Autonomous bird abatement drones
The European aquaculture industry produced 1.37 million tonnes of fish in 2017 with a total market value of €5.06bn.[1,2] The worldwide industry is growing by almost 7% annually, yet aquaculture firms can lose up to 15% of their fish to predator birds.[2,3,4]
Currently, physical barriers such as nets or wire cables are used to cover the surface water of the pens, but these are limited in their effectiveness and can be expensive to install and maintain.[5,6,7] In case of high losses, birds are shot - but this is environmentally unstabling, and many birds are also protected.[8,9]
Birds can also be scared away by light, pyrotechnics, and predator sounds. But birds can also acclimate to these, and so they need to be moved aggressively around to remain effective.[8,9] Incorporating such techniques onto one or several autonomous drones could further protect fish farms. Demonstrations have shown that a 10-minute mission can scare birds away for over 2 hours. Furthermore, autonomous abatement can be initiated when birds are detected nearby, and mimicking the bird’s natural enemy - such as drones with flapping wings - could introduce an additional fear factor, thereby increasing the effect.
When will autonomous drones be installed at fish farms to protect against birds?
