In Defense of the Lionfish

The lionfish is a Pacific fish that began populating the Atlantic ocean and the Caribbean sea about two decades ago or so. According the NOAA (the U.S. National Oceanic and Atmospheric Administration), the exact date and the manner by which the fish arrived on this side of the Americas is unclear, but what is sufficiently clear is that it was humans who facilitated its arrival. The lionfish is a predator that feeds on small fish. The main issue with the lionfish is that, because of its recent introduction into the Atlantic's and Caribbean's ecosystems in evolutionary terms, the lionfish has no natural predators. Fish that would normally feed on lionfish in the Indo-Pacific, such as groupers and moray eels, do not recognize it as pray in the Atlantic.

As hard as they tried, humans have not been able to teach those Atlantic cousins of the Pacific lionisfish predators, to eat lionfish. Every attempt of such biological control has thus far failed. For example, in Bonaire, a few years ago, people started feeding dead lionfish to moray eels. The eels ate the lionfish, being naturally immune to its venomous spines, but after a while they started becoming aggressive towards divers as they began to associate the latter with food. Also, the eels were not seen hunting live lionfish because they probably did not associate the dead lionfish with the live ones.

I remember that shortly after lionfish was first sighted in Bonaire, STINAPA (the Bonaire National Parks Foundation, Stichting Nationale Parken Bonaire) started giving divers corks attached to plastic strings so that recreational divers could mark where they sighted the fish – thus contravening the marine park rule that forbids divers from tying anything to the reef. Park rangers would then collect the marked lionfish. This type of mechanical control is possible because the lionfish is a territorial animal, meaning that it tends to stay in one particular spot. The downside of this strategy was that within a few months the reef started to look like a surreal giant holiday decoration. On every dive one could see several corks floating around the reefs. Even worse, sometimes the corks would detach from the reef and float to the surface, thus posing a hazard to turtles who could choke on the plastic string believing it was jelly fish. Needless to say, this plan was also scrapped.

Thus far, I summarized the history of attempted mechanical and biological controls of lionfish in Bonaire. The reason why I am mostly concentrating to attempts in Bonaire is because I have first hand experience of it during the many years I have been visiting the island. Yet, it is likely that similar overzealous attempts to control the spread of lionfish are being tried elsewhere in the Caribbean and on the Atlantic coast of the United States. In fact, I recently saw a video on YouTube of a Divemaster feeding a dead lionfish to a toadfish in Roatan (below). I have also personally witness this on the Mexican island of Cozumel.


Today, PADI – the Professional Association of Diving Instructors and by far the largest association of its kind with more that 50% of SCUBA dive certifications – promotes the Invasive Lionfish Tracker distinctive specialty course, where the student is taught to "safely and humanely capture and euthanize these fish." (Notice the clearly speciesist language wrapped in seemingly neutral terminology. I wonder if any human being would be amenable to be deprived of life through no fault of their own if it were done safely and humanely. I would think not, but that's the crux of speciesism: the idea that humans are somehow superior to other species by virtue of their might.)

According to the Cayman Compass, in 2013 PADI had some misgivings about promoting the indiscriminate killing of beautiful sea creatures such as the lionfish. But then, still according the the Compass, it reversed itself once more (perhaps bowing to the pressures of Caribbean dive operators who believe that lionfish are bad for business: i.e. no fish, no divers). In the story, Norma Connely quotes Brad Smith, training manager of PADI Americas, saying that "in light of the destructive nature of the invasive lionfish [we] determined that it was worth making an exception" to their no-take approach to marine conservation. This would help explain PADI's sanitized course description I quoted in the previous paragraph. In addition, still according to the Compass, PADI has also approved the more 'inhumane' spearfishing of lionfish by individual Caribbean operators. One such operator is Ambassador Divers in Grand Cayman:



In Bonaire, STINAPA promotes its own 'inhumane' version of yet another PADI approved Lionfish Hunting distinctive specialty course. On Bonaire's VIP Diving's website, for example, one can see a student practicing his spearing skills with al E.L.F. removal tool (Eliminating Lion Fish tool, basically a trident shaped spear with a fairytale-sounding name) with a smirking partner (instructor, perhaps?) at his side (below). For $150 one gains the privilege of having a license to kill fish on otherwise protected reefs.


