1. Example of swimming trajectories from three groups of fish from three different weeks along with the extracted behavioral parameters.
Example of swimming trajectories from three groups of fish from three different weeks along with the extracted behavioral parameters. Colored and gray paths indicate examples from the treated and untreated fish, respectively, where black is week −1, blue is week 1, and orange is week 4. (A) Swimming trajectories of each treated fish swimming with a group of normal untreated fish from the top view of the 3D constructed paths (scale bar, 10 cm). The circle indicates the edge of the experimental tank. (B) The nearest neighbor distance of each fish over time extracted from the trajectories shown in A. (C) The bearing angle with the nearest neighbor in the horizontal plane. (D) The elevation above or below the nearest neighbor. (E) The forward velocity of each fish in the group.
