I think they are doing Coho (Pacific Salmon, Silver Salmon) because they are no longer on the VHS list, and not susceptible to VHS.

I have often wondered how Coho would do in an appropriate pond environment.

I'll have to dig out my Salmon Culture books and read up again.

It would be pretty cool to catch a 5-10 lb Coho out of a pond on a light rig. Certainly not a King (Chinook), but these little bullets are fast, and they run! Much more than a RBT, Brook or Brown will ever think of. Could be fun for the right pond!
