In Norway, whale steaks, sushi and burgers have been promoted at food and music festivals as modern and trendy, luring in younger consumers.

Whales are not just consumed, the carcass is being turned into cosmetics, vitamin supplements and protein powder.

“So far these marketing approaches have not really worked," said Truls Gulowsen, the head of Greenpeace Norway.

"The national and international demand for whale products is very, very small."
