Abstract

Clearance and oxygen consumption rates of Ostrea edulis were measured at different temperatures (10-30 degrees C) in individual animals of a total weight ranging from 5 to 120 g (0.1 to 2.7 g dry tissue weight), outside the period of gametogenesis. For each temperature, the allometric relationship between the physiological response and dry tissue weight of the animal (DW)was estimated using the formula: Y = a * DWb. A statistical model is proposed for the variation in clearance rate or oxygen consumption rate (Y) withtemperature (T) and DW: Y = [a + (b * c(T))] * DWd. The calculated value for d was 0.62 for clearance rate and 0.74 for oxygen consumption rate. The rates of both physiological functions increased as the temperature increased and reached maximum levels at 30 degrees C (clearance rate:2.83 +/- 0.32 1 h(-1) g(-1) oxygen consumption rate: 1.78 +/- 0.23 mg O-2 h(-1) g(-1)) when the flat oysters were fed a Skeletonema costatum microalgal grown in underground seawater.
