Ocean Acidification Endangers Sea Scallop Fisheries

Each year, fishermen harvest more than $500 million worth of Atlantic sea scallops from the waters off the east coast of the United States. A new model created by scientists at the Woods Hole Oceanographic Institution, however, predicts that those fisheries may potentially be in danger.

As levels of carbon dioxide increase in the Earth’s atmosphere, the upper oceans become increasingly acidic—a condition that could reduce the sea scallop population by more than 50% in the next 30 to 80 years, under a worst-case scenario.  Strong fisheries management and efforts to reduce CO2 emissions, however, might slow or even stop that trend.

 The model, published in the journal PLoS One, combines existing data and models of four major factors: future climate change scenarios, ocean acidification impacts, fisheries management policies, and fuel costs for fishermen.
