The State of Hawaii has banned, at least temporarily, the collection of fishes for the aquarium trade. Activist groups pushing for this ban to become permanent are using various “scientific facts” — saying, among other things, that the aquarium fishers are guilty of:

• “Devastating” the reefs of Hawaii
•  Engaged in a trade in which “99% of the collected fishes die within a year”
• Taking up to “half a million fish per month” out of Hawaiian waters

(Link: Latest news on the Aquarium Fishery Ban)

These are, in fact, demonstrably “Fake Facts” or based on what most biologists say is pseudoscience and fabricated numbers. A recently exposed chain of letters reveals how respected marine biologists are thinking about this historic situation.

CORAL Magazine has received copies of the relevant correspondence and is publishing it here in a chronological fashion for all interested aquarists and other observers to read first-hand. We have highlighted, in boldface type, several key portions Dr. Carlson’s letter.

An Example of “Fake Facts”

The Turtle Island Restoration Network (TIRN) is one of a number of organizations working toward a permanent ban on aquarium fishing. A recent statement from TIRN, authored by Cheryl King, Hawaii Program Director for TIRN, came out in strong support of killing the “devastating” aquarium fishery in Hawaii. With a science advisory board that was 10 members strong including 7 Ph.D.s in mid-2017, these statements on behalf of the organization are certainly positioned as credible, science-based arguments. This, however, is how TIRN is presenting its view of the “facts.”

Aloha Friend,

Cheryl King, Turtle Island Hawaii Program Director

Last year, with the help of thousands of Turtle Island Restoration Network supporters, we urged Hawaiian state legislators to support a bill that would have ended the unsustainable aquarium trade in reef fish.

The aquarium trade snatches wild fish from coral reefs, puts them in plastic bags, and ships them off to be sold for private aquariums. As you can imagine, a staggering 99% of these animals die within a year and require replacement.

Some activists have estimated that half a million fish are caught every month by this industry. Our coral reefs simply cannot handle this extraction – the fish need to stay on the reef where they belong!

The bill made it through both houses and ended up on Governor David Ige’s desk, where, much to our disappointment, he vetoed it.

Fortunately, a separate litigation track was underway by an allied organization.

Last week, in response to a favorable court ruling, the Hawaii Department of Land and Natural Resources announced that no aquatic life may be taken for commercial aquarium purposes off West Hawaii until an environmental review is completed.

Stopping the aquarium trade will help protect Hawaii’s magnificent marine fish, including yellow tangs, Potter’s angelfish, blueline butterflyfish, moorish idols, and so many more.

Let’s celebrate this victory!

But as with any victory, we must stay vigilant, especially as the environmental review is conducted.

Stay tuned for how you can help us watchdog the environmental review process to make sure that Hawaiian coral reefs are truly protected from this devastating industry.

TIRN Scientists Weren’t Consulted About the “Facts”

TIRN plainly states as fact that “a staggering 99% of these animals die within a year and require replacement” and that “activists have estimated that half a million fish are caught every month by this industry.” But is there any truth here?

In reality, it has become apparent that the TIRN position statements against Hawaii’s aquarium fishery were likely never run by the actual scientists on their science advisory board. One of these listed science advisors, Dr. Robert Hueter, is the Shark Program Director for Mote Marine Lab in Sarasota, Florida.

In a response to TIRN’s statement, Dr. Hueter calls TIRN’s allegations into question and reveals that in fact, he likely would not have supported the position taken by TIRN, had he ever been approached. In fact, his very role as a science advisor to TIRN is framed, quite clearly, as effectively non-existent, raising serious questions about the validity of TIRN’s science advisory board, and ultimately about the credibility of TIRN’s positions. In Dr. Hueter’s response, he references the recent writings of his colleague, Dr. Bruce Carlson.

To: Alex Hearn, Ph.D. 

Hi Alex et al.:

It’s come to my attention that I’m listed as a Science Advisor for the Turtle Island Restoration Network. I think this is something that Alex invited me to be a few years ago, but I don’t believe I’ve heard anything from the group since. I see my name and photo on your website ( with an out-of-date bio.

I see that TIRN is now taking credit for legislation to stop the Hawaiian aquarium trade (below). This is not something I would’ve necessarily supported and, given the chance, would have discussed the sustainability of this trade with you. Please see the attached editorial on this issue by my respected friend and aquarium expert, Dr. Bruce Carlson.

If TIRN is going to continue to operate like this, taking semi-scientific positions without consulting its own Science Advisors, then I wish for you to remove me from your list of advisors.

