Abstract Thermal treatments for the control of mussel fouling can be applied in two different ways: (1) Water temperature can be gradually increased at a specific rate until target organisms die off (acute upper lethal temperature), or (2) animals can be exposed to a constant (high) temperature for periods long enough to achieve 100 % mortality (chronic upper thermal limit). Exposure of L. fortunei to temperature increase rates of 1 °C per 5, 15, or 30 min yields 100 % mortality after 1.8?15.3 h, at temperatures between 43.6 and 50.2 °C. In chronic treatments, at 34?36 °C total mortality takes 25.0?644.3 h, whereas at 38?43 °C all mussels die after 0.7?17.5 h.
