Study: Shellfish Face High Risk From Ocean Acidification
As oceans become more acidic, the US shellfish business is facing “high economic risk” in 15 out of 23 coastal states, according to a study published Monday in the Nature Climate Change journal. Massachusetts tops the list of states facing the highest risk, the study concluded.
Shelled mollusks such as oysters, clams and scallops are extremely sensitive to ocean acidification, according to the paper. Those species represent lucrative fisheries, and a big part of the economy in coastal communities that depend on their sale. The US shellfish industry brings in $1bn annually, according to the report.
In the Southern Massachusetts fishery alone, shellfish makes up a $300m-per-year business, with the state giving out 1,350 commercial fishing licenses annually.
