摘要：A set of feeding trials was carried out for different microalgal species and processed diets for the culture of the New Zealand pipi, Paphies australis . Five microalgal species ( Isochrysis galbana clone T-ISO, Pavlova lutheri , Tetraselmis suecica , Chaetoceros muelleri , and Thalassiosira pseudonana clone 3H) and three formulated diets (baker’s yeast, wheat flour, and corn flour) were fed to spat, juvenile, and adult pipi for 21 days. Unfed pipi were used in the control group. The spat and juvenile pipi showed the major shell increase with I . galbana , while the greatest wet weight increase was obtained with P . lutheri . The shells of adult pipi grew better with corn flour and P . lutheri -fed group obtained the greatest wet weight. Results of proximate analysis in adult pipi revealed that proteins and lipids were accumulated in the tissue for all fed groups, while carbohydrate levels depleted in all treatments including the control group. It is suggested that the gonads have developed during the experiment.
