He fi rst noticed ocean acidifi cation impacts on larval production in 2009, when fertilized eggs periodically showed poor survival, deformities or stalled growth. "If you're producing millions and millions of seed to deliver to customers and for your own busi- ness, that's disruptive," he says. Mook solved the problem, and even got bigger yields, by monitoring and modifying the chemis- try of seawater pumped into the hatchery. But the experience "opened our eyes to changes that have occurred to seawater chemistry over the 32 years we've been in business," he says. at led, in 2013, to teaming up with University of New Hampshire oceanographer Joe Salisbury on a long-term project to understand how seawater chemistry continues to change and how it impacts calcifi cation, growth and survival of juveniles. e project deploys sophisti- cated sensors developed with funding from NOAA's Ocean Acidifi cation Program and Integrated Ocean Observing Systems Sensors. So far, they haven't seen any changes in growth or survival rates, although he considers it likely that ocean acidifi ca- tion is causing reduced calcifi cation rates. "It's important to not be reacting to a crisis when it occurs, but to be able to understand when that crisis will occur and have strategies in place to cope," he says. Meanwhile, Mook anticipates continued growth for his business and the industry in general. "What I think about is whether per capita consump- tion has scope for continued growth," he says. "I believe it does, because people like to eat oysters and we're still a long way from per capita consumption levels in the U.S. back in the late 1800s and early 1900s, or current per capita consumption rates in Europe."
