Northern Snakehead Facts

Not all fish look exactly like fish! The invasive Northern Snakehead is injurious wildlife that is known for its tendencies to be an invasive species. Though this fish is native to parts of Asia and Africa, they had been introduced to parts of the United States in places such as Maryland, New York. This has caused great concerns with the Maryland Department of Natural Resources and the U.S Geological Survey, which is concerned about the fish who are in their native range, as opposed to the injurious wildlife that is the Snakehead. They will feed on just about anything such as small birds, many a dead body of a small mammal, all kinds of fish caught in the river mouth, and any other small aquatic creature that can be caught by them. They are speedy swimmers and can travel short distances with ease. They are frequently caught by fishers as other native people on land in an attempt to reduce their population in any American water body.

Each time, these largemouth basses will be seen laying over a thousand buoyant orange-yellow eggs. However, they will lay a lot more eggs at times, up to 50,000 per year. Northern Snakeheads use bits of foliage to build floating nests to shelter their eggs. Parents have been known to threaten those who come too close to their children for several weeks in order to protect them.

Northern Snakehead Fun Facts

What do northern snakeheads look like?

Snakehead the Northern fish, named for their elongated bodies, can grow to be three feet long in introduced areas and even larger in their native range. On their lower jaw, they have sharp teeth, with especially sharp and dangerous canine teeth. Snakeheads are fast swimmers thanks to a long dorsal fin that runs through the middle of their bodies and a powerful anal fin. Scales range in color from golden tan to light brown, with distinct splotches running down their flanks of these species.

Northern snakeheads are fish native to North America.

Juveniles, as well as adults, have almost equal color, which is unusual in snakeheads and can be both cute and terrifying.

How do they communicate?

Northern Snakehead fish can only make a small number of noises. As it feeds and rises to the surface to breathe oxygen, snakehead fish have been heard grunting and clicking. Snakeheads in the north also have excellent vision. These invasive species prefer low-light prey and have been known to target insects and other non-aqueous species outside of water bodies.

Did you know...

The invasive aquatic fish with sharp teeth, a long dorsal fin, and a large mouth are known in the United States. Snakehead fish are named for their long, cylindrical bodies and large scales on their heads, which give them a snakelike look. China, Russia, and Korea are where they originated. Snakeheads can be found in the Potomac River and its tributaries like Virginia and Maryland.

The U.S Fish and Wildlife Service lists all snakehead species as injurious wildlife species. These species are known to consume many freshwater game fish varieties, like the largemouth bass, in the Potomac River system.

This predatory fish can 'breathe air,' which allows them to live on land and in low-oxygen environments. Since northern snakeheads compete for the same resources as native species, they can have a negative effect on their population.

This species' infestations have a small number of possible control methods, which differ depending on the location of the infestation. For large infestations, physical removal of the fish using nets, traps, angling, electrofishing, or biological control is needed. This fish is very common in the Asian fish markets, and most of the introductions were probably made for that purpose. However, the northern snakehead was prohibited from being imported or transported across state lines without a permit from the US Fish and Wildlife Service in 2002.

What is so bad about snakehead fish?

According to a number of U.S Geological Survey scientists, the aggressive Northern Snakehead fish populations discovered in the Mid-Atlantic region are now raising more worry because it could bring diseases further into the area and spread them to indigenous fish and game.

Are northern snakeheads freshwater fish?

These species are a type of freshwater fish whose populations can be found in ponds, lakes, streams, and rivers. Snakeheads' populations, however, are highly resistant to changes in salinity, temperature, and diet, and can thrive in a wide range of environments.
