Video-Aided Analysis of Zebrafish Locomotion and Anxiety-Related Behavioral Responses

Due to physiological and anatomical similarities to other vertebrates, zebrafish are becoming a widely used model in neurobehavioral research. With the growing popularity of zebrafish as experimental subjects, it is important to develop tools that accurately record their behavioral phenotypes. Video-aided analysis of zebrafish behavior offers an increased spectrum of behavioral endpoints, some of which are not available using traditional (manual) observation. In addition, the use of computer software allows quantification of certain zebrafish behaviors that are otherwise highly subjective. This protocol describes a method for fast, accurate, and consistent video-aided measurements of zebrafish locomotion and anxiety-related behavior.
