Choita River
The Choita River ( bn, বাংলায়: চৈতা নদী) flows west and south of Kharua Rajapur. Choita River is a branch of Ichamati river. Choita River debouches into the Jamuna River in Gaighata. The length of the river is 40 km. The river is currently separated from the Ichamati river at the debouch and the river has lost its normal flow speed due to flooding. A wetland to the east side of village had been transformed into productive farmland. Agriculture made wealth, and wealth made Kharua Rajapur areas. Fish embankments are being constructed and fish are being cultivated by splitting the river bed, blocking the river flow. During summer, fish food is available in the river. A crocodile jaw was found at Kinarmath village while excavating this river. Farmers grow crops which they export to other states and many villagers travel to work outside the area. So fertile is the soil here that anyone who owns just a few acres can earn a decent living. Villagers grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kai Stingaree
The Kai stingaree (''Urolophus kaianus'') is a species of stingray in the family Urolophidae, known only from two juveniles collected from deep in the Kai Islands of eastern Indonesia. This species has a rhomboid pectoral fin with a very blunt, rounded snout, and a tail with lateral skin folds, a leaf-shaped caudal fin, and no dorsal fin. It is brown above with blackish coloring on the upper surface of each eyeball. The larger of the two specimens measures long. The International Union for Conservation of Nature (IUCN) does not yet have enough information to assess the Kai stingaree beyond Data Deficient. It presently faces little fishing, though this is liable to change in the future. Taxonomy From September 9 to 29, 1874, the research ship HMS ''Challenger'' collected a number of hitherto-unknown fishes from Station 192 in the Kai Islands, including two specimens of the Kai stingaree. British zoologist Albert Günther wrote a brief description of the new species and publis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Cormorant
The little cormorant (''Microcarbo niger'') is a member of the cormorant family of seabirds. Slightly smaller than the Indian cormorant it lacks a peaked head and has a shorter beak. It is widely distributed across the Indian Subcontinent and extends east to Java, where it is sometimes called the Javanese cormorant. It forages singly or sometimes in loose groups in lowland freshwater bodies, including small ponds, large lakes, streams and sometimes coastal estuaries. Like other cormorants, it is often found perched on a waterside rock with its wings spread out after coming out of the water. The entire body is black in the breeding season but the plumage is brownish, and the throat has a small whitish patch in the non-breeding season. These birds breed gregariously in trees, often joining other waterbirds at heronries. Description The little cormorant is about long and only slightly smaller than the Indian cormorant (''Phalacrocorax fuscicollis''). The Indian cormorant has a n ...

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and ''Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Asian Swamp Eel
The Asian swamp eel (''Monopterus albus''), also known as rice eel, ricefield eel, or rice paddy eel, is a commercially important, air-breathing species of fish in the family Synbranchidae. It occurs in East and Southeast Asia, where it is a very common foodstuff sold throughout the region. It has been introduced to two areas near the Everglades in Florida and near Atlanta in Georgia. Taxonomy The Asian swamp eel is a freshwater, eel-like fish belonging to the family Synbranchidae (swamp eels).Nelson, J.S. Fishes of the World. 3rd. New York City: John Wiley & Sons, Inc., 1994. Print. Some work indicates that the species should be split into three geographical clades or cryptic species, although these were not given nomenclatural names, as the taxonomic synonymy was too complex to sort out at the time. The populations in the Ryukyus are distinct, the populations in China and Japan belong to another clade, and the rest, the original ''M. albus'', belong to the third group. Althoug ...

Mrigal
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 ...

Walking Catfish
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 th ...

Ichamati River
Ichamati River ( bn, ইছামতী নদী) (also spelt Ichhamati), is a trans-boundary river which flows through India and Bangladesh and also forms the boundary between the two countries. The river is facing the problem of siltation leading to thin flow of water in the dry season and floods in the rainy season. Experts are handling the situation and remedial matters are being discussed between the governments of India and Bangladesh. Ichamati flow Ichamati River is now in three parts: (1) The longer part flows from the Mathabhanga River, a distributary of the Padma, and after flowing for joins the Kalindi River near Hasnabad in North 24 Parganas and Debhata in Satkhira District. (2) Once the main river west of Dhaka and (3) Ichamati of Dinajpur. Rennel's map of 1764–66, shows the last two rivers as one. The second river marked above originates south of Jafarganj opposite to the mouth of the Hoorsagar near Nathpur factory and runs towards Joginighat in Munshigan ...
