Description
Milan Říha and co-authors report a 2026 journal article on how a predatory fish finds its way home at night. Pikeperch in a large reservoir left a stable resting spot each night to hunt across wide areas. How fish navigate dark, murky water over long distances is poorly understood.
Using sound-based tracking tags, the team followed the adults' nightly trips. Fish returned reliably even after journeys of several kilometers lasting hours. From the very start of each return, they headed almost straight toward the refuge. Their swimming speeds stayed steady and their paths barely wandered. Final approach distances were tiny compared with the trip length, and fish showed no long searching near home. The authors say the pattern fits goal-directed navigation toward a fixed, remembered target.
