This study certainly is a piece of work again by the usual suspects. Did it really take a study to come the the conclusion? Of course it was happening. But the study, if was really targeting salmon farms, should of used a wild processing facility as a control and they did not for the obvious reasons. They will find that the results are the same. Given this and the fact that this has been happening(with wild fish processing) for about 100 years one has to wonder what the effect has been. Maybe there is an effect. I am not saying there isn't. I am saying that the practice existed consistently for 70 or more years before salmon farming ever existed and it still exists today with commercial processing and sport fishing. Who does not bleed there fish where they caught it in the river or in the chuck? Salmon farmers are smart to take the precautionary approach and use filters to reduce/eliminate the potential risk if there is a risk. Who is going to follow their example?
I am glad that this study was done because it shows the intentions of the researchers involved and it is a prime example of what the peer review process is capable of producing. It certainly raises allot of questions.
