UPPER LETHAL TEMPERATURE TOLERANCE OF FINGERLING BLACK CRAPPIE

Upper lethal temperature tolerance was determined for 26-81 mm, age 0 black crappie Pomoxis nigromaculatus of three size classes using both a rapid transfer and slow heating protocol. Rapid transfer protocols d etermined 24 LT(50) values of 33.8, 35.1 and 31.5 degrees C for size c lasses with mean total lengths of 30.2, 45.6 and 74.9 mm. A predictive model was generated from the slow heating protocols that relates leth al temperature to acclimation temperature, total length, and condition factor (K) as predictors.
