Abalone is a popular form of shellfish, prized in some parts of the world as a delicacy, and popular everywhere because of its beautiful iridescent shell which is used to make mother-of-pearl. Sadly, an invasive fan worm known as the sabellid has been taking up residence among the abalone production facilities of California, and these pests can inhibit or grossly deform abalone shells. But now, according to the Environmental News Network, researchers at the University of California, Davis, have found a way to nearly eliminate the worm by simply submerging the abalone in fresh water. Since this method destroys the worm and limits its spread in just 24 hours, what a difference a day makes!
