Fishing is who we are. Can it stay that way?

By Leilani Sablan Naden, program lead for Guihan for Guåhan
Ask a fisher about fishing in Guam today, and you may hear a familiar sentiment: it just isn’t like it used to be. Trips that once brought home a cooler full of fish may now require more time and effort for a smaller catch. For many, these changes are not abstract scientific observations. They are lived experiences, passed through conversations at the boat ramp, around the dinner table, and among generations of fishers.

Sustainable Start

At the University of Guam Center for Island Sustainability & Sea Grant (UOG CIS & Sea Grant), we define sustainability as the balance between meeting current needs and safeguarding the resources of future generations. Established in 2009, UOG CIS & Sea Grant is the region’s lead institution for supporting the transition toward a sustainable, self-reliant, and prosperous island community.

Ocean of Reach

Since our founding, UOG CIS & Sea Grant has evolved into the region’s focal point for sustainability research and community outreach. We collaborate closely with government agencies, NGOs, and community groups to address critical island needs across four key pillars: Environment, Economy, Society, and Education.

A Green Future

With an expanding portfolio of implementation projects and strong community partnerships, UOG CIS & Sea Grant is moving the region toward a sustainable tomorrow. Our work is defined by action. Through transformative programs like Guam Green Growth, the SEAS Islands Alliance, and Navigating Home, we are turning sustainability plans into on-the-ground reality.

On Saturday, October 10, Guam will see something it has never seen before: individuals and families walking side by side from the island’s northernmost tip to its southern shores in support of autism awareness. The inaugural “Walk Different” event, co-organized by Cruz and Off The Spectrum, will take participants from Andersen Air Force Base to Merizo Pier and Cocos Island, beginning at 12:00 AM and ending at 4:00 PM.

Curious by nature: An intro to REEF intern Riyo

My name is Riyo Anne Reyes and I’m a Research, Education, and Extension Fellowship (REEF) intern assigned to the UOG Center for Island Sustainability and Sea Grant Science Communication team.

If there’s one thing that has always driven me, it’s my curiosity. I’ve always been the type of person who loves learning about new things. Staying curious about life and accepting the fact that I don’t know everything is one of those things that sustains me. It keeps me interested in the world around me and reminds me that there is always something new to learn.

After catching the wave of community opinion on ocean energy: Getting ready for the next BIG one

By Rico Lizama

Energy isn’t just a technical topic on Guam: it’s personal, talked about over kitchen tables, power bills, and weekend gatherings. As the Perceptions of Ocean Energy (POE) project winds down, I’ve been looking back at where this journey started: face-to-face with the people who call this island home. With this community-first mindset, between August and December 2024, I set up outreach tables across Guam to showcase our research and hear directly from community members about the future of ocean energy.
