5203 |a"Ascidiella aspersa, commonly known as the European sea squirt, is native to the Mediterranean Sea and Europe. The species has invaded far-off regions including Australia and the United States, and has been flagged as a possible invader to Atlantic Canadian waters. The main vector for its introduction is thought to be through ballast water or hull fouling. This solitary ascidian, which propagates through asexual and sexual reproduction, is a successful invader because of its rapid growth rate and tolerance of a wide variety of environmental conditions. Following its introduction to new habitats, this ascidian rapidly dominates the biological community, resulting in reduced biodiversity. The main control method is treating nets with copper, which has many negative effects on non-target species and the environment. This biological synopsis was prepared as a comprehensive collection of information"--Abstract, page iv.
