Four Corners "Big Fish" This monday, page-80

Because of one claim from Huon and the subsequent 4corners report, I'm meant to question the credibility of:
- Tassal
- WWF Australia
- Aquaculture Stewardship Council
- Tasmanian goverment
- The EPA
- SeafoodIntelligence (see this announcement: http://www.asx.com.au/asxpdf/20151202/pdf/433jcdlddskdnn.pdf)
- the outcome of the senate enquiry

It seems far more probable that the report was inaccurate, rather than the probability that a number of otherwise very reputable organisations are all lying.

Sure, I don't have to pick one and could decide not to trust any of them. My point is, was the 4 corners report sufficient enough to question the credibility of the above
