    A nested multiplex polymerase chain reaction (PCR) assay has been developed that allows the discrimination between six bivalve larvae common to Danish coastal waters (Cerastoderma edule, Macoma balthica, Mytilus edulis, Spisula subtruncata, Ensis americanus and members of the order Myoida). This assay involves the simultaneous use of a pair of general universally targeted 18S rRNA gene primers, five specific 18S rRNA gene targeted oligonucleotide primers internal (nested) to the universal primer pair and one species-specific primer that is not nested (Mya). The specificity of each primer was evaluated in silico, empirically, and verified further by sequencing of amplification products from single larvae collected from plankton samples. Identification of individually isolated bivalve larvae from plankton samples was based on the size of the PCR product produced by the specific primers after visualisation by agarose gel electrophoresis. Preliminary studies indicated that this method was suitable for use with freshly collected and preserved larvae, and is therefore suitable for field application.
