我们报告了俄勒冈州海岸的一个牡蛎孵化场的结果，在2009年初夏，那里的进水口经历了不同的碳酸盐化学(文石饱和度从0.8到3.2；pH和7.6到8.2)。牡蛎幼体产量和中期生长(接近120~150亩m)与产卵和饲养前48h的水域文石饱和度呈显著负相关。初始产卵条件对仔鱼早期生长(从D-铰链期生长到接近120 mm)没有显著影响，表明水化学对仔鱼发育有延迟作用。
We report results from an oyster hatchery on the Oregon coast, where intake waters experienced variable carbonate chemistry (aragonite saturation state < 0.8 to > 3.2; pH < 7.6 to > 8.2) in the early summer of 2009. Both larval production and midstage growth (similar to 120 to similar to 150 mu m) of the oyster Crassostrea gigas were significantly negatively correlated with the aragonite saturation state of waters in which larval oysters were spawned and reared for the first 48 h of life. The effects of the initial spawning conditions did not have a significant effect on early-stage growth (growth from D-hinge stage to similar to 120 mm), suggesting a delayed effect of water chemistry on larval development.
