mid term mc questions __**General information**__ The northern snakeheads scientific name is Channa argus, ChannidaeGerman: Amur-Schlangenkopf; Chinese: Hey yu; Japanese: Kamuruchi; Russian: Zmeegolov. The snakehead has a Snake like head, canine like teeth, eye above the middle part of the upper jaw; Coloration is a golden tan to pale brown, with dark blotches on the sides and saddle-like blotches across the back. Villiform teeth in bands, large canine on the lower jaw and palatines, length up to 40 inches (1.0 m), with one report of 60 inches, weight up to 15 pounds. Northern snakeheads were 1st confirmed in Pennsylvania in July 2004 after an angler caught and preserved two from the 17-acre Meadow Lake in Philadelphia County, and are Native to china Russia and Korea. __** Detailed description **__ The northern snakehead spawns usually in early morning from spring to summer, Male and female build donut-shaped nest about 39.4 in (100 cm) in diameter using aquatic plant debris. Female deposits an average of 7,300 eggs 0.06–0.08 in (0.15–0.2 cm) in diameter; incubation takes about 45 hours at 77°F (25°C). Guarded and cared for by the parents, newly hatched fry are all black, and leave the nest when they reach 0.03 in (0.8 cm), at which size the body has become yellowish. The northern snakehead feeds on fishes, frogs, prawns, worms, crayfishes, and juvenile water birds. Northern snakeheads are a predatory fish and will compete with other fish species for forage and habitat. It is too early to say what impact the presence of snakeheads will have on other species already in Meadow Lake and other waters. __**The northern snakehead is from Central China (Yangtze to Luan River basins) including Korea to the Amur River basin, southern Russia; introduced and established in Japan, the United States, and republics in the former Soviet Union adjacent to Caspian Sea. The northern snakehead spreads easily in Lakes, swamps, marshes, reservoirs, and rivers in slow-moving to stagnant temperate waters. __**The northern snakeheads impact on the area it invades is catastrophic because it is such an amazing competitor that it beats out most if not all the other fish in the area it has invaded. There for it coming into an area that it is not native is a negative. **__Control measures__**  Control measures have been taken, in some areas the have specific teams or groups that fish for northern snakeheads. They are advised not to be released back into the water and do not just throw on land for they can live out of the water for a long period. http://www.youtube.com/watch?v=MA8sXHNjazs
