Atlantic salmon exposed to a common anti-anxiety drug migrate faster, according to new research. That's not necessarily a ...

A benzodiazepine seeping into waterways is causing young Atlantic salmon to behave strangely, with fish in the wild migrating ...

Scientists found that fish given an antianxiety drug reached their feeding grounds more often. But researchers warned of increasing pharmaceutical pollution.

When the researchers tracked the migrating salmon with transmitters, they found that more clobazam-exposed salmon reached the Baltic than any of the other fish. Compared with the control group, more ...

Instead, he and his colleagues essentially dumped pharmaceuticals into fish just before they were set to migrate from the River Dal in Sweden to the Baltic Sea. The team implanted slow-release drugs ...

Clobazam, a benzodiazepine used to treat anxiety, has been found to affect Atlantic salmon in similar ways to humans.

Pharmaceutical pollution can significantly affect wild animal behaviour, including speeding up salmon migration.

"While the increased migration success in salmon exposed to clobazam might seem ... in Sweden's River Dal as they migrated to the Baltic Sea. A follow-up laboratory experiment also found that ...

they found that more clobazam-exposed salmon reached the Baltic than any of the other fish. Compared with the control group, more than twice as many salmon with clobazam implants made it to the sea.

Clobazam seemed to boost the migratory success of the young salmon. More clobazam-exposed fish reached the Baltic than non-exposed fish, the researchers found. Tramadol appeared to have no effect.
