Continuous visual analysis of fish behaviour

The new bbe Fish Toximeter

A powerful instrument for water toxicity The advanced bbe Fish Toximeter

observes fish under the influence of a

"sample" water stream. Zebra fish (Danio rerio) are commonly used, but other test species are also appropriate. bbe has developed a sensitive instrument for the detection of toxic compounds in water bodies such as rivers, water treatment plant intakes and sewers. This instrument is based on a development of the

Extended Dynamic Daphnia Test (EDDT), a proven method used widely 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 an online real-time

warning system. The relative magnitude and duration of the presence of toxic substances is recorded by the instrument to enable further analysis. This unique The new bbe Fish Toximeter, an instrument with a wide detection range instrument enables supervision and

The bbe Software

The integrated bbe Software recognises significant changes in the behavioural data obtained from the live observation and recording of the fish’s movement.

Toxic events are clearly indicated as

"alarms". A statistical approach enables alarm recognition even under difficult real-world conditions such as "noisy" or slow drift of the measured behavioural curve(s). The sensitivity of the alarm can be pre-selected and adjusted by the user based on the specific application. The bbe software is an approved system and already used with other online toxicity assessment systems.
