Abstract
The effects of body size, acclimation temperature, starvation and ambient oxygen tension on oxygen consumption rate and metabolic rate of the European abalone or ormer, Haliotis tuberculata L., were examined. An exponential relation was observed between dry tissue weight and oxygen consumption rate which varied with acclimation temperature and ration. The relation between standard oxygen consumption rate, tissue weight and acclimation temperature following a 14-day acclimation period for H. tuberculata was V O 2·0.06228·W 0.869·T 0.638 where VO 2 is oxygen consumption rate in ml O 2 h −1 and W is dry tissue weight in g. Ormers exposed to declining oxygen tensions at 16°C showed little ability to regulate oxygen consumption rate. Oxygen dependence was highest in small starved ormers and lowest in large fed individuals.
