The pH tolerance of oyster embryos and larvae as indicated by percentage of eggs that developed normally, survival of larvae, and increase in mean length of larvae. survival of larvae was to , whereas the range for normal embryonic devel- opment was only to In environments with a pH below , failure of clam eggs to develop normally would be the factor that would limit recruitment of this species. At pH levels and above the percentage of clam eggs developing normally, the percentage of larvae surviving, and the percentage increase in mean length all decrease abruptly, so that at high pH levels all three aspects of develop- ment limit recruitment of the species. Variations in the percentages of eggs devel- oping normally and of larvae surviving at pH levels between and were erratic, but all fell within the ± 10% confidence limits of our method. Although the pH ranges for normal survival of clam larvae were to and those for normal rate of growth were to , the optimum for growth was to The differences in rates of growth at pH to , however, were slight enough.
