An illustration of how light changes visual hunting range during Day, Dusk, and Night
Detailed Description
An illustration of how light changes visual hunting range during Day, Dusk, and Night. Fish deeper in the water column, where light levels decrease, lose visual hunting range. As daylight levels reduce into Dusk and Dawn, visual hunting ranges decrease. Artificial light at night has shifted the darker night-time environment into more of a perpetual twilight (Dusk) condition that coincides with higher predation.
