Dolphins still pilfer fish from nets laced with spicy stuff. Even more infuriating? They do a victory lap afterward. (via hakaimagazine)

Fishers around the world are desperate for a reliable way to stop dolphins from plundering their catch. Dolphins’ net burgling—known as depredation—costs fishers income, but it also puts dolphins at risk of injury and entanglement. Proposed solutions to finally win the battle of wits, such as using noisemakers or reflective camouflage, have come up short.

Yet after five months of test fishing with capsaicin-coated nets, the research team co-led by Maria Garagouni, a marine biologist at Aristotle University of Thessaloniki in Greece, faced a tough realization: their idea didn’t work. The bottlenose dolphins that interacted with their netsDespite the disappointing result, Garagouni says she was wowed by how adept the dolphins were at pilfering their nets.

“And then the victory laps!” Garagouni says. “The play afterwards, when there were young calves in the group—after they’d get their fill of fish—the young ones would go off and do leaps in the air, almost as if to burn off all this new fuel. If this was our livelihood, I think it would be the most infuriating element to watch. But for me, obviously, it was amazing.
