ABSTRACT-Two naturally occurring dinoflagellates, the autotrophic Prorocentrum micans and the hcterotrophic Noctiluca scintilldns (non-bioluminescent), ,ind the green alga Dunaliella tertiolecta were tested as prey for the first zoeal stage of the brachyurdn crab C'ancer magister under controlled laboratol-y conditions. Each dinoflagellate was tested alone and In combination with a suboptimal application of the nauplius of the brine shrimp Artemla s p . , a diet of known value. When offered alone, both dinoflagellates delayed mortality as compared to an unfed control, but neither supported development to the second zoeal stage. When larvae were fed a cycle of 1 d of Artemia sp. nauplii, followed by 2 d of either dinoflagcllate, survival to zoeal stage 11 was significantly higher than for larvae fed 1 d of nauplii followed by 2 d unfed. Indeed, survival was equal to a control that had been fed nauplii cont~nuously, although thcre was a significant delay in time to molt. Larvae fed D. tertiolecta in combinatlon wlth nauplii sho\ved a rc,duction in survival ils comparerl to the suboptimal nauplius dlet alone and no difference in time to molt. All 3 protists were consumrd and thc 2 dinoflagcllates contnbuted nutritionally Given the susceptibility of newly hatched brachyuran larvae to starvation, their abillty to prey upon protlsts may b e significant, especially for C. magister, a species that hatches in the Puget Sound (WA, USA) region in winter, a time of very low primary productivity. Crab larvae that can consume protistan prey may serve as a link between the rich carbon sources of the microbial food w e b and metazoans.

During oil spill incidents, NRDA and response activities may co-occur. This paper discusses those occurrences, focusing on ephemeral data collection and emergency restoration. Current laws provide some guidance for how these activities may be coordinated. The Field Operations Guide (FOG) and the National Contingency Plan (NCP) state that it is the responsibility of the Incident Commander (IC) to notify natural resource trustees of the incident and to coordinate NRDA representative's activities through the Liaison Officer. The FOG and NCP also state that it is the responsibility of the trustees to conduct their NRDA preassessment activities without hindering the response. The overlap between NRDA and response may be further complicated because many trustees may work within the environmental unit or the wildlife recovery unit for the response and also have the responsibility to work on NRDA. They may work in the Incident Command System advising the IC on response issues while also trying to initiate a damage assessment. Data collection during a response is critical for managing the incident as well as performing a thorough damage assessment. Although the types of data collected to aid the response may be similar to those used in damage assessment, often the scale and level of detail may be quite different. Even with these differences, synergies in ephemeral data collection may exist. Emergency restoration activities do sometimes occur before the response has concluded. The Oil Pollution Act regulations state that emergency restoration may occur if the action is needed to avoid the loss of natural resources, or to prevent any continuing danger to natural resources. If the trustees determine that emergency restoration is needed, they are required to consult with the IC prior to taking any such action. As an example, this paper will discuss emergency restoration actions undertaken during the Whatcom creek, WA gasoline spill to reduce the impact to migrating salmon.
