(Caulerpa taxifolia) Status: Eradicated This is a cautionary tale of an invader that took six years and more than $7 million to root out. Ten years later, the claim was made that Caulerpa had grown to cover 3,000 hectares (7,400 acres), and was preventing native plants from growing. This concern earned the algae the dubious nickname "Killer Algae" after the title of a book written on the subject. The Mediterranean clone of C. taxifolia was listed as a noxious weed in 1999[35] by the Animal and Plant Health Inspection Service, prohibiting interstate sale and transport of the strain without a permit under the Noxious Weed Act and Plant Protection Act.

As it is non-governmental organisations which usually start the complaint procedure, the Standing Committee has discussed several cases concerning invasive alien species, adopting recommendations on exotic crayfish, the alga Caulerpa taxifolia, the grey squirrel Sciurus carolinensis in Italy and the control of the Ruddy duck Oxyura jamaicensis: The role of habitat degradation on the spread of the alien green alga Caulerpa cylindracea is reported here by comparing observations achieved through a multi-year assessment on three Mediterraneans habitats, namely Posidonia oceanica meadows, Phyllophora crispa turf, and coralligenous reefs. bred! Think solar is expensive? The branch of genetics that is of major interest in aquaculture is "population genetics and animal breeding", which is based on the quantitative nature of the inheritance of most of the significant characters and the subtle inter-relationship that exists between the genetic make-up of an individual and its environment. Examples include striking recoveries of once-threatened species, increasing rates of protection of marine habitats, more sustainably managed fisheries and aquaculture, reductions in some forms of pollution, accelerating restoration of degraded habitats, and use .

Seahorses are considered at high risk as these fish represent an important component of traditional Chinese medicine but are also sold as curios and ornamental fish. Microalgae are used as food, feed, and fodder and also used to produce a wide range of metabolites such as, proteins, carbohydrates, lipids, carotenoids, vitamins, fatty acids, sterols, etc. Caulerpa taxifolia (aquatic plant) Common Names: caulerpa, Schlauchalge, sea weedCaulerpa taxifolia was introduced to the Mediterranean around 1984, possibly as waste from the Monaco Aquarium (Meinesz & Hesse, 1991). A 2007 study found that a native bivalve mollusc species was negatively affected by the presence of C. taxifolia, but that the effect was not necessarily different from that of native seagrass species. Baskin points to Asian long-horned beetles, kudzu, zebra mussels, West Nile virus, spotted knapweed, and caulerpa seaweed as just a few culprits.
