October 18, 2018 — David Ryan and Al Suprenant have a lot invested in their business.
The co-owners of Cape Cod Oyster Co. in Marstons Mills have eight full-time employees working 54 acres of ocean bottom on three sites; a 4,000-square-foot processing plant, two truck drivers, two bookkeepers, a fleet of refrigerated box trucks and five 28-foot vessels.
It takes careful planning, and a steady supply and demand for their product to keep it all rolling. They dread the reversals of fortune nature can dole out, such as occurred during a sudden onslaught of ocean acidification in the Pacific Northwest a decade ago that caused a 70 percent to 80 percent die-off of oyster larvae in Washington state hatcheries. One-quarter of the carbon in the atmosphere is absorbed by the ocean, forming an acid that inhibits shell building, particularly in larvae. Since the beginning of the industrial era 525 billion tons of carbon dioxide has been absorbed by the ocean, 22 million tons per day, according to a Smithsonian report.
“The West Coast was taken completely by surprise,” Ryan said Tuesday.
Washington was the largest aquaculture industry in the country with over 3,000 jobs but half the state’s production and hundreds of employees had to be relocated to Hawaii to avoid the acidic water that was delivered to the coastline by a slow-moving current.
Avoiding that kind of surprise in Massachusetts — where the aquaculture industry produced $28 million of oysters and other shellfish in 2017 — and in Barnstable County — with 270 licensed growers who produced over $12 million worth of shellfish — is why Ryan and Suprenant supported state Sen. Julian Cyr, D-Truro, and state Rep. Dylan Fernandes, D-Woods Hole, in their pursuit of legislation to create an Ocean Acidification Commission in the Bay State.
The commission is intended to foster research as well as legislative and other solutions to a problem often described as the evil twin of the global warming caused by climate change. On Tuesday, Cyr and Fernandes chose Cape Cod Oyster Co. headquarters to announce the official launch of the acidification commission, which was authorized under the latest state environmental bond bill this summer.
“This is a real challenge for our burgeoning aquaculture industry,” Cyr said, promising to leverage the power of state agencies, the wealth of research being done by the National Oceanic and Atmospheric Administration, Woods Hole Oceanographic Institution and Marine Biological Laboratory in Woods Hole, and the fishing industry to offset the effects of ocean acidification.
It’s not just aquaculture in state waters, but larger federal fisheries that are potentially in peril, including sea scallops and lobsters. Massachusetts harvested 29.2 million pounds of sea scallops in 2016 worth over $350 million. State lobstermen caught 17.7 million pounds of lobster worth $82 million.
The problem has not been well publicized because the effects occur out of sight, said Laurence Madin, WHOI vice president of research.
