New York DEC expands investigation after invasive northern snakehead fish found in Suffolk County pond for the first time
The fish has the potential to reduce or even eliminate native fish populations and alter aquatic communities, according to the state.

For the first time, the northern snakehead fish has been spotted in Lily Pond in Lake Ronkonkoma, prompting the New York State Department of Environmental Conservation to expand its investigation into the dangerous, invasive species today.
Later this morning, crews will head out into the water to survey the pond.
Northern snakeheads are a predatory fish native to Asia that were most likely introduced to New York through aquarium dumpings, as well as both accidental and intentional releases from fish markets.
The species prefer to live in stagnant shallow ponds or swamps and can spread to nearby waterways on their own because they can breathe air and survive for days out of water.
Wildlife experts said they have the potential to reduce or even eliminate native fish populations and alter aquatic communities.
The DEC said it's crucial to stop the spread of the invasive predator to protect the health of Long Island's waters, wildlife and fishing industry.
Part of today's efforts will include crews electrofishing to determine if there are additional invasive fish in the water.
This is a non-lethal technique that involves introducing an electrical current into the water. The current causes a muscle contraction in the fish, temporarily stunning them, so they're slowed down and easier to catch. Officials said the fish are not injured in the process.
