Abstract
    The benthic production of the lower Bay of Fundy, which has an area of 8620 km2, was estimated to be 166.7 x 104 t wet biomass in summer 1978, equivalent to an average benthic production of 193 g multiplied by m-2 multiplied by yr-1. Over 88% of the production was by suspension feeders of which the horse mussel, Modiolus modiolus (Linnaeus, 1758), was by far the largest contributor. The geographic distribution of production of the major, soft-sediment, epi- and infaunal trophic groups in the lower Bay fo Fundy was in general agreement with the hypothesis that tidal currents are a major determinant of benthic distribution and production in the lower Bay. Tidal currents control sediment dynamics, as well as settlement, growth, and feeding of benthic animals.
