Undaria pinnatifida

(Harvey) Suringar, 1873


Nicolas Jouault Wakame - Undaria pinnatifida on a shellfish store box (nourrice) about a metre long.

Richard Lord Impressive. Have you tried harvesting it for food?

Nicolas Jouault I am sure if there was a market a Jerseyman would be exploiting it.

Richard Lord Hansa Health food shop sells wakame from Japan in Guernsey.

Andy Horton Seaweed picks up radioactive isotopes.

Andy Horton I have got to put a report on the web pages about this.

Nicolas Jouault Tried to trace the owner, but had no response I will try again.

Mickey Luv Abundant at the moment near Falmouth but find it hard to figure out what it is...Devil's tongue weed?

Gerard Heerebout Isn't it Undaria pinnatifida, Japanese wakame?

Mickey Luv I don't think so as it is red, not brown...

Angela Gall Probably devil's tongue weed, we do get it in the Fal. Is it slippery between your fingers? Forked? Could you press a bit to show the shape?
