As I know it, one of the main problems of reading scales is the ring production is not always consistent based on water temp and diet and the reader has to be objective as possible and has to be sometimes subjective in counting the crossing over marks. Lot of age rings on a smaller bass of 21 yrs (4.6lbs-20 in) puts the annuli and ridges of the scale rings very close together and quite difficult to see the true "crossing over" marks. Sometimes there are false crossing over marks. When the Ohio DNR switched to reading otoliths instead of scales for walleye, it made a big difference in the aging results. The scale method was considered inaccurate. Interesting.... Well as I said above, this aging changes everything for our pond. We had no idea there was LMB older then 6 years in the pond.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."

This is what we believe to be the same fish, last year. 9-4-15 at 16 inches 2.6 pounds. The marking on the gill is circled, this fish has same marking. Grew 4 inches and 2 pounds in just under a year.  Wow! What do you attribute the sudden growth spurt of this old fish to?

Grew 4 inches and 2 pounds in just under a year. Wow! What do you attribute the sudden growth spurt of this old fish to? GREAT Question Bill D.! After getting the aging report back, I don't believe this is the same fish. What a problem to have right?
