dc.descriptionAbstract: Data are presented indicating that dewatering of fouled structures or source water drawdown is potentially efficacious for zebra mussel control. These strategies can expose mussels to lethal desiccation or freezing. Zebra mussels survive emersion < 3 days at temperatures ≥ 25°C (77°F) regardless of relative humidity (RH). However, as emersion tolerance increases exponentially with decreasing temperature and increasing RH, dewatering or drawdown is best applied during warm, dry summer months. Emersion tolerance was greatly reduced (LT100 < 10-40 hr) (estimated time for 99.9 percent sample mortality) at a lethal temperature of 35°C (95°F), which suggested that injection of heated air into dewatered structures would increase the mortality rate among emersed mussels. Freezing temperatures ≥ -3°C (27°F) caused rapid mussel mortality (LT100 ≥ 24 hr); thus, dewatering of mussel fouled structures when air temperatures are subfreezing shows promise as a mussel-fouling control strategy.-
