Resumo1.|Selected and avoided temperatures of acclimated Procambarus clarkii, juveniles, preadults and adults, were determined. 2.|Neither the different development stages nor the acclimation temperatures (20, 23, 26 and 29°C) had any effect upon the acute preferenda of crawfish. 3.|Procambarus clarkii final preferendum was 23.4°C. 4.|Avoidance thermal behavior was not influenced by size but acclimation temperatures did have a significant influence. The relative change of avoided temperature in respect to acclimation was narrower at high than at cold temperatures. 5.|The performance of crawfish from Baja California is closely related to higher latitudinal species as far as temperature is concerned.
