Salmon Cam.

Phil Dalton of John Downer Productions used a fake salmon with a camera inside to record bears diving for salmon.

Each camera costs about £10,000 to develop and build, and Mr Dalton said several were damaged by the programme’s over-inquisitive subjects.

But apart from a impromptu swim downstream when it broke away from its fixings, the Salmon-cam survived relatively unscathed.

"Initially the bears gave it a lick and bite," Mr Dalton said.

"But when they realised it was not a real fish and didn’t taste of anything, they left it alone."
