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.[3][4]curry made with this fish and tapioca is a delicacy in Kerala. In Indonesia, common snakeheads are a popular type of salted fishes in Indonesian cuisine. In the Philippines, they are commonly served either fried, grilled, paksiw (poached in a water-vinegar mix), or with soup (commonly cooked with rice washing).
Dishes using this fish eaten with rice is very popular among Bengalis of Bangladesh and West Bengal. The fish is also an esteemed delicacy in other parts of India, including Andhra Pradesh, Tamilnadu and Kerala.
Common snakeheads are very popular in Thai cuisine, where they are prepared in a variety of ways. Grilled fish is a common food item offered by street vendors or in kaeng som. Pla ra, a fermented fish sauce popular in northeastern Thai cuisine, is made by pickling common snakehead and keeping it for some time. Also, a Chinese sausage is prepared with common snakehead flesh in Thailand.[12]
Immune system Edit

Worldwide inland fish culture industry is suffering from massive economic losses due to epizootic ulcerative syndrome (EUS) and fish-based pathogens. The available literature indicate that infection from fish pathogens like bacteria (Aeromonas hydrophila and Aeromonas sobria), fungi (Aphanomyces invadans) and viruses can cause stunted growth and severe mortality in the C. striatus. Channa striatus rely on their innate immune components to fight against these infections. Some of the immune molecules that have been characterized in Channa striatus includes Chemokine, Chemokine receptors, Thioredoxin, Superoxide dismutase, Serine ജലാശയങ്ങളിൽ സാധാരണ കണ്ടു വരുന്ന ഒരു മത്സ്യമാണ് വരാൽ. ശാസ്ത്രനാമം:Channa striata. ബ്രാൽ, വ്രാൽ, കണ്ണൻ, കൈച്ചിൽ എന്നിങ്ങനെ പ്രാദേശികമായി അറിയപ്പെടുന്നു. ഇംഗ്ലീഷിൽ -chevron snakehead, striped murrel എന്നീ പേരുകളുണ്ട്. മൂന്ന് കിലോയോളം വലുതാകുന്നതാണ് ഈ മത്സ്യം.

The bullseye snakehead (C. marulius) is native to a wide range of countries in southern Asia and India and has been introduced to Broward County in Florida, USA (Howells, 2004). It is entirely absent from Indonesia and Malaysia and may have been replaced by C. maruloides. C. marulius, one of the largest species of snakeheads (Bardach et al., 1972), prefers deep, clear lakes and rivers with firm sand or rocky substrate. As C. marulius constructs nests of vegetation for spawning and rearing of young, the species is often found in association with flooded forests and submerged vegetation (Talwar and Jhingran, 1992). C. marulius is aggressive and highly predatory and is known to prey upon fishes (including conspecifics), crustaceans and insects (Dasgupta, 2000). They are highly sought after as a game species in Thailand and are known from both the aquarium and live food fish industries (Courtenay and Williams, 2004).
Following the introduction of the species into the USA, likely as a result of intentional public release via the aquarium or live food fish trade, significant concern exists regarding further invasion into non-native waterbodies and the resulting impacts to native biotic communities. Trophic collapse, extirpation of native species and significant risk to humans are all potential consequences of an invasion by C. marulius. The species also has the potential to successfully disperse between waterbodies as a result of a respiratory adaptation which allows it to breathe air from the atmosphere and enables the species to be independent of an aquatic environment for lengths of time. Additionally, its long, serpentine body form provides the opportunity for C. marulius to 'wiggle' and disperse overland between waterbodies not connected by aquatic channels, further increasing its potential for invasiveness.
Federal legislation exists in the United States to prevent the importation and transportation of all members of the family Channidae (the snakeheads) between the continental USA and its territories (Hoffman, 2002). The species is listed by the US Fish and Wildlife Service on the federally regulated list of injurious fishes. At present, no federal or provincial legislation exists in Canada regarding the importation, transportation or possession of snakehead fishes.
