in Nantucket, MA: Sources, Production, Uptake, and Loss

was successful in providing some background information
regarding the uptake of domoic acid in the Nantucket Bay
scallop, Argopecten irradians, and it demonstrated
that domoic acid accumulates in the soft tissues of the
bay scallop fed on Pseudonitzschia pungens f.
multiseries. Preliminary data suggest that domoic
acid does not accumulate when the scallops' metabolic
activity and feeding activity are reduced. This
project was moderately successful in providing background
data on the distribution of the genus Pseudonitzschia.
Phytoplankton mapping has provided the occurrence of Pseudonitzschia
around Nantucket during 1992-3. Uptake of domoic
acid by bay scallops when feeding on toxic diatoms was
demonstrated for the first time.
