pearl oyster (Pinctada margaritifera L.) survival

This paper reports on an experiment to determine growth and survival of blacklip pearl oyster, Pinctada margaritifera (L.), larvae fed a 1:1 mixture of Isochrysis aff. galbana clone T-ISO and Pavlova salina at six different densities (1, 2, 5, 10, 20 and 30 X 103 cells ml-1). Larval growth and survival were assessed every 4 days over a 20 day period. Exponential and logistic regression models were fitted to the growth and survival responses, respectively. Overall growth of larvae fed ≥5 X 103 cells ml-1 was significantly greater (p < 0.01) than growth of larvae reared at other algal densities. The optimal food ration for maximum larval growth was 20 X 103 cells ml-1, which resulted in larvae with antero-posterior shell length of 230 μm after 20 days. These larvae were significantly larger (p < 0.05) than those in all other treatments at the end of the experiment. Survival of larvae fed 0, 1 and 2 X 103 cells ml-1 was significantly lower than that of larvae in all other treatments at the end of 15 days (p < 0.01). Maximal survival (8%) over the 20 day period was shown by larvae fed 10 X 103 cells ml-1, while lower survival was shown by larvae fed 2 X 103 cells ml-1(2%) and 1 X 103 cells ml-1 (0%).
