| Summary, etc | This study aimed to determine the influence of microalgal species and food concentration=520 \\ |

| -- | margantifera and P maxima. Clearance rate, pseudofaecal production rate, absorption efficiency, respiration=520 \\ |
| -- | rate and excretion rate were determined over a range of food concentrations using 2 microalgal=520 \\ |
| -- | diets, Tah~tian Isochrysis sp. (T-Iso) and Dunaliella primolecta at 28'C. Clearance, pseudofaecal production=520 \\ |
| -- | and respiration rates were significantly affected by microalgal diet. From these results, and=520 \\ |
| -- | because of the higher energy content of T-Iso, pearl oysters feeding on T-lso had maximum values of=520 \\ |
| -- | SFG that were 1.5 to 2 1 times higher than when feeding on D. pnmolecta. Clearance rate and absorption=520 \\ |
| -- | efficiency were significantly related to food concentration as negative exponential relationships=520 \\ |
