Underwater windows can be utilized in rivers to observe migration of fish.

Pump stations nowadays need to be fish friendly. This can be achieved by building a fish ladder. A fish ladder, also known as a fishway, fish pass or fish steps, is a structure around dams to facilitate fishes’ migration.

Typically, the observation windows are integrated into the ladder. Here, the fish are forced into narrower streams. The fish will need to swim close to the window, which makes observation easier. The structures consist mainly of concrete.

Hydrosight offers industrial type underwater windows of the type Water Stop.

Monitoring fish migration is enabled by supervisory underwater windows, such as currently planed in the city of Antwerp in Belgium (2014).

Hydrosight build an underwater window for a fish ladder for United Concrete, a company from Connecticut, USA (2012).
