Salinity as a barrier for ship hull-related dispersal and invasiveness of dreissenid and mytilid bivalves.

The benthic stages of Dreissenidae and Mytilidae may be dispersed over long distances while attached to ship hulls. Alternatively, larvae may be transported by water currents and in the ballast and bilge water of ships and vessels. To gain insight into dispersal potential and habitat suitability, survival of the benthic stages of two invasive dreissenid species ( and ) and one mytilid species () chosen based on their occurrence in fresh, brackish and sea water, respectively, were tested in relation to salinity.

Thermal tolerance of the invasive oyster Crassostrea gigas: feasibility of heat treatment as an antifouling option.

Pacific oysters, Crassostrea gigas are traditionally considered shellfish of great fishery and aquaculture value. For these reasons they are introduced worldwide. Recently there has been increasing reports about the prevalence of C.

How effective is intermittent chlorination to control adult mussel fouling in cooling water systems?

Mussel control in cooling water systems is generally achieved by means of chlorination. Chlorine is applied continuously or intermittently, depending on cost and discharge criteria. In this paper, we examined whether mussels will be able to survive intermittent chlorination because of their ability to close their valves during periods of chlorination.
