SS,
Although there are some biostitutes who can be bought, it's not usually that way. The "tilt" I mention might also be called selective science, and since there's at least two sides to most any story, favorable results are reported.
It might have gone like this: "Dr. Brannon, are there any examples of hatcheries successfully recovering wild or naturally spawning populations?" His job then, is to search the scientific literature and question his associates seeking an answer to the question. He wasn't asked to report on hatchery failures, and depending on his search, he might not find any of those examples. It's pretty clear that in his search, he found several examples that provide at least circumstantial evidence consistent with a "yes" answer to the question he was consulted on.
Academia may be an ivory tower, but a whole lota' the money that comes there has strings of one sort or another attached.
Further, most people read information through some kind of biased lens. I can write a report and get feedback that I'm being brutal to power companies, that I'm extremely objective and reasonable, and that I'm in the power company's hip pocket - all from the same work product. People are funny, and it keeps life interesting.
Sincerely,
Salmo g.
