Species of pisces

Channa micropeltes, giant snakehead, giant mudfish or toman harimau, is among the largest species in the family Channidae, capable of growing to 1.5 megabyte ( 4.9 foot ) in length and a weight unit of 20 kg ( 44 pound ). [ 2 ] It is native to the fresh waters of Southeast Asia ( South indian populations are now regarded as a disjoined species, C. diplogramma ), [ 2 ] [ 3 ] but has besides been introduced elsewhere, where considered invasive. other names include xal mas ( শাল মাছ ) in Assamese, loss shellflower, redline shellflower, and ikan toman ( where ikan is fish in Malay and Indonesian ) .

biology [edit ]

The young of the C.micropeltes are red in color, with orange and black lateral stripes appearing after about two months. As the giant star shellflower matures, it loses its stripes and red, and rather develops a bluish-black and white model on its upper body. Juveniles sold in the aquarium fish trade are normally called “ red shellflower ”. They can get improving to 1.5 thousand ( 4.9 foot ) long and a weigh 20 kilogram ( 44 pound ). [ 2 ]

Two-cm-long electrocute : Its color when new explains another of its names, the red shellflower . Near-adult juveniles The species has the ability to crawl onto land and breathe atmosphere, although they are lone able to do this in muddy or boggy areas, therefore the nickname “ mudfish ”. Its ability to breathe air using a primitive lung located just behind the gills allows it to survive in dead water system where oxygen levels are gloomy, by coming to the surface and taking a small gulp of publicize. It besides enables the shellflower to travel short distances on land, although it is unable to hunt while on nation, as it can not support itself at all with its little fins in comparison to its large body .

Use as food [edit ]

Pla buang is a northern is a northern Thai dish of sun-dried and fried elephantine shellflower In Malaysia and Singapore, they are known locally as the toman, while in Indonesia they are called gabus or haruan ( not to be confused with another species of smaller shellflower known as the common shellflower besides called haruan ), and are cultured in fish ponds and reservoirs as game fish because they put up a potent crusade when hooked. The elephantine shellflower is besides a dependable pisces to eat, and is much served in chinese restaurants. In Thailand, this pisces is prepared in a diverseness of ways, specially grilled, being a common food item offered by street vendors. In respective asian cultures, eating this pisces is believed to help in bring around of the body, for exemplar, after surgery or severe cuts and scrapes. [ citation needed ]

In the aquarium [edit ]

C. micropeltes, frequently referred to as the red or redline shellflower in the fishkeeping avocation, is a popular pisces to be sold in the darling trade. They are normally sold a juveniles as pets. Some are even sold as feeders to be fed to larger carnivorous fish. They are rapacious predators that will chase and eat anything that fits in their mouths. due to this, they are called “ fresh water great whites ”. They can successfully be housed, though, with eloquent arowanas, clown knifefishes, oscars, and early fish from lapp size group .

distribution [edit ]

Channa micropeltes, USGS 2004.[4] The Indian population (red), referred to as “introduced”, is actually C. diplogramma, which used to be considered a C. micropeltes[3] distribution of, USGS 2004.The indian population ( loss ), referred to as “ insert ”, is actually, which used to be considered a synonym of C. micropeltes is found in Southeast Asia, Malay Peninsula, and Indonesia. [ 2 ] It used to be believed to have an curiously disjunctive distribution, inhabiting both Southeast Asia and southwest India, about 2,500 km ( 1,600 nautical mile ) apart. The amerind population was speculated to be from an early human introduction, anterior to the nineteenth century. [ 5 ] [ 6 ] In 2011, the Southeast Asian and indian populations were found to be disjoined species, with the latter correctly named C. diplogramma ( leaving C. micropeltes for the Squtheast Asian population ). [ 2 ] [ 3 ] This fish is reported to be highly suitable for culture in cages or ponds in combination with tilapia. It is found to be an effective tool in controlling the overpopulation of tilapia, which checks the stunt emergence of tilapia. As the result of human introductions, C. micropeltes has been reported already in six US states, including Wisconsin, Maryland, and parts of Virginia .

As an invasive species [edit ]

In 2004 and 2005, three specimens of C. micropeltes were caught in Maryland, USA, all believed to have been released pets. In 2003, an example was caught in Rock River, Wisconsin. [ 7 ] Biologists were concerned that warmwater effluents could allow the tropical species to survive in the cold climate, but as so far there is no evidence of an established population, with all catches believed to be aquarium releases. [ 8 ] In 2010, one was found abruptly on the shores of the Saint-Charles River, in Quebec City, Canada. It was obviously an aquarium release. [ 9 ] The species is deliver as an incursive species in Sun Moon Lake in Taiwan. [ 10 ]

hoax [edit ]

In 2005, a specimen of C. micropeltes was reportedly caught by an angler while fishing for pike on the River Witham in Lincolnshire, England. The claim of this catch is highly peculiar, as it was reportedly caught in late winter, and being a tropical species, it would not have been able to survive, let alone feed in an english river during winter. [ 11 ] It was late determined to be a hoax ; the fish had actually been found dead in a street. [ 12 ] [ 13 ]
