Indiana Boaters and Anglers Advised to Be Aware of Starry Stonewort Invasive

Boaters, kayakers, and other water-loving recreationists beware: starry stonewort is on the move. This invasive macro algae was first discovered in Indiana in Lake Wawassee in 2008, and has spread to more than 40 lakes across northern Indiana. Named after its star-shaped reproductive structure, or bulbil, starry stonewort can create dense mats along the bottom of lakes and rivers. It chokes out native plant species and reduces spawning areas for fish. The algae can spread through movement of bulbils or fragments, making it easy to accidentally transport when it catches onto boats and other watercraft.
