Relative weight charts are a much better indicator of the fishery health. A LMB can have enough food to reach a certain length, but once at that length they might not find enough food to eat, and will actually lose weight. When doing your charts, also include the weight of the fish. That will tell you if you need to remove "X" amount LMB of all sizes or just certain year (size) classes.

If the LMB are under say 90% WR for a particular length, then those are the fish that need thinning.

FWIW, even post spawn, LMB at 17" or so in my pond are still 3# - 3.25#.
