<div><p>Samples were collected by pumping 100L of water from specific depths and filtering the water through a 50 μm plankton net. Samples were preserved in ethanol. Bivalve veligers were sorted from other plankton and enumerated under a microscope. A random subset of approximately 33 veligers per sample were prepared for SEM and viewed. Veligers were identified to the family level based on previously published criteria for hinge tooth morphology and all veligers classified as mytillids were measured. Mytilus sp. veligers were distinguished from the much rarer Modiolus by established relationships between shell length and the number of hinge teeth. The total number of bivalve veligers was multiplied by the fraction identified as Mytilus sp. to yield the estimated number of Mytilus sp. larvae in each sample. This method did not allow us to distinguish Mytilus edulis larvae from Mytilus trossulus larvae, but the later species is rare in the bays that we sampled.</p>
