I'm heading into my 3rd year with a little over 1/4 acre pond. Initially stocked with BG, HBG, RES, LMB and YP. Have feed since the beginning. Caught a few HBG (7-8") in the fall when trying to harvest the tilapia I put in. Feeding has been erratic the past couple of weeks but the weather has been all over the place. I rarely see the LMB other than a big splash sometimes in the evening during feeding time.

My questions how do I know what to harvest and how much?
