“Bringing the Waikīkī Aquarium into SOEST strengthens a powerful bridge between research, education, and community engagement—transforming it into a living laboratory where world-class science directly connects with the people of Hawaiʻi and the Pacific,” SOEST Dean Chip Fletcher said.

The move will integrate the Aquarium’s public education and service mission with SOEST’s marine life laboratory initiatives and research capabilities.

“As the state’s trusted window into Pacific marine life, the synergy created by anchoring the WaikĪkĪ Aquarium within SOEST will not only enhance the stewardship and research stories that the Aquarium is able to share with our community, but will provide even greater opportunities for our students to gain hands-on experience in marine husbandry and conservation,” Waikīkī Aquarium Acting Director Judith D. Lemus said.

The reorganization from the Office of the Provost is reported to be cost-neutral, with no additional funds or positions requested. Current employees at Waikīkī Aquarium will remain in their existing positions and structures, ensuring continuity of service for the public and the university community.

The aquarium will host a 122nd birthday celebration on March 19, from 9 a.m. to 2 p.m. The day kicks off with a community coastal cleanup followed by a suite of family-friendly activities.

A new chapter

Lemus brings a wealth of experience in marine facility management, research, and education. Lemus served for four years as the interim director of the (HIMB) within the University of Hawaiʻi at Mānoa (SOEST) and is currently the interim associate dean for academic affairs in SOEST. Her primary focus at the aquarium is on operational improvements and enhancing the institutionʻs role in education, marine conservation, collaborative research, and community engagement.

“Managing the Waikīkī Aquarium is about more than just animal husbandry; it’s also about our engagement with the public and contribution to conservation of Pacific species, and our role as a public outlet for Vlogٷ research,” said Lemus. “As we celebrate 122 years, we are not just honoring our history, but building the systems, facilities, and stories that will carry us through the next century.”

One major accomplishment under her leadership has been the successful return of Hōʻailona, the beloved Hawaiian monk seal, to his refurbished enclosure.

New and upcoming exhibits:

  • The Aquaculture Tank: In partnership with Biota, a local aquaculture company, this exhibit will feature fish and coral raised entirely in aquaculture facilities at the Oceanic Institute and Waikīkī Aquarium. This “no-collection” model highlights sustainable trade and will also showcase 3-D structures from HIMB researcher Josh Madin’s Lab that facilitate coral growth.
  • The Edge of Reef Redesign: Formerly an iconic outdoor exhibit, the Edge of Reef was dismantled to make way for a critical infrastructure project. A redesign is planned for this exhibit with support from Vlogٷ, the Vlogٷ Foundation, and the Friends of the Waikīkī Aquarium.
  • New Tank for Mullet and More: The large tank that previously featured mullet, a species revered in Hawaiʻi as a staple food and in loko ʻia (Hawaiian fishpond) aquaculture, is being dismantled to make way for a modern habitat. The new enclosure may house mullet and possibly other compatible species such as rays or sea turtles.
  • The aquarium is planning new collaborations with a variety of Vlogٷ faculty and labs to help bring their work to broader audiences.
  • AZA Accreditation: The aquarium is starting a Pathway Toward Membership program with the Association of Zoos and Aquariums, the gold standard in accreditation for zoos and aquariums, with the goal of achieving AZA accreditation for Waikīkī Aquarium in about 5 years.

Unomia stolonifera

Resource managers and leading marine invasive species experts from Hawaiʻi, Florida, and U.S. Territories recently gathered in Hawaiʻi for the Unomia Learning Exchange Workshop, a critical meeting focused on preventing and responding to new threats to coral reefs. During the workshop, organized by the Coordinating Group on Alien Pest Species (CGAPS) at the University of Hawaiʻi at ԴDz, participants shared knowledge and strategize against the spread of high-risk invasive species, particularly those stemming from the illegal release or outplanting of marine aquarium species, and high-risk coral diseases such as Stony Coral Tissue Loss Disease.

The event focused on the alarming rise of species originating from the marine aquarium trade, particularly a soft coral known as Unomia stolonifera. This species has rapidly overwhelmed reefs in Venezuela and has now been found in Hawaiʻi, where an eradication effort is underway. Similarly, Xenia umbellata, another popular aquarium soft coral, was recently discovered on reefs in Puerto Rico. These cases underscore the urgent need for a unified response to the illegal release of aquarium animals.

