To investigate particle transport mechanisms on the bivalve pseudolamellibranch gill, the mucocyte secretion types and distribution were determined for this organ in the eastern oyster Crassostrea virginica, and related to previous endoscopic data. Three adult oysters were collected from Shediac Bay (New Brunswick, Canada) in July 1994, immediately fixed, then dissected and processed for histology and whole mount rnucocyte mapplng uslng a modification of the penodic acidSchiff-alcian blue protocol. One type of mucocyte contained acid-secretion rnucopolysaccharides (AMPS), while the other type contained neutral rnucopolysaccharldes (NhIPS). A clear grad~ent in nlucocyte density was observed from the plical crest to the trough; for all but the anteriorn~ost 15 plicae the proportions of each mucocyte type remained constant; the 15 anteriormost plicae presented an increased proportion of AMPS. These proportions would produce a relahvely viscous acid-dominant mucus after mixing on the c~liated gill surfacr. The principal filament troughs contained relatively few Inucocytes, aligned on the median ndge This arrangement could account for the observed range of partlcle velocities in these filaments. The results of the present study conform to a pattern of specialization of nlucus types and functions on the diverse types of bivalve gill, depending on particle trajectory, transporting surface architecture, and dominant current flow.
