Scalation sequence and lengths at scale formation were determined for fry of three lake populations of salmon (Salmo salar). Scalation was complete for Sebago Lake salmon fry at lengths of 45 to 50 millimeters, 2 months after hatching. Average length of salmon with scales just formed was 32 millimeters. Size rather than age appears to determine time of scale formation. Linear regressions for scale length on fish length were calculated for each of four salmon populations. The body‐scale relationships so calculated all differed slightly. The possibility of using a generalized correction factor in direct proportion calculations of salmon lengths at previous annuli is discussed.
