A warning, with wildlife in mind.
A buoy concept combining predator recognition with a proposed non-lethal response to human–wildlife conflict near the coast.
Detection is the start of the response.
The buoy concept begins with observations of marine predators near coastal activity.

Evidence from the paper
- Shark species
- 14
Species covered by the reported recognition study.
- Reported accuracy
- 92%
Collective pattern-recognition accuracy in the paper’s abstract.
- Design intention
- Non-lethal
A biology-informed decoy concept, also considering saline crocodiles.
Source: IEEE IDCIoT 2023 and the author’s SSRN manuscript. Recognition accuracy does not demonstrate that a buoy can reliably deter animals or protect swimmers in real coastal conditions.
Detection is the first question
The study proposes recognising sharks and saline crocodiles as part of a coastal buoy system. It reports collective pattern-recognition accuracy of 92%, covering 14 shark species alongside crocodiles.
What should happen after a detection?
The design pairs recognition with a decoy mechanism informed by animal behaviour. The intention is a non-lethal response to coastal conflict. That makes the response mechanism as important a research question as the classifier.
From concept to coastline
The published work is a proof of concept. A classification result is one piece of the system: sea conditions, false alarms, maintenance, and the animals’ actual responses would need separate field evaluation. The diagram here explains the concept without presenting it as deployed coastal infrastructure.
