Fish in study can be identified based on their movement and behaviour
This finding was based on research by a team of biologists and mathematicians from Swansea University and the University of Essex. It involved 15 three-spined stickleback fish observed individually in a fish tank containing two, three or five plants in fixed positions.
Using high-resolution tracking data from video recording, the scientists made their observations on the following parameters: movement (time stationary, step length, turning angle and burst frequency) and behaviorial (distance travelled, space use, time in free water and time near objects).
