1. A method of using an unmanned aerial vehicle (UAV) comprising a housing, a processor, a positioning unit, a sonar unit, a launching unit and a fishhook unit in fishing, the method comprising:

  • manipulating the UAV to fly to a designated destination determined by the processor according to one of a received wireless communication and a preset program;

    adjusting the sonar unit to a predetermined height by the positioning unit;

    determining a coordinate corresponding to a signal detected by the sonar unit as a fishing region when the signal is consistent with a predetermined value;

    launching bait to the fishing region by the launching unit;

    releasing a fishhook from the fishhook unit to the fishing region;

    maintaining the sonar unit at the predetermined height after releasing the fishhook from the fishhook unit to the fishing region;

    andmanipulating the UAV to hover or return by the processor according to one of a received wireless communication and a preset program;

    wherein the step of adjusting the sonar unit to the predetermined height by the positioning unit comprises;

    applying a first sensor of the positioning unit to sense a tension on a wire which connects the sonar unit to the positioning unit;

    sending the tension sensed by the first sensor to the processor; and

    instructing the wire to stop or decelerate by the processor if the tension is less than a first threshold;

    wherein the step of adjusting the sonar unit to the predetermined height by the positioning unit comprises;

    applying a second sensor of the positioning unit to sense a distance between the sonar unit and the housing;

    sending the distance sensed by the second sensor to the processor; and

    instructing the wire to stop or decelerate by the processor if the distance is less than a second threshold.
