The center also has a series of natural water aquariums and terrariums that showcase fish and amphibian species found throughout Newfoundland and Labrador.

It was formed by a group of environmentalists and conservationists who were motivated to protect and enhance Rennie’s River, a major waterway flowing through the heart of St. John’s into Quidi Vidi Lake.

To clean up Rennie’s River, a series of projects were undertaken including stream stabilization, general environmental restoration, and construction of a fish ladder.

Since its inception, over 7.5 km of walking trails, including boardwalks and look-out areas, were completed along the banks of Rennie’s River and around Quidi Vidi Lake.

In 1985, the foundation also received approval by the St. John's City Council to build an interpretation centre at Long Pond with a stream tank to "allow visitors to view, through a glass wall, the surface and bed of the river, where they will be able to observe trout spawning.

A tributary of Rennie's River, this brook originates 3 kilometers north of The Suncor Energy Fluvarium, at Three Pond Barrens.

Research into the pigmentation of rainbow trout flesh using Rhodotorula in prepared diets was investigated in partnership with the Newfoundland and Labrador Institute of Fisheries and Marine Technology Aquaculture Unit.

In the late spring, classes go to The Suncor Energy Fluvarium to release salmon eggs into Nagle's Hill Brook.