“The release of these species, whether intentional or accidental, poses a significant threat to our fragile marine ecosystems,” said Christy Martin, Program Manager for CGAPS, a project of the Pacific Cooperative Studies Unit, Vlogٷ Manoa. “This workshop provided a vital platform for experts to learn from each other’s successes and challenges. By sharing what we know, we can build stronger defenses to protect our reefs from these aggressive invaders.”

A key component of the workshop was a tabletop exercise where participants simulated a rapid response scenario to a Unomia detection. This exercise, which followed the Aquatic Nuisance Species Task Force guidelines, helped inform the development of comprehensive response plans for state and territorial waters. The workshop also previewed a new planning tool from the U.S. Geological Survey’s Species Invasion Rapid Response Information Network to help communities create their own early detection and rapid response plans.

Attendees also visited the Waikīkī Aquarium to get a firsthand look at live samples of invasive species like Unomia stolonifera. The Aquarium is a unit of the Vlogٷ ԴDz and is a partner in the state’s “Don’t Let It Loose” campaign, which educates the public about the severe consequences of releasing aquarium animals.

In Hawaiʻi, the possession or import of non-native marine aquarium animals requires a special permit that is not available to individuals or businesses and is a felony, with penalties that can include large fines and prison time. To provide an alternative, the Aquarium also serves as an official amnesty drop-off site where people can surrender illegal aquatic animals without penalty. Amnesty locations include Hawaiʻi Department of Agriculture and Biosecurity offices statewide.

The workshop was supported by a grant from the National Fish and Wildlife Foundation Coral Reef Stewardship Fund to the University of Hawaiʻi at ԴDz Pacific Cooperative Studies Unit, with additional support from the Hauʻoli Mau Loa Foundation and Bishop Museum. This collaboration highlights the critical role of partnerships in tackling complex environmental challenges and protecting the health of our oceans.

The number of fish to catch around Oʻahu got a small boost when a team including University of Hawaiʻi at Mānoa researchers released about 150 tagged pāpio (juvenile ulua or giant trevally) into waters around the island. Now, fishermen can help those researchers with important data by catching the tagged fish and reporting the information while also winning prizes. Fishermen can keep all of the pāpio they catch.

The pāpio were released on October 17–19 at four different locations around Oʻahu: , Kāneʻohe Bay, Pūpūkea Marine Life Conservation District and Pōkaʻī Bay.

Researchers hope to show on a small scale how raising and releasing the pāpio could offset fishing pressure and help rebalance the composition of the local reef fish populations if done on a larger scale in the future.

“What I hope this project achieves is bringing awareness to the concept of restorative aquaculture,” said Spencer Davis, a PhD student at Vlogٷ āԴDz’s (HIMB) and an employee of Oceanic Institute of Hawaiʻi Pacific University. “That fish can be grown from eggs collected from public aquariums and that those fish can be used to restore populations of wild fish.”

Researchers included four release sites around the island to mitigate any concerns about predator introduction or genetic impact. In addition, throughout the rearing to release process best management practices were integrated to mitigate any biosecurity issues. By releasing smaller cohorts of approximately 50 pāpio around Oʻahu, they hope to increase the number of fishermen that will have access to catch the fish later and gather recapture data. Each release site is located in regulated areas to allow time for the fish to acclimate to the wild before moving out into fishable zones.

“These releases provide a small enhancement to wild populations of ulua around Oʻahu with the intent to both restore the ecological structure of coral reef fish communities and provide recreational opportunities to local fishers,” said Erik Franklin, an associate research professor at HIMB and Davis’ advisor. “We’re planning to expand this program if we can identify future funding support.”

Partnering with local fishermen

Each tag is labeled with a unique fish identification number and a note instructing fishermen to call the researchers and report the date, capture location (general area, no need to give away your secret spots), length and weight of the fish. Nanko’s Fishing Supply is supporting the project with a raffle and prizes for participating fishermen at the end of the recapture period, approximately one year after the pāpio are released.

“We would love to find any of these released fish that end up being recaptured and reported by local fishermen,” said Davis. “We would learn about how much the fish grew in the wild, how far it traveled from the release location, and how likely fishermen are to recapture fish that are released as part of similar restorative aquaculture efforts.”

Originally, researchers received eggs from Maui Ocean Center in November 2022 and grew the eggs into the pāpio being released today. Franklin contributed funding provided by a local donor who supports research on recreational fishing to the for tagging the fish and transporting them for release.

Looking to future large scale efforts

A healthy ecosystem is composed of many species fulfilling key ecological roles such as predators, herbivores and scavengers. Fishing pressure has led to a decreased number of apex predators in waters around the main Hawaiian islands, especially Oʻahu. If any of the pāpio are recaptured, it will help researchers learn about how effective a larger scale restorative aquaculture effort can be in the future.

