The remotely actuated marker buoy is releasably tethered to, or immediately adjacent to, a maritime animal trap (e.g., crab trap, lobster pot, etc.) or other submerged object requiring recovery. The operator (fisherman, etc.) uses a transmitter to send a signal to a receiver at the trap to release the buoy when trap recovery is desired. The buoy is tethered to the trap, enabling the fisherman to sight the buoy when it rises to the surface and thus recover the trap by drawing up the tether. The transmitter may include an authentication code requirement to prevent another party from recovering the trap if the transmitter is stolen. The system may include a reply transmitter at the trap to provide a signal if the trap is empty and cancel the release of the buoy. The operator may override this recovery cancellation, if desired.
