caulerpa ! questions!

[andrew_kin]

hi

i read up on caulerpa n learned that when they go sexual, it kills inhabitant in the tank ... how do they go sexual?

anyway to prevent them from doing that?

if they are in the sump, will they be any damages?

how do they look like when they go sexual & any indication of them going to be sexual?

dont wan my tank inhabitant to die due to it!

thanks

 

[superswimmer]

have heard of peopel preventing them going sexual by keeping them lit 24/7.

usually you may see the formation of gametes, depending on the species.. maybe another way to keep them in check is to regularly prune it

ic
but lighting hem 24 7 only minimises the potential it goes sexual rite? there is still a tendency rite?

hmmm//// i think i might give my caulerpa away

Isn't there two types of caluerpa?
Do they both go sexual?

Greetings All !

Actually, there are many "types" (... i.e., species ...) of Caulerpa. All Caulerpa species exhibit both vegetative growth (asexual), and sexual reproduction (sporulation).

obarrera,

Since you're in San Diego, you might want to be aware of this:

ashmeadii, racemosa, verticillata, and scapelliformis.
(b) Notwithstanding subdivision (a), a person may possess, for
bona fide scientific research, as determined by the department, upon authorization by the department, the salt water algae of the Caulerpa species: taxifolia, cupressoides, mexicana, sertulariodes, floridana, ashmeadii, racemosa, verticillata, and scapelliformis.

So I can't keep any kind of caluarpa?(that's crazy!)

No ... Caulerpa prolifera and Caulerpa serrulata remain legal ... for the moment ... and are commonly available.

Crazy? Not in concept ... marine invasive species are a SERIOUS economic issue. If you have any doubts, do a quick web search regarding the "fun" folks living around the Mediterranean are having with Caulerpa taxifolia and its clones ... .

Crazy? That's a relative term when it comes to the California State Legislature ... more entertaining is their stance on transgenic freshwater ornamentals, but that's a whole different thread entirely ... .

Just our tax dollars hard at work ...

I didn't mean exactly crazy.But I mean like that's just stupid IMO.
If some other people can have it in other places then why can't we have it?

Anyways I do believe you,there's no need for me to look it up.

No it's not.
'Killer Algae' War Almost a Wrap, Except for the Plastic

The problem that started it all is called Caulerpa taxifolia, a leafy emerald-green Caribbean plant commonly used in saltwater aquariums because it's colorful and easy to grow. When released into new environments, a single stem, root or leaf can rapidly crowd out native plants and bottom-dwelling marine animals.

In the Mediterranean, the algae have infested more than 10,000 acres of sea floor off Spain, France, Italy and Croatia, ruining fisheries and clogging popular scuba diving sites.

Fearing the algae could do the same along the California coast, a coalition of state and federal agencies called the Southern California Caulerpa Action Team in 2000 launched a $5.2-million effort to combat two outbreaks of the algae, which wildlife officials believe were caused by people dumping their home aquariums into storm drains or directly in the ocean.

Facts about Caulerpa taxifolia

Prevention of new infestations: Aquarium water and other contents should never be emptied into or near any gutter, storm drain, creek, lagoon, bay, harbor, or the ocean. Aquarium water should be disposed of only in a sink or toilet. Rock and other solid material from an aquarium should be disposed of in a trash can. C. taxifolia from an aquarium (and anything it is attached to), should be placed in a plastic bag, put in a freezer for at least 24 hours, and then disposed of in a trash can. If any seaweed suspected to be C. taxifolia is found on fishing gear, anchoring gear, or vessels, it should be removed, carefully bagged (since even a small fragment has the potential to regenerate into a new plant), and reported. In order to prevent new infestations and comply with the law, Caulerpa taxifolia should not be purchased, sold, or distributed.

wow
glad this thread turn from a normal question about caulerpa caring to an important thread for advanced marine education

cheers ... great posts guys
keep em comin
