July 20, 2026 — Counting salmon in Alaska has been done the same way since the 1950s.
A field biologist climbs a tower, counts the number of fish swimming through the area every 10 minutes on the hour, hops down and into a skiff, moves to the opposite bank, and counts for another 10 minutes. They then spend 40 minutes reporting that data – just to do it all again the next hour.
