The Stepwise Behavioral Responses of Medaka (Oryzias latipes) to Organophosphorus Pesticides in an Online Monitoring System

The stepwise behavioral responses (SBR) of medaka (Oryzias latipes) were continuously monitored by an online monitoring system (OMS) after exposure at low concentrations of Trichlorfon (T), Parathion (P) and Malathion (M).

Description
Summary:The stepwise behavioral responses (SBR) of medaka (Oryzias latipes) were continuously monitored by an online monitoring system (OMS) after exposure at low concentrations of Trichlorfon (T), Parathion (P) and Malathion (M). The Self-organizing map (SOM) was used to train behavior strength (BS) measured by OMS according to different chemicals and concentrations. Behavioral difference was observed according to different levels of concentrations, and some differences were observed according to chemicals and concentrations. Differences in photo- and scotophases were also observed in control and treatments with lower concentrations and short exposure at high concentrations. Meanwhile, the changes of BS demonstrated SBR model correctly. SBR of medaka would be useful for presenting behavioral states in responses to treatments. The SBR model supported and developed the Stepwise Stress Model (SSM), which included No effect, Stimulation, Acclimation, Adjustment (Readjustment) and Toxic effect.
