ABSTRACT: The effect of increasing concentrations of Vibrio alginolyticus on survival of Mytilus galloprovincialis larvae was studied in a 48 h static bioassay in 1 l glass bottles. Five bacterial densities were tested ranging from 102
to 106 bacteria ml-1. Larval survival and normality (veliger larvae with the typical D-shape) were evaluated after 48 h. An inverse relationship between bacterial concentration and larval survival and normality was observed. In
spite of high larval survival (79%) under conditions of high bacterial density (105 bacteria ml-1), the percent of normal larvae was 11%. Besides an irregular shape, abnormal larvae also presented velum reduction. Results from this
study suggest that concentrations of V. alginolyticus lower than 103 bacteria ml-1 should be maintained during M. galloprovincialis larval culture.
