Jim a friend of mine who fishes the hoosic frequently said the perch can be found on the NY side in the deeper pools.
Thanks for passing that along.
The news doesn't entirely surprise me, because I've also heard the smallmouth fishing is quite good further downstream on the Main Branch of the Hoosic in NY, near where it enters the Hudson.
But it doesn't really contradict the central "thrust" of my email to Ms. Fontaine, since when I was asking her about the "Hoosic," I was really referring to the MA stretches of the South (located entirely in MA) and Main Branches (which straddles MA, VT and NY).
(I was implicitly excluding the North Branch, which starts in VT and flows into MA, because I recognized it is too steep, fast and cold to support any game species other than trout).
