Detection and visualization method of spatial trajectories of movement of water animals and apparatus for making the same The invented detection and visualization method of trajectory (1) of movement of water animals (2) is characterized by the use of a camera (7) that records a structured light and being situated below the container (4) with animals to be monitored. The container (4) has transparent bottom (10). Digital snapshots (5) of water animals (2), which appear as shape-stable objects (9) when viewed from beneath, are then used for determining the trajectory (1) thereof based on the shift of the object (9) centroid (13) within the appropriate time interval between making the separate snapshots (5). The invention also relates to an apparatus for making the above-described method.
