Illegal, unreported and unregulated (IUU) fishing represents a critical threat to marine ecosystems and the legal economy. To combat it, a solution based on 3D technologies emerges: the authentication of fishing nets through photogrammetry and scanning. This system allows creating a unique digital fingerprint for each net, linking it to fishing licenses and authorized operating zones, facilitating the inspection work of compliance authorities.
Technical workflow: from net to digital twin 🛠️
The process begins with scanning the mesh using high-resolution 3D sensors or photogrammetry with drones in ports. Variables such as mesh eye size, thread thickness, knot pattern, and wear are captured. The modeling software reconstructs a digital twin of the net, assigning it a cryptographic hash linked to a regulatory database. During inspections at sea, agents use portable scanners to compare the physical mesh against its record. If the pattern does not match the vessel's license or shows alterations (such as smaller meshes to catch juveniles), the system automatically alerts, generating valid digital evidence for sanctioning processes.
Digital compliance and marine ecosystem protection 🌊
This technology transforms fisheries control by eliminating dependence on subjective visual inspections. For compliance departments, it represents a forensic traceability tool that integrates 3D data with license and satellite records. Beyond sanctions, the system deters the manipulation of fishing gear and protects vulnerable species. Adopting this authentication not only complies with international regulations but also reinforces the sector's sustainability, demonstrating that 3D innovation is a strategic ally in the fight against environmental crime.
How can 3D scanning of fishing nets become valid digital expert evidence in courts to certify the chain of custody in illegal, unreported and unregulated fishing crimes?
