The influence of light on the diel vertical migration of young‐of‐the‐year burbot Lota lota in Lake Constance
The diel vertical distribution of young‐of‐the‐year (YOY) burbot Lota lota in the pelagic zone of Lake Constance was compared to light intensity at the surface and to the light intensity at their mean depth. Lota lota larvae inhabited the pelagic zone of Lake Constance from the beginning of May unti...
