My pond is around 1/4 acre. As for the number of LMB? Not sure. This is the 5th LMB that we've caught this spring. I've taken 2 of this size out of the pond. I've caught a couple 6-8 in LMB this past week. Just not sure on numbers. No, I didn't record weight, but will be in the future. I've just been doing length, which has been very interesting to say the least. I can say this, as I've asked questions and gotten responses, I have gradually learned a little bit more involving the various fish that are currently in our pond. Definitely looking forward to learning more.
