Fish Toximeter Real-Time Biomonitoring


Continuous analysis of fish behavioural patterns for the detection of toxins in water.

The bbe Fish Toximeter observes the behaviour of fish in a tank under the influence of a stream of "sample" water with the aid of a camera and continuous computer-assisted image analysis. This uncomplicated but highly sensitive instrument is designed to detect toxic substances in e.g. rivers, reservoirs, water supply systems, water treatment plant intakes and sewers.

The instrument is based on the development of Extended Dynamic Daphnia Tests (EDDT), a tried and tested detection method in Europe and other parts of the world. Continuous biological monitoring with the bbe Fish Toximeter enables rapid detection of toxic substances in water and provides a real-time, online early warning system.

This unique instrument enables the user to observe and analyse toxic contaminations, record them and react quickly to them. The bbe Fish Toximeter is well-suited for the rapid detection of wilful or negligent damage to water systems. It is also conceived as a long-term monitor of water quality during "strategic" analysis.
