Thermal resistance of juvenile crayfish, Cambarus bartoni (fabricius): experiment and model

· Am. Midl. Nat.; (United States)
Juvenile crayfish, Cambarus bartoni, were subjected to acute thermal changes after being acclimated to temperatures of 15, 20 or 25 C for at least 1 week. Groups of 10 individuals each were exposed to various combinations of time and temperature, after which they were returned to their original acclimation temperature. Observations of latent mortality made 72 hr later indicated that some crayfish experience lethal temperature stress between 30 and 33 C; their ultimate upper incipient lethal temperature is estimated to be 32.5 C. A linear logistic model was used to construct contours of constant mortality (30, 50 and 90%) as a function of time and temperature.
