Abstract:	1. 1. Results of a study on lethal and sublethal responses of different size groups of the tropical brown mussel, Perna indica, when exposed to different temperatures are presented. 2. 2. Exposure to a temperature of 38°C showed 100% mortality of 9 mm size group mussels in 120 min. 3. 3. Mortality was dependent on age (size) of the mussels, young ones being more susceptible than older ones. 4. 4. All size groups showed a progressive reduction in physiological activities such as filtration rate, foot activity and byssus thread production when temperature was increased from 30°C. 5. 5. This study suggests that heat treatment is an attractive alternative to chlorination for mussel fouling control in tropical power stations.
