While training on South Radar; my trainee was vectoring Aircraft X for a Visual Approach to ZZZ. Aircraft X was assigned various headings for the approach; and assigned 8;000 feet in accordance with the Minimum Vectoring Altitude that they were currently above. Aircraft X was observed descending to/through 7;000 feet and issued a climb to 8;000 feet. In the future; I will issue a low altitude alert and a climb to the appropriate altitude.
A TRACON Controller giving instruction reported an aircraft descended through its assigned altitude and below the Minimum Vectoring Altitude.
