TANGIER ISLAND, VA -- An explosion of feathery, orange, hairball-like blobs of algae this summer is frustrating crabbers and blanketing underwater grass beds in the southern Chesapeake Bay.
Watermen on Tangier Island report their crab harvesting grounds have been smothered with “red moss,” and complain they’ve never seen anything like it.
“It’s been around all summer -- and I mean loads of it, and it’s still growing,” said James “Ooker” Eskridge (pictured at right), mayor of Tangier and a commercial waterman for three decades. “The red moss gets so bad, you can’t work at all. You just have to leave the area.”
Some scientists say the menace is not moss at all, but a large multicellular algae, perhaps a species called Spyridia, which is native to the Chesapeake Bay. Others have speculated it could be a variety native to Asia called Gracilaria vermiculophylla. Researchers believe this latter macroalgae (big algae) probably hitchhiked from the Pacific Ocean to the U.S. in a ship’s ballast water.
