| Abstract | White suckers (Catostomus commersoni) were exposed from fertilization through hatching to seven constant temperatures from 6.2 through 24.1C. High percentages of apparently normal larvae hatched at temperatures from 9.0 through 17.2C. Maximum percent hatch occurred at 15.2C, while only a few normal larvae were produced at 6.2C, and none at 24.1C. Growth rates increased from near zero at 10.0C to a maximum at 26.9C. Lower 1-day TL50 temperature values for both groups of larvae acclimated to 21C were near 3C (<2.9), 2-day TL50 values were approximately 0.5C higher, and 7-day values were 4.8C for newly hatched larvae and 6.1C for swim-up larvae. |
