Deskripsi
The hatchery culture of bivalve mollusks depends on feeding with fresh microalgae which represent up to 50% of the production costs. We investigated the growth performance of juvenile <i>Ostrea edulis</i> and <i>Ruditapes decussatus</i> under 15% and 30% replacement of microalgae with <i>Saccharomyces cerevisiae</i>. Metabolic indices were measured along with weight-specific growth rate and condition index for 28 days. 15% substitution led to great results, whereas 30% yeast-fed treatments displayed poor growth and a depressed metabolism.
