Selected measurements and counts are given in Table 1. The largest previously recorded flathead chub, 317 millimeters ( inches) total length, was taken from the Peel River, Northwest Territories (McPhail and Lindsey 1970). The next largest specimen measured 290 millimeters ( inches) total length and was also Table 1 — Selected measurements (mm) and counts for a record-size flathead chub, Platygobio gracilis, captured in Lake Winnipeg, Manitoba Total length Standard length Fork length Body depth Head length Number of anal fin rays Number of dorsal fin rays Number of pectoral fin rays Number of pelvic fin rays Lateral line scales Scales above lateral line Scales below lateral line Age (years) 367 285 329 69 64 16 7 53 7 6 7 a^ mk^^^di.

Two large previ- ously recorded flathead chubs from Manitoba were a 294-millimeter fork length specimen from Kelsey Lake (ROMZ 13834) and a 250-millimeter total length specimen from Lake Winnipeg (ROMZ 16325). The latter specimen compares in size with a 230-millimeter standard length flathead chub take
