Figure 5. Effects of pH on the post-settlement (early juvenile) shell growth rate of the Pacific oyster (Crassostrea gigas).

The growth rates for each pH were calculated from days 5 to 12 post-settlement. Each data point represents the mean ± SD of three replicate cultures. For each replicate measurement, one to 20 juvenile samples were used. The statistically different mean values (Tukey’s multiple comparison test results) are indicated with different letters.
