Zebrafish (Daniorerio) are commonly used, but other testspecies are also appropriate. bbe hasdeveloped a sensitive instrument for thedetection of toxic compounds in waterbodies such as rivers, water treatmentplant intakes and sewers. This instrumentis based on a development of theExtended Dynamic Daphnia Test (EDDT),a proven method used widely in Europeand other parts of the world.Continuous biological monitoring withthe bbe Fish Toximeter enables rapiddetection of toxic substances in waterand provides an online real-timewarning system. The relative magnitudeand duration of the presence of toxicsubstances is recorded by the instrumentto enable further analysis. This uniqueinstrument enables supervision andcontrol to detect, record and respondrapidly to incidents of toxic contamination. The Fish Toximeter is well-suited tothe detection of wilful or negligentdamage to water systems such as thedrinking water supply. The bbe FishToximeter is capable of long-termmonitoring during the “strategic”evaluation of water quality.Technology for water qualitymonitoringThe toximeter’s continuous visualanalysis of fish movement enables rapidThe bbe Fish Toximeter, an instrument with a wide detection rangeassessment of the fish’s behaviour andhealth.

An instrument for water toxicity monitoringHigh sensitivity – low maintenance costsThe bbe SoftwareThe integrated bbe software recognisessignificant changes in the behaviouraldata obtained from the live observationand recording of the fishs’ movements.Toxic events are clearly indicated as"alarms". A statistical approach enablesalarm recognition even under difficultreal-world conditions such as "noisy" orslow drift of the measured behaviouralcurve(s). The sensitivity of the alarm canbe pre-defined or easily adjusted by theuser based on the specific application.The bbe software is an approved systemand already used with other onlinetoxicity assessment systems.Screenshot of the bbe Fish Toximeter SoftwareSimple to OperateThe PC runs on Windows 2000/XP. Thebbe software contains all thecomponents necessary to operate thetoximeter. It provides a graphic controlpanel of the measured results with live,real-time images, offline viewing and anintuitive user interface. Fish tank, tubesand connectors are easily accessible at alow-maintenance level.Optionsconnection to a local area network with permanent access to dataremote maintenance of the computer systemremote or local automatic audio/visual alarm indicators via fax or pagerIntegratation of other sensors to measure oxygen, pH, conductivity, etc.standard size of the fish basin is 60 x 50 x 10 cm.Other sizes are available on request.Your local bbe dealer...Zebrafish (Danio rerio)
