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.
