The movement behavior is an essential expression of life events of animals for survival (e.g., foraging, escaping).Various computational methods for analyzing motions of animals are outlined to address response behaviors of indicator animals under chemical stress.In this study, the Fractal Dimension (FD) and the Permutation Entropy (PE) were investigated to demonstrate behavioralchanges before and after the treatments.The methodologywas tested on 40 individuals of Zebrafish(Daniorerio), (20 control and 20 treatment fish (Diazinon, 1ppm) which was showed that FD and PE are variable before and after the treatment.The behavioral changes were accordingly obtained to reveal dynamic processes in continuous movement. FD and PE were promisingtools for addressing structure property in response behavior of animals and could serve as an in situ monitoring tool to detect stressful agents in environment. Key words: Behavior monitoring,fractal dimension, permutation entropy, zebrafish, chemical stress.
