Abstract

Six-day-old larvae of the catarina scallop, Argopecten ventricosus (=circularis), were infected with different concentrations of Vibrio alginolyticus to determine virulence and to describe vibriosis in this species. The development of vibriosis was compared to the effect of the supernatant of a 24-h V. alginolyticus culture. An experimental larvae culture system (ELCS) yielded a maximum survival of 80% from the 6th to the 19th day (control and low concentrations of V. alginolyticus). No effect was shown with concentrations of V. alginolyticus below 0.5 x 105 CFU ml-1. At concentrations higher than 5.0 x 105 CFU ml-1, swimming depletion, empty stomachs, lipidic granules in the digestive system, velum degradation, and massive mortality were observed. The supernatant of V. alginolyticus culture showed similar effects to the highest concentrations of V. alginolyticus cells.
