An Australian man has been fined $18,000 (€11,900) for killing a juvenile great white shark by ramming it with his boat and then beating it to death with a metal pole.
Great whites are a protected species in Australia and it is illegal to catch, keep, buy, sell, possess or harm them.
The New South Wales Department of Primary Industries took action against the man, 40-year-old Justin Clark, after witnesses told fisheries officers he used his boat to herd the shark into shallow water in Sussex Inlet, south of Sydney, in January 2012.
Wollongong Local Court heard that he deliberately used his boat to ram the shark several times, with its main injuries caused by the propeller.
A rope was tied to the shark's tail and it was towed back to a boat ramp, where the department said it was beaten to death with a metal pole.
Department of Primary Industries director of fisheries compliance Glenn Tritton said the fine was a warning to others.
"This conviction sends a strong message that harming of our threatened species will not be tolerated: everyone needs to know the rules and ignorance is no excuse," he said.
"Great white sharks are found along the NSW coastline and as apex predators at the top of the food chain, they play an important role in marine ecosystems."
Sharks are common in Australian waters.
They rarely prove fatal to humans, with only one of the average 15 attacks a year typically resulting in death.
In recent weeks, thousands of people have rallied around the country in protest at a controversial shark culling policy in Western Australia.
It allows sharks longer than 3m caught on bait lines off popular west coast beaches to be killed after six fatal attacks in the past two years.
The policy is designed to reduce risks to water users but has angered conservationists, who claim it flies in the face of international obligations to protect the great white.
