Do you have age data on the small LMB (with big heads)? Obviously that size class is not getting enough to eat. If they are old and in that class, you need to take them out. Males while smaller do not have lower RWs (should not have) unless you are sampling post spawn.

This ,from Dr. Anderson who literally wrote the book on PSD and RW may help (from an old thread).

Read these threads on PSD for guidelines which include comments from the Prof who developed the concept Richard Anderson.

Keep taking <12 in bass until the number 8-12 equals number 12-15. Ideal pond structure is 40% 8-12, 40% 12-15 and 20% 15+
