Just a little update for anyone that may try this. I received these fish from Keo Fish Farms (great place!!) last June 21. I'm guessing they were 1.5" at most when I received them. You can see the process of raising them above. Last fall I stocked 30 of them in my yard pond, which is 2/3 of an acre and has a dense FHM population. I stocked around a thousand in my other lake. They were fairly quiet all summer, but lately have come to the feeder in a significant way. Last night I finally caught one in my yard pond. And it was an amazing 13.5". That's 12" of growth in 15 months.