In the picture's foreground, we see the Zookeeper™. The device allows the certified reef killers to store the moribund lionfish for the remainder of the dive. The slogan of the manufacturer being: "until a natural predator emerges."


Given all this, it seems that the lionhish,  at least in the North American and Caribbean diving cultural cohorts, has replaced the shark as the evil creature that must be destroyed. And as divers continue to campaign in defense of sharks in order to change its unwarranted media fueled image in the popular imagination, they seem to have directed their own thirst for blood onto the lionfish.

So, why is all this problematic?

As you may have guessed by now, this post is about humans first destroying their environment and then creating even more havoc as they try to rectify the situation. Perhaps this story could be taken as a cautionary tale on the idea that climate engineering may the best and easiest way to ameliorate global warming and its nefarious effects on the environment which includes coral reefs. But this is also, as we shall see, a story of the tendency of humans to scapegoat others for their own failures.

At face value, it seems self-evident that the eradication of an 'invasive' species that appears to threaten the balance of an entire ecosystem should be deemed a top priority. (I put 'invasive' in quotes because this term is problematic in itself.) But this appearance turns out to be just that. Not because the lionfish is not a disrupting element in the Atlantic and Caribbean ecosystems, but simply because, as the NOAA and others assert, the remedies that have been implemented are ineffectual. According to researchers De Vries, Rannap, and Briggs, for example,
a well-established exotic species can be almost impossible to remove from a community. Threats posed by invasive species today are so severe that reducing the rate of their introduction needs to become a greater priority in conservation efforts.
"Most scientists agree," the NOAA writes, that "it is unlikely that the lionfish's invasion of U.S. waters can be reversed." In addition, "scientists predict that lionfish will continue to increase in abundance." However, "scientists do believe ... that lionfish can be controlled in some locations, such as some Caribbean islands and marine protected areas." In regard to this latter point, my own admittetly unscientific personal experience in Bonaire shows that lionfish is still proliferating regardless of containment efforts.

If eradication efforts of lionfish do not serve their stated purpose, what other purpose can they serve? And if these efforts are about lionfish population control, what are the costs of these efforts to the ecosystem? In my opinion, while attempt to control lionhish population is definitely a factor, the manner in which these efforts have developed and the way they have been popularized is also sign of some deep seated human psychological drives.

As mentioned earlier, one such drive is the apparent need to scapegoat and punish someone, or something, for one's own failures. In regard to lionfish, this drive assuages and redirects the anger of those who are unwilling to seriously look at what is really endangering the world's reefs – namely, global warming.

This type of tunnel vision reminds me of a scene from Jacques Cousteau's famous movie The Silent World (1956). In the scene, the RV Calypso (Cousteau's research vessel) encounters a group of sperm whales. As they follow the whales, a baby whale who cannot keep up with the group falls behind, and as it gets too close to the boat it is mortally wounded by the propeller. Here, Cousteau the narrator is quick to blame the whale's "childish carelessness" as if it should have known what a propeller is. During the next several minutes we watch the small whale in agony as it frantically swims trying to catch up with the group. As she continues hemorrhaging, one of the sailors puts her out of her misery by shooting her. At this point several sharks, attracted by the whale's blood, start attacking the whale's carcass. Cousteau continues his narration saying that "every seaman hates the sharks" and that after witnessing such an attack on the dead whale "the divers can't be held back. They grab gaffs, books, anything they can to avenge the whale" (emphasis added).

And so the carnage begins, the Calypso divers start killing one shark after another. They pull them onboard with hooks while one of the divers hits them with an axe. All this to "avenge the whale." But wait, wasn't it the Calypso that killed the whale? Shouldn't revenge thus be taken on whomever failed stop the engines before the Calypso hit her? The sharks simply did what's in their nature. Yet, the rage of the sailors was visited upon them. And so the divers not only ended up with a dead whale, but also with a bunch of dead sharks. Some vengeance. The depressing part of all this is that in the mind of the divers, as well as that of Cousteau, the killing of the sharks was entirely justified. (The scene begins at 52:04 and ends at 1:01:40).


Sixty years later, the similarities between the Calypso shark carnage and the hunting of lionfish are striking. Today we have so-called stewards of the oceans, namely divers – supposedly with much higher consciousness than Cousteau and his cohorts had – who are intent on killing and maiming a fish whose presence in this part of the world is solely due to human behavior. Yet, against all scientific evidence on the feasibility of eradication and, perhaps, even control, the carnage of lionfish not only continues unabated but it has become some sort of sport to be celebrated over drinks.