This project is a spin-off of previous work funded by the Center for Tropical and Subtropical Aquaculture. This collaboration includes efforts from: Waikīkī Aquarium; Department of Aquatic Resources; HIMB; Oceanic Institute of Hawaiʻi Pacific University; and Maui Ocean Center.

Baby weedy seadragon against a ruler

For the first time in its 118-year history, the has successfully bred a weedy seadragon, placing it among a small, select group of aquariums worldwide to breed this distinctive fish.

Found in Southern Australia and Tasmania, are in the family Syngnathidae and are relatives of seahorses and pipefishes.

“This is an incredible achievement for our team since starting our seadragon husbandry program 14 years ago,” said Andrew Rossiter, Waikīkī Aquarium director. “Weedy seadragons are notoriously difficult to breed in captivity, and we couldn’t be more excited.”

Like seahorses, male weedy seadragons brood the eggs; however, the eggs are incubated on the underside of the tail instead of in a pouch. Weedy seadragons perform an elaborate mating dance, spinning snout-to-snout and moving up and down in a water column to transfer the eggs from the female onto the male’s tail, where they are then fertilized.

Appropriately enough, the Waikīkī Aquarium’s weedy seadragons had a successful egg transfer just prior to Father’s Day on June 11, 2022. The male carried the eggs until the fully formed juvenile hatched on August 2. The baby seadragon has grown rapidly and is currently four inches in length and is being carefully monitored and cared for behind the scenes. Vlogٷors to the Waikīkī Aquarium can see this newest addition via a live camera feed located in the aquarium galleries.

The Waikīkī Aquarium has been administered by the University of since 1919.

ʻ has the lowest population of ʻDZ辱, endemic intertidal limpets, across the Hawaiian Islands. To help rebuild the population of this Hawaiian delicacy, two graduate students at the University of Ჹɲʻ at ԴDz (CTAHR) are attempting to spawn and rear ʻDZ辱 to adulthood in their lab on campus.

Angelica Valdez and Mitch Marabella are trying to complete the ʻDZ辱 life cycle. To do that, they would need to spawn and fertilize an ʻDZ辱 in the lab, grow that ʻDZ辱 so that it can reproduce, and transplant the offspring back into the wild.

“The dream goal is to get all the way through the life cycle,” said Valdez. “We’ve come pretty close. The 30-day ʻDZ辱 animal was the first where we’ve had records of shell growth. That is the longest we’ve had, it was really incredible that we got it that far.”

Spawn trials

To re-establish the population, Valdez and Marabella are conducting spawn trials in the lab, a process that can take up to 36 hours overnight. They start by introducing a peptide hormone to the ʻDZ辱 and place them into a spawning container. During that time they will record measurements and continue to check on the ʻDZ辱 every hour.

Peak spawning times are between midnight and 3 a.m. Once the ʻDZ辱 spawn, the students begin checking on the animals and the quality of the water and containers. One person counts the eggs while the other is fertilizing. After spawning, there is an 8–12 hour lull until researchers do a larval transfer before the grow out phase.

“When we do get a spawn, we have to really rush because ʻDZ辱 don’t have a protective shell around the egg so it is susceptible to polyspermy (when multiple sperm enter an egg),” said Marabella. “So we have to make sure it is properly fertilized, making our work much more active at night.”

So far, Valdez and Marabella have conducted 20 spawn trials. They have also partnered with the , which provides their lab with barrels of salt water for the ʻDZ辱. During a spawning trial, students go through up to 50 gallons of water.

Sustainable harvesting

Students are trying to get ʻDZ辱 to a viable stage where the reproduced ʻDZ辱 can be outplanted into the intertidal area of the seashore to build up the population again, so that people can harvest responsibly and sustainably.

“It’s a long process and that’s why it is harder to look toward farming at this point,” said Marabella. “We’re more focused on conservation right now because farming would not be possible if this population is decimated.”

Former CTAHR students began trying to re-establish the ʻDZ辱 population on ʻ in 2007. Since then, the project has been handed down to the next cohort of students. Valdez began working on the project in 2018 and Marabella joined the project in 2020.

“We never want to stop people from harvesting. It is a tradition with family and it is cultural to Ჹɲʻ,” said Valdez. “Our goal is to build back up the ʻDZ辱 population so that it is sustainable for everyone to harvest.”

