Fisheries1

• NOAA Fisheries believes any species of Caulerpa that is allowed to establish and spread within coastal areas may adversely impact local fisheries and disrupt seagrass communities important to protected species. (noaa.gov)

Invasion1

• The eelgrass beds and other coastal resources that could be impacted by an invasion of Caulerpa are part of a food web that is critical to the survival of numerous native marine species, including those of commercial and recreational importance. (noaa.gov)

20021

Edible1

• Some species of Caulerpa are edible. (wikipedia.org)

Underwater1

Tropical1

• Caulerpa is mostly found in tropical regions, however its distribution may also extend up to temperate locations. (wikipedia.org)

Spread3

• Instead, Caulerpa spread far and wide, hitching rides from port to port on boat anchors and fishing gear. (croatia.org)
• It was made illegal to fish, dive, or anchor a vessel in affected areas as even small fragments of Caulerpa stuck to anchors, fishing gear, and trailers can potentially spread the infestation to other areas. (starboard.nz)
• This was of great concern, as frequent recreational boat traffic could have already spread Caulerpa to other parts of the country. (starboard.nz)

Habitat1

• On the other hand, for biological control it would be necessary to import some of the species that feed on Caulerpa in their natural habitat, such as gastropods. (scienceasker.com)

Found1

• Many studies on the life cycle of Caulerpa have been found to contradict each other, leading researchers to conclude that it varies with species and geographical region. (wikipedia.org)

Aquarium2

• If, God forbid, Caulerpa comes to San Francisco Bay on somebody's boat anchor or (discarded home) aquarium water, there are areas that are probably warm enough to support it," says Susan Williams, director of UC Davis' Bodega Marine Laboratory in Bodega Bay. (croatia.org)
• Further, after lengthy personal, face to face conversations with two officials, one being a specialist on caulerpa, they believe it is most likely the aquarium trade. (crew.org.nz)

Size1
