The North Rock exhibit of the Bermuda Aquarium, Museum and Zoo is undergoing “major restoration” to ensure its long-term safety and integrity.

The seams that hold in place the two large acrylic viewing windows at the 30-year-old feature have reached the end of their service life and replacing them is a complex but vital task, a Ministry of Public Works spokesman explained.

To safely replace the seams, the 140,000-gallon tank must be fully drained so that the two main windows can be carefully lifted out by crane, the seal replaced and the windows reseated.

The “significant project” will protect the structure for decades to come, the spokesman said.

Jaché Adams, the Minister of Public Works and Environment, added: “These important upgrades at the Bermuda Aquarium, Museum and Zoo demonstrate our government’s commitment to preserving Bermuda’s natural heritage and enhancing the visitor experience for generations to come.

“I am proud that we are investing in this iconic institution, ensuring that world-class care, safety and educational impact remain at the heart of BAMZ’s mission.”

The restoration process has started with the removal and relocation of everything in the exhibit, starting with corals and followed by the fish.

Depending on the species, animals will be temporarily housed in other aquarium exhibits or holding tanks, or released back into their natural habitats.

Throughout the process, care is being taken to ensure the animals’ health and welfare.

The main construction phase of the project is scheduled to take place between January and April next year.

BAMZ has also started work on a new habitat for Oscar, the resident American alligator.

The reptile’s new home — across the main walkway at the site — will feature a larger pond and surrounding area designed to enhance both the creature’s welfare and visitor experience.

The spokesman said that the move would also clear space for the creation of an expanded, upgraded playground for families to enjoy.

Mr Adams added: “I look forward to seeing the revitalised North Rock exhibit and the upgraded alligator habitat open to the public, serving both our island community and visitors with renewed pride and purpose.”

The BAMZ thanked the public for its understanding and support and invited visitors to continue exploring other exhibits and programmes in the months ahead.
