Dangerous Invasive Northern Snakehead Found in Louisiana – What You Need to Know

BATON ROUGE, La. (KPEL News) - The Louisiana Department of Wildlife and Fisheries (LDWF) is warning anglers about a newly discovered threat to the state’s waterways—the invasive Northern Snakehead fish. Found recently in Concordia Parish, this predatory species poses a risk to Louisiana’s native fish populations and ecosystems.

What is the Northern Snakehead?

Native to Asia, the Northern Snakehead is an aggressive predator that feeds primarily on fish but will also consume frogs, crawfish, and other small aquatic animals. The species closely resembles Louisiana’s native Bowfin (Choupique), but there are a few key differences:

• Extended anal fin – Runs along much of the fish’s underside.
• Protruding lower jaw – Sticks out past the upper jaw.
• No black spot – Unlike the Bowfin, the Snakehead lacks a black spot at the base of its tail.
• Snake-like scales – Enlarged scales on its head, giving it a reptilian appearance.

These fish can grow up to three feet long and are known for their resilience, including the ability to breathe air and survive in low-oxygen waters.

How Did It Get to Louisiana?

According to LDWF, the Northern Snakehead likely made its way into Louisiana waters from neighboring states such as Mississippi and Arkansas. The species has been reported in 11 other states and was initially introduced in the U.S. through the aquarium trade and live fish markets.

While LDWF officials do not expect Snakeheads to cause immediate ecological devastation—unlike invasive carp, which reproduce rapidly—they are monitoring the situation closely.

"Snakeheads could potentially get a foothold in our state, but we do not expect them to have major impacts on our native fish," said LDWF’s Aquatic Nuisance Species Coordinator, Robert Bourgeois. "In other states where snakeheads are already present, there has not been major impact on native fish. Unlike invasive carp, they are slower at reproducing."

What Should You Do if You Catch One?

If you believe you’ve caught a Northern Snakehead, DO NOT RELEASE IT BACK INTO THE WATER. Instead, LDWF advises taking the following steps:

1. Take a side-view photo of the fish for identification.
2. Kill the fish immediately.
3. Double-bag it and freeze it if possible.
4. Note the exact location of the catch.
5. Report it to LDWF by calling the Aquatic Invasive Species Hotline at (225) 765-3977 or emailing AquaticInvasives@la.gov.

Can You Eat It?

Yes. If you catch a Northern Snakehead, it is safe to eat. In some parts of the world, the fish is considered a delicacy.

Why Does This Matter?

Louisiana’s waterways support a thriving recreational and commercial fishing industry, and any disruption to the natural ecosystem could have long-term consequences. The Northern Snakehead is a formidable predator that could outcompete native fish for resources, potentially affecting local fish populations and disrupting the balance of aquatic ecosystems.

It is also illegal to possess, sell, or transport live Northern Snakeheads in Louisiana, meaning that even the unintentional release of this species could have serious consequences.

Protecting Louisiana’s Waters

With Louisiana’s unique and diverse aquatic environment, preventing the spread of invasive species is crucial. LDWF urges all anglers and outdoor enthusiasts to be vigilant, report any sightings, and follow regulations to keep Louisiana’s fisheries healthy.
