Abstract:

Experiments were carried out to determine the effect of an integrated ballast water treatment system on the mortality of zooplankton. This treatment system consists of 2 treatment stages: 1) the cyclonic pretreatment phase and: 2) the ultraviolet radiation phase. Various zooplankton species were exposed to the treatment system over a range of 6 ultraviolet dosages (UV-C). In general, both treatment phases exhibited significant effects on zooplankton mortality. The results revealed that clam, mussel, and oyster larvae exhibited statistically similar mortality thresholds ranging between 96% and 99% at the higher UV dosages. A significant difference was observed when comparing these results to the mortality thresholds of brine shrimp nauplii (77%) and a natural population of zooplankton (40%). These findings suggest that species grouped into similar taxa may exhibit similar mortality responses to ultraviolet radiation, while those taxa containing different structural tissues capable of different photoprotective properties may exhibit different mortality responses. In addition, time-dependent, post-treatment mortality observations varied according to the taxa present, demonstrating that biological assays should include time-dependent mortality estimates to accurately assess the efficiencies of ballast water treatment systems.
