates that ''C. striata'' is a species complex. Description It is a bony fish with endoskeleton ribcage, grows up to a meter in length, though because of fishing, this size is rarely found in the wild. It has a widespread range covering southern China, Pakistan, most of India, southern Nepal, Bangladesh, Sri Lanka, and most of Southeast Asia. It has more recently been introduced to the outermost parts of Indonesia, the Philippines, and Mauritius. Reports beginning in the early 20th century that ...

Clarias Batrachus
The walking catfish (''Clarias batrachus'') is a species of freshwater airbreathing catfish native to Southeast Asia. It is named for its ability to "walk" and wiggle across dry land, to find food or suitable environments. While it does not truly walk as most bipeds or quadrupeds do, it has the ability to use its pectoral fins to keep it upright as it makes a wiggling motion with snakelike movements to traverse land. This fish normally lives in slow-moving and often stagnant waters in ponds, swamps, streams, and rivers, as well as in flooded rice paddies, or temporary pools that may dry up. When this happens, its "walking" skill allows the fish to move to other aquatic environments. Considerable taxonomic confusion surrounds this species and it has frequently been confused with other close relatives.Ng, Heok Hee, and Kottelat, Maurice (2008). ''The identity of Clarias batrachus (Linnaeus, 1758), with the designation of a neotype (Teleostei: Clariidae).'' Zoological Journal of t ...

Cirrhinus Cirrhosus
The mrigal carp (''Cirrhinus cirrhosus''), ( bn, মৃগেল, translit=mrigél) 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 . This species and ''Cirrhinus mrigala'' are considered distinct. Aquaculture Mrigal is popular as a food fish and an important aquacultured freshwater species throughout South Asia. It is widely farmed as a component of a polyculture system of three Indian major carps, along with roho labeo and the catla. The introduction to aquaculture across India started in the early 1940s and in the 1950s and in the 1960s to other Asian countries. The mrigal carp fails to breed naturally in ponds, thus induced breeding is done. The Indian carps are considered as a delicacy ...

Labeo Rohita
The rohu, rui, ruhi or roho labeo (''Labeo rohita'') is a species of fish of the carp family, found in rivers in South Asia. It is a large omnivore and extensively used in aquaculture. Description The rohu is a large, silver-colored fish of typical cyprinid shape, with a conspicuously arched head. Adults can reach a maximum weight of and maximum length of , but average around . Distribution and habitat The rohu occurs in rivers throughout much of northern and central and eastern India, Pakistan, Vietnam, Bangladesh, Nepal and Myanmar, and has been introduced into some of the rivers of Peninsular India and Sri Lanka. Ecology The species is an omnivore with specific food preferences at different life stages. During the early stages of its lifecycle, it eats mainly zooplankton, but as it grows, it eats more and more phytoplankton, and as a juvenile or adult is a herbivorous column feeder, eating mainly phytoplankton and submerged vegetation. It has modified, thin hair-l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
