I do a lot of my fishing, well most of it, up at my cabin. We've got pike and walleye. I prefer walleye for the table but the pike is good too. I'd like to smoke some. I was going to hot smoke. I've been wondering what IT should the fish be at?
I've never checked.
I just cook it until the meat flakes and it looks done.
I go by flaking and looks (loses the opaque flesh look) but I think it is around 135 to 140 degrees. Fish will vary by about 10 degrees or so between the different species.
