Shermanater:
Below are references for some of the "primary literature" that you asked for and that supports Dave H's argument (hope it is OK I posted these here Dave H). Copy and paste them into Google and you will find Abstracts and more details.
Oglthorpe had no good points, except for the point that a “properly located and managed farm does not pose a threat to wild stocks”. This is true in my opinion, the problem is that farms are neither properly (i.e. so as not to pose a threat to wild stocks) located or managed here in BC.
And no I don't work for any of the David Suzuki/Sierra Club type organizations.
