A new outdoor exhibit tucked behind Surge Zone near the entrance of Maui Ocean Center will introduce visitors to four types of Hawaiian limu, complete with educational signage, when it holds its grand opening at 9 a.m. next Thursday, Nov. 12. The debut kicks off a full day of limu-related programming at the aquarium, from a free evening talk to a limited-edition shave ice flavor made with limu grown on site.
What the Exhibit Shows Visitors
According to Maui Now, the exhibit is included with regular aquarium admission, and Maui Ocean Center is open daily from 9 a.m. to 5 p.m., with last entry at 4 p.m. The aquarium describes the display as an outdoor exhibit meant to introduce guests to different species of Hawaiian limu, their traditional uses and cultural importance, and their role in the marine environment, per Maui Ocean Center. Limu is the Hawaiian word for many types of marine algae found in Hawaiʻi's waters, the aquarium notes.
Maui Ocean Center's education director, Tiara Fernandez, said limu is much more than seaweed, noting that its species are adapted to specific habitats and environmental conditions, the station's report states. The aquarium adds that limu provides food and habitat for marine life and contributes to healthy coastal ecosystems, helping sustain the balance of Hawaiʻi's nearshore waters.
Seeding Restoration Across the Island
Beyond the display case, the aquarium's curatorial team plans to grow limu for display, education and replanting efforts in Maui waters, per Maui Ocean Center. General Manager Tapani Vuori said community groups will eventually be able to come in and pick up seed stock from the exhibit and start restoration efforts around the island, according to the same account. Future plans include adding more limu varieties and, in time, developing a dedicated seed stock for restoration work, the report notes.
That ambition echoes broader concern over Hawaiʻi's shrinking limu supply. Limu gatherers interviewed by Hawaiʻi Sea Grant reported that shoreline limu has declined over the past two decades, with the organization pointing to urbanization, improper harvesting and shifting ocean conditions tied to climate change as the main culprits. Similar grassroots efforts exist elsewhere in the islands — the Waimānalo Limu Hui has hosted monthly community planting events in Waimānalo Bay since November 2017, drawing roughly 75 participants at a time, per Hawaiʻi Sea Grant.
Grand Opening Day Plans
On opening day, Maui Ocean Center will offer kamaʻāina admission pricing of $15 for adults and $10 for keiki, per Maui Now's reporting. Ke Kīpuka Limu and the Waimānalo Limu Hui will lead hands-on educational activities and cultural experiences at the aquarium throughout the day, while Seascape at Maui Ocean Center will serve a limu lunch special. Ululani's Hawaiian Shave Ice, located at the aquarium, will debut a gourmet limu pālahalaha flavor featuring limu grown at the center.
In the evening, the Sphere Theater will open at 5:30 p.m. ahead of a free 6 p.m. educational talk spotlighting limu specialists and aquaculturists, with attendees able to reserve a seat by signing up online. The following day, Friday, Nov. 13, the nonprofit Lele Aloha will host a limu restoration project in Lahaina, extending the week's focus on limu beyond the aquarium's grounds.
A Wider Restoration Movement
The Maui exhibit joins a handful of other limu restoration efforts underway across the state. Hawaiʻi Sea Grant and the company Symbrosia launched a limu kohu restoration partnership backed by a $500,000 grant from the National Oceanic and Atmospheric Administration, aiming to restore the native seaweed at selected locations across Hawaiʻi alongside community organizations over a two-year span running through 2026, according to Hawaiʻi Sea Grant.
On Lānaʻi, a long-running restoration project has worked since 2009 to re-establish healthy limu on the island's north-shore reef, where it was once abundant, according to a University of Hawaiʻi project page. Volunteers there have experimented with growing limu in aquariums, backyard barrels and tanks, and reef cages, with work that includes propagating limu, collecting water samples, measuring growth and maintaining a beachside site. Separately, four newly discovered Hawaiian red algae species were given Hawaiian names and had their scientific descriptions published in August 2022, the university reported.
