Abstract
Scales first developed on 13 mm juvenile bluegills along the midlateral line anterior to the caudal fin in the area of the caudal peduncle, squamation chronology continued anteriorly, and was completed in the dorsal area of the nape of 25 mm bluegills. Body‐scale relationships calculated from scales taken from three distinct body regions of adult fish were compared using both the Dahl‐Lea and the Fraser‐Lee methods. The calculated body length intercepts followed the chronology of the squamation and compared closely with the observed fish length at scalation of each area. The body length intercepts were different from one another and from the origin. There was little difference among the Dahl‐Lea and Fraser‐Lee calculated lengths beyond annulus one for the three distinct body regions. In all cases, however, results from the Dahl‐Lea method produced lower lengths than their corresponding values calculated by the Fraser‐Lee method. Selected size classes which omitted the smaller fish resulted in body length intercepts higher than those calculated from the total sample regression.
