“Drone fishing” is a relatively recent innovation in the use of unmanned aerial vehicles. Some recreational anglers are using personal drones to fly baited lines into hard-to-reach areas of water, or to look for good fishing areas.
Recreational fishing is a popular sport and hobby in South Africa, which has a 2,850km shoreline. The most recent estimate of the number of marine shore based anglers is about 400,000.
The group of researchers I’m part of, who study linefish (fish caught using hook and line) became aware over the past 10 years or so of the increased practice of drone fishing. This was in part thanks to recreational fishers approaching us with their concerns.
