Cold water systems

Our cold water aquaria system at Eawag, Kastanienbaum, contains 122 aquaria with a total volume of 33’000 L. More than half of the aquaria are connected to a flow-through system which provides the aquaria with a constant supply of fresh water from Lake Lucerne. The remaining aquaria are filtered with an air filter connected to a centralized compressed air system.
Our cold water aquaria vary from small 150 L rearing aquaria, up to a large 2250 L tanks. We also have many small aquaria which can be set up as required.
Additionally, we sometimes run experiments in the ponds and a basic aquarium system in the boathouses of the Ethological Station Hasli. The ponds are about 14.5x12m and up to 1.5m deep.
