Edwin Foekema, a researcher at Imares Den Helder, makes fun of his hobby: 'The hardest way to catch a fish.'
But the best way, in his view. 'It is far more satisfying than ordinary fishing', he says. The trick is to tempt the fish into taking the bait. So the artificial fly must land on the water as softly as a real one. A fine art. And that outsized bath duck? That is the bellyboat the fly-fisherman gets around in.
