Cecil,
What happened at John's place? Did he test positive for something?, and at both facilities?
John had a postive for IPN in his fingerling brown trout in the hatching building. He thinks it's a false positive as he doesn't bring in trout from any other sources and in all the years he's been there he's never tested positive. Even though he destroyed all the fish in the hatching building and sterilized it, he has to show he is clear of the virus for two or three years to sell trout again. I wasn't clear on whether he would retest immediately as the testing is very expensive.
Never mind IPN positive salmonids are common in Great Lakes and other trout, although it doesn't necessarily have any effect on them. My state has been known to plant IPN positive steelhead, and it wouldn't surprise me if other Great Lakes state do so also. I guess if you make the rules and enforce them you can do whatever you want.
