Providence Business News reports on the spread of red seaweed—actually an invasive algae that looks like matted hair—in the coastal waters off Rhode Island. The algae, which is native to Japan, began to bloom and spread in May.

According to the article, the algae was first observed in 2007 off Jamestown, but has now spread into Connecticut and Long Island and all the way north to Maine.

Commercial fishermen are complaining that the seaweed clogs their nets, and they must spend hours cleaning them. Further, the algae-infested areas are often devoid of fish. Rhode Island fishermen reported seeing the largest densities between depths of 40’ and 120’.
