This fish is an attack predator with a number of hunting techniques: lying to wait in coral, swimming in mid water, following other predators like eels and octopus and catching their prey if originally missed, and hiding within schools of fish and darting out at unsuspecting prey. Habitat: C. Argus can be found on shallow exposed reefs in warm tropical waters.

It is a protogynous hermaphrodite, meaning it begins life as a female and changes to a male as it matures. It is treatable in humans, but the concern is that ciguatoxin can move up the food chain via bio amplification and spread to other species.

The peacock grouper became established and populations expanded on Hawaiian reefs, but local consumers lost interest after a number of cases of human neurological disease were traced to ciguatera poisoning linked to the species. The researchers took samples from nearly 300 fish, hoping to find patterns in geographical location, size or condition that would allow them to predict which populations or individuals were safe for human consumption.

But we have an imported grouper species all throughout the main Hawaiian islands called the ROI or peacockGrouper. This fish was imported to Hawaii in the 1950s from French Polynesia and since then has spread to almost all the Hawaiian coral reefs.

Where it occurs naturally in Tahiti it sells for up to $8 a pound and is a prize dish in the local restaurants. Even though this 20-inch long fish is now very common in Hawaiian waters and easy to catch it is not often eaten by the local community.

Then the ROI just gulps it down with its large mouth and series of hundreds of small bristle like teeth. If it contains ciguatera you would have some kind of mild stomach reaction within three to five hours according to the finding from the UH study.

Catching the ROI for food is a good sustainable food source that helps our coral reefs and maybe we can lower the populations to help our native fish species, but each person who chooses to eat them really needs to be cautious and not eat a large portion of the fish right way until you know it is safe. The ROI are extremely beautiful fish to look at, and they may or may not have white bands on their blue and brown smooth skin.

Toucan see the ROI in action in my video The Worlds Guide to Hawaiian Reef Fish up on my underwater educational web page at www.underwater2web.com and also follow my marine life identification series on my Instagram at terry.Villa. ROI or peacock grouper, were introduced into Hawaii in 1956 from Mo'area to add to the food source for Hawaiian fishermen.

ROI spend most of their time in deep caves and cracks in the reef where they prey on other fish like allowed, Memphis and Ala'hi. I also make movies for schools, government agencies and the public about our marine life and invasive species like ROI, ta'ape and to'Au.

I have observed several large ROI that seem to stay near the same caves, but they will move when the surf changes or you scare them away. In Canada Bay from the shore out to one mile I have done over 100 kayak scuba dives and I have speared over 80 ROI of which I sent to UH for testing.

This concentration of ROI vs native fish is very dangerous for the long term health of our reefs. Ten years ago at many spots on the north shore like Tunnels Reef, I have seen many of the native fish decline and the ROI spread.

Fishermen do not normally eat the ROI because they have been known to carry the ciguatera toxin, and they could make you very sick! The current test kit for ciguatera is not extremely accurate and cost a lot.

If UH could make a good test kit that cost little then fishermen could go back to catching and eating ROI. Free divers can target certain species without damaging the reef or marine life.

Some scientist claim that ROI take the place of Ulna as a top predator. If we spent more time and money studying Ulna, UK, Mile and other predators and develop additional plans to increase their populations, then we would be returning our reefs to a healthy state.

Using an invasive species to repair a damaged ecosystem rarely if every work! Roi could also carry bacteria that are not native to Hawaiian waters. I did an underwater movie about Kauai's free divers, and they are very good at what they do, and they understand the ocean and marine life quite well.

Rising sea levels, run off, improper building, polluted rivers and over use of certain reefs by tourist cause much more damage to our coastal ecosystem than fishermen do. As scientist, we need to work with fishermen, divers, surfers, hunters and other native people as they are “the eyes on the reef” we need to learn from and share with.

The burning, itchy rash did not appear till the next morning…by that time the upset stomach part was subsiding, but these other problems…what was going on? As to the other bizarre symptoms, he said that he had no idea and that I should concentrate on stopping the diarrhea.

The reason that my doc had no idea is that this is a fairly unknown disease in the U.S. except for South Florida, BUT, it’s getting more prevalent in our country as more fish species are being imported and waters around the world are becoming warmer. Other culprits besides black, yellow fin and dusty grouper are: barracuda, amber jack, king mackerel, cuber snapper, dog snapper and hog fish.

If you would like to read more information about ciguatera written in a more scientific way, toucan read this from the Centers for Disease Control and Prevention and also this warning from the World Health Organization. Here is a very comprehensive essay by Professor J. Learn, Graduate School of Medicine, University of Queensland, Australia on the neurology of ciguatera.
