The Northern Snakehead Fish is originally from China, Russia, and North and South Korea. It was introduced because this fish was a popular fish food in the Asian market. Its genus and species is Channa argus. Channa argus can weigh up to 15 pounds (7kg). The snakehead fish scale colors can be from golden tan to pale brown with dark spots on its sides and saddle-like spots on its back. This fish is a freshwater fish and can only tolerate salinity up to ten parts per thousand. Channa argus can breathe out of water, and survive out of water for up to four (4) days if it’s wet. They prefer to live in stagnant or motionless water with mud and water vegetation. They are invasive because they have no predators meaning they are top-level predators. The Northern Snake head fish can affect the populations of their prey because if they over populate then the pond it lives in will lose its biodiversity.
