Commercial harvesters have found a decrease in four significant species of shellfish, the eastern oysters, northern quahogs, soft-shell clams, and northern bay scallops, between the coast of North Carolina to Maine. Clyde MacKenzie, a shellfish researcher for NOAA predicts the decline to be the consequence of warming ocean waters, which has increased their predation rate, being preyed upon earlier and longer into the fall. The fall in harvesting has led to stock falls, putting the U.S. at economic risk of increasing dependence on shellfish exports from other countries. Shellfish play a valuable role in the ecosystem and their population decline can lead to further environmental stresses that hurt more fishing industries, which is why clammers are currently seeking to adopt ‘new strategies, such as shellfish farming, for the fisheries to survive’.
