Epiphytes may limit distribution and productivity of seagrasses by reducing the light available to eelgrass blades (1). Primary production of eelgrass (Zostera marina) epiphytes increases with nutrients in the water column (2). In Waquoit Bay different estuaries are subject to different N loading rates from their watersheds. This offers the possibility of testing whether the accumulation of epiphytes increases as N supply increases. We investigated the growth of epiphytes on Z. marina in Sage Lot Pond (N load = 0.16 g [m.sup.-2][y.sup.-1]), Hamblin Pond (N load = 5.3 g [m.sup.-2][y.sup.-1]), and Jehu Pond (N load = 6.4 g [m.sup.-2][y.sup.-1]).
