PCC Students Gain Hands-On Marine Science Experience at PICRC

The Palau International Coral Reef Center (PICRC) recently bid farewell to Palau Community College (PCC) students Aleeya Uraziri and Daissy Demei, who completed a one-month internship at the Center as part of their Environmental Marine Science program. The internship fulfilled the final course requirement for their degree—SC270 Field Studies, a four-credit course designed to equip students with ecological surveying techniques, hands-on experience using field equipment, and methods for collecting and analyzing data and specimens.

During their time at PICRC, Aleeya and Daissy engaged in a wide range of research activities. This included fieldwork such as deploying Baited Remote Underwater Video Systems (BRUVS) at a Fish Aggregating Device (FAD), conducting biological sampling of reef fish, such as collecting gonads and otoliths, data entry, and classifying gonad slides. They also joined a fishing expedition to collect fish samples, assisted with an intersession activity for 8th graders involving fish dissection, and learned how to write scientific reports and present their research.

Aleeya focused on fish sampling, analyzing existing PICRC data sets related to reef fish size, reproductive maturity, and their gonadosomatic index (GSI). GSI is a scientific metric used to assess a fish’s reproductive condition by comparing the weight of its gonads to its total body weight. This can be used to determine peak spawning times across the year or lunar phase, which can help managers determine when to protect species during their spawning periods. Her analysis focused on three commercially important species: Bluespine Unicornfish (Chum), Humpback Red Snapper (Keremlal), and Coral Grouper (Red Tiau), using her findings to explore whether these species are being sustainably harvested based on their presence in local markets.

Daissy’s research examined the presence of pelagic fish around a FAD using BRUVS footage. She analyzed whether lunar phases influenced fish presence and behavior at these devices, drawing connections to how FADs could help reduce fishing pressure on reef fish populations.

The data analyzed by both interns contributes directly to ongoing PICRC research and will support future reports and publications. Their work underscores the value of internship programs that provide students with real-world, locally relevant scientific experience.

“I particularly enjoyed the fieldwork, especially the trips to the FAD and deploying BRUVs,” said Daissy Demei. “One of the highlights was joining the researchers on a trip to Kayangel for a fish stock assessment, where we even spotted dolphins. I gained valuable knowledge, like how to dissect fish to determine their gender by examining their gonads.”

Aleeya Uraziri reflected, “What I enjoyed the most was dissecting fish and learning how to identify if they were ready to reproduce. I also got to work with the FAD team and help capture underwater footage of pelagic fish and sharks. Meeting new people and learning about the different kinds of research at PICRC made the whole experience really enriching.”

As part of the course requirement, both students concluded their internship by officially presenting their findings to PICRC staff and PCC faculty.

PICRC Chief Executive Officer Roxanne Siual Blessam emphasized the value of internship programs in building local capacity:

“PICRC is committed to engage with opportunities like these because they allow emerging marine scientists to learn directly from experienced professionals. Programs like this are essential in inspiring the next generation to carry forward the vital work of marine science in Palau.”

PICRC extends its sincere thanks to Aleeya and Daissy for their dedication and hard work. We wish them continued success as they pursue their careers in marine science.
