Salmon made to leap through water

Salmon can be artificially stimulated to leap through water, scientists have shown for the first time.

Researchers kept the fish away from the water’s surface with a net barrier for a day. Following this, more than 90% of salmon would jump several times through the surface in the two hours following the barrier’s removal.

The discovery is a precursor to an effective sea lice treatment, an infection that costs the global industry more than $500 million each year,

By inducing salmon to jump at intervals that are predictable, researchers can ensure the surface treatment method is effective.
