Would it not be possible to create a closed loop for them to endlessly swim up? Sort of like a lazy river at a water park, but with a stronger current.

- hanniabu 7y agoYou certainly could create circular containments with directional flow.
- derefr 7y agoI’m not sure how salmon specifically would react, but migratory animals generally don’t get fooled by these sorts of things. (I don’t think anyone knows the mechanism, as not all migratory species have internal compasses like migratory birds do. But they do it anyway. Maybe it’s just really good dead reckoning?)