The ’s iconic giant clam (Tridacna gigas) died of suspected natural causes on Tuesday, June 21. Acquired from a clam farm in Palau, the clam made its way to the aquarium about 30 years ago. Residing in the Barrier Reef exhibit, it soon became a guest favorite and grew to more than 200 pounds. Worldwide, it was the oldest of its species in captivity at more than 40 years old.

“Needless to say, we are all saddened at the demise of one of our flagship, and oldest, animals,” said Andrew Rossiter, director of the Waikīkī Aquarium. “The clam looked fine over the weekend, but showed a catastrophic decline on Monday, when it began releasing clouds of eggs into the exhibit. Unfortunately, despite the close attention of our staff, there is little that can be done when a clam falls ill. We have checked the parameters in the exhibit, and they have remained unchanged for at least the past year. We have sent tissue samples for analysis in case we missed something. However, Biology 101 tells us that the older the animal, the more-likely it is to die, and I expect its demise will be attributed to natural causes.”

Vlogٷ ԴDz students and LGBTQ+ Center Director Camaron Miyamoto were featured in the joint Vlogٷ video.

In recognition of International Transgender Day of Visibility on March 31, the partnered with the University of Hawaiʻi at ԴDz to produce a special educational video that celebrates the importance of gender diversity within human and marine life.

There are currently more than 500 species of fish that change sex throughout their lives, including clownfish, groupers and masked angelfish. The transformations can be triggered by age, size or social reasons.

“Gender change is normal, and it is something that we see in many species throughout nature,” said Camaron Miyamoto, director of the Vlogٷ ԴDz LGBTQ+ Center. “The purpose of this video is to showcase this and the fact that everyone is part of a natural environment and deserves to be truly affirmed for their sexuality, gender and sex.”

“We hope that this video educates the community about the importance of not only accepting but celebrating gender diversity. The absolute normalcy and neccessity of changing sex in many species is highlighted within the fish at the Waikīkī Aquarium. It is an honor to partner with the Vlogٷ ԴDz LGBTQ+ Center on this significant effort,” added Chessa Caparros, Waikīkī Aquarium volunteer program coordinator.

Founded in 2009, International Transgender Day of Visibility honors and celebrates the achievements, courage and resiliency of transgender individuals and communities. It raises awareness of the discrimination and barriers to equality the transgender community faces daily.

To further study the unique physiology and sensory biology of endangered Hawaiian monk seals, marine mammal scientists at the University of California Santa Cruz are partnering with Hawaiian zoological facilities and Sea Life Park on Oʻahu. The aquarium is a University of Hawaiʻi at Mānoa research facility.

Specialized research programs and marine mammal facilities available at University of California Santa Cruz’s Long Marine Laboratory have enabled several important studies to be completed with the species since 2009.

The next phase of research will include the return of 19-year-old Hawaiian monk seal KE18 from California to Sea Life Park where he will be featured in educational programming highlighting the endangered status of the species and the value of collaborative conservation research. Meanwhile, Waikīkī Aquarium will temporarily transfer 13-year-old male Hawaiian monk seal KP2 to the research program in California while the monk seal exhibit at the aquarium is updated and renovated.

“The Waikīkī Aquarium is grateful for this opportunity to work closely with the University of California Santa Cruz and its partners to support conservation efforts for Hawaiian monk seals and education about this endangered species,” said Andrew Rossiter, director of the Waikīkī Aquarium. “This will allow us to renovate our monk seal exhibit so we can continue to help in future research and protection efforts.”

KP2 previously spent several years at Long Marine Laboratory participating in cooperative research. His planned sabbatical will allow scientists to support ongoing studies of auditory biology and provide insight into how monk seal metabolism changes throughout development.

These studies support conservation efforts for wild monk seals by providing relevant biological data from non-releasable male monk seals trained to cooperate in scientific sampling. Such information is often difficult or impossible to gather from free-ranging seals. Measurements are obtained by animal care specialists without harm to seals, and research activities are monitored by the Institutional Animal Care and Use Committee.

Research with non-releasable Hawaiian monk seals is authorized by NOAA Fisheries. The planned research activities involving monk seals KE18 and KP2 are supported by the U.S. Navy’s Office of Naval Research and Living Marine Resources Program. Multiple agencies have participated in planning vaccination and quarantine requirements, including those related to COVID-19, to ensure the health and safety of people and animals.

This partnership is an example of Vlogٷ āԴDz’s goal of (PDF), one of four goals identified in the (PDF), updated in December 2020.
