Abstract
Studies of the biometric characteristics of paddlefish selects were conducted on specimens from the 6+ year class. They confirmed that the average female body weight was 13.6% higher than that of males and that the females had greater total length and body length (Lt and Lc) as well as longer heads (C) and rostrums (R). There was also a statistically significant difference in the absolute and relative values of the height of the pectoral (hP) and the pelvic fins (hV). The studied fish exhibited correlations between head length (C) and rostrum length (R) as well as between total length (Lt) and body length (Lc).
