The Georgia Aquarium acquired its first whale sharks in 2006 through a partnership with the Okinawa Churaumi Aquarium in Japan

The Georgia Aquarium in Atlanta opened in 2005 as the world's largest aquarium by volume. Within its first year, the facility made a major decision: it would become home to whale sharks, the world's largest fish. The aquarium worked directly with the Okinawa Churaumi Aquarium, which had successfully kept and bred whale sharks in captivity for years. This partnership was crucial because whale sharks had never been housed in a U.S. aquarium before, and the informed needed to care for them was limited to a handful of facilities worldwide.

In 2006, the Georgia Aquarium received its first four whale sharks: two males and two females. The animals were transported from Okinawa to Atlanta in specially designed tanks that maintained proper water conditions during the journey. This was not a straightforward purchase or trade—it was a carefully negotiated arrangement between two major institutions that understood the complexity of moving and caring for such massive animals.

Key Takeaways

  • The Georgia Aquarium partnered with Japan's Okinawa Churaumi Aquarium, which had the only proven experience keeping whale sharks alive in captivity.
  • Four whale sharks arrived in 2006, making the Georgia Aquarium the first facility in the United States to house these animals.
  • The aquarium built a massive tank called the Ocean Voyager, designed specifically to meet the whale sharks' space and water quality needs.
  • Whale sharks in the wild are difficult to capture and transport, so the Georgia Aquarium's animals came from facilities that already held them rather than from the ocean.

Why the Georgia Aquarium chose whale sharks

The Georgia Aquarium's leadership wanted to create exhibits that would draw visitors and also serve a conservation purpose. Whale sharks are endangered in the wild due to fishing, ship strikes, and habitat loss. By housing them in a major U.S. aquarium, the facility could educate millions of visitors about these animals and fund research into their biology and behavior.

The aquarium also had the financial resources and technical capability to build the necessary infrastructure. Whale sharks are filter feeders that can grow to 40 feet long and require enormous tanks with constant water circulation, precise temperature control, and specific food sources. Few facilities in the world could meet these demands, which is why the Georgia Aquarium's decision to pursue them was significant.

The Ocean Voyager tank and its design

To house the whale sharks, the Georgia Aquarium constructed the Ocean Voyager exhibit, one of the largest acrylic-paneled tanks ever built. The tank holds 6.3 million gallons of water and measures 100 feet long, 78 feet wide, and 30 feet deep. This size was necessary because whale sharks are active swimmers that need room to move naturally. A tank that is too small can cause stress and health problems.

The tank's design includes multiple levels of filtration and water circulation systems to maintain the exact conditions whale sharks need. The water temperature is kept between 72 and 78 degrees Fahrenheit, and the tank is stocked with live fish that the whale sharks eat. The acrylic panels are thick enough to withstand the pressure of millions of gallons of water while remaining transparent so visitors can view the animals.

How whale sharks were transported from Japan

Moving a whale shark across the Pacific Ocean required specialized equipment and informed. The animals were placed in large transport tanks filled with seawater that was continuously monitored and treated. Oxygen levels, temperature, salinity, and pH had to remain stable throughout the journey, which took several days.

The Okinawa Churaumi Aquarium provided staff who traveled with the whale sharks to monitor their condition. The Georgia Aquarium's team coordinated with veterinarians, marine biologists, and logistics specialists to may support the animals survived the transport. This level of coordination is standard for moving large marine animals between facilities, but it is expensive and carries real risk—not all animals survive the process.

The role of international aquarium partnerships

The Georgia Aquarium could not have obtained whale sharks without the Okinawa Churaumi Aquarium's willingness to share knowledge and animals. International partnerships between major aquariums are common in the zoo and aquarium world. These partnerships allow facilities to exchange animals, share breeding programs, and transfer informed about caring for rare or difficult species.

The Okinawa facility had been keeping whale sharks since the 1980s and had learned through trial and error how to feed them, maintain their health, and manage their behavior in captivity. This knowledge was invaluable to the Georgia Aquarium, which would have faced much higher risk and cost if it had attempted to care for whale sharks without guidance from an experienced facility.

Breeding and population management at the Georgia Aquarium

Since 2006, the Georgia Aquarium has maintained a small population of whale sharks. The facility has not successfully bred whale sharks in captivity—breeding these animals in tanks remains extremely difficult and has only been achieved a handful of times worldwide. Instead, the aquarium focuses on keeping its current animals healthy and using them for research and education.

The whale sharks at the Georgia Aquarium are part of a broader network of facilities that share information about whale shark care. If one facility develops a new feeding technique or discovers something about whale shark behavior, that information is shared with other aquariums. This collaborative approach helps may support that all captive whale sharks receive the best possible care.

What happened to the original whale sharks

The four whale sharks that arrived in 2006 did not all remain at the Georgia Aquarium indefinitely. One of the original animals, a female named Trixie, died in 2007 after less than a year in captivity. Her death was attributed to an infection and raised questions about whether whale sharks could survive long-term in captivity.

The remaining animals continued to live at the aquarium. Over the years, the facility's collection of whale sharks has changed as animals have been transferred to other facilities or have died of natural causes. The Georgia Aquarium continues to house whale sharks as of now, though the specific individuals and their numbers have shifted since the original 2006 arrival.

Frequently Asked Questions

Did the Georgia Aquarium catch whale sharks from the wild?

No. The whale sharks came from the Okinawa Churaumi Aquarium in Japan, which had been keeping them in captivity. Capturing whale sharks from the wild is difficult, stressful for the animals, and raises conservation concerns. Transferring animals between aquariums is the standard practice in the industry.

How much did it cost to get the whale sharks?

The exact cost was not publicly disclosed, but moving and housing whale sharks is extremely expensive. The transport alone costs hundreds of thousands of dollars, and building the Ocean Voyager tank cost tens of millions. The ongoing care, feeding, and medical treatment of whale sharks also costs hundreds of thousands of dollars per year.

Can whale sharks survive in captivity?

Whale sharks can survive in captivity, but they do not thrive as well as they do in the wild. Some animals have lived for many years in aquariums, while others have died within months. The Georgia Aquarium's experience shows that survival depends heavily on tank design, water quality, feeding practices, and veterinary care.

Are there whale sharks at other aquariums in the United States?

The Georgia Aquarium was the first U.S. facility to house whale sharks, and for many years it was the only one. Other aquariums have since acquired whale sharks, but they remain rare in captivity in the United States. Most whale sharks in captivity are housed in Asia, particularly in China and Japan.

Why does the Georgia Aquarium keep whale sharks if they are endangered?

Aquariums argue that housing endangered animals serves conservation by educating the public, funding research, and maintaining genetic diversity in case wild populations decline further. Critics counter that captive breeding and long-term survival remain unproven for whale sharks. The Georgia Aquarium's position is that the educational and research benefits justify the effort.
