Upp er lethal temperature tolerance of fingerling black crapp ie

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 determined 24 LT₅₀ values of 33–8, 35–1 and 31–5° C for size classes 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 lethal temperature to acclimation temperature, total length, and condition factor (K) as predictors.
