I would estimate that I have around 5 LMB in the 15-18 inch size and the majority are 8-12 inch. This is a small 1/8 acre pond. I'm also wanting to stock some walleye, but have only been able to find smaller ones. I didn't know if there was a general guideline such as stocking 2x to 3xs as many fish if they're smaller into an established pond.