For example, on Saturday, June 21, 2014 STINAPA opened the Karpata Reserve (normally closed to divers) to lionfish hunters in support of the Bonaire Culinary Team. Prizes were "distributed to the biggest, smaller and most lionfish." In the hunting call, Ramón de León, the park's manager, wrote:
If you think you are the one that catch [sic] the most, you better start counting before we start drinking. 
... 
Let's get some fish for Bonaire Culinary Team show to [sic] irresponsible FL citizen releasing exotic species in the wild what we do with the pest they start.  
WHO IS GAME?????
This is what in psychology is commonly described a cognitive dissonance or the ability to entertain two contradictory concepts in one's mind. The concepts of the shark and the lionfish are contradictory because, on the one hand, divers have no qualms in pontificating about how other cultures – namely the Chinese and Japanese – are decimating the shark, whale, and dolphin populations; at the same time they are also eager to engage in the same type of behavior when it comes to lionfish. And while lionfish is not endangered like sharks or whales the mindset is the same.

To understand the irrational nature of the whole enterprise one simply needs to be on a dive where a lionfish hunter is present. The hunter becomes the star of the dive, a revered figure intent on performing a kind of sacred rite. Many divers willingly volunteer to spot lionfish. The excitement that ensues when a diver spots one is palpable. As the hunter approaches its oblivious victim and goes for the kill the excitement turns into a frenzy. In some ways it's a spectacle that is reminiscent of ancient Roman circuses, medieval lynchings, and more recent bullfighting. One cannot help wondering if we are actually much different than those who we look down to with patronizing disdain.

The lionfish hunters not only terrorize the lionfish, but as they try to spear their victim they inevitable hit corals, thus damaging the surrounding ecosystem and scare off any fish in the vicinity. Whenever the hunter misses, which happens quite often, the lionfish escapes by creating a cloud of silt that ends up covering the nearby corals. In addition, lionfish hunters tend to mostly hunt on islands' leeward side and at shallow recreational depths – which means that lionfish that exist in remote areas and at depths greater that forty meters are free to reproduce and proliferate.

Thus, the question ensues: are these clear damages to the reefs worth the effort, or is it just a way to attract and excite tourists like the now ubiquitous shark feeding dives? One could argue that lionfish hunting is even more exiting than shark dives. In the former we get to see someone actually die. Perhaps somebody should start a reality TV show called Lionfish Hunters.

Ineffectual and damaging efforts notwithstanding, divers all over the Caribbean and beyond have convinced themselves that it is possible to eliminate or at least contain the spread of lionfish. A lot of resources are directed in this direction while not much has been done in regard to the real threat that marine ecosystems are faced with. For example, in 2001, a study by the NOAA concluded that "the majority of the world’s coral reefs are threatened by human activities." According to the report, coral reefs could die by 2050 – with or without lionfish  – due to acidification and warming temperatures. On Australia's Great Barrier Reef scientists have just recorded the biggest ever coral die-off.

In other words, the marine ecosystem is, in latest instance, not threatened by lionfish, or by sharks, but by humans like you and me. And yet, the discourse of lionfish as an 'invader' has become somewhat of an obsession with divers – perhaps fueled by equally bogus discourses on illegal immigration. Could this be a case of false consciousness? Could it be that as we – with the U.S. in the lead – are intent on destroying the world as it is, we are trying to distract ourselves from the one thing that must be done with futile concerns such as lionfish hunting and coral restoration projects?

While it is understandable that individual divers feel powerless against the systemic threats of expansionary capitalism to the ecosystem, it is not clear how the killing of a few million lionfish is going to prevent us from destroying ocean reefs with our own polluting activities. It seems that, like Cousteau before us, we haven't learned to first look in the mirror, take responsibility for our own actions, and try to change our own systemic behavior before scapegoating some other creature or people. In this regard, the clear impossibility of eradicating the lionfish should perhaps be seen as a sobering reflection of our own systemic failure as a supposedly intelligent species.

Save the Puffers

The puffer fish, in all its varieties, is one of my favorites. The porcupinefish is one such variety and it is very common in the Caribbean. No matter how many times I come across one, I can't help pausing and look for as long as it will let me before swimming out of sight. Turtles and eagle rays also have the same effect on me. Maybe it's because of the puffer's wide eyes which we, as humans, are genetically programmed to associate with infants in order to trigger our nurturing instinct. Or maybe it's because they seem so gentle and cute with their ET-like face.

