Control of Limnoperna fortunei fouling by oxygen deprivation

Abstract

The only detailed survey aimed at assessing the efficacy of oxygen deprivation for controlling fouling by the golden mussel indicates that, at dissolved oxygen levels < 0.16 mg/L, total mortality is achieved after 10-12 days (at 27 °C) to 21-29 days (at 20 °C). At 20 °C (but not at 27 °C), small (7 mm) mussels are significantly less tolerant than large (20 mm) individuals. Oxygen deprivation may be a viable alternative for the control of mussel fouling in industrial installations.
