Surveillance is a key factor to ensure safety in various fields , here motivity of fishing boats in ocean/sea are monitored for illegal intrusion in other nations boundary. Hence an effective scheme is designed to overcome this threat with Global positioning system (GPS) which provides dynamic location of fishing vessel in water and microcontroller which competes on GPS and predefined boundary locations to determine whether the boat have crossed the border or not. If so the fisherman is alerted and the message is transmitted to nearby coast guard ships through RF signals at VHF (30-300MHz) range which covers wide area. On adumbrated the patrolling units can alert the fisherman from their position or if necessary the entire movement of the fishing vessel could be controlled remotely for trespassing. This measures fixes the cross boundary fishing problems between nations as the fisherman’s are unaware about their position in water.
