AI sorter for small pelagic fish
An AI vision system that recognises and sorts sardines and anchovies on the conveyor.
Sardines and anchovies look very similar, and at full belt speed the human eye often gets it wrong. Our sorter captures every fish with a camera, an AI model recognises its species and position in real time, and the control logic fires air nozzles at exactly the right moment to separate it.
How it works
1. Camera
Captures every fish passing on the conveyor.
2. AI model
Recognises the species and position of the fish in real time.
3. Nozzles
Control logic fires the air nozzles at the right moment.
Results
99.1%detection accuracy (mAP@50)
99% / 98%of sardines / anchovies classified correctly
14–18kfish per hour per line at 1 m/s (tested)
25,000+labelled images from a real conveyor used in training
Measured on a separate test set. Capacity depends on belt speed and fish density (4–5 fish per metre).
What else is possible
- Sorting by length, with millimetre measurement of every fish
- Detecting and removing damaged or low-quality fish
- Extending the model to additional fish species
- Counting, species shares, reports and statistics in real time
Ready for your line
- Connects to your air nozzles and PLC
- Runs on an industrial PC
- A short adaptation on your fish tunes it to your conditions
