Abstract
1. Metabolic rates were highest during periods of maximum reproduction.
2. The exponent of the metabolic rate-weight equation varied seasonally, rates of metabolism of small animals exhibited greater annual fluctuations than those of large animals.
3. Absolute and weight-specific Q10s (determined at 5-10°C above field temperatures) for smaller clams were greatest in the winter; absolute values of Q10 were highest for larger individuals in the summer.
4. Small clams had Q10 < 1.0 in the summer; Q10-values for larger clams were near 1.0 at this time.
5. 38.9% of the total energy assimilated by the population annually was allocated to metabolism, which is near the low end of the range of values reported for freshwater molluscs, suggesting that this species can partition a large amount of energy to growth and reproduction.