One of the peculiarities of the puffer fish is its natural defense mechanism. Its body, is covered with spines, and whenever it feels threatened, the fish will suck in sea water and fill itself up until it turns into a balloon. As it does this, its spines become erect because of the body's surface tension and so, once puffed up, the fish will resemble one of those medieval spiked iron balls which would look pretty menacing to anyone who has ever seen one. Granted that the puffer fish is not made of iron and thus it wouldn't hurt anyone (with the exception of those puffers that have venomous spines), but its predators don't know that, and fish in general are not known for their intellectual acumen.

We humans, who possess such intellectual acumen, have figured out that the puffer is not really as menacing as it looks when puffed up. This is unfortunate from the puffer's perspective because some uneducated divers, and some uneducated snorkelers and aquarium owners alike, will simply try to trigger such a defense mechanism for their own amusement. Aside from the cruelty of a behavior that is tantamount to torture - just imagine a Kong like creature scaring you to death for its own amusement - the puffer's defense mechanism is not without drawbacks.

The main drawback is the fact that the puffer fish can only puff itself up so many times before it exhausts itself and dies. That's right, just think of a bee's stinger. The bee's stinger is a defense of last resort and the bee will sting if, and only if, it feels it has no other option. This is because the bee is aware, somehow, that when it does utilize its ultimate weapon, it will die as well. Sort of like: "I know I will die, but I will hurt you as much as I possibly can before I do."


Even though the puffer's defense mechanism does not have the same one-time-only finality of the bee's stinger, it still is the weapon of last resort in the puffer's arsenal, and because of the risks involved, this mechanism is reserved only for staving off an imminent threat. Like all animals when they sense danger, the puffer fish will first try to swim away first and will only resort to puffing up if and when it feels it has no other way out.

All in all, the puffer's puff is like the emergency brake on a subway car, or on a train, with its big red handle and its big red sign saying "Emergency!" Nobody in their right mind would pull that handle unless it was a real emergency - even though I am sure everyone has had the temptation of pulling it just to see what would happen. But aside from the few obsessive compulsive people or the remainder reckless ones, most people will not pull on the lever because of the predictable negative consequences - some people will get hurt, and the perpetrator will receive a substantial fine.

So the question is: why is that people who are smart enough not to pull on the emergency brake in a subway car just for kicks, will carelessly trigger the puffer's defense mechanism given that this could cause the fish's death? I have already hinted on the most likely answer to this question earlier in the blog, which is that I believe that people are simply unaware of the potentially deadly consequences of forcing a puffer fish to puff up too many times. So, it's not so much that people are mean but, simply, that they are ignorant; and this goes to show that ignorance, sometimes, makes people do some pretty mean things. I am sure that if anyone knew the unintended consequences of molesting a puffer fish, people would not do it.

For this reason, and per suggestion of my always inventive friend Laura, I have decided to start raising people's awareness on this issue. This blog, in its own little way, is the first step in what will hopefully evolve into a Don't Scare the Puffers campaign (the name is still a work in progress; feel free to make suggestions). Hopefully, with a little more awareness, people will refrain from molesting such a beautiful creature and will do what every properly trained diver is supposed to do: look but don't touch.

Squids

They are some of the most fascinating and mesmerizing creatures. I particularly love the way they change color as they change their luminosity, and how they float effortlessly by gently waving their undulating fins.

Last October I was lucky to encounter a pair of extremely friendly squids in Bonaire, and this allowed me to shoot some very good close-ups. The fifth picture in this series is my favorite.

Horse-Eye Jacks

Every time I look through my Bonaire pictures, I keep pausing on this one for some reason. Maybe it's the red reflexes in those big eyes, or maybe it's the fact they are going for something but we can't see what it is.

New Diving Friends

A couple of videos I made with footage taken while diving with people I met in Bonaire this past October.

Mexico

There was a little bit of a pause with this blog due to a quick gateway to one of my favorite diving spots: Cozumel, Mexico. With the H1N1 flu scare in full swing, I was able to find an airfare that I couldn't refuse. Also, since there are currently more cases of H1N1 flu here in the NYC area than in Cozumel, why not go and support the local economy?

