The Fish of the Austral Islands

After starting the barcoding of the total fish fauna at Moorea (Society Islands, French Polynesia) in 2006 under the BIOCODE project (http://mooreabiocode.org/), CRIOBE has spent the last 7 years continuing the genetic barcoding of coral reef fishes over the 118 islands, 5 archipelagos and 5.5 million km2 of French Polynesia. Of course the project could not visit every single island, but the project hoped to visit all 5 archipelagos for the fish surveys and sampling. Moorea has been sampled, the Gambier was surveyed in 2010, the Marquesas in 2008 and 2011, and now finally the Australs during this trip with the Global Reef Expedition. The Living Oceans Foundation has made it possible to conduct fish surveys at Raivavae, Tubuai, Rurutu, Rimatara and Maria Islands.

We discovered this distinctive new species of yellow-barred Dwarfgoby on our fish surveys in the Austral Islands, which is fully grown at about 25 mm in length. It lives on coral reefs at depths of about 25-30 meters.

Austral Islands Fish Surveys

The fish surveys resulted in the surveying of more than 300 fish species and we collected specimens representing about 14 new species that will be described over the coming years. In addition to these new species, this was also the opportunity to record new occurrences for many fish species previously unreported from the Austral Islands (about 20 new records). The results of this sampling program will be analyzed genetically and our findings will be made available internationally on the FISHBOL database.

The colorful reddish pink wrasse is similar to the Eightstripe Wrasse, but we have discovered that this color form is actually an undescribed species in French Polynesia

With these fish surveys completed, we have now collected over 5000 vouchered fish samples for French Polynesia.  These samples will provide one of the most extensive databases of fishes worldwide for a region as large as French Polynesia.

After the Storm: Standing with Our J.A.M.I.N. Family in Jamaica

There are moments in this work that feel heartbreakingly familiar.

Two weeks after we completed our Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) programming, Hurricane Melissa made landfall. A powerful Category 5 hurricane, Melissa is now tied with Hurricane Allen in 1980 for the strongest winds ever recorded in an Atlantic storm. Like Hurricane Dorian, which devastated The Bahamas in 2019, Melissa will be remembered as one of the strongest hurricanes on record in the region.

For 11 years, the University of the West Indies Discovery Bay Marine Laboratory and William Knibb Memorial High School have been more than program partners. They have welcomed us into their classrooms and labs, shared meals and laughter, and committed themselves to educating their students about mangroves and coastal resilience. These colleagues and students are not distant collaborators. They are family.

And they were hit hard…

B.A.M. Turns 10: A Year of Milestones, Resilience, and Growth

The 2025–2026 academic year was one of those defining years for our Bahamas Awareness of Mangroves (B.A.M.) and Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) programs. It was a year marked by celebration, challenge, growth, and powerful full-circle moments, and a reminder of why mangrove education matters.

In The Bahamas, B.A.M. reached a major milestone: ten years of partnership and environmental education in Abaco. Since 2015, in collaboration with Friends of the Environment, we have worked alongside Patrick J. Bethel High School and Forest Heights Academy to bring hands-on mangrove science into classrooms and into the field. This year, we were proud to expand the program to S.C. Bootle High School, increasing access for students who live…
