Automatic classification · Marexi

The first system to automatically classify tuna by species and size.

Tunascan® combines 3D laser profilometry and artificial intelligence to identify, weigh and classify tuna without human intervention. Over 95% species accuracy and 98% weight accuracy. Up to 50 tonnes per hour.

Tunascan® — automatic tuna classification system
How it works

Three stages. Zero human intervention.

Stage 01

Feeding & alignment

Tuna of mixed species, sizes and condition is discharged into a hopper. Transport elements separate and align each fish for individual scanning, regardless of the presence of ice or frost.

Stage 02

3D scanning with AI

The system scans each fish individually using 3D laser profilometry, converting it into a point cloud. AI algorithms and neural networks process the data to determine species, size and weight with industrial-grade precision.

Stage 03

Automatic classification

The operator defines the classification criteria and the system autonomously assigns each fish to its container. Results integrate in real time with the plant's ERP for full traceability and production control.

Key features

Built for the tuna industry.

World first

The only system capable of simultaneously classifying tuna by species and size at industrial scale.

Industrial environment

Designed and tested in high humidity and salinity. Not affected by ice or frost typical in tuna handling.

ERP integration

Connects to the plant's ERP for real-time production control, full traceability and automatic batch reporting.

Adaptable to any plant

Highly adaptable to each facility's specific layout. Built with high-quality, internationally recognised components.
