Spheroplasts (PS) were prepared by degradation of the cell wall of a low quality laver Porphyra yezoensis with enzymes, and were used for a new artificial diet for short-neck clams Ruditapes philippinarum. Short-neck clams in aquarium were given the PS diet or condensed natural diatom Chaetoceros gracilis for 45 days. The PS diet induced a superior nutritional effect on the growth performance and carcass composition of short-neck clams as good as the diatom. As results, PS was found to be a useful ingredient of new artificial diet for short-neck clam that can be substituted for live microalgae.
