Lion Fish Woes!
The Marine Park had a big get-together last night to educate the divers and hopefully solve our lion fish problem. In the end, the truth is the lion fish is here to stay and here is why.
It's a damn durable fish. These things grow at a very fast rate and can be sexually mature in 6 months. They can survive for more than 4 months without eating anything and can thrive in almost any warm water environment. Reported sightings of lion fish are as deep as 500 ft. This is a tough fish! When food is good, they are voracious predators and will eat anything they can wrap their big mouths around. This is why they are so dangerous for our ecosystems.
The good news is they have behaviors which make them pretty easy to catch and kill. They are very territorial so you can find them in the same place day after day. They move pretty slowly and are not afraid of anything. They won't go run and hide when they see divers. If you want to catch them, they pretty much cooperate and let themselves be netted. Trouble is as divers, we must be very careful of their venomous spines. They have 13 on the top and 7 on the bottom of the fish and each one can stick a very painful bit of venom that can last for hours. If stuck heat is the key to break down the poison quickly.
The conference was given by REEF from the US. They have been studying this fish since its introduction in Florida in 1994. The presenter (Lad Akins) was very knowledgeable and did a good job of educating the more than 50 divers that came to help. He showed us how to capture them, how to avoid their sting and why we need to do something now. So far the lion fish has invaded much of the Caribbean and Atlantic seaboard. The only thing that seems to stop them is cold water. They seem to make it as far as Maine but don't survive the winter months. In the Bahamas they have devastated the native species and will likely do the same here if they get a chance. In the first areas they basically did nothing and let nature take its course. Cozumel is in the position to see if this constant vigil and kill method can slow the lion fish invasion and keep Cozumel's reefs in relative harmony.
So the plan is to capture and kill each fish we encounter. So far Cozumel has captured about 60 fish. This has a chance of working well in the areas where the divers frequent but on the East side of the island they will thrive. They can also live very well at depths deeper than we can go.
So our work is cut out for us and hopefully with the help of REEF, the Marnie Park and all the divers on our reefs we can maintain some control over this amazing fish. You have to respect a fish that is so hearty and well adapted. Too bad we have to kill it too.

Spot tracking
One of the new things that you will see on the blog is a tracking device called a spot.
http://findmespot.com/barf/
This device will allow me to be tracked every 10 min and will hopefully keep the story more interesting and fun! the map feature will look like this one :
http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0zJt7xhiqZ8oClqMteLDVWR1hrAA0k0NN
I would be interested in your feedback as to this part of the trip and the blog entries. There will actually be a map on each blog entry with my actual location. Even if the blog was updated a day or two before when I found and internet connection the SPOT device should show my current location.
Would love to hear your comments on it!
Have a great day!

The Invasion
Many of you may have heard about the lionfish that have been mysteriously arriving in
Wikipedia says:
The lionfish is native to the tropical Indo-Pacific region of the world, but various species can be found worldwide. Due to a recent introduction, the lionfish has recently been spotted in the warmer coral regions of the Eastern Atlantic Ocean and Caribbean Sea.[2] This introduction was most likely caused when a hurricane destroyed an aquarium in southern Florida. DNA from captured lionfish in this region shows that they all originated from the same six or seven fish.
SO guess what? They are in Cozumel and the
So do we kill it or do we love it?
2 days ago I had my first encounter and in my mind I am still torn with the decision.
When last we met our intrepid adventurers (I always wanted to write that) they are happily enjoying an afternoon swim on
Katherine (Marty’s wife) is just ahead of me and points out something interesting. I pop down to 83 ft and she points to a flowing black fish on the edge of the wall. Sure enough the arch enemy of the
When I get to the surface, Carlos is there and he throws me my mask box so I have something to capture said invader there in. On return to the scene of the crime, the bold and unflinching predator is in exactly the same place as when we arrived, basking in the glory that is his own, his ocean, we are just visiting and he knows it. Unfortunately, the marine park feels differently. I know my job as guardian of the marine park is to subdue such vile and dangerous predators and deliver them forthwith to marine park jail.
So I arrive on scene with plastic mask box in hand and attempt to herd the bold but deadly lionfish into captivity. Once again he has other ideas on the matter. It seems he does not want to go inside? He darts around escaping each time. This puzzles 10-year-old Margo, who has been watching the whole event. She thinks the ecologically minded, super green diver guy ScubaTony said “don’t take anything, don’t touch anything inside the marine park”. And she would be correct. I did say that and do say that all the time. Meanwhile back at the ranch (always wanted to say that too), the brave lionfish has decided bold is no longer working for him and he now hides deep inside the reef so that no mask box or ecologically minded, super green diver guy will take him away to marine park jail. I give up and continue the dive with my guests, a couple of which have used up a lot of their air at 83 ft. Lion fish 1, Scubatony zippo!
Next day is Monday and I have a couple other divers onboard. The
We get him back to the boat and Carlos puts him in a bucket of water for the journey back to Caleta. After a short while his belly begins to swell. I think he has decompression sickness from coming up from 80 ft. The little guy is upside down on the surface of the bucket but can’t right himself or swim down. He is still flapping his gills and appears to be in some distress. Everyone on the boat feels bad for him. I, in particular, have guilt. This beautiful fish, which was honestly the highlight of our dive, is dying a painful death all because he was offspring of some rogue fish that was originally stolen from his home waters of
I give him over to the
This event still troubles me. Margo questioned me as to why I captured the little lion fish. I explained the reasons and she understood; but she had every right to feel that I was wrong in doing so. I don’t know if we have the power to stop this invasion. Since their first sighting last winter, there have been more and more captured each month. At best, we might be able to slow a complete invasion but I think the beautiful little lion fish is here to stay. Perhaps we should just enjoy them and see what nature will come up with in the new balance of life that is the
