A delayed release device for a buoy engaged with an underwater lobster trap operates with a first magnet securing a buoy, such that the buoy is tethered to a deployed lobster trap submerged in lobster harvesting regions of the ocean. A second magnet secures the first magnet based on a magnetic field, and a displacement actuator is in communication with the second magnet for retracting the magnet in response to a predetermined condition. Based on the condition, such as a time delay, the actuator moves the second magnet distal from the first magnet for releasing the buoy when the distance reduces the magnetic field sufficiently. The actuator may include a drive screw having a threaded engagement with the second magnet, such that the drive screw is responsive to rotation for retracting the second magnet.
