In 2010, researchers found a new fish virus that was named piscine reovirus (PRV). Researchers at the Norwegian Veterinary Institute and NTNU University Museum have conducted a genetic analysis of the virus that demonstrates that the same PRV types are found both in farmed and wild fish.
This result shows that transmission of the virus between these groups probably occurs. But it is not easy to study virus in wild fish. "So far it has been a difficult area to do research on and only a few scientific papers are published in this field. This is probably due to the difficulty in catching sick wild fish for sampling because these fish usually die and disappear or are eaten by other animals", says Eirik Biering, a researcher at the Institute.
[...] "The main result of the genetic comparison is that wild and farmed fish infect each other with the virus. Transfer of infection can go both ways, but probably goes mainly from farmed fish to wild fish," she says. The reason is that there are far more farmed fish than wild fish and farmed fish to a greater degree carry PRV. In addition, we see that escaped farmed fish mix with wild fish in the rivers.

Maybe some background around the attempts by environmental groups to regulate fish farms with regards to polluting the sea and endangering the ocean's wild life would have been a better place to start the summary.

Or maybe we can let the two groups (fish and viruses) consult Darwin about the matter. The last thing we need is a bunch of anti-viral meds seeping into the water supply because some yahoo farmer wants healthier fish.
This is coming from a guy who has a well known vested interest in having healthy wild fish.
My rights don't end where your fear begins.

Too late. They're dumping antibiotics and hormones by the drum full as part of the fish's diet as opposed to treating outbreaks. It's why leaflets like these are released every other year: http://www.aces.edu/dept/fisheries/education/ras/publications/Update/Use%20of%20antibioticspdf.pdf [aces.edu]
Look up "fish hormones" or "fish antibiotics" in alibaba. They're soled as feed additives.

My eyes saw farmer, rather than farmed at first. I thought we had a much more interesting topic on our hnds.
