Abstract
Hatchery-reared Ostrea edulis and Crassostrea gigas seed grown in outdoor pumped upwelling systems show enhanced growth in water fertilized with N, P, and Si or N and P only compared to that in unfertilized water. The effect of water flow rate on growth depends on the amount of food in the water. Observations on filtration suggest that maximum feeding occurs at flow rates which produce about 20% filtration of suspended material passing through an upwelling column. Equations are derived which describe the relationship between filtration, flow rate, temperature, food concentration and oyster size. These offer an explanation for the variability of growth due to flow rate and food concentration and provide a means of managing flow to give maximum feeding and therefore maximum growth.
