Juveniles of the abalone, <I>Haliotis discus</I> of 15 mm in shell length were fully fed on <I>Eisenia bicyclis</I> or <I>Ecklonia cave</I> for about 3 months (102 days) in various densities (340-920 juveniles / 0.48m<SUP>2</SUP>), and the number of survivors, shell length, and body weight were recorded. The rate of increase in shell length and in body weight was reduced with the increase in the population density, but survival rate remained constant. The biomass increased linearly up to the density of 660 juveniles / 0.48m<SUP>2</SUP> with some reduction in the rate of the increase in the highest density.
