Duckweed, Where to buy? Options

[iso7012003]

compare with Duckweed, my fish loves to eat this wasabi plants
a closer look of this wasabi

interesting i asked before and i was told in a different forum that there are different varieties of duckweed and the Japanese version is finer - is there 1 version of duckweed in Singapore and does duckweed biologically/technically refer to 1 type worldwide?

ps the photos with Mr Kashino - the duckweed looks too fine compared to the duckweed found in Sing; but also this (if) algae doesn't appear to disperse in the water when placed in it (like free floating algae)??

I think there are some 38 species of duckweed in the family of Lemnaceae of which Wolffia sp is the smallest(1mm).I am no expert in botancal science but we need to see the real thing to be sure whether you have in hand is algae or duckweed.

For those really want to read further this thread should set the mood for duckweed digestion

Wow.. this is indeed interesting.

Further probing into this, I realise I was wrong with the "藻" explanation. It can mean duckweed as well

仁丹藻 = Wolffia globosa, which is one species of duckweed family
( http://www.geocities.jp/conntextprex/siteki_kou.htm , scroll down to the bottom of page)

Iso, you're right that 仁丹藻 is indeed one member of the duckweed family. Sorry, I had caused you some confusion. .

The link which Doc posted indeed has very useful info on this kind of plants. A more precise one here (same website):

But it still does not mean that what Mr Kashino was netting back then in the pictures is this Wolffia globosa.

It has to be confirmed with Mr Kashino himself or someone near him... not from some guessing websites (as what we're doing it now ).

Like doc explained, there are plenty of species of duckweed. The one that iso has brought up (仁丹藻), is indeed a member of the duckweed family.

There are even more species (more than thousands) for algae. Some of them, like the blue algae which Doc brought up, are floating type. Some submerged algae, in the case of an algae bloom (harmful to environment), can cause floating scums too.

What Mr Kashino was netting in the picture back then, has yet to be confirmed. Perhaps Geert would have a better and closer answer to this... Maybe

PS: Incidentally, I have seen a few different kind of duckweeds in SG. But they are mostly large ones.

[goldrush]

Correct me if I'm wrong but to tell whether floating plants or floating algae One has to be close enough to observe carefully.Any forms of floating plant even the smallest Wolffsia has a portion of thallus(leaf like structure)above water while algae must thrive totally submerge in water even on surface(it gives the glistening effect which is reflective under the sun)Both must be verified in its water environment without being scooped up.
So Mr Kashino must tell us himself if not it would be still leave us baffled and dumbfolded as to whether that is algae or duckweed?

When Kashino-san comes to Singapore, ask him personally lor. Or maybe ask the thai student of Kashino-san, sure to know mah.

so confusing leh ...

Bro Samuel Phan once gave us some of the duckweed which he brought back from Thailand. Look like the ones iso is showing. Too bad I didn't manage to cultivate them.

I think even asking him may not be conclusive as you think ,as algae are so very often misquoted.Even my aircon service man says the algae accumulation is the cause of my blockage ..........Where got sun within our aircon system leh??????

Oh yes, although it was discovered in California, USA, a similar string of Wolffia globosa is known as "khai-nam" (water eggs) in Thailand and is consumed, well... as human food

Wah seem like you read thro the whole damn thread on Wolffia and are quite certain the whole truth of our discussion is confirmed.No more algae suspect?

Aiya, whether its algae, duckweed or chickenweed I think they all have more or less the same benefits ie enhance colouration and aids digestion.
So long as your goldfish have the luxury of feasting on any of those, its good enough.
