Lionfish threatening marine wildlife

Scientists fear the non-native lionfish may be taking over the Caribbean reefs in great numbers.
While native to the Indian and Pacific Oceans, the lionfish is not native to the Caribbean and its presence is multiplying quickly, prompting concerns that they may take over. The lionfish has no natural predators and females can lay 30,000 eggs every four days, on top of this they are also growing larger in the Caribbean than in their native habitat; up to 18 inches in length.
An explosion in the population of the predatory lionfish in Caribbean waters, where it has no natural predators, is posing a widespread threat to marine wildlife.

Kinda makes me wonder why more lionfish aren't caught and sold to saltwater aquarium owners.

How do they taste??? Wonder if we could make it in a good "Meuniere" sauce... or perhaps Lionfish sauce Nantua

I think they're making a mountain out of a mole hill here. Just relax. Nature will sort it out.

No-one knows how lionfish got into the Caribbean. I'm sure they didn't swim all the way from the Pacific / Indian Ocean on its own. Heh.

Well said, all. Some unconscious person introduced Northern Pike to a river fed series of lakes hear in Montana that had an excellent native fishery for trout of all kinds, salmon, etc. The Pike have no natural predators in these waters and now the lakes are empty of most everything except Pike and they are now eating each other. This was done by a "sportsman" who thought Pike fishing was the cat's ass. Goodbye trout and salmon fishing. But this is a relatively closed system, the ocean is not. As to taste, pretty sure they are poison, at least their spines. Doesn't mean they can't be eaten tho... [More]

I don't believe in "invasive" species. If the Lionfish somehow got there and is doing well, that's only nature doing what it does. "Survival of the fittest", as the case may be. And yes, Lionfish are incredibly toxic. Eating them would probably be a bad idea.

You are confusing venomous with poisonous, a Fugu Pufferfish is poisonous and if you eat the wrong part of it, such as the liver, you can die. A Lionfish is venomous and its venom is probably confined to glands at the base of its dorsal fin spines, its flesh should be perfectly safe to eat. It is no different than people eating rattlesnak... [More]
