The preferred temperature and critical thermal maximum of Australian blacklip abalone, Haliotis rubra (Leach), and greenlip abalone, Haliotis laevigata (Leach), were found to differ only slightly; the blacklip abalone exhibited lower temperature tolerance and preference, as expected from its habitat distribution. Preferred temperatures were 16.9 and 18.9°C, and 50% critical thermal maxima were 26.9 and 27.5°C for blacklip and greenlip abalone, respectively. The optimum temperatures for growth calculated from each of these indices and averaged were 17.0 and 18.3°C, respectively.
