It upset the…. When zebra mussels colonize these historic shipwrecks, they quickly obliterate the construction details and structure of the wreck site. Filter tiny food particles out of the water, which can reduce available food for larval fish and other animals, and can increase aquatic plant growth as a result of increased water clarify. The Zebra Mussel, as the Quagga Mussel, was introduced to the Laurentian Great Lakes of North America via ballast water. They entered North America through the release of ballast water from shipping vessels traveling from Europe. Endemic bivalves are monoecious, dioecious or hermaphroditic, and some are internally fertilized by filtering sperm from the water column.
