Another tidbit. We sampled black crappies monthly in a fast-growing population in Lake Madison, SD. Following is the mean length of age-3 crappies each month.
Lengths in centemeters. cm/2.54 = inches
Mar 18.1 = 7.1 "
Apr 18.1
May 18.1
Jun 18.7
Jul 21.0
Aug 22.8
Sep 24.5
Oct 24.6 = 9.7"

Isn't that amazing? 7 inches to nearly 10 inches in just 3 months of growth. Crappies can really put on the feed bag.
