A new study reports that Atlantic salmon exposed to the anti-anxiety drug clobazam during migration became bolder, passing through hydropower dams faster, though this behavior might increase predation risk later.

Salmon advocates have raised concerns over declining salmon numbers, blaming an oversupply of hatchery-reared fish that overwhelms natural stocks and disrupts ocean ecosystems.

An investigation into the death of roughly 100 fish near Alaska’s Kensington gold mine remains inconclusive months later, with both state regulators and Coeur Mining unable to pinpoint the cause despite extensive testing.

In recent years, researchers have documented salmon surviving in North Slope rivers, bowhead whales expanding their foraging grounds and humpbacks moving into the Arctic.
