Pike angler Eric Edwards found some added competition when he tried a new stretch of river in the shape of a family of otters.
As first the dog otter then its kits came out to play on the icy margins, he realised he'd pitched up close to their holt and moved on. There's little chance he'd have found a pike nearby.
But the sighting still made for a memorable day, as Eric observes.
"I was truly thrilled to see those otters and absolutely delighted to get pictures of them," he writes on his blog.
"There are those in the angling world who would have otters done away with but not me, they are a predator, just like the pike I want to catch and for too long predators have been persecuted. Better to make room for them and enjoy their presence in my view."
