Are you the scourge of the Caribbean?

Are you the scourge of the Caribbean?
Pretty but lethal?

Over the last decade or so we have been making our way around the Caribbean. My first encounter with a Lion fish was about 10 years ago when I heard that this invasive species from the Indo-Pacific region was slowing making its way around the Caribbean. I cannot say that I have been to every island in the region, but I have come close. I have seen them as far south as Tobaggo. I’ve seen them as far north as Florida. I have seen them as far east as Barbados. I have seen them as far west as Roatan, Cozumel and Playa del Carmen. Lion fish are eating and reproducing machines. A marine biologist in Belize told me that the female lion fish produces about 40,000 eggs every 3 days. The reproductive ability of rabbits pale by comparison.

One of my friends in Barbados let me know that last week his shop shot 90 lion fish while my friends in Roatan shot over 130 last week. There are lion fish round ups throughout the Caribbean. I have seen roundups in the Caymans, and Curacao and Belize. Ultimately, the lion fish has no natural predators in the Caribbean. Although there have been efforts to train moray eels, groupers and sharks to feed on them, often it still requires the spearing of the fish in the first instance. I don’t know what the answer is, but I certainly hope we find a better answer than we have now because from what I have seen we appear to be losing the battle.

Some might say so what. The problem is that with depleted native species, like parrot fish and others who eat the algae off the reef the reefs could eventually die out. I think about the great limpet that only resides in Monterrey bay and wonder, can we really afford such a loss. There are proteins that are created by the great limpet that make cancer drugs more effective and which at the present have not yet been synthesized. The proteins from the limpid sell for about $34,000 per gram or more than 600 times the price of gold. I wonder can we afford to lose even one species of flora or fauna in the Caribbean? I keep wondering if there is a better solution to removing this invasive species. Yet at the same time i think about instances in which people have introduced one invasive species to remove another and those efforts have gone terribly wrong,consider africanized bees….

The Sea of Abaco

Preserving the creatures of the Sea
Preserving the creatures of the Sea

In the Bahamas is the sea of Abaco. It is surrounded by Little Abaco in part, Great Abaco and several small Cayes. The sea of Abaco is very protected from storms and even when a substantial storm arrived on the last day of our sailing trip, it did not make the water very rough for sailing. Marsh harbor is the largest town in the area and has an airport and a nice harbor. The sea of Abaco is roughly 30 feet deep at its deepest and it appears that most of the diving is done in the “cuts” where water flows in and out of the sea. In the “cuts” the fish life is impressive. One of the fish that we found quite frequently were Nassau groupers.

Although groupers may make great tasting dinners, their stocks are under significant pressure from over fishing. Hopefully, groupers will not go the way of the dinasauers. They are the puppies of the sea, and can be remarkably friendly. Gary, as I referred to this fellow liked my camera and spent several minutes posing.

Shark with Sun Burst

The simplicity of design and the efficiency of sharks underwater makes it evident why sharks have survived on earth for millions of years. The impact of people on sharks is undeniable and sad. If we lose these majestic animals we will lose alot. Apex predators serve a very important purpose in nature. I hope we do not push them to extinction. Here is a short clip demonstrating their ability to move efficiently through the water.

What kind of diver are you?

The sharks that are feed in Nassau Bahamas are grey reef sharks. Even though they are not overly aggressive, they do lose teeth trying to grab and chew on the bits of chum. In a way this image does reflect the level of interest that you may find on many dives. Some divers will absorb all of the available information about the dive, while others appear to be rather bored or disinterested.

Some dives are just magical

On our first shark dive in Nassau Bahamas we were heading to the bottom. The grey reef sharks were starking to come into the dive site, but were very hesitant to mingle with a relatively large group of divers, 23 or so divers were in our group. So while the sharks were trying to determine if they wanted to check out our group I came across a hawksbill turtle at about 40 feet. He was heading to the surface so I followed him up for a while before I could get him between me and the sun. I thought about turning off the stobes so he would be only visible as a silhouette. But, decided his shell would add interest to the image.
