Compared to the great scallop, the Pacific oyster has higher D larva yields (60% for C. gigas vs. 30% for P. maximus) and a faster larval growth rate (10 mu m.d(-1) for C. gigas vs. 5 mu m.d(-1) for P. maximus). However, Pacific oysters have a greater heterogeneity during larval development and higher mortality rates (40% far C. gigas vs. 25% for P. maximus) which produce lower overall yields of pediveliger larvae ready-to-set for Pacific oysters (15%) compared to the great scallop (30%). Development of continuous larval and post-larval culture methods along with development of continuous phytoplankton technology offers one of the most promising methods to improve molluscan hatchery techniques.
