OWNERS WARNED TO LEAVE THEIR EXOTICS AT SEA

The Great Lakes are the largest body of fresh water anywhere in the world. Although they are protected by the locks between Montreal and Welland, deep sea ships have sometimes entered them with ballast water containing organisms in larval form. Examples are the ruffe, the spiny water flea and the zebra mussel, all of which--here called "exotics"--are proving extremely troublesome. Voluntary guidelines regarding ballast water have been introduced, aimed at preventing escalation of the problem. The Great Lakes are not alone in being under attack from imported exotics. Other sensitive marine environments in California, Australia and Norway have similar difficulties.
