From researching around a bit, it seems that these live pretty deep. "Normal" habitat for lionfish is defined as between 100' and 300'.

One must get lost once in a while and venture up to the 50'-100' reefs where we can see them. If the masses of them live beyond normal rec diving limits it will be impossible to get rid of them.

A regular cleansing of the ones that take up residence on the shallower reefs would likely be the only possible course of action.

I guess they are good to eat, so that in itself will help in eradication because they are slow and fairly easy to catch...with the exception of needing to stay away from the spines.
 
The lionfish is one of the most venomous fish on the ocean bottom floor. Lionfish have venomous dorsal spines that are used purely for defense. When threatened, the fish often faces its attacker in a head-down posture which brings its spines to bear. However, a lionfish's sting is usually not fatal to humans. If a human is envenomed, that person will experience extreme pain, and possibly headaches, vomiting, and breathing difficulties. A common treatment is soaking the afflicted area in hot water, as very few hospitals carry specific treatments. However, immediate emergency medical treatment is still advised, as some people are more susceptible to the venom than others.
 
Sorry for my ignorance, but I assume lionfish are not native to cozumel. How did they get there? Why is it important to kill them? I'll try to google them to learn more. What is the other fish that looks like a clump of seaweed on the bottom? a scorpionfish?

I noticed that too because I was reading up on the lionfish on Wikipedia too. Where would we be with out Wikipedia.

I have this discussion with my wife all the time, except that it's "Remember what it was like before we had the internet?" We can find the answers to important questions like "Who was it that recorded that song 'MTA' back in the 60's?" (It was the Kingston Trio, and it was actually in 1959, but the song was actually written by Jacqueline Steiner and Bess Lomax Hawkes in 1948 and it was originally called "Charley on the MTA") Wow. We would have probably argued about that for weeks before the advent of the internet, but now we can settle arguments in seconds. Hi ho Google, awaaaaaayyy...
 
I think that folks need to act before the numbers get out of hand. It would be great if the Marine Park, or interested stakeholders in the Cozumel reefs, such as dive ops, fishermen, and the fishing charter ops, got together and offered a bounty.

WANTED -- Dead or Alive, Lionfish, etc.

If the numbers are kept small a decent size bounty would be practical, and the profit motive could be enlisted to do to lionfish what it's done to other species. The price of shark fins has led to a reduction in the population of sharks by almost 90%. On second thought, maybe we can start a small epicurean movement and convince the Chinese that Lionfish are a rare and unique delicacy.

One thing that everyone should keep in mind, is that it isn't only about reduced populations of pretty fish making diving not as nice. By overconsumption of juveniles, lionfish will ultimately reduce the populations of food and game fish throughout the Caribbean and Western Atlantic, placing greater stress on already threatened species, and food stocks.

Question-- since even the most aggresive human intervention program will probably only be effective between 15 and 100 feet of depth, do lionfish also thrive at greater depths? If so, it'll be impossible to ever get the genie back in the bottle.
