If the 10 inch LMB were not original stockers then are you saying the original fingerlings grew large enough to spawn and that the spawn grew to 10 inches?
Yes. I had a pretty decent bass spawn in 2016. I culled as many of them as I could when they got big enough to bite, but couldnt get them all. Those fish would have been some of the "under 10's" I started culling in the fall of last year.