Please let me know how this will be handled as soon as possible.

Best regards,

Bob Hueter

Modus Operandi In An Era Of Fake Facts

Dr. Bruce Carlson, a highly respected marine biologist (former science director of the Georgia Aquarium, former director of the Waikiki Aquarium), has been actively responding to the misinformation campaign intent on destroying Hawaii’s aquarium fishery. In this instance, he responds to TIRN’s statement, and the response of Dr. Hueter, in an open letter currently circulating among the aquarium fishery and marine biology communities concerned about the future of the aquarium fishery in Hawaii.

You can now see how the misuse of science and scientists (you) has resulted in the present situation in Hawaii, where one of the best studied inshore (and most highly regulated) fisheries has been trashed by passionate and very misguided individuals. They are led here by a few master manipulators of disinformation spewing forth wild accusations based on anecdotal evidence.

Of the scientists (those with Ph.D.’s, anyway) who speak up against the aquarium fishery in Hawaii, none of them present data-based evidence of harm to the fish populations or the environment, but rather only offer speculation based on untested hypotheses and anecdotal evidence, e.g., removal of the yellow tang, a herbivore, leads to rampant algal growth and coral mortality. I would like to see a peer-reviewed paper supporting this conclusion that harm has come to the reef environment in Hawaii as a result of the Aquarium fishery.

Conversely, Brian Tissot and Leon Hallacher (2002 Cons. Biol. 17(6): 1759-1768) went out in the field and actually did the hard work to collect data and found no significant differences (algal cover, coral damage) in areas where fish are collected compared to protected areas nearby (DLNR has similar data). They DID report a “significant” difference in the populations of aquarium fishes in the two areas (no one disputes that there should be fewer fishes in areas where they are being collected). But to show you how scientific terms are corrupted by opponents, they equate “significant” with “damaging” (it’s reminiscent of the issue we have with the public misunderstanding the concept of “theory” used in a scientific context).

The reason so few scientists here support opponents of the aquarium fishery is because of the solid data collected by Dr. William Walsh and his team in Kona over the past 19 years. These data show incontrovertibly that this fishery is the textbook definition of “sustainable” (in fact, in recent years, right up to the present, yellow tang and kole populations have been increasing in both fished and non-fished reefs on the Kona coast). Dr. Bill’s data set is widely admired and respected by scientists as some of the best data ever collected anywhere in the world on an inshore reef fishery.

Bob, you aren’t the first scientist to unknowingly be name-dropped as an opponent to aquarium fishing in Hawaii. I recently spoke to another Hawaii scientist whose name appeared in testimony last year, and he was very surprised because he gave no such permission to use his name, nor did he agree with their position.

To be fair, there are some scientists here who are “preservationists” who simply believe that the fish should be left in the ocean – period. That, however, is a philosophical argument, not a science-based one; but at least it’s honest. We argue equally that the jobs created by this fishery and the value of aquariums are also very important. And we have data on our side, so we know we aren’t compromising our conservation principles.

The information presented by most opponents, including what I read in the TIRN report below, is dishonest, inflammatory rhetoric. Notice what they say: “Some activists have estimated that half a million fish are caught every month by this industry.”

Yup, they manufacture their own false data, then quote it back as fact. You and I are both conservation biologists and have taken strong stands for conservation over the years, but I’m sure you see, as I do, that some environmental groups use pseudoscience as their modus operandi, and we as scientists have to keep a great distance from such people. I’d lump these folks right in there with the climate change deniers: same methods, same exasperating anti-science rhetoric.

This is the age of fake data and anti-science, and this is just another very sad case, from a group whose mission otherwise seems laudatory. It’s entirely possible that they too (TIRN) have been duped by the Hawaii activists and probably have not read the many research papers on this topic. If these people would put just a fraction of their misdirected energy in correcting real problems with our marine environment, following the lead of real scientists, we might actually make progress. Biologists here are MUCH more concerned about our food fishes being overfished, but you don’t hear a peep about that from these anti-aquarium activists. I hope that will change now that more reports from NOAA and University of Hawaii researchers are presenting data about these very real concerns.

Unlike the leaders of the opposition, who are well-paid and funded by national organizations, and who fund-raise by inflaming public opinion (case-in-point: the attached TIRN document), I’m still trying to keep them at bay using my home computer on my own nickel because I hate to see good science being trashed, and because I know that aquariums can be valuable educational, inspirational, and research tools.

You did the right thing, Bob.
