Save the reef; eat a lionfish

From an article by Jacqui Goddard from The Times (London):

When Hurricane Andrew hit Florida in 1992, no one gave much thought to the six exotic lionfish that spilt into Biscayne Bay as the storm smashed their Miami waterfront aquarium.

Sixteen years later, thousands of the fish are wreaking havoc off America's east coast, leading a potentially catastrophic marine invasion.

The highly poisonous hunter-killer, which is normally found in the Pacific and Indian Oceans, is the first non-native fish to establish itself in the Atlantic, where it is eating its way through other species faster than they can breed.

“They are eating almost anything that fits in their mouths,” said Lad Akins, director of special projects for the Reef Environmental Education Foundation (Reef). There could be, he added, “a severe impact across our entire marine ecosystem”.

With its needle-sharp spines and red and white stripes, the lionfish's hunting prowess is enhanced by the fact that other fish find them so baffling. “They kind of resemble a big clump of seaweed. Native fish don't see them as predators, or even as other fish,” said Mark Hixon, a coral reef ecology expert at Oregon State University. “That allows them to approach other fish and just slurp them up. . . .”

Scientists are looking at why the lionfish is reproducing more rapidly in the Atlantic than in its native waters, hoping to identify a predator to keep numbers in check.

Reef is working on another solution: educating fishermen in how to catch them, and restaurants in how to prepare and serve them. “Lionfish are very edible,” said Mr Akins. “In fact, they are quite delicious.”
