Shellfish
In the past few years, near total failures of oyster harvests have been reported in aquaculture facilities on the West Coast. Its cause seems to be related with upwelling events that bring low pH waters deficient of aragonite near the shore. Although these are certainly natural occurrences, recent studies have indicated that man-made CO2 is contributing to the amount of acidification. There are other little-explored factors that might be causing these failures, including pathogen increases or low saturation of dissolved oxygen, and possibilities are still being investigated.
Similar occurrences had been observed in a scallop farm in 2010, where billions of aqua cultured microscopic larvae had died off in a matter of 10 days. The owner of the scallop farm eventually found that this was caused by increased pH levels, and control of carbon dioxide levels revitalized the farm.
