Interesting point, if not in the water column how else would the come in contact with fish for them to become infected? Now that I type that I suppose we have to take into consideration the food we feed, how can we garantee it's always free of harmful parasites, is keeping it frozen as long as possible enough? For instance venison, I always freeze for at least 60 days before consumption to ensure everything any 'buggies' have been eliminated.

As to the effectiveness of the UV, according to the literature they are super effective (we always read and know the literature couldn't be wrong). Need some pretty fancy equipment to really test them, and enough brains to use the equipment without creating some form of bio warfare...
