Salmon migration affected by drug pollution in water from antianxiety medication
- Researchers reported in *Science* on April 10 that clobazam affects salmon migration behavior in Sweden.
- Benzodiazepines and opioids, found in rivers worldwide, accumulate in salmon brains, changing their behavior.
- Salmon with clobazam implants migrated faster past dams, but shoaling behavior was affected in lab experiments.
- Caudill noted that clobazam could make salmon two to eight times faster, but also vulnerable to predators.
- Michelangeli stated drug pollution poses risks, and further study will assess long-term impacts on salmon populations.
