We have developed a novel application for lipid-walled microcapsules (LWMs) in the potential control of sabellid infestations in abalone aquaculture. The use of LWMs takes advantage of the filter-feeding nature of the worms, versus the herbivory of the host abalone. Initial observations indicated that the pest was capable of feeding on particles ranging from 3-30 mu m in size. Lipid-walled microcapsules were prepared using different combinations of lipids (tristearin, tripalmitin, and fish oil) to encapsulate water-based solutions. Feeding experiments using worm-infested shells indicated that in a relatively short time (30-60 min) most of the worms (80-95%) fed on the LWMs …

Ecological risk assessment can be enhanced with predictive models for metal toxicity. Modelings of published data were done under the simplifying assumption that intermetal trends in toxicity reflect relative metal-ligand complex stabilities. This idea has been invoked successfully since 1904 but has yet to be applied widely in quantitative ecotoxicology. Intermetal vends in toxicity were successfully modeled with ion characteristics reflecting metal binding to ligands for a wide range of effects. Most models were useful for predictive purposes based on an F-ratio criterion and cross-validation, but anomalous predictions did occur in speciation was ignored in general, models for metals with …
