The "No Fishing Allowed" sign notifies the public that the act of fishing in the given private pr public body of water is not allowed. Whether for reasons of health and safety, trespassing or conservation, the sign tells the individual to refrain from engaging in the act. The sign pictures a barred person fishing to provide visual representation of the unwanted behaviour.

The sign is best displayed on the railings of bodies of water where fishing is not allowed, or nearby, as to be visible.
