About the counter

The fish counter at Nävekvarn films the fish passing by, and an AI model identifies species and direction for each clip.

About the figures

Every fish passing is counted with its direction, up or down. Net is up minus down.

Species and direction are identified by an AI model when the clip arrives, and no person has reviewed the figures yet. Some fish may get the wrong species, and the same fish can pass several times. Reviewed results are confirmed in a report after the season.

The figures count from 10 Oct 2026.

Flow and water temperature are SMHI's modelled values for the river (Vattenwebb, S-HYPE), not measurements at the counter.
