The invention discloses a method for killing, preventing and controlling
alien species ampullaria gigas in a riverway, and relates to the technical field of
alien species prevention and control. According to the distribution position of the detected ampullaria gigas, a plurality of positions where the number of the ampullaria gigas is large are selected for putting
trapping cages, and bunchy aquatic plants are bound in the
trapping cages through ropes; and feeding a certain proportion of natural enemy organisms of the ampullaria gigas into the
trapping cage. The position, number and distribution of the ampullaria gigas are accurately recognized by using the unmanned aerial vehicle carrying the
laser radar, the
cost effectiveness is good, black carps are accurately put according to the volume of the trapping cage, resource waste caused by blind putting is avoided, the cost of the trapping cage and the bait is low, the overall cost is effectively controlled,
natural enemies are put after trapping, the ampullaria gigas capturing and killing efficiency is greatly improved, and the economic benefit is high. The
water quality and the aquatic plants are monitored regularly, the
ecology is restored in time, the ecological balance
recovery of the river channel is powerfully promoted, and a scientific, efficient and environment-friendly solution is provided for prevention and control of the ampullaria gigas.
