Pure Aquatics was commissioned by Wild Life Sydney Zoo to design and construct a specialised breeding laboratory for the endangered Littlejohn’s tree frog. The project required a highly controlled environment capable of supporting both adult frogs and tadpole development, while accurately replicating natural habitat conditions.

The facility was designed to accommodate the full lifecycle of the species, integrating custom tank systems that allow for variable water levels and seamless transition between aquatic and terrestrial phases. This flexibility is critical for supporting breeding behaviours and ensuring successful development at each stage.

Water quality management was a key component of the system. Pre-filtration ensures all incoming water is free from contaminants before entering the system, while a fully recirculating filtration system maintains consistent water quality across all tanks. This approach reduces risk while ensuring stable environmental conditions.

Environmental control systems were central to the design. Precision misting systems regulate humidity, while temperature control and specialised UV lighting replicate natural environmental cues. These elements work together to stimulate breeding behaviour and create a stable, low-stress environment.

The completed facility delivers a highly controlled and adaptable breeding environment, supporting conservation outcomes and demonstrating Pure Aquatics’ ability to integrate biological understanding with advanced engineering design.
