The Institute of Marine Science, Burapha University
The Institute of Marine Science, Burapha University, also colloquially known as the Bangsaen Aquarium, is one of Thailand's oldest and most renowned aquaria. It is located within Burapha University, Chonburi province, near the beach of Bangsaen.
The aquarium has been operating since the 1980s. At the entrance to the exhibition hall, visitors can see the skeleton of a Bryde's whale found in the Gulf of Thailand on display.
Inside, the exhibition area is divided into several zones, including an economic fish zone, an ornamental fish and sealife zone, and a jellyfish zone. The jellyfish are showcased in tanks with bioluminescent displays that change colors according to the lighting. Microscopes are available for visitors to observe jellyfish stinging cells, and video presentations explain the feeding behavior of jellyfish ephyrae, with staff on hand to provide guidance.
A key highlight is the large tank exhibiting various large coral reef fish species, such as the giant trevally, barramundi, mangrove jack, giant grouper, zebra shark, and round ribbontail ray. At 2:00 PM, there is a feeding session where food is dropped from above, and stepped seating is provided for visitors to watch.
Another highlight is a newly opened zone in a separate building that opened on December 5, 2022. This zone displays shallow water fish, mangrove fish, and brownbanded bamboo shark mermaid's purses, which have been successfully bred in captivity. The exhibition is designed like an art gallery, with visitors walking down to the lower level where a large cylindrical tank, standing tall, and an acrylic tunnel that gently spirals downward, giving visitors the feeling of walking under the sea. This immersive underwater walkway stretches and ends with a long flat escalator that gently takes visitors back to the surface. Fish displayed here are similar to those in the large tank, with additional species such as the tawny nurse shark and shovelnose ray. The feeding session by divers also takes place at 2:00 PM in this zone.
The institute was the first in the world to successfully breed clownfish in captivity, and it offers knowledge and consultation to farmers interested in commercial breeding as well as to individuals wishing to keep marine animals as pets.

Admission fees are 80 baht for adults and 40 baht for children, while foreign visitors are charged 220 baht for adults and 120 baht for children.