It seems like many people had a similar idea as both flights to and from Cozumel from Houston were completely full (unlike the Newark flights to and from Houston). The hotel was also practically full, and the weather was great for the duration of the trip. On the other hand, I did carry a box of very expensive Tamiflu ($100 for 10 pills) as a precaution.

Consistently with reports I had been reading prior to this trip, the lionfish is now established in Cozumel. I personally saw two specimens: one at Punta Tunich, and one (pictured below) right in front of my hotel during a night dive.


The lionfish is a very pretty fish if it wasn't such a biological nightmare. Some dive guides would capture the fish when they found one, but given the numbers, it seems like a pretty futile exercise.

It is also hard to believe that the lionfish is part the same family of this scorpionfish, found just a few feet away from it.


Lionfish aside, I saw some pretty great stuff as it's usually the case in Cozumel. The Splendid toadfish, for example, is very funny looking fish, and it's endemic of Cozumel. Unfortunately this picture is a little blurry.


The octopus is always an intriguing animal, especially when one catches it shooting ink!


I have to say that this was a pretty lucky shot as a diver on my left scared the octopus right as I was taking the picture.


Most of these pictures were taken during a single night shore dive in front of my hotel.

Here is another favorite: the porcupinefish, a cute, ET looking fish. This one in particular was very friendly kept getting closer and closer to me as I was trying to shoot a movie.


This trunkfish was also very pretty.


A spotted moray that looks like part of this cement block.


A pretty banded coral shrimp.


And finally, the always awe inspiring nurse shark.


Now that I'm back in New Jersey, I can't wait to get my new dry suit. This way I will be able to do some local diving without getting too cold, until the next tropical trip: Bonaire in October.

Military Coup in Honduras

As a diver, I wonder what will be of the Bay Islands with this military coup in Honduras. Some American expats there, are already sounding like the character Hyman Roth in the movie The Godfather:

"[I]t looks like they got rid of a Chaves [sic] wannabe....and if so good for them".

"The military intervened to impose the rule of law just clarified by their supreme court and congress. Hats off to them..."

With such comments, no wonder people like Hugo Chavez in Venezuela have an easy time fomenting anti-American sentiment in the region.

While I do understand that divers are generally wealthy people, I would also like to believe that they are people with some kind of sensibility toward the environment, the rule of law, and the planet's overall well being. But I guess this is an overly romantic view of the diving community.

The reality, as it seems to transpire from comments such as those above, is that by selfishly aligning themselves with the local wealthy ruling elites, Americans expats keep reinforcing the notion that when it comes to Central America, the United States care more about hegemony than the rule of law.


(source)

I was in Roatan in 2007, and I have seen some of the abject poverty that the locals live in. While there is something to be said about tourism bringing cash to the Bay Islands, it is also true that most of the money does not trickle down to the local Hondurans. Most dive resorts are foreign (i.e. American) owned, and they operate on a "all inclusive" model in order to shield tourists from the surrounding reality as much as possible.

Timothy Padgett has some interesting comments in regard to the current military coup on Time Magazine's website:

"[W]hen soldiers in Latin America haul a democratically elected president out of his palace and into exile, the U.S. has no choice in this day and age but to roundly condemn it. Not just to throw Washington's hemispheric antagonists off base — but to keep the region's military troglodytes from making a comeback."

For a while, I had been planning a return trip to Roatan, plus Utila and a side trip to the mainland to see the Mayan ruins in Copan, for 2010. But as things stand right now, it doesn't look like this trip will be happening until there is some return to normalcy in Honduras.

Dry Suit Diving

Last Sunday I tried diving with a dry suit for the first time. I have to say that before trying I thought that I was not going to like it, as I always enjoyed the part of being wet in the water. Also, it seemed like a big effort to put on a dry suit. After trying one on, and doing two dives, I have changed my mind and now I am thinking on buying one.

I find dry suit diving neither better, nor worse, just different. It adds a little more separation between the person and the water;not like being totally separated as in a submarine, but more so than a wetsuit where one feels totally immersed in the water. I guess it's hard to explain
and that's why I wasn't sure what to expect. But it is definitely something worth considering simply because it expands the diving horizon.

I initially got interested in dry suit cold water diving after seeing Werner Herzog's Encounters At the End of the World: a great documentary and with some astounding under water images. Definitely worth checking out even if not a diver.
