How big will the trout get from november to may? If pellet fed.
Max growth rate for trout in optimum temps is an inch and half a month. If your water temps stayed in the 50's for the most part you could get that.
I had rainbows and goldens in my pond last winter from late October through May. I was able to feed through about Thanksgiving, and them again from about Mid-March on. I didn't see any significant growth -- maybe an inch, to an inch-and-a-half at the most.
We love fish, but neither my wife nor I really cared for the trout. They were truly "fishy" tasting. My bluegill, bass, and catfish are always delicious.
But, they sure were fun to feed and watch.
