I realize the inherent problems with introduction of a non-native species but would it not be a possibility in this case if an egg predator for lionfish was identified in the Pacific?
Hi Jim, my understanding is that scientists do believe there is egg predation in the Pacific probably by birds and others, but it has never been fully studied. Yes you can use it just give credit to the website.
It was written by Scott Harrell about 5 years ago. I am part of a pioneering group out of Belize where the populations of LF have exploded in the last 5 years. I am developing trainings to assist in the education of this invasive species.
Visual aids are always a plus. I am trying to find information on how many lionfish fry survive … I know they can reproduce every 4 days and up to 30, eggs but I want to create a visual of the approximate percentage of fry that survive from a spawning.
I have not found anything on that. You might try contacting Dr. Good job where do I get certified? Retired so I am on a limited income. Trips to carib are expensive. Great diving with you Scott. Maybe next year again. I certainly hope to see you next year if you and I are both able! Electro-fishing works great in fresh water but not so well in salt water. As current takes the path of the least amount of resistance, saltwater is very conductive and is a better conductor than the fish, allowing the current to bypass the fish.
In regards to hunting lion fish, once you have speared it and wish to leave it for other fish is it necessary to cut the spines off the lion fish for other fish to consume it or have other fish seemed to have figured out a way around the spines when eating them? I know this is an older article, but some friends of mine have been spearing lionfish since they are taking over everything!
I have lionfish from past one year in my aquarium and were doing good by eating black mollies but recently started feeling them freezed shrimp and they used to like it but from reasons unknown they stopped eating from past five days so can u help me out in this matter meant what steps should i take to caax them to eat in order for there survival. We are all about hunting and eating the invasive lionfish in the Atlantic, not keeping them in aquariums.
Introducing other predators is always fraught with the potential of unintended consequences. Mongoose were introduced to Hawaiian and Caribbean Islands to control the rat populations on sugar cane plantations, and today the mongoose itself threatens many native species in those places.
I was wondering if scientists have tried species of native moray eels to eat these fish. I do know that these eels are very aggressive and can get quite large. Also, species of the moray eel is found in the Caribbean. Would this be a logical solution. Yes, the Caribbean Morey eels love to eat wounded lionfish. Thank you! The recruitment of coral-reef fishes was studied during the recruitment period July-August on small patch reefs in the Bahamas with and without lionfish.
Over the five week period, net recruitment i. Hi Shea, the spines can be thrown away. Just sitting at room temperature will neutralize the venom in minutes. How come lionfish are a bigger problem in the Atlantic and not the Pacific? Why are they not a huge problem in the Pacific? They can live and reproduce in any depth. However, if you keep them on ice they can still sting you hours or even days later. Studies have found tagged lionfish usually within a few hundred meters of where they are tagged even months later.
How long do lionfish live? I had one in an aquarium for a number of years before he died. I fed it feeder goldfish and frozen shrimp. Maybe a parasite from the goldfish killed it. Just a thought!
I think they can live around years, maybe a little more. Also, out of curiosity, where does your interest in lionfish spur from? My interest in lionfish spurs from them being really fun to hunt while scuba diving. Keep on the good work Dr. I need to cite a scientific journal source where it talks about the predators of the lionfish in its native Indo-Pacific habitat ex: sharks eels, grouper, cornetfish, frogfish, scorpionfish.

Lionfish FAQ The following questions are the most frequently asked about the non-native, invasive lionfish. Why are lionfish so bad? Are lionfish a problem? Where are lionfish originally from? Where do lionfish come from? When did lionfish get here in the Western Hemisphere?
Wintertime ocean temperatures seem to be the only limiting factor of their distribution as it is believed that lionfish are unable to survive water temperatures below approximately 50 degrees Fahrenheit or 10 degrees Celsius Do lionfish have natural predators in the Indo-Pacific Oceans and Red Sea? What is being done to control lionfish? What can be done about lionfish? Can we train other native fish to eat lionfish?
Are lionfish dangerous to humans? Do lionfish attack people? Are lionfish poisonous or venomous? Where are the venomous spines? How many dangerous spines does a lionfish have? Lionfish have cycloid scales fish scales that are oval or elliptical in shape with a smooth edge.
A large group of invasive lionfish near St. Thomas, U. Virgin Islands, filmed during a Caribbean coral reef mapping expedition in April, During the Caribbean mapping expedition, lionfish were spotted during a total of 26 dives. Lionfish were spotted as deep as feet. Learn more about this mission. In between, the species is found throughout Micronesia. The cycloid scales of lionfish. In this type of scale, the anterior part of each scale is usually overlapped by the posterior portion of the scale in front of it, giving the fish greater flexibility than fishes with other types of scales.
There are four main kinds of scales placoid, cosmoid, cycloid and ctenoid, and ganoid, and numerous variations of each kind. Lionfish are a popular marine ornamental fish and were possibly intentionally released into the Atlantic. The first lionfish was reported in South Florida waters in with many additional sightings occurring until they were documented as established in the early s.
Habitat: Lionfish are found in mostly all marine habitat types found in warm marine waters of the tropics. Lionfish have been found in water depths from 1 to feet on hard bottom, mangrove, seagrass, coral, and artificial reefs like shipwrecks.
Ecological Role: Lionfish are slow-moving and conspicuous, so they must rely on their unusual coloration and fins to discourage would-be predators from eating them.
