Hvor mange havørreder gyder i Villestrup Å? Det har DTU Aqua undersøgt siden 1999. I december 2016 udførte man den sidste undersøgelse for at se effekten af, at spærringerne i åen er fjernet. Resultatet var overvældende.
How many sea trout spawn in the River Villestrup in Denmark after the impoundments have been removed and the river restored to its former glory? The answer: almost too many to count as you can see in this film about the electric fishing survey by the Danish Techical University.
